They are reporting links this morning of blood clots to AZ . it was difficult to report side effects because the site was set up extremely difficult.
in the end I tried the doctor, and the dentist to report side effects
If you mean that yellow site it is a nightmare to fill the online form in. Really all is you should have needed was your name, age, doctor's name and where the vaccine was administered, your symptoms and the batch number. Instead I had to plough through loads of irrelevant stuff as well. I almost gave up at one point.
