Equipped with basic medical equipment, medicines, and staffed by an experienced doctor, a pharmacist and a social worker, these vans provide free health services, screening and health education to the doorsteps of under-privileged people. The MMUs have been doing this for more than 15 years- and in that time have provided 2,00,000 annual treatments to patients who are often missed by our health care systems: the uninsured, underinsured and undocumented, vulnerable groups.
