HSV-1 Has Been Infecting Humans Since the Beginning of Time. No vaccine. No cure. No end in sight. Until now, there may finally be a path forward. A groundbreaking mathematical modelling study published in Science Advances just gave the clearest picture yet of what an HSV-1 vaccine could actually achieve. And the numbers are staggering. With 70% vaccine efficacy and lifelong protection, infant vaccination alone could: Reduce oral HSV-1 infections by nearly 50%. Reduce genital HSV-1 infections by nearly 60%. Avert approximately 28.5 million infections by 2075. Add adolescent catch-up vaccination and that number jumps to 41.8 million infections averted. Why genital HSV-1 specifically matters right now: Most doctors still think of HSV-1 as the cold sore virus. But the epidemiology has shifted dramatic
