Idiopathic Thrombocytopenia Purpura (“ITP”) is a disorder of the blood that involves low platelet levels that can potentially lead to increased bruising and bleeding.  Symptoms of ITP include easy and excessive bruising (purpura), nosebleeds, bloody gums, fatigue, bloody urine or stools and subcutaneous bleeding under the skin. 

ITP can follow a vaccination, viral infections, drugs, and other immune disorders.  Studies have shown that the risk of ITP increases in the six (6) weeks following administration of the MMR vaccine.

The Vaccine Injury Table reports an association between measles containing vaccines and ITP when the symptoms occur within 7 to 30 days of vaccine administration
