Survey of Symptoms After a COVID Vaccination in Employees: a Retrospective Study.

Background:

SARS-CoV-2 (Severe acute respiratory syndrome coronavirus type 2) has had us firmly in its grip for more than two years. In January 2021, the quality and risk management unit of the LKH (Landeskrankenhaus) -Univ. Klinikum Graz commissioned to carry out vaccinations for employees and subsequently for high-risk patients.

In the vaccination line, which was open for 85 days in 2021/22, the vaccines from Astra Zeneca, Biontech-Pfizer and Moderna were vaccinated. There were hardly any complications. The primary immunization, booster vaccination and booster vaccination were carried out.

Despite the small number of incidents in the sense of an immediate reaction, there were numerous sick leave.

Methods:

For this reason, in the course of the booster vaccination, starting from October 2021 to January 2022, every vaccinated person was asked to fill out a questionnaire. Participation was voluntary and was supported by the works councils of the Medical University and the LKH-University clinic Graz approved. The survey served to retrospectively record how many employees developed symptoms in response to the respective vaccination.

With this approach it will be possible to subject the responses to an in-depth statistical analysis in order to obtain a data-based contribution to the side effects of vaccines categorized with different vaccination schemes.
