Astrazeneca COVID-19 vaccine and blood clots

Professor Anthony Harnden, Deputy Chair of the Joint Committee on Vaccination and Immunisation (JCVI), has responded to claims that the vaccine is associated with blood clots: “Safety is paramount and we have been monitoring this issue closely. The UK has administered 11 million doses of the AstraZeneca vaccine and there has been no demonstrable difference in the number of blood clots since the vaccine was introduced. The vaccine has been rigorously tested for safety and approved by the European Medicines Agency, MHRA and WHO, so people should continue to take it.”
