(Reuters) -British regulators on Thursday said they have identified 30 cases of rare blood clot events after the use of the AstraZeneca (NASDAQ:AZN) COVID-19 vaccine, 25 more than the agency previously reported.

The Medicines and Healthcare products Regulatory Agency said it had received no such reports of clotting events following use of the vaccine made by BioNTech SE (NASDAQ:BNTX) and Pfizer Inc. (NYSE:PFE)

The health officials said they still believe the benefits of the vaccine in the prevention of COVID-19 far outweigh any possible risk of blood clots.

Some countries are restricting use of the AstraZeneca vaccine while others have resumed inoculations, as investigations into reports of rare, and sometimes severe, blood clots continue.
