What best describes the walk-in model of vaccine administration?

The walk-in model of vaccine administration is characterized by allowing patients to receive vaccines without the need for an appointment. By incorporating vaccinations into the workflow similarly to prescriptions, patients can come in and receive their vaccinations on a flexible basis. This model aims to eliminate barriers to vaccine access, such as scheduling conflicts or the need for prior arrangements. It encourages higher vaccination rates by making the process more convenient for individuals who may not have the time or ability to plan ahead.

Options that involve scheduling in advance or administering vaccines at large events are not consistent with the walk-in model, as they impose limitations on accessibility and spontaneity. Instead, the walk-in model emphasizes ease of access and encourages patient participation in their own healthcare. While pharmacists providing vaccines as part of broader patient care services aligns with comprehensive care, it does not specifically capture the flexibility and accessibility inherent in the walk-in approach.
