We have received a small number of queries from patients who are concerned about reports of blood clots in patients who have received the Astra Zeneca vaccination. There is much on the matter in the press at the moment and it may be helpful to present some facts that we hope will help you to make your decision, if you are in any doubt.
Blood clots are a common condition, particularly among older people who are currently prioritised for vaccination.
Based on the 37 reported cases of blood clots in the 17 million people who have received the Oxford Astra Zeneca vaccine, the chance of developing a blood clot after vaccination is 2 per million.
Vaccinations aside, your chance of developing a blood clot is:-
3,000 per million if you are over 80
400 per million if you are over 50
200 per million if you are pregnant
160 per million if you are 25
47,000 per million if you catch Covid-19
