Public Health - Recommendations for Immunizations, Screenings, and Preventive Services - Pharmacist Administration and Required Health Insurance Coverage (The Vax Act)
HB 637 ("The Vax Act") requires Maryland's Secretary of Health to issue science-based recommendations for immunizations, screenings, and preventive services using guidance from major medical organizations like the CDC and American Academy of Pediatrics. It expands pharmacists' authority to administer flu, COVID-19, and emergency vaccines to patients aged 3 and older (previously limited to 18+ for some vaccines) after completing specific training. The bill also mandates that health insurance plans cover these recommended services without cost-sharing for patients. This directly affects pharmacists, health insurers, and Maryland residents seeking preventive care, particularly children and adults needing routine vaccinations.
