The Psychometric Properties of Intention to Receive the COVID-19 Vaccine Scale Based on the Health Belief Model.

Acceptance of the SARS-CoV-2) COVID-19( vaccine is a very important factor to keep health workers safe. The study aimed to evaluate the psychometric properties of intention to receive the COVID-19 vaccine using a health belief model among health workers in Iran The study was a tools design study that was conducted in the period from February to March 2020, Iran Questionnaire items were designed using text review. The sampling method was multi-stage. Data were analyzed using descriptive statistics, confirmatory and exploratory factor analysis at a 95% confidence level using SPSS software version 16. The designed questionnaire had an appropriate content validity and internal consistency. Also, the exploratory factor analysis showed that a 5-factor structure was extracted and confirmatory factor analyses revealed that the conceptual five-factor structure of the measure had good fit indices. Reliability was evaluated using internal consistency. Cronbach Alpha coefficient was .82 and the intra-class correlation coefficient (ICC) was .9. It can be concluded that the instrument designed in the preliminary stage of psychometrics properties had good validity and reliability indicators. Also, the constructs of the health belief model well explain the determinants of the intention to receive the COVID-19 vaccine at the individual level.

Effectiveness of different vaccine platforms in reducing mortality and length of ICU stay in severe and critical cases of COVID-19 in the Omicron variant era: A national cohort study in Iran.

Various severe acute respiratory syndrome coronavirus 2 vaccines with different platforms have been administered worldwide; however, their effectiveness in critical cases of COVID-19 has remained a concern. In this national cohort study, 24 016 intensive care unit (ICU) coronavirus disease-2019 (COVID-19) admissions were included from January to April 2022. The mortality and length of ICU stay were compared between the vaccinated and unvaccinated patients. A total of 9428 (39.25%) patients were unvaccinated, and 14 588 (60.75%) patients had received at least one dose of the vaccine. Compared with the unvaccinated, the first, second, and third doses of vaccine resulted in 8%, 20%, and 33% lower risk of ICU mortality in the adjusted model, with risk ratio (RR): 0.92, 95% confidence interval (CI): 0.84-1.001, RR: 0.80, 95% CI: 0.77-0.83, and RR: 0.67, 95% CI: 0.64-0.71, respectively. The mean survival time was significantly shorter in the unvaccinated versus the fully vaccinated patients (hazard ratio [HR]: 0.84, 95% CI: 0.80-0.88); p < 0.001). All vaccine platforms successfully decreased the hazard of ICU death compared with the unvaccinated group. The duration of ICU stay was significantly shorter in the fully vaccinated than in unvaccinated group (MD, -0.62, 95% CI: -0.82 to -0.42; p < 0.001). Since COVID-19 vaccination in all doses and platforms has been able to reduce the risk of mortality and length of ICU-stay, universal vaccination is recommended based on vaccine availability.

Risk Communication in Early Containment of COVID-19 Pandemic in Iran: Implementation of the World Health Organization Strategic Preparedness and Response Plan (WHO-SPRP).

Background: Health systems must have functional and efficient preparedness and response plans to manage pandemics. Moreover, it is essential to adjust to changing circumstances and the dynamic character of pandemics. The World Health Organization (WHO) introduced the Strategic Preparedness and Response Plan (SPRP), emphasizing 144 measures across 10 pillars, helping governments prepare and respond to the coronavirus disease 2019 (COVID-19) pandemic. This study aimed to determine how the Iranian health system, based on the WHO-SPRP, addresses strategic preparedness and response plan in the COVID-19 pandemic at the national level. Methods: The WHO-SPRP was adopted and translated into Persian by 2 bilingual natives. The chief of the health office requested that authorized officers complete the SPRP. Then, a meeting was held by officers of related units involved in COVID-19 management to address the SPRP at regional and national levels. Results: Our findings suggest that up to August 2020, effective risk communication and community engagement were not fully established. Our response plan lacked evidence-based information and educational messaging to consistently shape public opinion and impression of a respiratory pandemic. Conclusion: The Iranian health care system and services were almost able to address the SPRP and perform the major indicators that the WHO had proposed. However, special attention should be paid to risk communication and community engagement to empower informed decision-making by individuals and communities.

Vaccine hesitancy from the parent perspectives: protocol for a qualitative study in Iran.

INTRODUCTION: WHO declared vaccine hesitancy as a global public health threat in 2019. Since even a slight reduction in vaccine coverage rates can lead to a decrease in herd immunity, it is imperative to explore the underlying factors affecting vaccine hesitancy. This qualitative study protocol aims to explore determinant factors that influence vaccine hesitancy in Iran from the parent's perspective. METHODS AND ANALYSIS: Descriptive-Interpretive Qualitative research will be conducted to gain an insight into vaccine hesitancy in the west of Tehran province in Iran. Participants in the study will be recruited from vaccine-hesitant parents of children under 5 years' old who will be recognised as being hesitant to extract from the national health information system. The semistructured interviews and in-depth questions will be performed both face-to-face in an open space such as a park near their homes and via video call because of the COVID-19 pandemic and social distancing. Interviews will be conducted by a trained qualitative person. Transcribed data will be analysed through thematic analysis. ETHICS AND DISSEMINATION: Ethics approval was obtained from the research ethics committee at the Iran University of Medical Sciences (Approval ID #IR.IUMS.REC.1399.273). The results of the study are expected to be presented by the end of 2022 year. A variety of dissemination methods will be employed to communicate research findings, including presentations at conferences and peer-reviewed publications.

Determinants of COVID-19 vaccine acceptance in healthcare workers in Iran: National Survey.

BACKGROUND AND AIM: It seems that acceptance of COVID-19 vaccination is the most effective way to tackle the COVID-19 pandemic now. Health care workers (HCWs) are one of the most important groups who are at risk for COVID-19 infection. This study aimed to assess the COVID-19 vaccine acceptance among HCWs in Iran and its determinants. METHODS: A cross-sectional survey was carried out among 3600 HCWs in Iran. Data were collected through a self-administered questionnaire by a trained team from February to March 2021. Multi-stage cluster sampling method was used for selecting respondents of the study. Multivariate logistic regression analysis was used to determine the key factors of COVID-19 vaccine acceptance among participants. P-value < 0.05 was considered statistically significant. RESULTS: Out of the 3536 respondents, 2191 (62.1%) intended to uptake the COVID-19 vaccine. Only about 10 percent of respondents said they did not trust any vaccine (domestic or foreign). Willing to accept a COVID-19 vaccine was relatively high among males, doctors, and those who had a history of hospitalization due to COVID-19 infection. The multivariate regression analysis showed respondents who were 40-50 years (aOR: 1.56; 95% CI: 1.47-1.66), had a history of COVID-19 infection (aOR: 0.85; 95% CI: 0.83-0.88), and hospitalized due to COVID-19 infection (aOR: 2.18; 95% CI: 1.97-2.39), were significantly associated with vaccine acceptance (p < 0.05). CONCLUSION: Our study showed moderate acceptance of COVID-19 vaccination in the HCWs in the Islamic Republic of Iran. The most important factor in the acceptance of the COVID-19 vaccine by the health staff is having a history of hospitalization. Further training and justification of health personnel is needed to increase the acceptance of COVID 19 vaccine.
