Pediatric immunization refers to the process of vaccinating children to protect them from various infectious diseases. Vaccines stimulate the immune system to recognize and fight specific pathogens, helping to prevent illnesses such as measles, mumps, and whooping cough. Immunizations are typically administered during regular check-ups in early childhood, following recommended schedules set by health organizations. These vaccines not only safeguard individual children but also contribute to community health by achieving herd immunity. When a significant portion of the population is vaccinated, the spread of diseases is reduced, protecting those who cannot be vaccinated, such as infants or individuals with certain medical conditions.
