Precautions and contraindications

I have had a blood clot in the past or I have a family history of blood clotting. Should I still get vaccinated against COVID-19?

You can still get any of the licensed COVID-19 vaccines, including the Oxford-AstraZeneca COVID-19 Vaccine if you have recently had a blood clot, take blood thinning medicine or have a family history of blood clotting. You do not need to cancel or delay vaccination. You should also not receive any antiplatelet or anticoagulant treatment in the days before or after vaccination if it was not previously prescribed by your physician because of your illness. A vaccinated person, regardless of the vaccine used, should continue the usual treatment he or she may receive (including any antithrombotic treatment).

Like everyone who gets the vaccine, you should be aware of the symptoms to look out for and seek urgent medical care if you have any signs or symptoms of blood clotting, such as shortness of breath, chest pain, leg swelling, persistent abdominal pain following vaccination. Additionally, anyone with neurological symptoms including severe or persistent headaches and blurred vision after vaccination, or who experience skin bruising (petechia) beyond the site of vaccination after a few days, should seek prompt medical attention.
