The absence of a nationwide online immunization register means that not all citizens of the United States can access their immunization records online, according to the Center for Disease Control. However, some states maintain local online immunization registries, according to the Immunization Action Coalition.
States such as Texas run a free and confidential immunization registry that allows patients online storage and access to their own immunization record or that of their children, according to the Texas Department of State Health Services. This service is available only if citizens register for the service. Schools, colleges and employers may also offer access to immunization records, according to the Immunization Action Coalition. The CDC also sponsors the Immunization Information Systems program that provides health care professionals and public health officials with a computerized record of vaccinations and immunizations. However, this information may not be accessible to everyone in all states.
