To reduce the spread of COVID-19, schools closed and moved to remote learning in many countries and municipalities. At the time of this study, Switzerland maintained the position that schools should be prioritized to remain open. The state of knowledge regarding the challenges that school staff encountered during the pandemic was limited. The aim of this study was to qualitatively explore the impact of COVID-19 and related measures in Switzerland on the professional life of school staff in terms of challenges, strategies, and benefits. Data were collected between November 2021 and March 2022. We conducted interviews with 47 participants working in nurseries, kindergartens, primary, middle, special, and after-schools across Switzerland. The majority were women and part of the teaching staff. Most had received at least one dose of the COVID-19 vaccine. Participants reported various challenges such as isolation, loneliness, and 'dryness' of work, pedagogical alienation and deontological distress, privacy loss, and confusion regarding health measures. They also cited different strategies, namely resuming simple activities, finding the right degree of transgression, recreating normality with children, and continuous adaptation. Finally, they identified some benefits, i.e. improvements in education regarding hygiene standards, greater acceptance of illness and death as a normal part of life, recognition of the privilege of being able to attend school in-person, and valorization of cultural diversity. We highlight the importance of listening to staff's concerns, enacted strategies, and perceived benefits and taking them into account when developing appropriate and effective public health and communication efforts., (© The Author(s) 2024.

Objectives: The COVID-19 pandemic continues, and evidence on infection- and vaccine-induced immunity is key. We assessed COVID-19 immunity and the neutralizing antibody response to virus variants across age groups in the Swiss population., Study Design: We conducted a cohort study in representative community-dwelling residents aged five years or older in southern Switzerland (total population 353,343), and we collected blood samples in July 2020 (in adults only, N = 646), November-December 2020 (N = 1457), and June-July 2021 (N = 885)., Methods: We used a previously validated Luminex assay to measure antibodies targeting the spike (S) and the nucleocapsid (N) proteins of the virus and a high-throughput cell-free neutralization assay optimized for multiple spike protein variants. We calculated seroprevalence with a Bayesian logistic regression model accounting for the population's sociodemographic structure and the test performance, and we compared the neutralizing activity between vaccinated and convalescent participants across virus variants., Results: The overall seroprevalence was 7.8% (95% CI: 5.4-10.4) by July 2020 and 20.2% (16.4-24.4) by December 2020. By July 2021, the overall seroprevalence increased substantially to 72.5% (69.1-76.4), with the highest estimates of 95.6% (92.8-97.8) among older adults, who developed up to 10.3 more antibodies via vaccination than after infection compared to 3.7 times more in adults. The neutralizing activity was significantly higher for vaccine-induced than infection-induced antibodies for all virus variants (all p values < 0.037)., Conclusions: Vaccination chiefly contributed to the reduction in immunonaive individuals, particularly those in older age groups. Our findings on the greater neutralizing activity of vaccine-induced antibodies than infection-induced antibodies are greatly informative for future vaccination campaigns.

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., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: L.
