Further MHRA response to the precautionary suspensions of COVID-19 Vaccine AstraZeneca
It has not been confirmed that the reports of blood clots were caused by the AstraZeneca COVID-19 vaccine. People should still go and get their COVID-19 vaccine when asked to do so.
Dr Phil Bryan, MHRA Vaccines Safety Lead said:
The benefits of the vaccine in preventing COVID-19, with its associated risk of hospitalisation and death, far outweigh the risks of side effects. People should go and get their COVID-19 vaccine when asked to do so.
It is still the case that it has not been confirmed the reported blood clots were caused by the COVID-19 Vaccine AstraZeneca. Blood clots can occur naturally and are not uncommon.
Our role is to continually monitor safety during widespread use of a vaccine. We have in place a proactive strategy to do this. We also work closely with our public health and international partners in reviewing the effectiveness and impact of the vaccines to ensure the benefits continue to outweigh any possible side effects.
Background:
- For further details, see our statement and advice published on 11 March
- The MHRA encourages anyone to report any suspicion or concern they have beyond the known, mild side effects on the Coronavirus Yellow Card site. Reporters do not need to be sure of a link between a vaccine and a suspected side effect but are still encouraged to report.
