LONDON (AP) — The world's most advanced tuberculosis vaccine failed to protect babies against the infectious disease, according to a new study in South Africa.
The vaccine, MVA85A, was designed to improve protection from the only existing tuberculosis vaccine, BCG, which is routinely given to newborns. Though the new vaccine appeared safe, scientists found no proof it prevented tuberculosis, an airborne disease that kills more than 1 million people worldwide every year.
