What does a pharmacist require to administer influenza vaccines?

To administer influenza vaccines, a pharmacist typically requires a standing order from a prescriber. This is a written protocol that allows the pharmacist to administer vaccines according to specific guidelines without needing each individual prescription. While some locations may have regulations regarding consent or insurance information, the crucial requirement is the standing order, which is formulated by a licensed healthcare provider and establishes the authority for pharmacists to proceed with vaccinations.

The other choices focus on aspects that are secondary to the primary requirement of a standing order. For instance, written consent from the patient may be necessary but does not replace the need for a standing order. Similarly, patient insurance details may be relevant for billing purposes but are not a requirement for administering the vaccine itself. Approval by the commissioner of health is not typically necessary unless there are specific public health guidelines in effect, which is a different scenario compared to the standard practice for vaccine administration.
