Abstract

Abstract: Vaccination is considered the best measure to overcome the Sars-Cov2 pandemic. However, changing national recommendations on sequence and time frame necessitate the collection of real-word data on adverse events of Sars-CoV2 vaccination protocols outside of pivotal trials. We report results from a survey on the adverse events and the operational consequences of a Sars-CoV2 vaccination campaign with partly mixed vaccination protocol as well as booster vaccination. While the spectrum of adverse effects in our cohort appeared to be similar to pivotal studies, there were substantial differences in both frequency and distribution with only 3 out of 10 participants staying symptom-free. In over 26% of vaccinees symptoms were so severe, that they stayed at home with mean days on sick leave being 1.5 per person using mixed vaccination protocol. Being aware, that these results might partially be attributable to nocebo effects they are of importance for future vaccination campaigns.
