Mollen Immunization Clinics of North America

Mollen Immunization Clinics of North America was a prominent provider of mass-immunization and community health services in the United States. The company specialized in the administration of seasonal influenza vaccines, as well as other adult immunizations and health screenings, through partnerships with major retailers like Walmart, Sam's Club, and Rite Aid. At its height, Mollen operated thousands of clinics annually across all 50 states, making it one of the largest private flu shot providers in the country. Following legal settlements related to billing practices and subsequent financial difficulties, the company's assets were acquired by Passport Health in 2014.
