US researchers at the Massachusetts Institute of Technology have been testing a new microscopic particle that could help combine all of the vaccinations in the first year of a baby’s life (Diphtheria, tetanus, whooping cough, polio, Hib, and even more) in one quick jab.

As said on BBC, “A team at Massachusetts Institute of Technology has designed a new type of micro-particle that could combine [all shots until age one] into a single jab…a library of tiny, encased vaccine particles, each programmed to release at a precise, predictable time, so that people could potentially receive a single injection that, in effect, would have multiple boosters already built into it.”
