Gates Foundation Funds Microneedle Patch for Needle-Free Measles-Rubella Vaccination Without Cold Chain
The Gates Foundation funded development of a dissolvable microneedle patch for combined measles-rubella vaccination, developed by Micron Biomedical and the Georgia Institute of Technology. The patch is applied to the skin like a bandage, delivering vaccine antigens through 100 microscopic tips that dissolve within minutes. Unlike injectable vaccines, the patch requires no needles, no trained injectors, and no cold chain — shelf-stable at room temperature for one year. Clinical trials in adults in The Gambia validated safety and immunogenicity, establishing proof of concept for patch delivery of live-attenuated viral vaccines.

Gates-backed World Mosquito Program reaches 16 million people protected from dengue via Wolbachia method
The World Mosquito Program — backed in part by the Gates Foundation — announced in January 2026 that its Wolbachia-infected mosquito releases had reached over 16.1 million people across multiple countries, including Colombia, Indonesia, Brazil, Sri Lanka, Fiji, Vanuatu, and Vietnam. Wolbachia-carrying Aedes aegypti mosquitoes — which block dengue, Zika, chikungunya, and yellow fever transmission — had established self-sustaining populations in treated cities without requiring ongoing releases. Gold-standard randomised trials in Indonesia showed a 77% reduction in dengue incidence. The program represented one of the largest and most cost-effective vector control deployments in history.
