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.
