Common side effects are the same for all COVID-19 vaccines used in the UK, and include:
- having a painful, heavy feeling and tenderness in the arm where you had your injection. This tends to be worst around a day or two following the vaccination
- feeling tired
- general aches, or mild flu like symptoms
You can rest and take paracetamol (follow the dose advice in the packaging) to help make you feel better. Although feeling feverish is not uncommon for 2 to 3 days, a high temperature is unusual and may indicate you have COVID-19 or another infection.
Although a fever can occur within a day or two of vaccination, if you have any other COVID-19 symptoms or your fever lasts longer, stay at home. Symptoms following vaccination normally last less than a week. If your symptoms seem to get worse or if you are concerned, you can call NHS 111.
