The UK Medicines and Healthcare Products Regulatory Authority said it had detected 30 cases of rare blood clots when using AstraZeneca for Covid-19, 25 more than previously reported.
He explained that he had not received any reports of clotting after using Biontech and Pfizer vaccine. And the agency said seven of those who received the AstraZeneca vaccine died while registering rare blood clots.
He emphasized that the benefits of the vaccine in preventing Covid-19 far outweigh the potential risks of developing blood clots.
Some countries impose restrictions on the use of AstraZeneca, while others have continued to vaccinate by continuing studies on a few, sometimes serious, blood clots.
