What if I have a reaction to the vaccine?
You may experience some side effects after receiving a COVID-19 vaccination, like soreness or redness where you received your needle, mild fever or headache. Some people may experience more significant flu-like symptoms. Most side effects last no more than a couple of days.
Serious reactions such as allergic reactions are rare. They usually occur within 15 minutes of receiving a vaccine, which is why you are asked to wait for this time period after receiving your vaccination.
Use the COVID-19 vaccine side effects symptom checker if you have concerns about any symptoms after your vaccine. The checker is also available through the National Coronavirus Helpline, 1800 020 080, 24 hours a day.
