LOS ANGELES, Calif.–Thousands of people without medical insurance lined up outside Los Angeles Memorial Sports Arena today to obtain admission wristbands for a four-day free health clinic scheduled at the venue later this week.

The clinic is expected to provide free medical, dental and vision care for as many as 4,800 uninsured people between Thursday and Sunday, according to the event sponsor, Care Harbor. The clinic will run from 7 a.m. to 5 p.m. each day.

Some people began lining up as early as Friday to ensure they obtain a wristband, which will be required for admission to the clinic. Distribution of the wristbands is expected to begin at 1 p.m.

Care Harbor has run several similar clinics in the Los Angeles area over the past few years. A four-day event last October at the Sports Arena was attended by about 5,000 people.

Medical practitioners who take part in the event volunteer their time and services. Care Harbor officials said they are still looking for additional volunteers for this week’s clinic.

Medical services offered at the clinic will include immunizations, women’s health screenings, acupuncture and chiropractic care. There will also be dental cleanings, fillings and extractions and eye exams, according to Care Harbor.
