LOS ANGELES — Every shot matters, and Dr. Jerry Abraham is running out of doses of the COVID-19 vaccine.

His clinic, Kedren Health in South Los Angeles, is a hub for health care workers at small, community clinics in L.A.’s poorest neighborhoods.

“Our health care workers who are around COVID-19, they need vaccine today,” Abraham said between inoculations.

Both the Moderna and Pfizer vaccines require two doses to give above 90% immunity, but Kedren is not saving any of their inventory for the second round, opting instead to vaccinate as many health care workers as possible — even if that means Abraham himself has to wait longer for a second shot.

“I will wait if I have to, because we have to get everybody their first dose,” said Abraham, who closely follows guidelines set by L.A. County.

With their first 300 doses into the arms of local health care workers, it’s time to take a trip to get more. In a vaccine rollout that’s been criticized as slow and disorganized, Abraham’s daily phone calls to the county are paying off.

In fact, on a car ride over to pick up more vaccines, Abraham convinced L.A. County to double Kedren’s allotment — from 600 to 1,200 doses of Moderna.

“We don’t want Moderna just sitting in their freezers or their fridges for long periods of time," said Abraham. "That’s not going to do anyone any good.”

Once he’s back at the clinic, the boxes are immediately unpacked, and vaccinations resume.
