Acceptance of Public Health Measures During the COVID-19 Pandemic: A Cross-Sectional Study of the Swiss Population's Beliefs, Attitudes, Trust, and Information-Seeking Behavior

Objectives: This study aimed to advance the understanding of the factors associated with population acceptance of public health measures during the COVID-19 pandemic. Methods: In January 2022, we conducted a cross-sectional survey of the Swiss population (N = 2,587). Questionnaires were administered through computer-assisted web interviewing. Measures covered included information-seeking behavior, attitudes towards and beliefs about public health measures enacted, and trust in institutions. Results: Television and newspapers were the most used information sources. Those with higher education levels were more likely to use channels from public institutions, newspapers, and television. The most important criterion for reliable information was scientific evidence. Trust was highest for doctors, healthcare workers, universities, research institutes, and public health institutions. Acceptance of public health measures was high overall, and attitudes, beliefs, information-seeking behavior, and trust were positively related to acceptance. Trust in science remained stable, while trust in public health institutions decreased slightly. Conclusion: While nurturing a two-way dialogue with the population, institutions should target communication considering age and culture, improve risk communication, ground messages in scientific evidence, and ensure mass media presence.

Influenza Vaccination Behaviour of Healthcare Workers in Switzerland: A Cross-Sectional Study

Objectives: As no data are available regarding the influenza vaccination status of Swiss healthcare workers (HCW) in the ambulatory setting, this study aims to investigate their influenza vaccination behaviours.

Methods: We conducted an online survey using a four-item, semi-structured questionnaire to assess HCWs influenza vaccination coverage and behaviour. Associations between influenza vaccination status, age and language as well as recommendation behaviour and reasons for vaccination were assessed using descriptive statistics and logistic regression analyses.

Results: Of the 1057 completed questionnaires, 425 (40.2%) HCW were vaccinated and 632 (59.8%) not. 78.1% of the physicians and 47.3% pharmacists were vaccinated, compared to only 29.1% of the nurses, 24.3% pharmacy technicians and 13.0% medical practice assistants (MPA). There was a significant association between influenza vaccination status and HCW profession, age, language and how often an influenza vaccination recommendation was made.

Conclusion: Demographic factors seem to influence HCWs’ attitudes towards influenza vaccination, which in turn affects the prospect of them recommending the influenza vaccination. Diverse strategies might be necessary to encourage HCW to get vaccinated and hence, promote influenza vaccination.

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.

Vaccine hesitancy and HPV vaccine uptake among male and female youth in Switzerland: a cross-sectional study

OBJECTIVES

Identifying factors associated with human papillomavirus (HPV) vaccine uptake is essential for designing successful vaccination programmes. We aimed to examine the association between vaccine hesitancy (VH) and HPV vaccine uptake among male and female youth in Switzerland.

DESIGN

With a cross-sectional study, an interview-based questionnaire was used to collect information on sociodemographic factors, vaccination records and to measure the prevalence of VH using the Youth Attitudes about Vaccines scale (YAV-5), a modified version of the Parent Attitudes about Childhood Vaccinations survey instrument.

SETTING AND PARTICIPANTS

Eligible male and female participants, 15-26 years of age, were recruited through physicians' offices and military enlistment in all three language regions of Switzerland. Of 1001 participants, we included 674 participants with a vaccination record available (415 males and 259 females) in this study.

PRIMARY AND SECONDARY OUTCOME MEASURES

The outcome was uptake for HPV vaccine (having received ≥1 dose of HPV vaccine). Covariates were VH, sex, age and other sociodemographics.

RESULTS

151 (58%) female and 64 (15%) male participants received ≥1 dose of HPV vaccine. 81 (31%) female and 92 (22%) male participants were VH (YAV-5-Score >50). The odds for being unvaccinated were higher for VH women than non-VH women, adjusted OR=4.90 (95% CI 2.53 to 9.50), but similar among VH and non-VH men, OR=1.90 (95% CI 0.84 to 4.31). The odds for being unvaccinated were lower for younger men (born on or after 1 July 2002) than older men (born before 1 July 2002), OR=0.34 (95% CI 0.14 to 0.81), but we found no association between age and vaccine uptake for female youth, OR=0.97 (95% CI 0.48 to 1.97).

CONCLUSIONS

VH was associated with lower HPV vaccine uptake in female youth but not male youth in our study population in Switzerland. Our findings suggest that issues other than VH contribute to HPV underimmunisation in male youth in Switzerland.

HPV vaccine awareness, knowledge and information sources among youth in Switzerland: a mixed methods study

OBJECTIVES

We aimed to provide a detailed characterisation of human papillomavirus (HPV) vaccine awareness, knowledge and information sources in the HPV vaccine decision-making process of youth, both male and female, in Switzerland.

DESIGN

With a mixed-method study design, we conducted quantitative questionnaires and qualitative interviews, which lasted 20-45 min.

SETTING AND PARTICIPANTS

We recruited participants, 15-26 years of age, in physicians' offices, in a local sexual health clinic, and during military enlistment. We administered quantitative questionnaires to 997 youth participants (585 male, 412 female) and conducted qualitative interviews with 31 youth (17 male, 14 female).

PRIMARY AND SECONDARY OUTCOME MEASURES

We assessed HPV vaccine awareness, knowledge, information sources and vaccination status.

RESULTS

In the study's quantitative component, 108 (20%) male and 262 (65%) female participants had received ≥1 dose of HPV vaccine. 697 (70%) participants were knowledgeable about the HPV vaccine. Females were more likely to be knowledgeable than males (342/412 (83%) vs 355/585 (61%); p<0.01). Younger participants in the sample compared with older participants were more likely to be aware of HPV vaccine (135/148 (91%) vs 695/849 (82%); p<0.01). The three most mentioned information sources were school health programmes (442 (53%)), healthcare providers (190 (23%)) and participants' social networks (163 (20%)). Overall, 554/710 (78%) participants had a female-gendered perception of HPV vaccine, a finding which was further supported and explained by qualitative data.

CONCLUSIONS

Despite a male HPV vaccine recommendation being made >4 years prior to the data collection, HPV vaccine knowledge was higher among females than males, and a female-gendered perception of HPV vaccine remains prevalent. Internet and social media were minor HPV vaccine information sources. Study findings demonstrate that HPV knowledge matters for HPV vaccine uptake and suggest that we should improve HPV information quality and access for youth, particularly by tailoring knowledge campaigns to young men.

Attitudes Toward COVID-19 Vaccination Among Young Adults in Zurich, Switzerland, September 2020

Objectives: Young adults are essential to the effective mitigation of the novel coronavirus (SARS-CoV-2/COVID-19) given their tendency toward greater frequency of social interactions. Little is known about vaccine willingness during pandemics in European populations. This study examined young people's attitudes toward COVID-19 vaccines in Fall 2020. Methods: Data came from an ongoing longitudinal study's online COVID-19-focused supplement among young adults aged 22 in Zurich, Switzerland (N = 499) in September 2020. Logistic regressions examined young adults' likelihood of participating in COVID-19 immunization programs. Results: Approximately half of respondents reported being unlikely to get vaccinated against COVID-19. Compared to males, females were more likely to oppose COVID-19 vaccination (p < 0.05). In multivariate models, Sri Lankan maternal background and higher socioeconomic status were associated with a greater likelihood of getting vaccinated against COVID-19 (p < 0.05). Respondents were more likely to report a willingness to get vaccinated against COVID-19 when they perceived 1) an effective government response (p < 0.05) and 2) their information sources to be objective (p < 0.05). Conclusion: This study communicates aspects important to the development of targeted information campaigns to promote engagement in COVID-19 immunization efforts.

Antenatal influenza vaccination in urban Pune, India: clinician and community stakeholders' awareness, priorities, and practices

The World Health Organization (WHO) recommends antenatal influenza vaccination (AIV) for pregnant women at any stage of pregnancy. This study assessed fundamental aspects of AIV acceptance and demand among key stakeholders in urban Pune, India. Semi-structured interviews for rapid ethnographic assessment of AIV-related awareness, priorities, and practices were used to study clinicians and their communities of practice. A qualitative survey was conducted among 16 private clinicians providing antenatal care (ANC) in slum and middle-class areas of Pune. Following the survey, clinicians were informed about authoritative AIV recommendations. A qualitative community survey was also conducted with 60 women aged 20-35 years and 30 spouses from the same slum and middle-class practice areas of the ANC providers. Subsequently, a second clinician survey was conducted to assess changes in clinicians' awareness, priority, and vaccination practice. After this interview, clinicians were informed of community survey findings. Most community respondents were unaware of AIV, in contrast with well-known and widely used antenatal tetanus vaccination. They expressed confidence in vaccines and trust in the clinicians. Clinicians' advice was reportedly the most important determinant of community vaccine acceptance. Clinicians were confident of the safety of AIV and they anticipated patients' acceptance if recommended. The second clinician interview showed increased awareness of AIV policy, but clinicians were more skeptical about the severity of maternal influenza in their practice. Our findings indicate community acceptance though not demand for AIV. We recommend five essential elements for vaccination program strategies to improve coverage with AIV and other ANC vaccines.
