Lifesaving Power of Vaccines: Types and Must-Have Immunizations for Adults

Vaccines are biological preparations designed to provide immunity to a specific disease. They stimulate the body's immune system to recognize and fight pathogens like bacteria or viruses without causing the illness itself. Vaccines typically contain weakened or inactivated parts of the pathogen or its toxins, or they may use a small piece of its genetic material. This triggers the immune response, helping the body "remember" the pathogen, so it can respond quickly if exposed to it in the future.
