This work is based on a real-life situation in which some covid vaccines are being investigated in depth in relation to some uncommon incidences of thrombosis. It's fascinating to look at the literature that shows a link between increased thrombosis in the most severe patients in the first and second And third waves of covid-19 illness. As a result, it is feasible to conclude that the covid-19 virus has a procoagulant characteristic. However, is this feature shared by all viral particles, or is it mediated or caused by the spike-protein? And if there is a link, isn't it a great aspect of the project vaccination based on this protein?.
