[Gateway] In some people, COVID-19 vaccination may make the situation worse, especially for those with blood coagulation problems or those, like the elderly, taking "blood thinners," even mild antiplatelet therapy such as aspirin.Thrombocytopenia is a condition characterized by abnormally low levels of blood platelets, also known as thrombocytes.
As a result, it can lead to thrombocytopenic purpura, a bleeding disorder causing the immune system to destroy platelets, which are necessary for normal blood clotting.
The symptoms of thrombocytopenic purpura can include bleeding into the skin often around the shins, rash, abnormally heavy menstruation, easy bruising, nosebleed, or bleeding in the mouth.
