Recently it has emerged that the astrazeneca vaccine can, in rare cases, cause blood clotting which can be fatal. So far the message in the media seems to be that we should take the vaccine anyway because the benefits still outweigh the risks. And there’s been a lot of comparison of the risk of blood clotting as a result of the vaccine with other activities and medicines that carry a similar risk. However, I haven’t seen any comparisons with other vaccines that we take for other diseases. Does anyone know whether there is a risk of death from any other vaccine that we take for other diseases? As far as I can tell there doesn’t seem to be.
