Today, most vaccines are delivered via intramuscular or subcutaneous routes using a needle and syringe. In the future, novel delivery technologies may enhance the reliability and effectiveness of vaccines at the point of use while also improving safety, especially if they eliminate the need for sharps. Innovative methods such as intradermal delivery also hold promise for reducing the quantity of vaccine required for an effective dose—potentially helping to decrease costs for immunization programs.
PATH is working to improve vaccine delivery through the exploration and development of new delivery technologies. By collaborating with industry partners, manufacturers, and ministries of health, among other stakeholders, PATH strives to advance novel devices and methods that make vaccine delivery more reliable, more effective, and easier for developing countries.
