At the AACR conference in San Diego, new experimental cancer vaccines were unveiled showing early promise.

These vaccines vary from ready-made forms to custom injections based on individual tumor genetics.

Researchers aim to develop affordable, personalized vaccines to teach the immune system to attack tumors.

This innovation is a milestone in cancer treatment, aiming for specificity in targeting tumor cells.

Angus Chen, a seasoned health and science journalist, reports on these developments for STAT.
