Yes. Vaccines are one of the most effective tools we have to prevent infectious disease. Why they work - They train your immune system to recognize a germ before you encounter the real thing, creating immune “memory” that prevents or blunts illness. - Even when they don’t fully block infection, they markedly reduce severe disease, hospitalization, and death, and can lower transmission. Real‑worl
