Immunization programs are public health initiatives designed to protect individuals and communities from infectious diseases. These programs provide vaccines that help the body develop immunity against specific illnesses, such as measles, polio, and influenza. By vaccinating a large portion of the population, these programs aim to reduce the spread of diseases and prevent outbreaks. These programs are often implemented by government health agencies and may include free or low-cost vaccinations for children and adults. They also focus on educating the public about the importance of vaccines and ensuring access to immunization services, which can significantly improve overall community health.
