Vaccination plays a pivotal role in achieving herd immunity. When a large percentage of the population is vaccinated, the spread of infectious diseases is minimized. This lowers the overall amount of pathogen in the community, making it harder for diseases to spread and protecting those who cannot be vaccinated. Common vaccines in pediatric care include the MMR (measles, mumps, rubella) vaccine, the DTaP (diphtheria, tetanus, pertussis) vaccine, and the polio vaccine.
