Scientists create DNA-based TB vaccine
Researchers have developed an experimental therapeutic vaccine against tuberculosis using DNA technology. It is administered via the nasal route and shows promising results in eliminating bacteria and reducing lung inflammation when used alongside standard drugs. The study, published in the Journal of Clinical Investigation, indicates that the vaccine targets drug-resistant persistent bacteria, representing an important step toward developing an effective vaccine, although human clinical trials are still planned. Tuberculosis remains a deadly infectious disease, with over 10 million people infected in 2024 and approximately 1.2 million fatalities among them.
