Hesitation regarding the COVID-19 vaccine among medical students in Brazil

The survey of vaccination hesitancy among the residents in Jinan

INTRODUCTION

Vaccination is an important way to prevent disease, but vaccine hesitancy will impact vaccine coverage and indirectly affect health. This study aims to survey the status of vaccine hesitancy among adults in Jinan.

METHODS

A cross-sectional study was conducted using the vaccine hesitancy scale among the parents of children and teenagers at hospitals in Jinan, China. We described the attitude of the parents to the vaccination through the dimensions of confidence (items: L1-L7) and the risk (items:L8-L10).The participants will be regarded as lacking confidence if the score is over 21 among the items (L1-L7), and participants will consider the vaccination to be a "Risk" if the score is over 9 among the items (L8-L10). Using the chi-square test to analyse the differences of attitude between different participants.

RESULTS

202 individuals were enrolled, and most respondents (88.70%) agreed that vaccines are important for their child's health. 33.50% agreed and strongly agreed that new vaccines carried more risks than older vaccines. The average score for the lack of confidence in the vaccination was 11±0.25. The average score for risk for vaccination was 9.92±0.04. Participants aged below 30 years, females, those with lower education, and those without medical workers in the family were more concerned about the risks of vaccines.

CONCLUSIONS

Participants were confident about the vaccination. But they were also concerned about the risks of vaccines. A lack of vaccine knowledge may led the participants to have hesitancy about vaccinations.

Overview of childhood vaccination coverage in Brazil and the impact of the COVID-19 pandemic: Is our children's health at risk? A review of pre-COVID-19 periods and during the COVID-19 pandemic

Introduction

The coronavirus disease (COVID)-19 has had a great impact on several aspects related to the population's health, including the vaccination adherence rate. This study describes how childhood vaccination coverage (CVC) in Brazil was affected by the pandemic in the period from 2020 to 2022 and explores the relationship between this data and the Human Development Index (HDI), and the number of votes received in the government with a right-wing political ideology.

Methods

An ecological analysis of CVC was carried out including 12 vaccines. The HDI was evaluated considering the HDI-General, HDI-Income, HDI-Longevity, and HDI-Education. The percentage of valid votes received by the former president (right-wing political ideology) was also obtained. Spearman correlation tests were applied to compare markers.

Results

During the period analyzed, it was observed a linear growth trend in CVC between 2015 and 2018 regarding all vaccines. However, from 2018 onwards, after the presidential elections in Brazil, the CVC reduced significantly, showing an even more pronounced decrease with the start of the COVID-19 pandemic. This reduction in CVC observed for some vaccines was related to the higher percentage of votes for the government with a right-wing political ideology, especially in relation to the BCG (bacillus Calmette and Guerin) and pentavalent (protecting against diphtheria, tetanus, pertussis, hepatitis B, and Haemophilus influenzae type b bacteria) vaccines. In addition, when analyzing the HDI, it was observed that the lowest values of this indicator were associated with a more expressive reduction in CVC, mainly related to yellow fever, pentavalent, 10-valent pneumococcal conjugate, Human rotavirus, and triple viral (protecting against measles, mumps, and rubella - MMR) vaccines.

Conclusion

Although Brazil has a successful and exemplary record in combating several diseases, mainly due to the high rate of CVC, the continuous reduction in this coverage must be thoroughly evaluated by health managers.

Novel COVID-19 vaccine hesitancy and acceptance, and associated factors, amongst medical students: a scoping review

Medical students are likely to be exposed to COVID-19 patients so achieving high vaccination coverage rates for this group of healthcare workers is important, as is their potential as vaccination role models. The aim of this scoping review was to evaluate the current literature to determine the rates of COVID-19 vaccine hesitancy and acceptance, and associated factors, amongst medical students. Systematic searches of the Medline Ovid, Embase, PubMed, and Education Resources Information Centre (ERIC) online databases was conducted for relevant articles with keywords: 'COVID-19', 'vaccine hesitancy & acceptance' and 'medical students'. Articles were included for review if they reported the rates of vaccine hesitancy and acceptance, and associated factors, amongst medical students. Of the 258 articles identified, 52 met the inclusion criteria and underwent full-text review. Rates of vaccine hesitancy ranged from 5.4-86.7%, with generally positive attitudes towards COVID-19 vaccination. The main factors associated with vaccine hesitancy were concerns about the safety and efficacy of vaccines due to their accelerated development, being a pre-clinical medical student, and low perceived personal risk of COVID-19 infection. Inconsistencies were found for the influence of gender on attitudes towards vaccinations. Previous vaccination behaviours were predictive of willingness to receive the COVID-19 vaccine. Knowledge about COVID-19 vaccinations and their importance was found to be deficient amongst vaccine hesitant medical students. Generally, medical students express low levels of vaccine hesitancy. However, due to the variability in the factors associated with vaccine hesitancy across different populations and the dynamic and contextual nature of hesitancy, it is recommended that vaccination intent and associated attitudes are monitored on a longitudinal basis. It is important to map vaccine hesitancy at a local level to allow medical schools to develop strategies to encourage vaccination specific to their school's needs.

COVID-19 vaccine hesitancy in Latin America and Africa: a scoping review

Vaccination has played an important role in the containment of COVID-19 pandemic advances. However, SARS-CoV-2 vaccine hesitancy has caused a global concern. This scoping review aims to map the scientific literature on COVID-19 vaccine hesitancy in Latin America and Africa from a Global Health perspective, observing the particularities of the Global South and using parameters validated by the World Health Organization (WHO). The review reporting observes the recommendations of the PRISMA for Scoping Reviews (PRISMA-ScR) model. Search was conducted in PubMed, Scopus, Web of Science, and Virtual Health Library (VHL) databases, selecting studies published from January 1, 2020 to January 22, 2022. Selected studies indicate that COVID-19 vaccine hesitancy involves factors such as political scenario, spread of misinformation, regional differences in each territory regarding Internet access, lack of access to information, history of vaccination resistance, lack of information about the disease and the vaccine, concern about adverse events, and vaccine efficacy and safety. Regarding the use of conceptual and methodology references from the WHO for vaccine hesitancy, few studies (6/94) use research instruments based on these references. Then, the replication in Global South of conceptual and methodological parameters developed by experts from the Global North contexts has been criticized from the perspective of Global Health because of it may not consider political and sociocultural particularities, the different nuances of vaccine hesitancy, and issues of access to vaccines.

COVID-19 vaccination intention among nursing, medical, and dental students: A systematic review and meta-regression analysis

The introduction of the COVID-19 vaccine amidst the pandemic has heralded a paradigm shift. Healthcare students in nursing, medicine, and dentistry must have positive attitudes owing to their future role in vaccine recommendations to the public and patients. This meta-regression analysis assessed the differences in COVID-19 vaccination intention (VI) of nursing, medical, and dental students. Medline/PubMed, EMBASE, CINAHL, Cochrane Library, and Korean MBASE were searched for eligible studies. Quality was assessed by the Joanna Briggs Institute's quality appraisal. Forty-one studies were included in the final analysis, and the estimation of pooled prevalence (68%) and relevant factors were assessed. Dental students were found to have the lowest VI (57%), which significantly (p = .018) differed from that of nursing students (64%). Countries in South-East Asia and those with high income levels were found to have high VI. Therefore, global vaccine programs for healthcare students should be prepared considering their geographical and economic status.

COVID-19 Vaccine Acceptance Rate and Its Factors among Healthcare Students: A Systematic Review with Meta-Analysis

Healthcare students are clinicians-in-training likely to come into contact with COVID-19 as much as other frontline healthcare professionals. It is therefore necessary to prioritize vaccinations for this group. We conducted a global systematic assessment of COVID-19 vaccine acceptance rates and related factors among healthcare students using the PubMed, Scopus, and Web of Science databases and keyword searches in March of 2022. We found 1779 articles with relevant information and 31 articles that matched our inclusion criteria. We performed a random-effects meta-analysis and quality assessment using the eight-item Joanna Briggs Institute Critical Appraisal test for cross-sectional studies. A total of 30,272 individuals from 16 countries were studied. Most of the studies were carried out in the U.S. (n = 6), China (n = 5), Poland (n = 5), India (n = 2), Italy (n = 2), and Israel (n = 2). The prevalence of the COVID-19 vaccine acceptance rate was 68.8% (95% confidence interval [CI]: 60.8-76.3, I2 = 100%), and the prevalence of the vaccine hesitancy rate was 25.8% (95% CI: 18.5-33.8, I2 = 99%). In country-specific analyses, Romania showed the highest acceptance rate (88.0%, 95% CI: 44.5-100%), while Iraq showed the lowest acceptance rate (66.2%, 95% CI: 35.5-90.8%). In time-trend analyses, we found that acceptance rates among healthcare students decreased over time. Students concerned about potentially serious side effects of the vaccine were less willing to accept the vaccine. National and international interventions should be adopted to reduce COVID-19 vaccination hesitancy rates among these important frontline workers.
