Now a study published in the September 1st issue of mBio, an online open-access journal of the American Society for Microbiology, provides a biological explanation for the phenomenon.

Vaccines have been tried before: two different HIV vaccines were tested in Thailand, reducing transmission rates by close to 30 per cent.

Now, researchers at the National Institutes of Health in the US are trying to make HIV transmission a thing of the past, by strategically designing broadly neutralising antibodies based on samples taken from patients with chronic HIV.
