Tuberculosis (TB) bacteria can be transmitted when someone with active TB in their lungs coughs or sneezes. People whose immune system is keeping TB under control (latent TB) can take a course of medication known as isoniazid preventive therapy in order to reduce their risk of developing active TB disease. Research is ongoing into a vaccine that could be given to people with latent TB.

  • 49th Union World Conference on Lung Health: Integrating HIV treatment and TB preventative therapy greatly improves IPT adherence

    When tuberculosis preventive therapy is delivered with HIV treatment services and patients get a choice in where they access treatment, completion of tuberculosis preventive therapy rises, helping to ensure people living with HIV stay healthy, researchers said here.

  • 49th Union World Conference on Lung Health: First promising TB vaccine candidate in 100 years needs more resources, researchers say

    It's taken 100 years to see any progress in the development of a vaccine to prevent tuberculosis, a disease that kills 4,000 every day, Lucica Ditiu, executive director of the Stop TB Partnership said here. Even now, it remains uncertain that a new vaccine will see the light of day, she said, as more funding has yet to be secured for larger-scale trials to confirm the promising results of the M72 vaccine candidate.

  • TB vaccine trial results offer potential for BCG Revaccination, hope for subunit vaccines

    Aeras, a nonprofit organization dedicated to developing vaccines against tuberculosis (TB), today announced results from an innovative clinical trial that provides encouraging new evidence that TB vaccines could prevent sustained infections in high-risk adolescents. In a prevention-of-infection Phase 2 trial conducted in South Africa, revaccination with the Bacille Calmette-Guerin (BCG) vaccine significantly reduced sustained TB infections in adolescents. An experimental vaccine candidate, H4:IC31, also reduced sustained infections, although not at statistically significant levels.

  • Proactively treating HIV patients at risk for tuberculosis with multidrug TB therapy doesn’t save more lives

    In what investigators say is a surprise finding, results of a new study appear to strongly affirm the effectiveness of prescribing the anti-tuberculosis drug isoniazid alone — in place of the standard four-drug regimen — to prevent TB and reduce death in people with advanced HIV/AIDS infections. Those with HIV and AIDS are highly susceptible to TB.

Community Consensus Statement on Access to HIV Treatment and its Use for Prevention

Together, we can make it happen

We can end HIV soon if people have equal access to HIV drugs as treatment and as PrEP, and have free choice over whether to take them.

Launched today, the Community Consensus Statement is a basic set of principles aimed at making sure that happens.

The Community Consensus Statement is a joint initiative of AVAC, EATG, MSMGF, GNP+, HIV i-Base, the International HIV/AIDS Alliance, ITPC and NAM/aidsmap
