Has it been tested?

All the vaccines have been through clinical trials involving tens of thousands of volunteers. This is a rigorous testing process which produces evidence of the vaccine’s safety and effectiveness.

The MHRA, the body that regulates medicines in the UK, carried out a rigorous scientific assessment of all of the available evidence for each of the vaccines and took advice from the Commission on Human Medicines before approving the vaccines for use in the UK. The MHRA has determined that all vaccines are safe and effective in the fight against Covid.

Currently the Joint Committee for Vaccinations and Immunisations (JCVI) has advised that it is preferable for people under 40 to have a vaccine other than Oxford/AstraZeneca.

The MHRA has a legal duty to constantly assess all of the vaccines being used. A safety monitoring process is in place, and the MHRA regularly publishes reports on Covid vaccine safety.

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

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.
