There is no cure for HIV. While scientists have made considerable progress in controlling the infection, patients still must take daily antiretroviral medication for the rest of their lives. Results from a clinical trial led by Rockefeller, Imperial College London, and the University of Oxford (RIO) have offered a new strategy, suggesting that just one or two doses of broadly neutralizing antibodies (bNAbs) can suppress the virus long term, keeping it at undetectable levels for months and even years.
