Common side effects
Like all medicines, you might experience some mild side effects 1—2 days after getting your vaccination. This is common, and a sign that your body is learning to fight the virus.
Most side effects do not last long, and will not stop you from having a second dose or going about your daily life. Some side effects may temporarily affect your ability to drive or use machinery.
The most common reported reactions are:
- pain or swelling at the injection site
- feeling tired or fatigued
- muscle aches
- joint pain
- redness at the injection site
Some side effects are more common after the second dose.
For information about uncommon and rare side effects, including myocarditis, visit the Ministry of Health website.
If you feel uncomfortable
- place a cold, wet cloth or ice pack on the injection site for a short time
- rest and drink plenty of fluids
- take paracetamol or ibuprofen.
When to seek help
If you have concerns or feel unwell after your vaccination, speak with your doctor or other health professional, or call Healthline on 0800 358 5453.
If you are concerned about your safety, call 111. Tell them you have had a COVID-19 vaccination so they can assess you properly.
If you have had a severe or immediate allergic reaction to any vaccine or injection in the past, tell your vaccinator when you arrive.
Serious allergic reactions do happen but are extremely rare.
If you have a reaction when getting the vaccine, a health worker will be there to look after you and make sure you are okay.
Reporting side effects
The Centre for Adverse Reactions Monitoring (CARM) is a database of information about adverse reactions (side effects) to medicines and vaccines in New Zealand.
CARM monitors this information to identify any issues to help with the safe use and prescribing of medicines.
Reporting your side effects will contribute to the data being collected globally, and help identify patterns in New Zealand and any potential safety issues.
