A blood disorder that affects the platelets has been reported in at least 2 dozen people who received Covid-19 mRNA vaccines in the United States.

Thrombocytopenia is among the adverse effects reported to the Vaccine Adverse Event Reporting System (VAERS) system, which is jointly run by the U.S. Centers for Disease Control and Prevention and the U.S. Food and Drug Administration.

Thrombocytopenia is an abnormally low platelet count in the blood. A normal human platelet count ranges from 150,000 to 450,000 platelets per microliter of blood.

Low platelets causes abnormal bleeding, weakness and fatigue.

Signs and symptoms of low platelet count are frequent nosebleeds, bleeding gums, bruising all over the body, longer periods in women, small red or purple spots on the skin, spontaneous bleeding under skin, blood filled blisters inside the mouth.

MSN reports that by the end of January, 32 cases of a decreased platelet count, 14 cases of thrombocytopenia, and 11 cases of immune thrombocytopenia were recorded in people who had received either Pfizer or Moderna COVID vaccines in the U.S.

If you notice any unusual signs of bleeding after getting the mRNA vaccine, contact your doctor or healthcare provider immediately.
