Microparticles Could Be Used to Deliver 'Self-Boosting' Vaccines

Most vaccines, from measles to Covid-19, require a series of multiple shots before the recipient is considered fully vaccinated. To make that easier to achieve, MIT researchers have developed microparticles that can be tuned to deliver theiir payload at different time points, which could be used to create "self-boosting" vaccines.
In a new study, the researchers describe how these particles degrade over time, and how they can be tuned to release their contents at different time points. The study also offers insights into how the contents can be protected from losing their stability as they wait to be released.
