Immunization

Immunization is one of the most cost-effective health investments, with proven strategies that make it accessible to even the most hard-to-reach and vulnerable populations. It is actually the process whereby a person is made immune or resistant to an infectious disease, typically by the administration of a vaccine. Immunizations are definitely less risky and an easier way to become immune to a particular disease than risking a milder form of the disease itself. It is a proven tool for controlling and eliminating life-threatening infectious diseases and is estimated to avert between 2 and 3 million deaths each year.
