9 aprile 2021 – EMA’s safety committee (PRAC) has concluded today that unusual blood clots with low blood platelets should be listed as very rare side effects of Vaxzevria (formerly COVID-19 Vaccine AstraZeneca). People who have received the vaccine should seek medical assistance immediately if they develop symptoms of this combination of blood clots and low blood platelets. However, COVID-19 is also associated with a risk of hospitalisation and death. The reported combination of blood clots and low blood platelets is very rare, and the overall benefits of the vaccine in preventing COVID-19 outweigh the risks of side effects, according to the PRAC.
