Like all medicines, vaccines can cause side effects. Most are mild or moderate, tend to be less common in older people, and go away within a few days. If side effects such as pain and/or fever are troublesome, they can be treated by medicines for pain and fever such as paracetamol.
Common side effects: These may affect more than 1 in 10 people
- Having a painful, heavy feeling and tenderness in the arm where you had your injection. This tends to be worst around 1-2 days after the vaccine.
- Feeling tired.
- Having a headache.
- General aches, or mild flu like symptoms.
Although feeling feverish is not uncommon for two to three days, a high temperature is unusual.
