What should be documented when administering a vaccine?

When administering a vaccine, it is essential to document key information to ensure patient safety, maintain accurate medical records, and comply with regulatory requirements. The correct choice encompasses critical details that should be recorded:

• The vaccine given: This specifies which vaccine was administered, which is vital for tracking immunizations and understanding a patient's vaccination history.

• The date of administration: This indicates when the vaccine was given, helping to manage the timing of subsequent doses if required, and ensuring compliance with vaccination schedules.

• The lot number: This information is crucial for traceability, especially in the event of any adverse reactions or product recalls, as it allows health authorities to track the specific batch of vaccine that was used.

• The expiration date: Documenting this prevents the administration of expired vaccines, which could lead to ineffective immunization and safety issues for the patient.

While personal information, route of administration, and manufacturer details are important, they are not as comprehensive in documenting the key aspects of vaccine administration, which is why the specified details in the correct choice represent best practices in immunization documentation.
