Oxford Astra Zeneca Covid-19 vaccine
FAQs - related to incidence of PE/DVT (blood clots)
Why is it in the news?
There have been a small number of cases of DVT/PE - blood clots in legs or lungs in patients who have had the Oxford AZ vaccine. It is important to remember that nearly 20 million doses of Oxford AZ vaccine have been safely given all over the world.
Should you be getting the vaccine if you are booked to get your Oxford AZ jab?
YES. Everyone who is offered a covid vaccine should take the vaccine as planned.
Should I insist on getting Pfizer vaccine instead?
NO. We have no control over the supply chain and insisting on Pfizer is likely to delay your vaccination putting you and your loved ones at much higher risk of Covid and it's complications.
Should I avoid vaccination altogether due to risk of blood clots?
NO. You should get your Covid vaccine when offered. Getting Coronavirus infection itself increases your risk of getting DVT or PE (blood clots). Studies have shown that up to 20-30% (or more when admitted to ICU) of critically ill Covid patients develop DVT or PE.

It is safe and extremely important that you have either the Oxford AstraZeneca vaccine or the Pfizer vaccine when offered.
Overwhelming numbers of experienced doctors, research scientists, WHO (World Health Organization), MHRA UK (Medicines and Healthcare products Regulatory Agency), EMA (European Medicines Agency) have all advised that the Oxford AstraZeneca vaccine is safe to use in all groups of patients.
There is extremely good evidence that the Oxford AZ vaccine reduces the risk of catching Covid infection, minimises the risk of hospitalisation with Covid illness while also reducing the risk of spreading Covid infection to other people.
Hence it is important to have your Covid vaccines when you are sent an invitation to book your appointment.
