Vaxzevria – Oxford-AstraZeneca vaccine

What are the early signals of potential blood clotting events following immunization that people should be aware of?

As of April 2021, more than 25 million doses of the AstraZeneca vaccine have been administered in Europe and more than 27 million doses of the Covishield vaccine (AstraZeneca vaccine licensed by Serum Institute of India) have been administered in India. In very rare cases, unusual blood clots associated with thrombocytopenia have been reported within 4-20 of getting the vaccine.

It is important to be aware of the following symptoms if they should occur following vaccination: shortness of breath, chest pain, leg swelling or persistent abdominal pain. Additionally, anyone with neurological symptoms including severe or persistent headaches or blurred vision after vaccination, or who experiences skin bruising (petechia) beyond the site of vaccination after a few days, should seek prompt medical attention.
