Vaccine and Needle-Free Vaccination Delivery System

Needle-free injection delivery system is a new method use a unique profile to deliver vaccine to the proper tissue depth for injection. The shift from needle-based to needle-free immunization is also catalyzed, in part, by the realization that skin, which can increase vaccine immunogenicity, is ideal target for vaccine delivery. As a promising delivery of vaccines system, it has the potential to decrease the dose of vaccine antigen, enhance immune response and may furthermore help to reduce costs.
