Personally I do not understand why anyone wouldn't get the vaccine as covid and the delta variant are deadly! My son's friend, young & healthy got covid last November & is still having heart issues, getting better but still some problems.
Anyway you didn't ask about my opinion. My hematologist said get it - my PCP said get it - I said I'd get it even before they said for me to get it. Was not nervous, did not check platelet count before or after, I was just very thankful I was able to get the vaccine (Pfizer) - and to be honest as soon as they say come get the booster I'll be there fast! I have had ITP since 1989.
