Supervisor Nathan Fletcher said Wednesday that San Diego County can now administer 33,000 vaccine doses daily, but continued shortages are hampering efforts.

He said the supply of the Moderna vaccine, which is used at the Petco Park Vaccination Super Station, has been “consistently erratic and consistently unpredictable.”

“We have a shortage of vaccines. Many of our sites are struggling. They are working as hard as they can to try and honor those second dose appointments,” said Fletcher at the county’s weekly briefing on the pandemic.

As of Wednesday, the county had received a total of 1,067,675 doses and had 114,427 on hand to be administered. However, over 300,000 people are currently in line for a second dose.

Fletcher said he had no answer for why the Moderna supply was particularly problematic, though winter storms shut down the company’s plant in Massachusetts last month.

“We continue to have challenges in not enough vaccines arriving,” Fletcher said. “But we remain hopeful that the supply will increase.”

County officials said they are anxiously awaiting the first shipments of the new Johnson & Johnson vaccine, which requires only one dose.

“We are going to plug it in for all of our vaccination sites,” said Dr. Wilma Wooten, the county’s public health officer.

She said the J&J vaccine would also be used with hard-to-reach groups such as agricultural workers.
