Why Vaccinate Against COVID-19? A Population-Based Survey in Switzerland

Relationship Between the Online Health Information Search and Vaccination Behavior During the COVID-19 Pandemic

Objectives

During the COVID-19 pandemic, online health information search has been shown to influence the public's health beliefs, risk attitudes, and vaccination behavior. This study constructs a conditional process model to explore how online health information search impacts public vaccination behavior, considering critical factors like healthcare system satisfaction, vaccine risk perception, and the perceived usefulness of information.

Methods

Data from the 2021 Chinese General Social Survey (N = 2,547) were analysed. The study utilized logistic regression, path analysis, and the Bootstrap method to test the conditional process model.

Results

Increased online health information search promotes vaccination behavior, while increased vaccine risk perception hinders vaccination behavior. Higher satisfaction with the healthcare system encourages vaccination behavior, but online health information search reduces healthcare system satisfaction. Satisfaction with the healthcare system and vaccine risk perception play a chain mediating role between online health information search and vaccination behavior. Additionally, the perceived usefulness of information has a negative moderating effect on online health information search and healthcare system satisfaction.

Conclusion

The research findings provide new insights for health information dissemination and vaccination interventions.

A qualitative assessment of the adverse effects associated with COVID-19 vaccines: a study from Jordan

OBJECTIVES

The current study aimed to qualitatively explore the side effects reported by participants who received the COVID-19 vaccine among the Jordanian population.

METHODS

Between April 18th and May 12th, 2022, an in-depth interview was conducted with a purposive sample of vaccinated individuals to assess the side effects of the COVID-19 vaccine in this study. Thematic analysis was used to identify themes and sub-themes within the current qualitative data.

RESULTS

A total of 20 participants were interviewed. They had a mean age of 41.3 (SD = 14.3) years. Half of the participants were females (n = 10, 50.0%). The study revealed six main themes: first, most of the respondents believed that COVID-19 vaccines were safe. Second, the vaccines are not equivalent in their safety. The third there showed that participants follow preventive measures to decrease the possibility of experiencing side effects. The fourth theme showed that reporting of side effects by the participants is dependent on the experienced side effects. Moreover, the next theme revealed that participants showed hesitancy to take more than one type of vaccine. Finally, participants were willing to take the vaccine annually, because they believed that the vaccine is better than the disease itself and decreases the aggressive effects of the disease.

CONCLUSIONS

This study found that the majority of participants believed in the safety of the COVID-19 vaccines and emphasized the responsibility of the healthcare providers in increasing awareness among the population about the importance of the vaccines. Enhancing such awareness is essential to improve the acceptance of receiving different types of vaccines.

Factors Associated With COVID-19 Non-Vaccination in Switzerland: A Nationwide Study

Objectives: We compared socio-demographic characteristics, health-related variables, vaccination-related beliefs and attitudes, vaccination acceptance, and personality traits of individuals who vaccinated against COVID-19 and who did not vaccinate by December 2021. Methods: This cross-sectional study used data of 10,642 adult participants from the Corona Immunitas eCohort, an age-stratified random sample of the population of several cantons in Switzerland. We used multivariable logistic regression models to explore associations of vaccination status with socio-demographic, health, and behavioral factors. Results: Non-vaccinated individuals represented 12.4% of the sample. Compared to vaccinated individuals, non-vaccinated individuals were more likely to be younger, healthier, employed, have lower income, not worried about their health, have previously tested positive for SARS-CoV-2 infection, express lower vaccination acceptance, and/or report higher conscientiousness. Among non-vaccinated individuals, 19.9% and 21.3% had low confidence in the safety and effectiveness of SARS-CoV-2 vaccine, respectively. However, 29.1% and 26.7% of individuals with concerns about vaccine effectiveness and side effects at baseline, respectively vaccinated during the study period. Conclusion: In addition to known socio-demographic and health-related factors, non-vaccination was associated with concerns regarding vaccine safety and effectiveness.

Adolescent Distress: Is There a Vaccine? Social and Cultural Considerations during the COVID-19 Pandemic

The COVID-19 pandemic had an unprecedented impact on mental health. In particular, the impact on adolescents was likely significant due to vulnerability factors linked to this developmental stage and pre-existing conditions of hardship. The present work aimed at grasping the particular effects of the pandemic on social and cultural aspects of adolescence, providing a cross-sectional picture of this historical moment of contemporary youth culture. Further research is needed to verify the findings.

Decision-making on COVID-19 vaccination: A qualitative study among health care and social workers caring for vulnerable individuals

In January 2021, the Swiss government introduced the first COVID-19 vaccines and prioritized allocation to at-risk individuals and professionals working with them. Despite this opportunity, vaccine uptake among staff employed in retirement homes and institutes for people with disabilities was suboptimal. This study aimed to capture real-time decision-making about COVID-19 vaccine among staff employed in nursing homes and institutes for people with disabilities in Southern Switzerland. We conducted semi-structured phone-interviews with 25 staff employed in retirement homes and institutes for people with disabilities between February and May 2021, i.e., when participants had to decide whether they wanted to adhere to the priority vaccination programme. Among participants, 21 either signed up for the COVID-19 vaccination or were fully or partly vaccinated at the time of the interview. For most participants, the vaccination choice was a challenging process: information appeared to be lacking and conflicting; numerous moral principles were at stake and contradictory; the way vaccination was organized clashed with the health values to which respondents had been previously exposed; finally, the fear of discrimination for those who decided not to get vaccinated loomed over the vaccination choice. Participants decided for or against vaccination based on principles, traditions, emotions, and a reflexive assessment of the personal vs. collective benefit of the vaccination, the latter being the most common within the investigated sample. This study shows that deciding to get vaccinated against COVID-19 is a nuanced process and that individuals cannot simply be categorized as "novax" or "provax" based on their vaccination decision.

Determinants of COVID-19 Vaccine Hesitancy During the Pandemic: A Cross-Sectional Survey in the Canton of Vaud, Switzerland

Objectives: COVID-19 vaccine hesitancy is a major obstacle in the fight against the pandemic. This study aimed to identify the local determinants of vaccine hesitancy in the context of COVID-19 to better inform future immunization campaigns. Methods: The study, conducted in February 2021, included 1,189 randomly selected inhabitants of the canton of Vaud, Switzerland. Online questionnaires investigated determinants of the intention to vaccinate. Previously validated scores (Cronbach's alphas >0.70) were applied to our data for inclusion in the ordinal logistic regression model. Results: Individuals were more likely to vaccinate if they were 40 years or older, wealthy, reported a high educational attainment, or reported comorbidities. Doubts regarding vaccine safety and efficacy, mistrust in authorities and a propensity for natural immunity were identified as the main local hindrances to the COVID-19 vaccination. Conclusion: Outreach to people at risk of severe COVID-19 is particularly relevant in the pandemic context to help mitigate vaccine hesitancy in the canton of Vaud, and should take into consideration the level of education. Further investigation is needed to better understand reasons for mistrust in authorities.
