No, other vaccines certainly do not have the same thrombosis risk as AZ. We easily have enough data here that we would have seen that by now. There is the myocarditis risk for the mRNA vaccines, but that is quite a different thing than the thrombosis risk for AZ. The myocarditis is not deadly. The argument for vaccination of young boys is more complex, and different expert panels have come to different conclusions there. The UK is more of an outlier in this case. There is still enough uncertainty here, especially on the consequences of the infection itself that it's a really difficult decision. As for point C, there is no reason to believe that Novavax would be safer than the mRNA vaccines. It could be, but there isn't anything inherently superior here that would automatically make it safer.
