ABSTRACT

Background:

The aim of our study was to assess the influence of gender and age on reactogenicity by the different vaccines and their combinations. Further parameters were the reduction in working capacity after vaccination and the influence of the time of day when vaccines were administered. Methods We conducted a survey on COVID-19 vaccinations and eventual reactions among employees of 89 hospitals of the Helios Group. On May 19th, 2021 employees received an invitation by e-mail from the chief medical officer with a link to the survey tool. Participation was voluntary and non-traceable. The survey was closed on June 21st, 2021. Results 8,375 participants reported on 16,727 vaccinations. Reactogenicity was reported in 75% of COVID-19 vaccinations. In 23% the capacity to work was affected. Major risk factors were female gender, younger age and vaccine other than BNT162b2. ChAdOx induced impairing reactogenicity mainly after the prime vaccination (70.5%), while mRNA-1273 led to more pronounced reactions after the second dose (71.7%). Heterologous prime-booster vaccinations with ChAdOx followed by either mRNA-1273 or BNT162b2 were associated with the highest risk for impairment (81.4%). The time of day of the vaccinations showed no influence. Conclusions Young women had the highest chance to experience reactogenicity and to be unable to work after COVID-19 vaccination. When vaccinating a large part of a workforce, especially in professions with a higher proportion of women like health care, employers as well as employees must be prepared for a noticeable amount of absenteeism. Trial registration The study was approved by the Ethic Committee of the Aerztekammer Berlin on May 27th, 2021 (Eth-37/21) and registered in the German Clinical Trials Register (DRKS 00025745). The study was supported by the Helios research grant HCRI-ID 2021-0272.
