Microparticles enable vaccines to be “self-boosting”

Vaccination against many diseases—including polio and COVID-19—require multiple shots over time. But new technology being developed by MIT scientists could allow people to receive a complete course of a vaccine in one shot. Cup-like microparticles made of special polymers release their contents at separately timed intervals, so that one jab could provide full inoculation. In addition to increasing patient compliance, the technology could be useful for administering childhood vaccinations in underdeveloped countries that lack access to care.
