Particles carrying multiple vaccine doses could reduce the need for follow-up shots

May 15, 2025
Around the world, 20 percent of children are not fully immunized, leading to 1.5 million child deaths each year from diseases that are preventable by vaccination. About half of those underimmunized children received at least one vaccine dose but did not complete the vaccination series, while the rest received no vaccines at all.To make it easier for children to receive all of their vaccines, MIT r

Two HIV vaccine trials show proof of concept for pathway to broadly neutralizing antibodies

May 15, 2025
A decades-long scientific challenge in HIV vaccine development has been finding a way to train the immune system to produce antibodies that can target many variants of the virus. Traditional approaches haven't worked -- largely because HIV mutates rapidly and hides key parts of itself from the immune system. Now, a new study combining data from two separate phase 1 clinical trials shows that a tar
