Tuberculosis Vaccine Efficacy Boosted Dramatically by IV Administration

Researchers at the University of Pittsburgh School of Medicine and the National Institute of Allergy and Infectious Diseases have found that changing how the tuberculosis vaccine is administered can dramatically increase its protective power. The team’s study showed that administering the BCG vaccine intravenously rather than by injection into the skin boosted its ability to protect rhesus macaques from infection following exposure to Mycobacterium tuberculosis.
