Late last year, Moderna had reported it was working on a vaccine for HIV. Just last month, the vaccine began clinical trials. “We are tremendously excited to be advancing this new direction in HIV vaccine design with Moderna’s mRNA platform. The search for an HIV vaccine has been long and challenging, and having new tools in terms of immunogens and platforms could be the key to making rapid progress toward an urgently needed, effective HIV vaccine,” according to a news release from Moderna.
