You get the best protection from two doses. Anyone who has had their first AstraZeneca dose, except those who have experienced blood clots with low platelets should get their second dose.
For the AstraZeneca vaccine, side effects are generally less common after the second dose than after the first dose. There have been extremely rare cases of blood clots following the first dose of the vaccine, and an even smaller number of cases following a second dose.
Whilst your first dose of vaccine gives you some protection against severe disease, having your second dose gives you stronger and long-lasting protection against the virus.
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.
Will it affect my fertility?
There have been a lot of rumours that the Covid vaccines could affect women’s fertility, but research has shown these are not true. They do not contain any ingredients that could affect fertility and there’s no likely way they could.
