In addition to the antibody status, Corona Immunitas studies collect data on vaccination intensions and vaccination status of participants since February 2021. The vaccine questions are standardized across cantons and queried every four weeks.

The subsequent graphs show the vaccination status per language region in monthly assessment waves. Each assessment wave lasted for one week and the first assessments were made in the second half of February.

The vaccination status is defined as not vaccinated or vaccinated (received at least one vaccine injection for SARS-CoV-2).

Please note that the age structure of Corona Immunitas participants does not reflect the one of the Swiss population and participants are likely to better adhere to guidance and recommendations in dealing with the COVID-19 pandemic. Thus, the figures are probably higher than those for the Swiss population as a whole. 

Vaccination Status Stratified by Age

Vaccination status stratified by age, language region and assessment wave. Individuals who have received at least one dose of vaccine were considered vaccinated.

Likeliness to Get Vaccinated or Already Vaccinated

This plot combines the information of persons who have been vaccinated (at least once) and the likeliness to get vaccinated in those, who have not been vaccinated yet, grouped into three categories,
Very unlikely / Rather unlikely, Unsure and Rather likely / Very likely.

Vaccination status or likeliness of vaccination, stratified by age, assessment wave and sex - relative representation. Individuals who have received at least one dose of vaccine were considered vaccinated.
