You can’t catch Covid from the vaccine and it will reduce your chance of becoming seriously ill from the disease.
It may take a few weeks for your body to build up protection from the vaccine. And like all medicines, no vaccine is completely effective – some people may still get Covid despite having a vaccination, but if they do it should be less severe. You need to have both doses for maximum protection.
Whilst you can’t catch Covid from the vaccine, it’s possible to have caught it and not realise you have the symptoms until after your vaccination appointment. If you have symptoms, it’s important to get a Covid test. It’s still important to follow guidelines, even after receiving the jab.
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.
Should I be worried about blood clots?
For the vast majority of people, the benefits of the vaccine in providing protection against the serious consequences of Covid far outweigh any risks.
There have been reports of an extremely rare adverse event involving blood clots with low levels of platelets after vaccination with the AstraZeneca vaccine. Similar conditions can occur naturally, and clotting problems are also a common complication of Covid infection. As a precaution, people whose risk is greater, albeit still extremely small, will only be offered appointments for other vaccines.
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.
