What specific information must be included on a rabies certificate regarding the vaccine itself?

The correct answer emphasizes the importance of including detailed information about the rabies vaccine on the certificate. Specifically, the vaccine product name and expiration date must be documented. This information is crucial because it ensures that the vaccine used is valid, effective, and recognized by health authorities. Having the specific product name helps in tracking the vaccine's effectiveness and any potential issues with specific lots, while the expiration date is vital to confirm that the vaccine is still potent and has not expired.

In contrast, previous medical history is not relevant to the rabies vaccination certificate, as the focus is solely on the vaccination itself. Including only the manufacturer's name does not provide adequate information for verification or tracking purposes. Lastly, stating that nothing is required fails to recognize the legal and health implications associated with rabies vaccinations, making it imperative to include detailed vaccine information on the certificate.
