Regulators in the UK have identified 30 cases of rare blood clot events after the use of the AstraZeneca coronavirus vaccine. The new number is 25 more than was reported earlier.
Some countries have restricted the use of the AstraZeneca vaccine, as authorities investigate reports of rare, and in some cases severe, blood clots in patients who have received the jab.
However, UK and EU health officials believe that the benefits of the vaccine far outweigh any possible risk of blood clots and the UK figure represents 0.6 cases per 1 million people vaccinated.
The UK has, so far, administered more than 18.1 million doses of the AstraZeneca shot.
The new figure represents 22 reports of cerebral venous sinus thrombosis — an extremely rare brain clotting ailment — as well as eight blood clotting cases associated with low blood platelets.
The regulators said they had received no such reports after the use of the BioNTech-Pfizer vaccine.
