Seize the Momentum on TB Vaccine Development

Extensive groundwork is being laid out for a new TB vaccine in clinical sites and research institutions across Africa—lab capacity and field sites are being set up, health professionals are being trained, epidemiological studies are underway.

At a Congressional briefing, three African researchers detailed the progress made and challenges ahead in the search for a new, more effective TB vaccine to replace the 90-year-old BGC vaccine now being used in the developing world. BGC offers some protection against severe forms of TB most often contracted by children, but it is not very effective against adult pulmonary TB. Additionally, it may case BCG disease in infants who are HIV positive.

The search for a new vaccine has taken on increased urgency in the context of the HIV epidemic, which has reignited TB across the developing world, said the panelists at today’s briefing, co-sponsored by Aeras and the Global Health Council.
