First shipment of Pfizer vaccines arrive, inoculations set to begin | Jonathan Wosen

In total, San Diego County will initially receive 28,275 doses of vaccine. Each dose will be given to hospital health care workers at highest risk of exposure to the coronavirus — including doctors, nurses, custodians and security staff who are regularly in contact with COVID-19 patients. Because Pfizer’s vaccine requires two doses, those who get the vaccine will need a booster shot about three weeks later when another vaccine shipment arrives.
