Childhood vaccinations play a crucial role in preventing infectious diseases and improving global public health. Immunization stimulates the immune system to develop long‑lasting protection against dangerous pathogens. Vaccines help reduce child mortality, prevent outbreaks, and create herd immunity, protecting those who cannot be vaccinated.
