Hundreds of immunocompromised Marin County residents get third shot of COVID vaccine

The county, in partnership with Safeway, was prepared to vaccinated 1,300 people throughout the day. But the event wasn’t open to everyone. The FDA has only authorized a third shot for people who weren’t able to build a sufficient antibody response after the first two shots. KTVU's Amanda Quintana reports from Marin.
