How long does protection last?

It’s too soon to know how long immunity will last following vaccination, but it’s thought that protection lasts for at least 6 months and possibly longer. You need two doses for stronger and longer-lasting protection. Booster doses of Covid vaccine may be needed to maintain protection for you and those around you, or to fight new variants of the virus.

Q&As

Asked 14 Jun

Will it give me Covid?

You can’t catch Covid from the vaccine. It may take a few weeks for your body to build up protection against the virus, but it will reduce your chances of becoming seriously ill. You need to have both doses for maximum protection.

Asked 14 Jun

How was it made so quickly?

The Covid vaccines have been developed, assessed and independently approved using the same processes that would normally be used to develop a vaccine. They have been through clinical trials involving tens of thousands of volunteers, a testing process which tells us they are safe and effective.

Asked 14 Jun

Should I get it now?

Millions of people have now been vaccinated against Covid. The vaccine is the best defence against the virus, so the sooner you're vaccinated, the sooner you’ll begin to protect yourself and your community. Vaccinating as many people as possible should reduce the levels of local infections too.
