Microparticle Drug Delivery Could Revolutionize Multi-Dose Vaccines

Boston, USA: Researchers unveiled a microparticle system capable of releasing multiple vaccine doses at scheduled intervals post-injection—potentially removing the need for follow-up shots. Each microparticle contains a specific payload and dissolves at a set time (weeks or months later), ensuring the body receives booster doses without separate appointments. Such technology, tested in animal models, could transform global immunization, especially in regions where access to clinics is limited. Next steps include human trials to confirm safety and precise timing controls.
