Chicago restaurants and bars have been prohibited from serving patrons indoors since Oct. 30, when a sustained and grave surge of coronavirus cases threatened to overwhelm the city and state’s hospitals and health care system.

New mass vaccination sites will open on Friday at Olive Harvey City College, on Tuesday at Kennedy-King City College and on Wednesday at Truman City College, officials announced.

City health officials will allow Chicagoans 65 and older to be vaccinated against COVID-19 starting next week — if there are doses available after health care workers and residents of long-term care facilities are vaccinated, the city’s top doctor told aldermen Wednesday.

The nation’s overall death toll from COVID-19 has eclipsed 380,000, according to Johns Hopkins University, and is closing in fast on the number of Americans killed in World War II, or about 407,000. Confirmed infections have topped 22.8 million.

Investigators with the city’s Department of Business Affairs and Consumer Protection conducted 105 investigations from Thursday through Sunday.

The Trump administration on Tuesday instructed states to begin vaccinating Americans over age 65 for COVID-19, as well as those with chronic medical conditions. We discuss Chicago’s rollout with an infectious disease specialist.

The short answer: Yes. Regardless of previous infection, the U.S. Centers for Disease Control and Prevention says people should plan on getting vaccinated when it’s their turn.

“Most people survive this illness but some don’t,” Illinois’ top doctor said before receiving her first dose of Pfizer’s COVID-19 vaccine. “I don’t want to gamble with my life and I don’t want anyone else to gamble with theirs.”

Under the new system, which will take effect Friday, a state will be placed in one of two categories — orange or yellow — based on whether it has more than 15 new COVID-19 cases per day, per 100,000 population, officials said.

Illinois U.S. Rep. Brad Schneider is the third Democratic member of the House who has tested positive for COVID-19 after being forced to go into lockdown during last week’s violent siege at the U.S. Capitol.

Dozens of aldermen peppered school and health officials with questions Monday about the effort underway to reopen Chicago Public Schools for in-person learning after a 300-day closure prompted by the coronavirus pandemic.

The U.S. is entering the second month of the biggest vaccination effort in history with a major expansion of the campaign, opening football stadiums, major league ballparks, fairgrounds and convention centers to inoculate a larger and more diverse pool of people.

Mayor Lori Lightfoot on Sunday extended the advisory that urges Chicagoans to stay home in an effort to stop the spread of COVID-19 — meaning it will be in effect for 12 days after the first Chicago Public Schools students go back to in-person class.

President-elect Biden’s plan is not about cutting two-dose vaccines in half, a strategy that top government scientists recommend against. Instead, it would accelerate shipment of first doses and use the levers of government power to provide required second doses in a timely manner.

Dr. Marina Del Rios was the first person in Chicago to be fully vaccinated against COVID-19 after receiving her second dose of the Pfizer vaccine Tuesday. “I felt reassured that this was safe and efficacious,” she said.

Gov. J.B. Pritzker said on Twitter that the benchmark was a “tragic milestone” that was “heart-wrenching.”
