Safe, effective HIV vaccine
An HIV vaccine is one of the most sought-after innovations in modern medicine. Less than three years after the virus was discovered in 1983, the first HIV vaccine clinical trial was launched. Four decades later and we still don’t have a vaccine against the virus that has killed over 40 million people, including 600,000 in 2021. Although therapies that prevent HIV from spreading or developing into AIDS have made the disease manageable in wealthy nations, HIV/AIDS remains deadly in poor communities around the world. Several promising HIV vaccines are currently being studied. Here’s hoping at least one is finally successful.
