Since its founding in 1701, Yale has been dedicated to expanding and sharing knowledge, inspiring innovation, and preserving cultural and scientific information for future generations. Yale’s reach is both local and international. It partners with its hometown of New Haven, Connecticut to strengthen the city’s community and economy. And it engages with people and institutions across the globe in the quest to promote cultural understanding, improve the human condition, delve more deeply into the secrets of the universe, and train the next generation of world leaders.
An injection primes the immune system, then nanoparticles applied vaginally pull immune defenders to where herpes enters. In mice, 80 percent showed no disease for six months, versus 40 percent with the shot alone. Human trials remain distant.
