Like all viruses, the Covid virus mutates and that means that we will see new variants arising from time to time. The Delta variant, which passes easily from person to person, is the dominant strain of the virus in the UK at the moment.
A recent study has shown that whilst a single dose of vaccine is less effective against the Delta variant than against previous versions of the virus, having two doses of vaccine is highly effective against this variant at preventing the disease. It’s important that you get your second dose to get the best protection.
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 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.
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.
