J&J: Potential HIV vaccine falls short in mid-stage study

Johnson & Johnson says its potential HIV vaccine did not provide protection against the virus in a study of young women in sub-Saharan Africa

A potential HIV vaccine being developed by Johnson & Johnson did not provide protection against the virus in a mid-stage study, the drugmaker said Tuesday. J&J plans to end that study, which involved young women in sub-Saharan Africa. But researchers will continue a separate, late-stage trial involving a different composition of the vaccine in men and transgender people. The study in sub-Saharan Africa involved about 2,600 women who were deemed to be at high risk of acquiring HIV, which causes AIDS. Participants were randomly selected to receive either the vaccine or a placebo, and researchers found that the vaccine was only 25% effective at preventing HIV. “HIV is a unique and complex virus that has long posed unprecedented challenges for vaccine development because of its ability to attack, hijack and evade the human immune system,” J&J Chief Scientific Officer Dr. Paul Stoffels said in a statement.
