Immunizations (or vaccinations) prevent the occurrence of disease in the individuals that receive them. They boost the body’s immune system by creating antibodies in order to prevent individuals from becoming infected. Most vaccines contain the single virus or bacteria, also known as antigens that is either weakened or dead. This allows the body’s immune system to create antibodies against the particular virus. Antibodies trap and kill the virus inside the body. There are two ways that the immune system can create antibodies: contracting the disease or by receiving the proper immunizations. Receiving proper immunizations is a safer option because it allows your immune system to create antibodies without actually having to suffer from the disease and any related symptoms. When an immunized individual is exposed to the vaccine preventable virus or bacteria, he or she will not become infected or will have a less severe reaction.

Increases in both individual and community awareness and knowledge of immunizations combined with ensuring access to needed vaccines can result in changed attitudes and community norms as well as improved adherence to immunization recommendations. In addition to specific intervention strategies, tools and resources to increase immunizations in order to prevent complications are also included in Intervention MICA. 

Several resources are available to provide more information regarding immunizations.
