Woman contracts world's deadliest virus after unknowingly being given the wrong vaccine

A woman who was given the wrong vaccine developed a severe case of one of the world's deadliest diseases. TB typically causes a lung infection, but in this case, the otherwise healthy patient developed swelling in her arm as a result of the incorrect vaccine being administered in the wrong way ‘Administration of the BCG vaccine intramuscularly is commonly the result of an error and can lead to rare and preventable complications, even in immunocompetent patients,’ doctors who reported the case said. ‘A reasonable explanation for the error in this case is that the healthcare professional administering the vaccine confused the for the MMR vaccine.’ The person who administered the BCG vaccine did so in the way that an MMR vaccine is meant to be administered – via injection at the muscle level because the weakened forms of the viruses replicate slowly there, prompting a stronger immune response. When injected into the muscle, the bacteria was allowed to sp This led to an abscess in the 30-year-old's arm, which doctors still say is a rare occurrence ‘primarily in the pediatric population.’ The adverse effects doctors are likely to see include injection-site abscess, inflammation of the lymph nodes, chronic bone pain and mobility problems, and a body-wide infection causing fever, fatigue, swollen lymph nodes, enlarged liver, severe cough, arthritis, particularly in immunocompromised patients. The healthy 30-year-old patient was mistakenly given the vaccine for TB, which was injected improperly, resulting in a whole-body infection and a fluid-filled abscess in her deltoid muscle, indicated by the arrow The woman was treated with a variety of anti-TB medications, which were effective, ‘and she recovered fully and reported no further symptoms 6 months after initiation of the anti-tuberculosis treatment,’ the doctors said.
