Scientists believe they’ve figured out how to make a century-old tuberculosis vaccine more effective.
It has less to do with the vaccine itself and more to do with how it is administered.
Researchers at the National Institutes of Health say that injecting the vaccine straight into the bloodstream dramatically improved its effectiveness over the skin-deep shot given today.
The authors of the study believe that our key immune cells or “T” cells can swarm the lungs and kill off the TB bacteria more quickly when the vaccine is directly injected into the bloodstream.
Officials say additional safety research is underway in animals with the hopes of beginning a first-step study in people in about 18 months.
