Determinants of COVID-19 Vaccine Uptake and Hesitancy among Healthcare Workers in Tanzania: A Mixed-Methods Study

The novel Coronavirus disease 2019 (COVID-19) presents a major threat to public health but can be prevented by safe and effective COVID-19 vaccines. Vaccine acceptance among healthcare workers (HCWs) is essential to promote uptake. This study, aimed to determine the COVID-19 vaccination uptake and hesitancy and its associated factors among HCWs in Tanzania. We employed a convergent-parallel mixed-methods design among 1368 HCWs across health facilities in seven geographical zones in Tanzania in 2021. We collected quantitative data by using an interviewer-administered questionnaire and qualitative data, using in-depth interviews and focus group discussions. Participants in the quantitative aspect were conveniently selected whereas those in the qualitative aspect were purposively selected based on their role in patient care, management, and vaccine provision. Stata software version 16.1 was used in the analysis of quantitative data and thematic analysis for the qualitative data. Multiple logistic regression was used to assess the determinants of COVID-19 vaccine uptake. The median age of 1368 HCWs was 33, and the interquartile range was 28–43 years;65.6% were aged 30+ years, and 60.1% were females. Over half (53.4%) of all HCWs received the COVID-19 vaccine, 33.6% completely refused, and 13% chose to wait. HCWs aged 40+ years, from lower-level facilities (district hospitals and health centers), who worked 6+ years, and with perceived high/very high risk of COVID-19 infection had significantly higher odds of vaccine uptake. The qualitative data revealed misinformation and inadequate knowledge about COVID-19 vaccine safety and efficacy as the key barriers to uptake. Nearly half of all HCWs in Tanzania are still unvaccinated against COVID-19. The predominance of contextual influence on COVID-19 vaccine uptake calls for interventions to focus on addressing contextual determinants, focusing on younger HCWs' population, short working duration, those working at different facility levels, and providing adequate vaccine knowledge.

Acceptance of COVID-19 Vaccination Among Health Care Workers in India

Background: The coronavirus disease 2019 has been spread almost all over the world in the last two years, including in India. Vaccines are a critical tool in the battle against COVID-19, and India has flagged the largest vaccination drive on 16 January 2021. Although public acceptance was varying, which can lead to non-acceptance. Aim & Objective: To estimate an acceptance of the COVID-19 vaccine and its associated factors. Settings and Design: An analytical cross-sectional study among health care workers in India Methods & Material: It was conducted using a validated, self-administrated online survey questionnaire, and data were analyzed using SPSS 23 version. The outcome variable was healthcare workers' acceptance of a COVID-19 vaccine. Results: A total of 450 HCWs participated, including 205(45.6%) women and 245(54.4%) men. A total of 270 (60%) subjects will accept vaccines, while 33.3% were unwilling to accept and wait for vaccines. Male gender (OR=3.14), being married and experienced (OR=11.49), vaccine effectiveness (OR=6.4), vaccine safety (OR=3.4), and past history (OR=2.28) were significantly associated. On applying logistic regression for associated factors, gender (B= -1.145, S.E.= 0.200, Wald 32.748), being married (B= -1.482, S.E.= 0.216, Wald 46.937), for experienced (B= -0.865, S.E.= 0.200, effectiveness (B= -1.856, S.E.= 0.245, Wald 57.431), Safety (B= -1.224, S.E.= 0.202, Wald 36.633) and past history (B= -0.357, S.E.= 0.248, Wald 2.071) found significant. Recommendation: Proper information is crucial and healthcare workers' attitudes about vaccines are an important factor for acceptance and recommendation of the vaccine to the public for population-wide coverage.

A survey of public perception, knowledge and factors influencing COVID-19 vaccine acceptability in five communities in Ghana

Objective: The present study assessed the public's perception and Knowledge about COVID-19 and factors that could affect vaccine acceptability in Ghana. Design: We carried out a cross-sectional population-based study. A structured questionnaire was used to capture data on socio-demographic information, knowledge, and the public's perception of COVID-19 infection, as well as COVID-19 vaccine acceptability from consented participants. Factors affecting vaccine acceptability in Ghana were explored. Robust ordinary least square linear regression analysis was adopted to assess factors associated with vaccine acceptability. Setting: Five communities (Labone, Lartebiorkoshie, Old Fadama, Chorkor, and Ashiyie) in Accra in the Greater Accra district were selected. Participants: WHO modified cluster-sampling method was applied to select households of 997 participants in the five communities. Results: Most respondents were males (57.6%), and the median age of participants was 30 years. The study participants demonstrated a good knowledge of COVID-19 and had high perceptions of the COVID-19 pandemic. The results revealed that the highest educational level, marital status, self-rated Knowledge of COVID-19, Knowledge of COVID-19 definition, Knowledge of COVID-19 symptoms, and perception of the COVID-19 pandemic were significantly associated with vaccine acceptability. Self-reported impact of COVID-19 lockdown/movement restrictions on agriculture and job as a source of livelihood was associated with vaccine acceptability. Conclusion: Higher subjective and objective knowledge of COVID-19 increases vaccine acceptability scores significantly thus, education on COVID-19 and the vaccination against SARS-CoV-2 infection must be intensified to improve vaccine acceptability in Ghana, especially among those with lower educational backgrounds. © 2023 Ghana Medical Association.

Population-level impact of beliefs and attitudes on vaccine decision-making in South Africa: results from the COVID-19 Vaccine Survey (2021/2022).

OBJECTIVES: In addition to being home to more than seven million HIV-infected individuals, South Africa also has a high burden of COVID-19 and related comorbidities worldwide. We aimed to identify the most influential "beliefs" and "attitudes" on vaccine decision-making behavior. STUDY DESIGN: This study used panel data from cross-sectional surveys. METHODS: We used the data from Black South Africans who participated in the "COVID-19 Vaccine Surveys" (November 2021 and February/March 2022) in South Africa. Besides standard risk factor analysis, such as multivariable logistic regression models, we also used the modified version of population attributable risk percent and estimated the population-level impacts of beliefs and attitudes on vaccine decision-making behavior using the methodology in multifactorial setting. RESULTS: A total of 1399 people (57% men and 43% women) who participated in both surveys were analyzed. Of these, 336 (24%) reported being vaccinated in survey 2. Overall low perceived risk, concerns around efficacy, and safety were identified as the most influential factors and associated with 52%-72% (<40 years) and 34%-55% (40+ years) of the unvaccinated individuals. CONCLUSION: Our findings highlighted the most influential beliefs and attitudes on vaccine decision-making and their population-level impacts, which are likely to have significant public health implications exclusively for this population.

Zika virus knowledge and vaccine acceptance among undergraduate students in Guayaquil, Ecuador.

Purpose: Zika virus (ZIKV) was declared a Public Health Emergency of International Concern (PHEIC) in 2016. Concerns surrounding the effects of ZIKV persist today and several vaccine candidates are currently in various stages of development worldwide. There is limited research on ZIKV vaccine acceptability worldwide, and little research specific to Latin American countries. This research aims to identify the general beliefs and acceptance of a potential ZIKV vaccine in the undergraduate population at Escuela Superior Politécnica del Litoral (ESPOL) in Guayaquil, Ecuador. Methods: Between January and November 2019, 429 undergraduate students at ESPOL responded anonymously to a ZIKV vaccine survey. Frequencies, percentages, simple correspondence analysis, and bivariate inferential analyses were conducted using Kendall's tau-b test. Tests explored associations between likelihood of receiving a ZIKV vaccine and demographic, ZIKV information seeking, ZIKV psychosocial variables, and ZIKV information source variables. Results: Among the eligible participants, 241 (56.2%) were willing to receive a ZIKV vaccine if one was made commercially available. Most students were male (61.5%), age 20-25 (63.3%), and of mixed (Mestizo) race (95.3%). Results provided insight into student's knowledge on ZIKV, revealed television as the most common information source, and found most students were willing to receive a ZIKV vaccine were one to become available. Bivariate results revealed most respondents reported feeling neutral or likely to receive a ZIKV vaccine regardless of their agreeability with ZIKV information seeking behavior and psychosocial variables. Conclusions: This study provides insight into ZIKV knowledge among ESPOL university students and reveals most respondents obtained ZIKV related information from television. The most common reason for not wanting to receive a hypothetical ZIKV vaccine was vaccine hesitancy. Likelihood of receiving a ZIKV vaccine was associated with several information seeking behavior and psychosocial variables. Public health campaigns should focus on comprehensive ZIKV education efforts in this population.

A study on COVID-19 vaccine hesitancy among healthcare professionals in India

The novel coronavirus disease (COVID-19) was declared global pandemic in November 2019 and to combat the devastating impact researchers collectively organized to develop safe and effective vaccines and till date billion doses of vaccine were delivered. Aim – to assess Healthcare Professionals' (HCP) attitudes about vaccine safety, efficacy and acceptability of COVID-19 vaccine, a web-based cross sectional study was performed among HCP in a private tertiary postgraduate teaching and research setting at Chennai, India. Methods. A google forms survey was distributed by sharing the link among HCPs directly by authors through personal networks, professional associations and social media networks. Descriptive analysis was performed for demographic variables. Pearson Chi-square test was applied as appropriate. The level of significance was set to 0.05 (two-tailed). Results. 393 HCPs responded for the online survey of which nearly 60% were women. The mean age was 28.11 years with standard deviation of 10.23 years. Nearly half (44%;174/393) of the respondents felt that COVID-19 vaccine protects them and more men (50%;80/159) agreed about the protective effect of COVID-19. The univariate analysis yielded that there was significantly higher acceptance of COVID-19 vaccines by men (p=0.006), older respondents (p=0.029) whenever they are made available. Conclusion. The study revealed mixed response regarding acceptance of COVID-19 vaccine among health care professionals related to efficacy, safety and side-effects of the vaccines. The results emphasize the need for wider dissemination of national and regional guidelines about vaccination protocols in clinical and community settings. © Eco-Vector, 2022.

COVID-19 Vaccine Acceptability Among Healthcare Facility Workers in Sierra Leone, the Democratic Republic of Congo and Uganda: A Multi-Centre Cross-Sectional Survey.

Objectives: This cross-sectional survey explored COVID-19 vaccine acceptability among public healthcare facility workers in Kambia (Sierra Leone), Goma (Democratic Republic of Congo) and Masaka (Uganda). Methods: Questionnaire-based interviews conducted between April-October 2021 explored participants' knowledge and perceptions of, and attitudes towards, the COVID-19 pandemic and COVID-19 vaccines, as well as COVID-19 vaccine acceptability (defined as uptake of ≥1 dose or intent to get vaccinated). Results: Whilst most (n = 444; 81.8%) of the 543 participants had one or more concerns about COVID-19 vaccines, 487 (89.7%) nonetheless perceived that they were important for pandemic control. Most participants from Kambia or Masaka either were vaccinated (n = 137/355; 38.6%) or intended to get vaccinated (n = 211/355; 59.4%) against COVID-19. In Goma, all 188 participants were unvaccinated; only 81 (43.1%) participants intended to get vaccinated, and this was associated with positive perceptions about COVID-19 vaccines. In Goma, the most common reasons for not wanting a COVID-19 vaccine were concerns that the vaccines were new (n = 75/107; 70.1%) and fear of side effects (n = 74/107; 69.2%). Conclusion: Reported COVID-19 vaccine acceptability was high among healthcare facility workers in Kambia and Masaka. The lower vaccine acceptability in Goma may highlight the importance of social mobilisation and accurate, accessible information that addresses specific concerns.

COVID-19 vaccination acceptability and experiences among people who inject drugs in San Diego County.

Background: People who inject drugs (PWID) face increased risk of SARS-CoV-2 acquisition and severe disease, yet COVID-19 vaccine uptake has been suboptimal. To inform vaccination interventions tailored for the needs of this population, we explored COVID-19 vaccination acceptability and experiences among PWID in San Diego County, USA. Methods: From September-November 2021, we conducted qualitative interviews with PWID aged ≥18 years who were participating in a prospective study of infectious disease risks in San Diego. Thematic analysis of coded interview transcripts focused on identifying barriers and facilitators to COVID-19 vaccination. Results: Of 28 participants, 15 reported having had ≥1 dose of COVID-19 vaccine, primarily received through community health centers, pharmacies, jails, and homeless shelters. We identified three key barriers to COVID-19 vaccination: (1) low perceived risk of COVID-19 (or belief in natural immunity), (2) institutional distrust (e.g., of pharmaceutical companies and government agencies that "rushed" vaccine development, approval, and distribution), and (3) conflicting information from news, social media, and peers. We also identified three key facilitators of vaccination, including (1) heightened personal and interpersonal safety concerns, (2) health service outreach efforts to make vaccines more accessible, and (3) tailored information delivered by trusted sources (e.g., outreach or community health workers). Conclusions: Tailored intervention strategies to increase acceptability and uptake of COVID-19 vaccination among PWID should involve efforts to increase vaccine literacy and motivation while decreasing institutional distrust and structural barriers to access.

COVID-19 Vaccine Challenges in Developing and Developed Countries.

The coronavirus disease 2019 (COVID-19) pandemic has led to significant psychological and economical distress. Within a year after COVID-19 was declared a pandemic, several vaccines against COVID-19 were approved for emergency use. The journey from vaccine discovery to global herd immunity against COVID-19 continues to present significant challenges revolving around its development, affordability, accessibility, and acceptability at both a country level and an individual level. The main challenge faced by developed countries is the acceptability of the COVID-19 vaccine and the main challenge faced by developing countries is the affordability and accessibility of the COVID-19 vaccine.

COVID-19: knowledge, perception of risk, preparedness and vaccine acceptability among healthcare workers in Kenya.

Introduction: coronaviruses are highly contagious and healthcare workers are at a higher risk of contracting the disease. The objective of this study was to assess the level of knowledge, risk perception, preparedness for coronavirus disease 2019 and vaccine acceptability among healthcare workers in Kenya. Methods: a cross-sectional study was conducted from December 2020 to January 2021. A link to an online self-administered questionnaire was disseminated to health workers across the country. SPSS version 20 was used for data analysis. Bivariate correlation analyses were used to determine associations between variables. P-value of <0.05 was considered statistically significant.Results: a total of 997 participants were enrolled in the study. About half (53%) of the participants were female. The mean age was 36.54 years (SD = 8.31) and 46% of the participants were aged between 31-40 years. The overall knowledge score of health workers for COVID-19 was 80%. Most of the health workers (89%) perceived that they were at high risk of infection. Seventy-two percent of the participants felt that they were either partially or fully prepared to handle patients with COVID-19. Overall, 71% of all health workers would take a vaccine if provided free by the government. Conclusion: health workers´ knowledge on transmission, clinical manifestations and risk factors for development of severe COVID-19 was good. Majority of the health workers perceived the risk of infection with COVID-19 as high and a significant number felt that they were not fully prepared to handle the pandemic. Majority of health workers would take a COVID-19 vaccine.

Assessment of Knowledge, Attitude and Factors Influencing Uptake of COVID-19 Vaccine among Traders at Edaiken Market, Uselu, Benin City, Edo State, Nigeria.

BACKGROUND AND OBJECTIVES: Vaccination is a criticaltool in the battle against COVID-19, and a public health necessity in combating the pandemic. Challenges in getting the public to accept the vaccine may be due to vaccine hesitancy which may be caused by poor knowledge, poor attitude, ethical issues and safety concerns. The study aimed at assessing the knowledge, attitude and factors affecting the acceptability of COVID-19 vaccine among traders at Edaiken market, Uselu, Benin City, Edo State. METHODS: This was a descriptive cross-sectional study conducted among 400 traders using multistage sampling technique in Benin City, Edo State. A forty-one-item questionnaire was utilized to collect data. Data were analyzed with IBM SPSS version 25.0 and quantitative variables were expressed as frequencies, proportions, means and standard deviation. Level of statistical significance was set at p<0.05. RESULTS: A higher proportion (35.2%) of respondents were aged between 20 - 29 years of age and almost three-quarters (74.0%) were females, while 48.7% were married. Almost one-third, 30% of the respondents had good knowledge of COVID-19 and 375 (93.8%) had poor knowledge regarding COVID-19 vaccine. One-fifth (20.8%) of respondents had a positive attitude towards COVID-19 vaccine and 90 (22.5%) respondents did not know where to get the vaccine. CONCLUSION: Knowledge of COVID-19 vaccines was poor among the respondents, with most of them displaying a negative attitude to the vaccine. Knowledge of locations for obtaining vaccines was reported as a factor that would influence vaccine uptake. We recommend campaigns by public health authorities aimed at sensitizing the public about availability and importance of COVID-19 vaccine.

CONTEXTE ET OBJECTIFS: Les vaccins sont un outil essentiel dans la lutte contre le COVID-19 et une nécessité de santé publique dans la lutte contre la pandémie. Les difficultés à faire accepter le vaccin au public peuvent être dues à une hésitation à l'égard du vaccin et cela peut être causé par une mauvaise connaissance, une mauvaise attitude et des problèmes éthiques de sécurité. L'étude visait à évaluer les connaissances, l'attitude et les facteurs affectant l'acceptabilité du vaccin COVID-19 parmi les commerçants du marché d'Edaiken, Uselu, Benin City, Edo State. METHODES: Il s'agissait d'une étude transversale descriptive menée auprès de 400 commerçants à l'aide d'une technique d'échantillonnage à plusieurs degrés à Benin City, dans l'État d'Edo. Un questionnaire de quarante et un éléments a été utilisé pour collecter les données. Les données ont été analysées avec IBM SPSS version 25.0 et les variables quantitatives ont été exprimées en fréquence, pourcentages, moyenne et écart type. RESULTATS: Une proportion plus élevée (35,2 %) des répondants étaient âgés de 20 à 29 ans et près des trois quarts (74,0 %) étaient des femmes tandis que 48,7 % étaient mariés. Près d'un tiers, 30% des répondants avaient une bonne connaissance du COVID-19 et 375 (93,8 %) avaient une mauvaise connaissance du vaccin COVID-19. Un cinquième (20,8%) des répondants avaient une attitude positive envers le vaccin COVID-19 et 90 (22,5 %) des répondants ne savaient pas où se procurer le vaccin. CONCLUSION: La connaissance des vaccins COVID-19 était faible parmi les répondants, la plupart des répondants affichant une attitude négative à l'égard du vaccin. La connaissance des lieux d'obtention des vaccins a été signalée comme un facteur susceptible d'influencer l'adoption des vaccins. Nous recommandons des campagnes par les autorités de santé publique visant à sensibiliser le public à la disponibilité et à l'importance du vaccin COVID-19. Mots-clés: Adoption du vaccin, acceptabilité du vaccin, vaccins contre la COVID-19, connaissances, attitude, facteurs influençant l'adoption du vaccin.

Predictors of COVID-19 vaccine acceptability among health professions students in Vietnam.

BACKGROUND: The COVID-19 vaccine hesitancy or refusal has actually been a threat to global health. In the current situation, health professions students are at risk for SARS-CoV-2 infection during their internship at healthcare facilities. Furthermore, those future healthcare workers will advise people to accept the COVID-19 vaccination. Therefore, the attitude of students towards vaccine acceptance and the predicting factors needs to be elucidated. This study applied the Health Belief Model to determine predictors of COVID-19 vaccine acceptability among health professions students. METHODS: Nine hundred eleven students participated in a cross-sectional online survey in Vietnam. Data were collected from 1st April to 30th June 2021. Data analysis was performed using SPSS software version 20.0 with Chi-square and Kruskal-Wallis tests before executing multinomial logistic regression to identify predictors of the COVID-19 vaccine acceptability RESULTS: The overall vaccine acceptance, hesitancy, and refusal rates were 58% (95% CI: 54.7% - 61.3%), 40.4% (95% CI: 37.2% - 43.7%) and 1.5% (95% CI: 0.8% - 2.6%), respectively. Regarding vaccination hesitancy, a predictor such as "Receiving recent flu shots" had a negative correlation, whereas "Vaccines have little efficacy & serious adverse effects" (Perceived barriers), nationality, and majors were positive correlates. For refusal, "Unvaccinated students feasibly infected COVID-19 during hospital internship" (Perceived susceptibility) was a negative correlate. For predicting both hesitancy and refusal, "Mass media appreciating effectiveness and safety of vaccines" (Cues to action), and " Health professions students get serious complications of COVID-19 if not vaccinated" (Perceived severity) were negative predictors. In contrast, "Manufacturers do not disclose adverse effects of vaccines" (Cues to action), and "Adverse effect causes death" (Perceived barrier) were recognized as positive predictors. Strong Health Belief Model predictors of vaccine refusal were "Manufacturers do not disclose adverse effects of vaccines" (Cues to action) with OR= 5.299(95% CI: 1.687-16.641, p= 0.004), and "Adverse effect causes death" (Perceived barrier) with OR= 10.255 (95% CI = 3.528-29.814, p= 0.0005). CONCLUSION: Health professions students' acceptability of COVID-19 vaccination might be based on the perceived susceptibility to and severity of COVID-19, concerns about vaccine efficacy and safety, and the influence levels of information from various sources. Health education and measures to prevent the harmful effects of COVID-19 vaccine misinformation could potentially improve the acceptance rate of the COVID-19 vaccine.

University personnel and students’ perspective on COVID-19 vaccine acceptability

Vaccines are life-saving technology that has led to the eradication, containment, or control of infectious illnesses around the globe. Many factors affect the vaccine acceptability of an individual. Thus, this study was conducted to determine the coronavirus disease 2019 (COVID-19) vaccine acceptability and the willingness of the students, faculty and staff of Nueva Ecija University of Science and Technology (NEUST) to get vaccinated. A descriptive study approach and total sampling were adopted. A questionnaire was constructed to collect data on the respondents' profile, their source of information and statements regarding their acceptability and willingness to get vaccinated by the COVID-19 vaccine. Informed consent and permission to conduct were acquired. Various statistical tools were used to analyze the data. The vaccine acceptability was generally high and most was willing to get vaccinated. Their primary source of information was from television and social media on the internet. Their willingness to get vaccinated was influenced by their age, gender and the group where they belong in the university. Although more respondents are willing to get vaccinated, some still do not want to get vaccinated. Therefore, health education campaigns and vaccine promotion should be conducted to improve vaccine acceptance during the roll-out of the COVID-19 vaccine. © 2022, Intelektual Pustaka Media Utama.

Prevalence and factors associated with COVID-19 vaccine acceptance in Zambia: a web-based cross-sectional study.

Introduction: vaccinations against COVID-19 have been instituted to contain the pandemic. However, information about the acceptability of COVID-19 vaccines in Zambia is lacking. Therefore, the study assessed the prevalence and factors associated with COVID-19 vaccine acceptance among the general population in Zambia. Methods: this was an online questionnaire-based cross-sectional study conducted from 13th April to 21st May 2021. We included adult Zambians who had access to Facebook and WhatsApp. A multivariable logistic regression model was fitted to determine factors influencing vaccine acceptability. Data were analysed using Stata version 16.1. Results: of the 677 participants, only 33.4% (n = 226) would accept the vaccine if made available to them. In multivariable regression analysis, respondents who were older than 41 years compared to the 18 to 23 years age group (aOR: 2.77, 95% CI: 1.03-7.48), those who agreed (aOR; 22.85, 95% CI: 11.49-45.49) or did not know (aOR; 3.73, 95% CI: 2.29-6.07) compared to those who disagreed that the COVID-19 vaccine passed through all the necessary stages to ensure its safety and effectiveness, and those who were aware (aOR; 11.13, 95% CI: 5.31-23.35) compared to those who were not aware that the COVID-19 vaccine reduces virus transmission, were more likely to accept the vaccine. Conversely, entrepreneurs compared to government employees (aOR; 0.24, 95% CI: 0.07-0.79) were less likely to accept vaccination. Conclusion: awareness of the COVID-19 vaccine was high despite low acceptability levels. These findings are significant as they highlight the need to develop strategies for improving vaccine acceptability in Zambia.

COVID-19 vaccine acceptability among healthcare workers in Ethiopia: Do we practice what we preach?

OBJECTIVE: We assessed healthcare workers (HCWs) COVID-19 vaccine acceptability in Ethiopia. METHODS: We carried out a cross-sectional survey from February to April 2021 in HCWs from five teaching hospitals. HCWs were selected using convenient sampling, and data were collected through a survey link. Descriptive analysis and mixed-effect logistic regression were performed. A total of 1,314 HCWs participated in the study. RESULTS: We found that 25.5% (n = 332) of the HCWs would not accept a COVID-19 vaccine and 20.2% (n = 264) were not willing to recommend COVID-19 vaccination to others. Factors associated with vaccine non-acceptance were female sex (AOR = 1.8; 95% CI: 1.3-2.5), the perception that vaccines are unsafe (AOR = 15.0; 95% CI: 8.7-25.9), not considering COVID-19 as health risk (AOR = 4.4; 95% CI: 2.0-9.5) and being unconcerned about contracting COVID-19 at work (AOR = 3.5; 95% CI: 1.5-8.4). Physicians were more willing to accept vaccination than other HCWs. Higher vaccine acceptability was also noted with increasing age. Participants most often indicated safety concerns as the determining factor on their decision to get vaccinated or not. CONCLUSION: Overall, a quarter of HCWs would not accept a COVID-19 vaccine. Communications and training should address vaccine safety concerns. Additionally, emphasis should be given to showing current and future impact of COVID-19 on the personal, public and country level unless control efforts are improved. Interventions aimed to increase vaccine uptake should focus their efforts on younger and non-physician HCWs.

Exploring perceived risk for COVID-19 and its role in protective behavior and COVID-19 vaccine hesitancy: a qualitative study after the first wave.

BACKGROUND: The novel coronavirus pandemic (COVID-19) has had severe impacts on morbidity and mortality globally. METHODS: This study was set in rural central Kentucky and included participants recruited from public spaces. Fifteen qualitative interviews about personal experiences during the COVID-19 pandemic were conducted by phone from July 3 to July 24, 2020. Interviews were recorded, transcribed, and coded using a grounded theory approach. RESULTS: Participants who perceived COVID-19 to be a severe risk tended to have personal health concerns and therefore reported taking protective measures for themselves. A slightly smaller proportion of participants reported taking measures to protect others (particularly family). A minority of participants had an ambivalent attitude towards the risk and only took measures if required. COVID-19 vaccine acceptability was low with most participants expressing concerns regarding their need for a vaccine, safety of this vaccine, the value of personal rights, or future vaccine supply. CONCLUSIONS: Most participants perceived some risk of COVID-19 and took steps to prevent infections in themselves and others. Mandates for mask use in certain locations were additionally useful for those who had an ambivalent attitude towards the risk of illness. There was surprisingly little connection between perceiving COVID-19 risk and a desire for the COVID-19 vaccine. In this setting, vaccine acceptability was low, with vaccine concerns outweighing perceived potential benefits. In conclusion, because the risk was often constructed in terms of worries for themselves and others, the framing of health education materials for protective behaviors in these terms may be effective. Furthermore, future COVID-19 vaccine education should address vaccine knowledge and concerns, such as the need for a vaccine and its safety, and emphasize how a vaccination would reduce their chances of severe disease if they were to get sick.

Predictors of COVID-19 Vaccine Acceptability among Patients Living with HIV in Northern Nigeria: A Mixed Methods Study.

BACKGROUND: People living with HIV (PLHIV) are at increased risk of COVID-19 acquisition, severe disease, and poor outcomes. Yet, little is known about COVID-19 vaccine hesitancy among PLHIV in high HIV burden countries, such as Nigeria. OBJECTIVE: This study aims to assess the acceptability of the COVID-19 vaccine and identify predictors and reasons for vaccine hesitancy among patients living with HIV and attending a tertiary hospital in Kano, northern Nigeria. METHODS: Using a mixed-methods design, structured questionnaires were administered to a clinic- based sample of patients living with HIV (n = 344), followed by 20 in-depth interviews with a sub-sample. Logistic regression and the framework approach were used to analyze the data. RESULTS: Less than half (46.2 %, n = 159) of the respondents were willing to take the COVID-19 vaccine. Vaccine acceptance was higher among non-Muslim PLHIV (Adjusted Odds Ratio (aOR) = 1.26, 95 % Confidence Interval (95 % CI): 1.10-4.00), persons with high-risk perception (aOR = 2.43, 95 % CI:1.18-5.00), those who were not worried about infertility-related rumors (aOR = 13.54, 95 % CI:7.07-25.94) and persons who perceived antiretroviral drugs are protective against COVID-19 (aOR = 2.76, 95 % CI: 1.48-5.14). In contrast, vaccine acceptance was lower among persons who were not concerned about the potential effects of COVID-19-HIV co-infection (aOR = 0.20, 95 % CI:0.10-0.39). The most common reasons for vaccine hesitancy included doubts about the existence of COVID-19, low-risk perception, anxiety about antiretroviral treatmentvaccine interactions, safety concerns, and infertility-related rumors. CONCLUSION: Covid-19 vaccine acceptance was low among PLHIV. COVID-19 vaccine acceptance was associated with respondents' faith, risk perception, perception of the protective effects of antiretroviral treatment, concerns about COVID-19-HIV co-infection, and infertility-related rumors. Vaccination counseling should be integrated into HIV treatment services to improve COVID-19 vaccine uptake among PLHIV in Kano, Nigeria and similar settings.

Using Best-Worst Scaling to investigate younger adult Canadians' preferences for COVID-19 vaccination and public health measures: An observational study.

Containing the COVID-19 pandemic is dependent on compliance with public health recommendations and mandates which is lower in younger compared to older adults. Furthermore, younger adults have demonstrated lower uptake of COVID-19 vaccines. The aim of this study was to assess preferences for COVID-19 related preventive health measures and vaccination and to explore their association with COVID-19 vaccine acceptability. Canadians aged 18-39 years were invited to participate in a web-based survey in August 2021. We used the Best-Worst-Scaling (BWS) methodology to collect and analyze preference data and multivariable binary logistic regression to estimate associations with vaccine acceptability. Based on 266 complete responses, we found strong preferences for physical distancing and wearing face masks, as compared to general hygiene and respiratory etiquette. High vaccine accessibility independent of the location, receiving successive doses of the same vaccine brand and higher vaccine uptake of people in younger adults' social circle were highly preferred. Higher preferences for mandates requiring proof of vaccination and altruistic motives focused on protecting others by getting vaccinated were associated with vaccine acceptability. As the COVID-19 pandemic waxes and wanes, studies using larger, nationally representative samples are needed to replicate and validate these results to assess preferences for health behaviors corresponding to the latest recommendations. The use of this methodology could provide public health authorities with a unique opportunity to develop targeted, preference-based messaging that aligns with the latest guidelines to effectively encourage compliance and COVID-19 vaccine uptake.

COVID-19 Vaccination Willingness and Acceptability in Multiple Sclerosis Patients: A Cross Sectional Study in Iran.

Multiple sclerosis (MS) is a chronic, predominantly immune-mediated degenerative disease of the central nervous system. Due to prolonged use of immunomodulatory and immunosuppressive medications, vaccine hesitancy could be common among MS patients. Our main aim in the current study was to evaluate the willingness and acceptability of COVID-19 vaccination in patients with MS. In our multicenter cross-sectional questionnaire-based clinical study, 892 patients completed the questionnaire between May to June 2021. The questionnaire consisted of demographic data, MS disease-related factors, history of COVID-19 infection/vaccination, and any existing comorbidities. Statistical analysis was performed using SPSS software version 19. Overall, 68% of the participants expressed willingness to be vaccinated. Major causes of vaccine refusal in our patients were the fear of reducing the efficacy of disease modifying drugs (DMDs) upon vaccination as well as distrusting the vaccines and overestimation bias in the power of their innate immunity and potential COVID-19 resistance. Some demographic factors affected vaccination enthusiasm in our study. Our findings did not show significant correlation between the age and comorbidity and vaccine willingness. Only one-third of our patients received their vaccine information from healthcare providers. The majority of them received these data from official broadcasting channels and social media. However, despite several concerns, the willingness of COVD-19 vaccination in the Iranian MS patients is remarkable.

Acceptability of covid-19 vaccine among frontline health care workers in north central and south western, nigeria

OBJECTIVE: To explore the acceptability of COVID-19 vaccines among frontline health workers in Nigeria. METHODOLOGY: A descriptive cross-sectional multi-centre survey was conducted among 115 randomly selected frontline health workers in two tertiary health facilities;Federal Medical Centre Abeokuta (South-Western, Nigeria) and University of Ilorin Teaching Hospital (North Central, Nigeria). The inclusion criteria were Frontline Healthcare Workers over the age of 18 years who gave consent for the study, while other hospital workers were absent from work and those unwilling to participate in the study. Data analysis was done using SPSS version 23. RESULTS: Accordingly, 59.1% of respondents accepted to be vaccinated with the COVID-19 vaccine when it becomes available. The level of acceptance increased with the effectiveness and safety of the vaccine. More respondents were also willing to wait 6 months to receive the vaccine than those willing to accept the vaccine at the moment. The age of respondents was statistically significant in the willingness to accept the vaccine. CONCLUSION: The acceptability of the COVID-19 vaccine among health workers increased with the effectiveness of the potential vaccines as well as the duration of vaccine usage.
