Which type of record helps track immunizations in a patient?

The type of record that helps track immunizations in a patient is immunization records. These records specifically document the vaccines a patient has received, including details such as the type of vaccine, the date it was administered, and any necessary follow-up doses. This information is crucial for ensuring that patients are up to date with their immunizations, which is essential for preventing disease outbreaks and maintaining public health.

In contrast, medical history forms provide a broad overview of a patient's past health events and conditions but do not specifically track immunizations. Patient consent documents pertain to permissions granted for medical procedures or sharing information, without focusing on vaccination status. Billing records are related to payment information for medical services rendered and do not contain details about immunizations. Thus, immunization records stand out as the specific documentation needed for monitoring a patient's vaccination history.
