How long must immunization records be maintained?

Immunization records must be maintained for three years. This requirement ensures that individuals have access to their immunization history, which is important for public health, continuity of care, and for verifying vaccination status when necessary, such as for school enrollment or employment in healthcare settings. Maintaining these records for a minimum of three years allows for sufficient tracking of immunizations and supports public health initiatives. This timeframe aligns with both federal guidelines and standard practices in the pharmaceutical and healthcare fields, ensuring that patient information is kept accurate and easily accessible over an extended period while balancing the need for record retention with the realities of storage and information management.
