 Vaccines are a vital tool in preventing the spread of infectious diseases. They work by introducing a weakened or inactive form of the virus or bacteria into the body, triggering an immune response. This prepares the body to fight off future infections and protects not only the individual but also the community. Vaccines have saved countless lives and continue to be a critical part of public health.

Vaccines play a crucial role in building immunity and safeguarding public health by preventing the spread of infectious diseases. Their effectiveness in protecting individuals and communities cannot be overstated.
