English Corona Immunitas Nestlé is a longitudinal study conducted among employees at two Swiss sites of the company Nestlé, i.e., Nestlé Research in the canton of Vaud and Nespresso factory Romont in the canton of Fribourg. This report describes the baseline results of the study aiming at estimating the proportion of employees who have been infected with the SARS-CoV-2 and have developed antibodies at the time of the decline of the second wave until February 2021. The study has been initiated by the Institute of Family Medicine (IMF) and the Population Health Laboratory (#PopHealthLab) of the University of Fribourg within the framework of the national Corona Immunitas research program of the Swiss School of Public Health (SSPH+). The study is funded by Nestlé Research. Around 1300 employees have been invited to participate and 425 (33%) accepted to be part of the study (70% Nestlé Research and 30% Nespresso factory Romont; 52% women; age range between 21 and 64 years old with a mean of 42 years). Participants completed a questionnaire and took a blood test to measure IgA and IgG antibodies against SARS-CoV-2. Study visits were carried out by trained Nestlé medical staff on work sites between December 8, 2020 and February 11, 2021. The proportion of individuals with antibodies, both work sites combined, was 17% (95% confidence interval (CI) 13% to 22%). The proportion was 17% (95% CI 12% to 22%) among employees working on Nestlé Research sites and 18% (95% CI 12% to 26%) among those working at the Nespresso factory in Romont. The second part of this study will be conducted in spring 2021 to assess the presence of antibodies among the same participants.
