Side effects are important considerations when the MHRA is assessing vaccines. As with many other vaccines, the MHRA identified that some people might feel slightly unwell after receiving either of the two approved vaccines. The MHRA report that no significant side effects have been observed in the tens of thousands of people involved in trials.

All patients will be provided with information on the vaccine they have received, how to look out for any side effects, and what to do if they occur. This will include how to report side effects to the MHRA.
