Does it work against new variants?

Like all viruses, the Covid virus mutates and that means that we will see new variants arising from time to time. Research has shown the current vaccines help to:  

  • Reduce your risk of getting seriously ill or dying from COVID-19.  
  • Reduce your risk of catching or spreading COVID-19.  
  • Protect against COVID-19 variants.  

The 1st dose should give you some protection from three or four weeks after you've had it. But you need two doses for stronger and longer-lasting protection. 

Most people also need a booster dose to help improve the protection from the first two doses of the vaccine.

Q&As

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.

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

Has it been tested?

The approved vaccines have met strict standards of safety and quality. They have been tested on tens of thousands of volunteers in multiple clinical trials and given to millions of people. Reports of serious side effects have been extremely rare, but some vaccines may be recommended for people under 40.
