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.
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.
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.
Will I have side effects?
Like all vaccines, and medicines, there can be side effects, but most are mild and short-term and not everyone gets them. Any side effects following the jab usually last less than a week.
