Immunizations, or vaccinations, are essential for children and adults. They protect against illnesses such as measles, mumps, rubella, hepatitis B, polio, tetanus and many others. Immunization is the process whereby a person is made immune or resistant to an infectious disease, typically by the administration of a vaccine. Vaccines stimulate the body’s own immune system to protect the person against subsequent infection or disease.
Immunization has been proven for controlling and eliminating life-threatening infectious diseases and is estimated to avert between 2 and 3 million deaths each year. (Source: WHO)
