Your contribution makes vaccination even safer.

Why do this study?

The coronavirus (COVID-19) vaccines have been researched thoroughly before being given to the public. Only by being well researched may they be used. However, side effects after vaccination are always a possibility. The Drug Safety Research Unit would like to monitor this information. By doing so we will learn more about possible side effects as quickly as possible.

Some people experience a side effect after receiving the COVID-19 vaccine. The DSRU is collecting information on possible side effects (adverse events) after vaccination with COVID-19 vaccines and we would like you to participate, even if you do not experience any. Register within two days of your first -COVID-19 vaccination, or if you will receive one soon.

Keep your vaccination card with the vaccine name and batch number of your vaccination. This information may be important when participating in this study.

What does participation mean?

After registering for the study, you will receive the first questionnaire. Seven days after vaccination, you will receive the next questionnaire. In total you will receive seven questionnaires over a period of six months. Questionnaires need to be filled in electronically via the web app. Each questionnaire takes 10-25 minutes to complete. The questions are about the possible side effects that you may have experienced after vaccination. Even if you do not experience any side effects, we ask that you still complete the questionnaires. Participation is completely voluntary. You can stop your participation at any time without explanation.

What happens with my data?

Your data is stored securely in accordance with the General Data Protection Regulation. More information can be found in the <DSRU privacy statement>.

What complaints can I expect?

After any vaccination, a reaction can happen at the site of injection. It can be painful, red and/or swollen. You may feel generally unwell for a few days after the vaccination. Side effects such as headache, fever and muscle ache can also occur.
