Vintage Health and Immunization Record card dated 6-27-79 issued by Tri-County District Health Service

Health and immunization record cards became standardized in the United States during the mid-20th century as public health departments sought to track vaccination compliance and maintain medical records. These cards were issued by local health departments and served as official documentation of an individual's immunization history, particularly important for school enrollment and employment requirements. Such cards represent an important piece of American public health history, documenting the era when widespread vaccination programs were being implemented across the country. These records are valued by genealogists, medical historians, and ephemera collectors who appreciate their role in documenting personal and public health history. The cards serve as tangible reminders of public health initiatives and provide insights into medical practices of the late 20th century, making them interesting artifacts for those studying the evolution of healthcare documentation and disease prevention efforts.
