A single shot to prevent HIV (and maybe other diseases) could be on the horizon! MIT scientists found a way to make a vaccine hang out in your lymph nodes for weeks, letting your body build up a super-strong defense. They combined two powerful immune boosters, and the results in mice are wild—tons of antibodies, just from one dose. Imagine getting lifelong protection from HIV or even COVID with one jab. Science is seriously leveling up! #HIVVaccine #MedicalBreakthrough #ScienceNews #Health #BodyHealth
