As with any vaccine, you may have some side effects after receiving a COVID-19 vaccine. Common reactions to COVID-19 vaccinations include:
- Pain at the injection site
Less common side effects include:
- Redness or swelling at the injection site
- Swelling or tenderness in the armpit
- Nausea / vomiting
- Enlarged lymph nodes
These side effects are usually mild and usually go away within two or three days. Some people will experience more significant flu-like symptoms from this vaccination compared to other common vaccinations and may require time away from normal activities. These symptoms may occur after either dose but are more common after the second dose.
If you experience pain at the injection site or fever, headaches or body aches after vaccination, you can take paracetamol or ibuprofen. These help to reduce some of the above symptoms. You do not need to take paracetamol or ibuprofen before vaccination. If there is swelling at the injection site, you can use a cold compress.

- Sever allergic reaction (anaphylaxis)
- Myocarditis (inflammation. of the heart muscle)
- Pericarditis (inflammation of the outer lining of the heart)
Most reported cases have been mild and recovered quickly, although longer-term follow-up of these cases is ongoing. Cases occur predominantly after the second dose and predominantly in younger males (aged <30 years).
