Multiple injections for vaccinations could
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.
Researchers say the approach could allow multiple vaccines to be delivered at once and remove the need for booster jabs. It may also prove handy in treatments for allergies, diabetes and even cancer where multiple injections are needed.
Researchers say it could prove valuable in developing countries, potentially allowing all childhood vaccines and their boosters to be given in one shot.
