The vaccines approved for use in the UK have been developed by Pfizer/BioNTech and Oxford/AstraZeneca.
They 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.
How effective is the COVID-19 vaccine?
The 1st dose of the COVID-19 vaccine will give you some protection from coronavirus. But you need to have the 2 doses of the vaccine to give you the best protection.
There is a chance you might still get or spread 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 people
