PneumoRecs VaxAdvisor provides patient-specific pneumococcal vaccination guidance consistent with the pneumococcal vaccination recommendations of the Advisory Committee on Immunization Practices. Vaccination providers enter a patient’s age and respond to prompts about the patient’s pneumococcal vaccination history and underlying medical conditions. The app then displays patient-specific pneumococcal vaccination recommendations consistent with the recommended U.S. immunization schedule.
