evidence: The MMR vaccine can cause mild to severe adverse reactions. Mild problems include fever, rash, and swelling. However, the vaccines can also cause seizures, severe allergic reactions, pain and stiffness in joints, blood disorders involving low platelet counts such as immune thrombocytopenic purpura, also known as ITP. The MMR vaccine has also been associated with deafness, coma, permanent brain damages, and death. [...] - Encephalopathy or Encephalitis – Encephalopathy and encephalitis are brain diseases that have been linked to the MMR vaccine and various other vaccinations. Initial symptoms include confusion, drowsiness, severe headaches, fever, vomiting and seizures. While most individuals diagnosed with encephalopathy or encephalitis can fully recover, in some cases treatment and physical or occupational therapy may be necessary. [...] The Vaccine Injury Table, part of the law Congress passed to assist in adjudicating vaccine injury cases, specifies certain injuries which are known to be related to MMR vaccine, or any of its components including anaphylaxis (severe allergic reaction), anaphylactic shock, encephalopathy (brain damage meeting certain legal definitions) and encephalitis (swelling of the brain). Other injuries can also be compensated if the injured person can demonstrate a causal relationship between the MMR vaccine and injury.
