Are there side effects following vaccination?

Last update: 06/12/2021

Like all medicines, vaccines can cause side effects, but they do not occur in everyone.

The following side effects have been observed in some people: redness around the injection site, fatigue, headache, and to a lesser extent chills, aches and pains, and even fever or allergic reactions.

In rare cases, a more severe reaction may also occur. The risk of serious or long-lasting side effects is very low, but can never be excluded. This applies not only to COVID-19 vaccines, but also to any medicine, including any vaccine.

It is best to report suspected adverse reactions to the health professional who vaccinated you or, if you have been vaccinated, to the National Vaccination Centre or a mobile vaccination team by telephone on or or by e-mail to .
