Vietnam is among the countries that face the highest burden of drug-resistant TB. The VQUIN study aimed to test the efficacy of an antibiotic in preventing multi-drug resistant tuberculosis. The study recruited household members of patients with drug-resistant TB and provided them with six months of antibiotic therapy. The results showed that the antibiotic, levofloxacin, reduced the incidence of tuberculosis by half among people with the infection, while also reducing costs for the health system. The study has had a significant impact on policy, as the Vietnam National Tuberculosis Program introduced new guidelines based on this newly proven treatment in January 2024.

The VQUIN Trial has filled an important evidence gap in global guidelines, and ensures that people at high risk of drug-resistant TB can be protected against this devastating infectious disease
