A vaccine is a biological preparation designed to stimulate the immune system to recognize and combat harmful pathogens, such as viruses or bacteria, without causing the disease itself. By introducing a harmless part of a pathogen—like a protein, inactivated virus, or mRNA—vaccines train the body to mount a defense if exposed to the real threat in the future. Vaccines have been one of the most powerful tools in public health, helping to control, eliminate, or even eradicate diseases like smallpox, polio, and measles. Ongoing research continues to expand vaccine technology, including mRNA platforms and universal vaccine approaches, to address emerging infectious threats and improve global health.
