Yes, vaccines are one of the most effective tools in medicine for preventing infectious disease. Here's why: How they work: Vaccines train the immune system to recognize and fight specific pathogens (viruses or bacteria) by exposing it to a harmless component or weakened/inactivated form of the pathogen. This primes the immune system to respond quickly and effectively if the person is later expos
