COVID-19 vaccine acceptance among pregnant women: a multicentre cross-sectional survey in Port Harcourt, Nigeria

Introduction: effective COVID-19 vaccines for the prevention of severe illness have been available for more than one year now. This study was carried out to ascertain vaccine hesitancy and its associations among pregnant women receiving antenatal care in Port Harcourt, a large cosmopolitan town in Nigeria. Methods: we conducted a cross-sectional online survey over 2 months among consenting pregnant women receiving antenatal care in the 3 largest obstetric service centers in Port Harcourt to evaluate COVID-19 vaccine hesitancy and its associations. Results: the prevalence of vaccine hesitancy was 669 (72.2%). Of the respondents, 27 (2.9%) had been infected or had a close family member infected with SARS-CoV-2, and 897 (96.8%) of them had heard of the COVID-19 vaccine; however, only 133 (14.4%) had been vaccinated against COVID-19. The safety of the mother in 260 (32.8%) and the safety of the unborn baby in 114 (14.4%) of the respondents were the reasons for vaccine hesitancy. A small proportion of women 7(0.9%) were hesitant on religious grounds. Tertiary education, use of childhood immunization for previous infants delivered, and availability of COVID-19 vaccine in the antenatal clinic at no cost to the women, were statistically significant predictors of vaccine uptake among the respondents. Conclusion: the prevalence of vaccine hesitancy among pregnant women in Port Harcourt was 72.2%. Higher academic achievement and availability of the COVID-19 vaccine in the antenatal clinic were predictors of vaccine uptake, while reasons for hesitancy were mostly due to safety concerns for the mother and unborn baby.

COVID-19 vaccine hesitancy among pregnant women in an antenatal clinic in Durban, South Africa

Background: Mass administration of vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the most efficient intervention against the coronavirus disease 2019 (COVID-19) pandemic. Recently, vaccinations were shown to be safe and effective during pregnancy. However, vaccination rates are low in low- and middle-income countries, and vaccine hesitancy is a major limiting factor. Objectives: To investigate the rate of COVID-19 vaccine hesitancy among pregnant women. Method: A cross-sectional questionnaire-based investigation of 313 unvaccinated pregnant women attending an antenatal clinic in Durban, South Africa (SA). The questionnaire included clinical and socio-demographic data, and reasons for vaccine hesitancy were recorded and evaluated. Results: Of 313 women participating, 126 (40.3%) were vaccinated against COVID-19, 21/313 = 6.7%; for those unvaccinated, 21/187 (13.9%) were planning to be vaccinated. However, most unvaccinated women, 174 of 187 (93%), showed COVID-19 vaccine hesitancy. Conclusion: The COVID-19 vaccination hesitancy among pregnant women in Durban, SA, is exceptionally high. This requires urgent attention by the relevant health authorities (both professional health organisations and the SA Department of Health) as many countries experience different waves of the variants of SARS-CoV-2 and herd immunity may not have been achieved. Contribution: This study showed a high vaccine acceptance hesitancy rate among pregnant women in SA.

Factors associated with COVID-19 vaccine hesitancy among health personnel in Yaounde, Cameroon

Background. Health care personnel constitute a group at high risk of contracting COVID-19. However, the vaccination rate in this group in our context remains low. The objective of our study was to determine the factors associated with COVID-19 vaccine hesitancy among health care workers in Yaounde. Methods.We conducted a cross-sectional study of 360 health personnel in three hospitals in the city of Yaounde from January to March 2022, i.e., 3 months. All health personnel who gave their free consent were included. Ethical clearance was obtained from the Institutional Ethics and Research Committee of the Faculty of Medicine and Biomedical Sciences of the University of Yaounde I. A logistic regression was performed to search for factors associated with reluctance to vaccinate, with a significance level of 0.05. Results.The vaccination rate against COVID-19 was 34% (123). Factors associated with vaccine hesitancy were female gender (OR [95% CI] =3.5[2.2-5.5]; p<0.001), working outside a COVID-19 management unit (OR [95% CI]=6, [2.1-18.5]; p=0.001), fear of the harmfulness of COVID-19 vaccines (OR [CI 95%] =2.7[1.7-4.2]; p<0.001), and doubt of vaccine efficacy (OR [CI 95%] =4.0[2.5-6.4]; p<0.001). Conclusion:Health personnel are still reluctant to vaccinate in our context. Factors associated with hesitancy to vaccination against COVID-19 could help deconstruct apprehensions.

Introduction. La pandémie de la COVID-19 a ajouté un fardeau supplémentaire dans les pays aux systèmes de santé déjà fragiles. Objectif : déterminer la prévalence et la séroprévalence de la COVID-19 en cas de suspicion du paludisme au cours de la deuxième vagueà Yaoundé. Méthodologie. Une étude transversale descriptive a été menée au Centre Médical le Jourdain pendant 8 semaines du 19 Avril au 13 Juin 2021 soit durant la deuxième vague au Cameroun. Pour les 86 patients avec suspicion de paludisme, des prélèvements nasopharyngé et sanguins ont été réalisés pour la recherche d'antigène du SRAS- CoV 2 et des IgG et IgM anti-SARS-CoV-2 grâce aux kits STANDARDTM Q COVID-19 Ag de SD BIOSENSOR, Corée, 2020 et StandardTM Q COVID 19 Ac IgG/IgM de SD BIOSENSOR, Corée, 2020 respectivement. La confirmation du paludisme a été faite grâce à l'examen microscopique des étalements de sang colorés. Résultats. Le paludisme était confirmé dans 20,9% (18) des cas. Les prévalences de la COVID-19 et de la coïnfection COVID19/Paludisme étaient de 8,1% et de 0,9% respectivement. Sur les 25,6% (54) des patients avec des IgM anti-COVID-19, aucun cas de microscopie positive n'a été retrouvé. Par ailleurs un peu plus de la moitié des patients avaient des anticorps IgG anti-COVID-19 qu'ils aient une goutte épaisse positive ou pas soit 56,0% (42/75) et 52,2% (71/136) respectivement. Conclusion. En cas de suspicion du paludisme en zone impaludée, il parait non négligeable de considérer la COVID-19 comme un diagnostic différentiel.

Assessment of COVID-19 vaccine hesitancy among people living with HIV/AIDS: a single-centered study

Introduction: as the coronavirus disease 2019 (COVID-19) vaccines are distributed and administered globally, hesitancy towards the vaccine hinders the immunisation of a significant number of vulnerable populations, such as people living with HIV/AIDS. Hence, this study aims to assess COVID-19 vaccine hesitancy among people living with HIV/AIDS (PLHIV) attending clinicaloutpatient follow-up at State Specialist Hospital Maiduguri (SSHM), Borno State, Nigeria. Methods: a hospital-based cross-sectional study design was conducted to assess COVID-19 vaccine hesitancy among 344 PLHIV receiving antiretroviral therapy (ART) at the United States President´s Emergency Plan for AIDS (PEPFAR) clinic in SSHM from 4 th January to 25th February 2022. Data were collected using a structured and pretested interviewer-administered questionnaire. The results were presented using frequencies and percentages. The factors that are associated with COVID-19 vaccine hesitancy were identified using the Chi-square statistical test. Results: among the 344 respondents of the study, only 88 (26.6%) received the COVID-19 vaccine. Out of the 256 respondents that did not receive the vaccine, only 10.5% (27/256) are willing to be vaccinated, while the majority; 57.8% (148/256) are not willing to be vaccinated and 31.7% (81/256) of the respondents are uncertain, thus resulting in a hesitation rate of 89.45%. There was no statistically significant association between COVID-19 vaccine hesitancy and the study´s independent variables; where p-value is greater than 0.05. Conclusion: hesitancy towards COVID-19 vaccine is high among PLHIV and there is no any statistically significant association between COVID-19 vaccine hesitancy and the independent variables of the study where p-value is greater than 0.05. Hence, it is necessary to develop targeted strategies to boost vaccine uptake among this vulnerable population.

Reducing COVID-19 vaccine hesitancy and improving vaccine uptake in Nigeria

By May 30th, 2022, there were 526,182,662 confirmed COVID-19 cases and 6,286,057 deaths globally; of which Nigeria had recorded 256,028 confirmed cases and 3,143 deaths. By the same time, Nigeria had received a total of 93.9 million doses of the COVID-19 vaccine, enough to vaccinate 25% of the population however, only 27.4 million people (13.3% of the population) had received at least one dose of the vaccine. This article examines available evidence on COVID-19 vaccine hesitancy in Nigeria and makes recommendations for improving its uptake. Major causes of COVID-19 vaccine hesitancy identified in Nigeria were concerns around vaccine efficacy and safety, disbelief in the existence and severity of the disease, and distrust of the government. To reduce COVID-19 vaccine hesitancy and improve vaccine coverage in Nigeria, a mapping of vaccine acceptance and hesitancy across geographies and demographics, increased stakeholder communication, and effective community engagement are needed.

A rapid increase in coverage of COVID-19 vaccination, Central African Republic

Problem In 2021, Central African Republic was facing multiple challenges in vaccinating its population against coronavirus disease 2019 (COVID-19), including inadequate infrastructure and funding, a shortage of health workers and vaccine hesitancy among the population. Approach To increase COVID-19 vaccination coverage, the health ministry used three main approaches: (i) task shifting to train and equip existing community health workers (CHWs) to deliver COVID-19 vaccination; (ii) evidence gathering to understand people's reluctance to be vaccinated; and (iii) bundling of COVID-19 vaccination with the polio vaccination programme. Local setting Central African Republic is a fragile country with almost two thirds of its population in need of humanitarian assistance. Despite conducting two major COVID-19 vaccination campaigns, by January 2022 only 9% (503 000 people) of the 5 570 659 general population were fully vaccinated. Relevant changes In the 6 months from February to July 2022, Central African Republic tripled its coverage of COVID-19 vaccination to 29% (1 615 492 out of 5 570 659 people) by August 2022. The integrated polio­COVID-19 campaign enabled an additional 136 040 and 218 978 people to be vaccinated in the first and second rounds respectively, at no extra cost. Evidence obtained through surveys and focus group discussions enabled the health ministry to develop communication strategies to dispel vaccine hesitancy and misconceptions. Lessons learnt Task shifting COVID-19 vaccination to CHWs can be an efficient solution for rapid scaling-up of vaccination campaigns. Building trust with the community is also important for addressing complex health issues such as vaccine hesitancy. Collaborative efforts are necessary to provide access to COVID-19 vaccines for high-risk and vulnerable populations.

COVID-19 Vaccine Hesitancy and its Reasons in Addis Ababa, Ethiopia: A Cross-Sectional Study

BACKGROUND: Coronavirus disease (COVID-19) vaccine hesitancy becomes the major bottleneck to the global healthcare system in minimizing the spread of the virus. This study aimed at assessing COVID-19 vaccine hesitancy and its reasons among residents of Addis Ababa, Ethiopia. METHODS: A community-based cross-sectional survey was conducted between May 16 to 29, 2021 in purposively selected four districts of Addis Ababa, Ethiopia. A structured questionnaire was developed and then designed on Google Forms platforms to collect data from study participants after obtaining a verbal consent form. A total of 422 study participants were included in the survey. Data were entered into Microsoft Excel and then exported to the Statistical Package for the Social Sciences (SPSS) version 25 for analysis. RESULTS: Face masks and alcohol hand rub/ sanitizer are used by 50. 7 and 24.9% of respondents when required. COVID-19 was thought to have been generated by humans by a substantial percentage of study participants (38.2%). About half (50.7%) and 24.9% of respondents use face masks and alcohol hand rub/sanitizer always when it is required, respectively. A large number of study participants (38.2%) believed that origin of COVID-19 is man-made. Overall, 242 (57.4%) of study participants reported COVID-19 vaccine hesitancy. Fear of vaccine side effects (49.6%) was the most common reason for hesitancy. Doubt about its effectiveness (33.9%), not having enough information about the COVID-19 vaccine, preferring another way of protection, and unreliable of the vaccine (due to its short development period) were also the most frequently mentioned reasons for not receiving the COVID-19 vaccine. CONCLUSIONS: COVID-19 vaccine hesitancy rate was high in Addis Ababa, Ethiopia during the study period. Fear of side effects, doubts about its effectiveness, and not having enough information about the COVID-19 vaccine were major reasons for hesitancy. Continuous awareness creation to the community on the importance of vaccination is warranted by health professionals and healthcare cadres.

Is social media promoting covid-19 vaccine uptake? A case of hausa language youtube videos

The importance of social media in spreading health information, COVID-19 inclusive cannot be over emphasized and YouTube as one of the social media platforms is the most popular video-sharing platform widely. Studies in other languages showed that, videos on YouTube spread misinformation about COVID-19 vaccine. Objective: To assess the nature of information in Hausa language YouTube videos on COVID-19 vaccine uptake.Materials and Methods: This was a cross-sectional descriptive study of Hausa language YouTube videos on COVID-19 vaccine uptake. A filtered search was conducted on YouTube on 19th September, 2021 using the Hausa words for Coronavirus Vaccine as search terms. The words used were "Allurar Rigakafin Coronavirus" and "Rigakafin coronavirus". Fifty-five videos were included, YouTube video information were collected and video source and video metrics categorization were also collected. The videos were assessed to determine if they were pro-vaccination and for content, by extracting data based on information on COVID-19 vaccination contained in the videos using a predesigned proforma. Data analysis was done using Microsoft Excel 2016 and SPSS version 20. Results: About 65% of the videos had views of 0-100 with no dislike and were uploaded in the last 6 months. Only about onethird (36.4%) of the videos were pro-vaccination. Factual information on COVID-19 vaccine and information on vaccine safety, efficacy, side effects and dangers of vaccine rejection were contained in 36.4% or less of the videos. Outright misinformation was contained in as much as 25.5% of the videos. Conclusion: Most of the Hausa language YouTube videos on COVID-19 vaccine uptake were not pro-vaccination, they were not sufficiently informative on COVID-19 and some contained misinformation. Such videos with questionable content should be deleted from YouTube to forestall misleading the populace

Determinants of COVID-19 vaccine acceptance and hesitancy among healthcare professionals in the Kintampo North Municipality, Bono East Region, Ghana

tives: To assess the determinants of COVID-19 vaccine acceptance and hesitation among Health Care Professionals (HCPs) in the Kintampo North Municipality of Ghana. Design: An analytical cross-sectional study. Setting: The study was carried out in the Kintampo North Municipality. Participants: All health care professionals within the Kintampo North Municipality of Ghana. Main outcome measure: Acceptance of COVID-19 vaccine. Results: In all, 215 HCPs were included in this study. The overall vaccine acceptance was 78.6% among HCPs, while 21.4% were hesitant to receive the COVID-19 vaccine. Majority (57.7%) of HCPs believed that COVID-19 vaccines were safe. The following factors were found to influence vaccine acceptance significantly; those who knew someone who has taken the vaccine (adjusted Odds Ratio [aOR]; 14.9, 95% Confidence Interval [95% CI];5.0-45.0, p<0.001), those who think COVID -19 vaccine in Ghana was safe (AOR;9.2, 95%CI;3.3-25.8, P<0.001), those who said vaccines are effective in controlling COVID-19 transmission (aOR=5.0, 95%CI;2.1-12.4, p<0.001), and those who have never refused vaccines in the past (aOR=7.8, 95CI;1.6-37.8, p=0.01). Conclusion: The study indicated high COVID-19 vaccination acceptability among HCPs. However, some HCPs are hesitant to take COVID-19 vaccinations immediately. Increased adoption of COVID-19 vaccinations among HCPs and the broader Ghanaian population requires concerted efforts, including strengthening public health education on the perceived risks and safety of COVID-19 vaccines
