Does vaccination have any side effects?

Basically, all vaccinations may prompt unpleasant reactions. They may include pain at the vaccine site, fatigue, headache or slight fever. This, however, is a normal response to a vaccine. It is a sign that your immune system responds and forms antibodies to protect you against the disease.

Serious and undesirable side effects after a Corona vaccination are very rare. We can be so certain because the vaccines have been given to billions of people worldwide, and any serious side effects must always be reported.
