New technology could allow multiple vaccines to be delivered in single jab

A new technique allowing drugs or vaccines to be encapsulated within tiny biodegradable particles could see an end booster jabs

Multiple injections for vaccinations could become a thing of the past, according to scientists who have developed an approach for delivering many doses of different substances in just one jab.

The technology involves encapsulating drugs or vaccines within tiny particles made of biodegradable polymers. Depending on their makeup, these polymers break down at different points in time, releasing their contents into the body.
