Information about the AstraZeneca COVID-19 vaccine

There has been extensive press coverage regarding the AstraZeneca COVID-19 vaccine in recent days. The UK independent medicines regulator the MHRA (Medicines and Healthcare Products Regulatory Agency) has extensively reviewed all evidence around the AZ vaccine. 

COVID-19 vaccinations are the most important safe way of reducing the risks of COVID-19 illness. The AZ vaccine is safe, and effective, and has been associated with an extremely rare risk of blood clots – at 4 cases per 1 million doses.

However, due to the extremely low risk of blood clots, those aged under 30 years or with a risk of blood clots may be offered another vaccine; any concerns should be discussed with your GP. Those who have received one dose of AZ, should get their second dose of AZ.
