What did you want to address in this study and why?
We wanted to better understand the long-term immune responses against SARS-CoV-2 in the population, and how they were influenced by the COVID-19 vaccination campaigns and the emergence of new SARS-CoV-2 variants. We studied a small German community over 31 months, which had experienced a large COVID-19 outbreak during the early pandemic in Germany.
What have we learnt from this study?
We estimated the rate at which immunity against the virus fades in the population. Our study also demonstrated the consequences of SARS-CoV-2´s changeability, by showing that neither three vaccinations nor infections with earlier variants, or a combination of both, protects from infection with the more recent Omicron variants of the virus.
