Which provider factor is associated with low vaccination rates in adults?

The factor associated with low vaccination rates in adults is the lack of effective reminder or recall systems. These systems play a crucial role in ensuring that patients are reminded about upcoming vaccinations or are prompted to receive vaccinations they may have overlooked. When providers do not have a mechanism in place to regularly remind patients about their vaccination needs, individuals may not prioritize or remember to get vaccinated, leading to lower overall vaccination rates within the adult population.

Additionally, effective reminder systems can help overcome barriers such as forgetfulness or lack of awareness about the importance of vaccines, ultimately facilitating better adherence to vaccination schedules. By contrast, while factors such as the ability to bill insurance, familiarity with the adult vaccination schedule, and state regulations can impact vaccine delivery, the absence of structured reminder systems has a direct and significant impact on patient compliance with vaccination recommendations.
