professor beverly hunt is an international expert and john bose's and the formation of blood clots and blood vessels we're so happy to have you here with us you are like i said an international expert you just heard that am a moments ago say we endorsed basically the astra zeneca vaccine yet it's still him a suspended in several dozens of countries here in the european union what exactly is the risk here with these blood clots ok well i think people don't realize just how common blood clots are so every year if you look at a 1000 people one to 2 of them will have a deep vein thrombosis or pulmonary embolism. and so few think about that and see risk means that in the week if you've got a 1000000 people about 20 people in a week will be having a clot and if you look at the u.k. vaccine data we have facts in 8817000000 people with either the 3rd. or astra zeneca vaccine and if we look at the week off to the vaccine we should naturally expect 340 blood clots to occur in the public and if you look at the u.k. day said there are less than 60 so actually the rates of blood clots is lower off
