Millions of children around the world have had a COVID-19 vaccine.
The independent Medicines and Healthcare products Regulatory Agency (MHRA) has confirmed the Pfizer/BioNTech vaccine is very effective for children aged 5 to 15.
This followed an extensive review of the safety, quality and effectiveness of the vaccine in this age group.
The vaccine continues to be closely monitored.
Common side effects
Like all medicines, the COVID-19 vaccines can cause side effects, but not everyone gets them.
Most side effects are mild and should only last 1 or 2 days, such as:
- a sore arm from the injection
- feeling tired
- a headache
- feeling achy
- mild flu-like symptoms
Children should rest and you can give them paracetamol to help make them feel better.
