Vaccination:
Vaccination, also known as immunization, is a proactive and preventive measure to bolster the immune system’s ability to fight off specific infections. It works by introducing harmless antigens, often in the form of weakened or inactivated pathogens or their components, into the body. These antigens stimulate the immune system without causing illness, allowing the body to recognize and remember the pathogen. This means that if the person is exposed to the actual pathogen in the future, their immune system can respond rapidly and effectively, preventing or mitigating the disease. Vaccines have been instrumental in controlling and eradicating numerous infectious diseases and are a cornerstone of public health efforts worldwide.
