Vaccine Preventable Disease

A vaccine-preventable disease is an infectious disease for which an effective preventive vaccine exists. If a person acquires a vaccine-preventable disease and dies from it, the death is considered a vaccine-preventable death.

In 2012, the World Health Organization estimated that vaccination prevents 2.5 million deaths each year.With 100% immunization, and 100% efficacy of the vaccines, one out of seven deaths among young children could be prevented, mostly in developing countries, making this an important global health issue. Four diseases were responsible for 98% of vaccine-preventable deaths: measles, Haemophilus influenzae serotype b, pertussis, and neonatal tetanus.

The WHO lists 25 diseases for which vaccines are available worldwide-
