Hematologist said from the last year, caller's type and screen from Dec2020, and type and screen done in Dec2021, did caller have any health issues what so ever, caller said no pretty healthy other than cancer diagnosis, caller didn't have anything. Only thing caller had done was that caller had the 2 Covid shots, didn't have 3rd dose at that time until spring. Physician said that is interesting. Caller didn't have a reaction to any of the shots, or anything, then HCP told caller that as a hematologist department starting to find more people having strange things happening in blood. Has seen an increase in people getting blood clots. Initially when people get the Covid shots, seeing uptick in blood clots 6-8 weeks after getting the shot, caller read that in the paper. HCP said no one is talking about people like caller who come back like a year later and have strange antibodies and antigens in blood, does not make any sense and cannot find any government data on this.
