How safe is the COVID-19 vaccine?
The vaccines approved for use in the UK have met strict standards of safety, quality and effectiveness set out by the independent Medicines and Healthcare products Regulatory Agency (MHRA).
Any coronavirus vaccine that is approved must go through all the clinical trials and safety checks all other licensed medicines go through. The MHRA follows international standards of safety.
Other vaccines are being developed. They will only be available on the NHS once they have been thoroughly tested to make sure they are safe and effective.
So far, thousands of people have been given a COVID-19 vaccine and reports of serious side effects, such as allergic reactions, have been very rare. No long-term complications have been reported.
To find out more about the vaccines approved in the UK, see:
- GOV.UK: Pfizer/BioNTech vaccine for COVID-19 approved by MHRA
- GOV.UK: Oxford/AstraZeneca vaccine for COVID-19 approved by MHRA
- GOV.UK: Moderna vaccine for COVID-19 approved by MHRA
How effective is the COVID-19 vaccine?
The 1st dose of the COVID-19 vaccine should give you good protection from coronavirus. But you need to have the 2 doses of the vaccine to give you longer lasting protection.
There is a small chance you might still get coronavirus even if you have the vaccine.
This means it is important to:
- continue to follow social distancing guidance
- if you can, wear something that covers your nose and mouth in places where it's hard to stay away from other peopl
COVID-19 vaccine side effects
Most side effects are mild and should not last longer than a week, such as:
- a sore arm where the needle went in
- feeling tired
- a headache
- feeling achy
You can take painkillers, such as paracetamol, if you need to.
If you have a high temperature you may have coronavirus or another infection.
If your symptoms get worse or you are worried, call 111.
Tell healthcare staff before you are vaccinated if you've ever had a serious allergic reaction (anaphylaxis).
You should not have the vaccine if you've ever had a serious allergic reaction to:
- a previous vaccine
- a previous dose of the same COVID-19 vaccine
- some medicines, household products or cosmetics
Serious allergic reactions are rare. If you do have a reaction to the vaccine, it usually happens in minutes. Staff giving the vaccine are trained to deal with allergic reactions and treat them immediately.
COVID-19 vaccine ingredients
The approved COVID-19 vaccines do not contain any animal products or egg.
Advice if you're of childbearing age, pregnant or breastfeeding
There's no evidence the COVID-19 vaccine is unsafe if you're pregnant.
The JCVI has updated its advice to recommend you may be able to have the vaccine if you're pregnant and:
- at high risk of getting coronavirus because of where you work
- have a health condition that means you're at high risk of serious complications of coronavirus
You can have the COVID-19 vaccine if you're breastfeeding.
Speak to a healthcare professional before you have the vaccination. They will discuss the benefits and risks of the COVID-19 vaccine with you.
You do not need to avoid pregnancy after vaccination. The vaccine cannot give you or your baby COVID-19.
