But there's a catch: no local health departments are going to follow the state's guidelines because there aren't enough vaccine doses currently available.
How much protection does the COVID-19 vaccine offer? How vaccinated people should approach seeing others
Multiple county health departments say it could be weeks before they're able to expand vaccine eligibility to people younger than 65 with underlying conditions, despite assurances from the state that supply will soon increase substantially.
Gov. JB Pritzker said federal deliveries to Illinois will increase to 100,000 daily doses by mid-March - nearly double what the state is currently managing.
"I encourage all of our local health departments, especially those not yet on pace for the expansion, to move as quickly as possible to broaden our reach in light of ever-increasing federal supply," Pritzker said.
But in Lake County, less than one third of people 65 and older has been vaccinated.
The county is adhering to CDC guidelines that say 60 to 70 percent of people in a current phase should be vaccinated before expansion, unless supply outpaces demand.
"We are seeing great demand, and I can tell you that every day I get emails from those 65 and above that are clamoring for their vaccination," said Mark Pfister, executive director, Lake County Health Dept.
In fact, on the eve of the state's 1B expansion, not one area county health department has announced when that move will happen.
"Really watching to see what the situation looks like in the next four to six weeks and then making a decision about how and when to expand to the next group," said Chris Hoff, DuPage County Health Dept.
In Chicago, it could be late March.
"I don't want to create expectations that we simply can't fulfill particularly when we still must focus on our elderly," Mayor Lori Lightfoot said.
There may still be some providers, including pharmacies, in our area that expand eligibility, but they have to receive vaccine directly from the state or federal government, rather than those counties.
