LOS ANGELES (CNS) — The pool of residents eligible for COVID-19 vaccinations vastly expanded in Los Angeles County Monday, with teachers and other essential workers added to the list of those who qualify for vaccines.

Workers in education and child care, food and agriculture, and law enforcement and emergency services all became eligible for shots — but health officials said those workers will have to be patient as vaccine supplies remain limited and staff are being trained to ensure only eligible people receive shots. The newly eligible workers represent anywhere from 1.2 million to 1.7 million people.

"Therefore, it will take considerable time to vaccinate these groups, unless vaccine supply significantly increases," said Dr. Paul Simon, chief science officer for the county Department of Public Health. "We urge the public's patience as we work through this process as quickly as possible."

Residents age 65 and older also remain eligible for the shots, and the county's public health director said last week roughly 700,000 of them are yet to receive their first dose. Health care workers are also still being vaccinated, along with residents and staff of long-term care and nursing facilities.

On Friday, Simon said L.A. County expects to receive a total of 269,000 doses this week, up from 211,000 last week. With the county setting aside many doses for people who are due for the second shot of the two-dose regimen, a total of 103,000 doses will be available this week for the three sectors of workers and for people aged 65 and over.

Of those 103,000 doses:

• 35.8% will be allocated to people 65 and over
• 27.6% will go toward food and agriculture workers, including grocery workers
• 30.3% will be allocated for the education/child care sector
• 6.2% will be directed to emergency services and law enforcement.

"This allocation is proportional to the size of the population in each sector as well as the size of the unvaccinated 65-plus population in the county," he said.

Workers in each of the sectors will also have to prove they are eligible to receive a vaccine. Full details are listed on the county's website.

"For each sector, workers will be required to show proof of their identity, with a photo ID, and proof that they reside or work in L.A. County," Simon said. "A government ID is not required, just some identification with a photo. Demonstrating that they work in one of the eligible sectors will also be required, and there are a number of ways to provide documentation."

He said some of the ways people can provide documentation is a employee badge with the names of the worker and the employer, a pay stub with an address, a California food handler card or some other type of official license.

Simon said the county is well aware of issues with people jumping the line to get vaccinated and sometimes-varying identification demands made by workers at vaccination sites. But he said efforts are being made to eliminate those issues.

"We are training our staff as I speak," he said Friday. "And we will continue that over the weekend. We do anticipate, though, that next week will be a learning process. We're hoping it'll go as smoothly as possible, but I'm sure there will be some mid-course corrections next week if we see any issues of concern."

To help expedite vaccinations for the new groups, the county's five large-scale vaccinations sites — Pomona Fairplex, the Forum, Cal State Northridge, county Office of Education in Downey, and Six Flags Magic Mountain — will reserve shots for select workers on different days this week.

On Tuesday and Thursday, only food and agriculture workers will be vaccinated at the sites, while Wednesday will be reserved for emergency services workers, Saturday for early child care and education workers, and Sunday for staff at independent schools.

Much attention during the expansion of the vaccination effort is likely to be placed on the speed of inoculating teachers, with pressure mounting to reopen school campuses for in-person instruction. Many teachers' unions, including the one representing Los Angeles Unified School District educators, are pushing for school staff to be vaccinated before in-person classes resume.

Gov. Gavin Newsom has mandated that 10% of all vaccine supply received in the state be immediately set aside for teachers, child care workers and other school staff. But dividing the education allocation among the 80 school districts in Los Angeles County will be a weekly challenge.

To address the issue, the county has devised a complex formula aimed at doling out the vaccine in an equitable manner.

Of the doses allocated to the education sector each week, 9% will be automatically directed to private schools in the county, reflecting the percentage of county students they serve.

The 80 individual school districts in the county — excluding those in Long Beach and Pasadena, which have their own health departments — will be divided into five groups. Remaining available doses will be divided among those groups based on a formula that evaluates factors of overall student enrollment; the percentage of students living in poverty — based on those eligible for free or reduced-price lunches; COVID case rates in each community; and whether schools have already been providing in-person services for higher-need students.

The formula means the LAUSD — the second-largest school district in the nation — will likely receive about 40% of available education-sector doses each week.

To help expedite the teacher vaccines, the LAUSD opened a large-scale vaccination site Monday at SoFi Stadium in Inglewood, a site reserved solely for education workers. Superintendent Austin Beutner said the site is "the largest vaccination site in the country dedicated to school staff." He said the district will try to initially target teachers and staff for the youngest students.

"There are more than 86,000 people who work in traditional and charter schools in Los Angeles Unified and our initial focus will be to vaccinate school staff who are currently working at school sites and all who are involved in preschool and elementary school," Beutner said.

He has said previously that the district will need to vaccinate 25,000 people to get elementary schools open. He has targeted April 9 for a return to in-person elementary school instruction, but the teachers' union, United Teachers Los Angeles, has yet to sign off on that date, insisting that all educators and staff be vaccinated and calling for a delay until the local transmission rate drops even further.

Newsom and state legislative leaders announced a proposed deal Monday that would provide financial incentives for districts to resume in-person classes for pre-kindergarten through second grade by April 1, but LAUSD is unlikely to meet that date.

The state has authorized shots beginning March 15 for anyone age 16 and over with an underlying health condition that puts them at higher risk for severe illness or death from COVID.

Public Health Director Barbara Ferrer said Wednesday it's still unclear whether the county will actually expand eligibility to that group on March 15. She said the county is waiting for more details from the state about how that expansion will work, and whether the county can realistically offer those shots given continued limited vaccine supply.
