GIVING the tuberculosis vaccine intravenously makes it far more effective, according to a new study.
Tuberculosis is one of the most infectious diseases and kills around 1.5 million people globally each year – partly because the current BCG vaccine, which is given under the skin, is unreliable.
Researchers at the University of Pittsburgh School of Medicine found that monkeys given the vaccine straight into the vein had almost total protection. Those given the standard jab had only slightly more protection than those given nothing at all.
The new approach will be tested in humans once its safety has been established.
