Should I be worried about blood clots?

Vaccines are the best way out of this pandemic and provide strong protection against Covid. For the vast majority of people, the benefits of the vaccine in providing protection against the serious consequences of Covid far outweigh any risks.

There have been reports of an extremely rare adverse event involving blood clots with low levels of platelets after vaccination with the AstraZeneca vaccine. Similar conditions can occur naturally, and clotting problems are also a common complication of Covid infection. As a precaution, people whose risk is greater, albeit still extremely small, will only be offered appointments for other vaccines.
