To fight HIV, the development of immunization strategies must keep up with how quickly the virus modifies itself. Now, Boston Children’s Hospital researchers are developing models to test HIV vaccines on a faster and broader scale than ever before with the support of the Bill & Melinda Gates Foundation.

“The field of HIV research has needed a better way to model the immune responses that happen in humans,” says Frederick Alt, PhD, director of the Boston Children’s Program in Cellular and Molecular Medicine, who is leading the HIV vaccine research supported by the Gates Foundation.

The researchers are racing against HIV’s sophisticated attack on the human immune system. HIV, the human immunodeficiency virus, mutates much faster than other pathogens. Within each infected patient, one virus can multiply by the billions.
