Over what period following vaccination can adverse vaccination reactions occur?

Most side effects occur shortly after vaccination. As a rule, they are mild and last only a short time. Similar to the side effects of other vaccinations, these are mostly reactions at the injection site (pain in particular, but also redness and swelling) or general symptoms (such as fatigue, headache, aching muscles and joints or fever). Side effects are possible for six months after vaccination.

Contact your doctor if the side effects last for a longer period or get worse, or if there is a change in your wellbeing in the weeks after the vaccination.
