Immunization

Immunization is the process by which a person becomes immune to an infectious disease, usually through the administration of a vaccine. Vaccines stimulate the body's immune system to protect against the infection or disease.

Immunization is a proven method of controlling and eliminating life-threatening infectious diseases. It is estimated to prevent two to three million deaths each year. It is one of the most cost-effective health investments with proven strategies to make immunization accessible to even the most vulnerable and hard-to-reach populations. Target groups are well-defined, and immunization can be delivered effectively in the field through mobile teams. No major lifestyle changes are required for vaccination.
