Today’s vaccines are well tolerated. Around a third of those vaccinated experience only redness or minor swelling around the injection site. This is a harmless reaction and shows that the body is reacting to the vaccine. Occasionally, in the first three days after the vaccination, general symptoms such as an increase in temperature or tiredness may occur, although these usually subside after one to three days. There are isolated instances of side effects such as headaches, body aches, nausea or allergic reactions being reported.
Today’s vaccinations are monitored extremely closely, and the chances of complications are very rare. Barely any vaccines now contain chicken protein; however, please speak to your doctor if you are aware of an allergy to this protein. Generally speaking, people with allergies should no longer have any issues with the vaccines available today.
