Immunization

Immunization is a medical process that helps protect individuals from infectious diseases by introducing a vaccine into the body. Vaccines contain weakened or inactivated parts of a specific germ (like a virus or bacteria), which prompts the immune system to recognize and fight the actual disease if encountered in the future. This helps prevent illness and can also contribute to herd immunity, protecting those who cannot be vaccinated. Immunization plays a vital role in public health by reducing the spread of contagious diseases and saving lives.
