The UK vaccination programme has been very successful, with over 30 million people vaccinated and 6,000 lives saved.
There have been some reports of a very rare condition involving blood clots. Although extremely rare, there appears to be a higher risk in people shortly after the first dose of the AstraZeneca vaccine. Around 4 people develop this condition for every million doses of AstraZeneca vaccine doses given.
This is seen slightly more often in younger people and tends to occur between 4 days and 2 weeks following vaccination.
Although very rare, if you experience a severe headache, unexplained bruising, shortness of breath, chest pain, leg swelling or persistent abdominal pain 4 days to 4 weeks after vaccination, seek medical advice urgently.
If you are over 30 or have an underlying health condition, the benefits of having the AstraZeneca covid-19 vaccination far outweigh the risks and you should still get both the first and second doses, if not already.
If you are under 30 and have already had the first AstraZeneca dose without any serious side effects, you should still get the second.

An information leaflet on covid-19 vaccination and blood clotting is available on the Public Health England.
