Dr. Ronan Glynn:

There is still significant uncertainty around the extent to which this is an issue. From NIAC's perspective, it was conservative; it took all events to date and assumed they were all these very serious clotting events, whereas we do not know that to be the case just yet because some of them remain under investigation. However, we know that somewhere between four and ten of these events will happen for every million people who are vaccinated. To date, the EMA has only been notified of approximately one fatality per million people vaccinated. Therefore, the majority of people - at least of the cases notified to date - with these conditions have survived. It is a serious condition but the majority of people have, as I said, survived. To come back to my earlier point, the risk of a person in their 60s dying from Covid is 85% higher than their risk of suffering one of these clotting events and in the event they suffer one it is not a given, as I said, that it will be a fatal event. Thus the balance is firmly in favour of getting the vaccine for anyone who is offered it.
