More than 35.6% of the Chicago Police department — 4,543 employees — are in jeopardy of being disciplined and eventually fired for failing to disclose their vaccination status to the city. 

An advisory panel with the Food and Drug Administration is recommending that the agency authorize COVID-19 booster shots for Moderna and Johnson & Johnson. However, in Latino communities, rates of initial vaccination are still lagging.

A Cook County judge ordered Police Union President John Catanzara on Friday to stop making public statements on social media or in the media that encourage police officers not to comply with the city’s COVID-19 vaccine mandate until a hearing Oct. 25.

U.S. health advisers endorsed a booster of Johnson & Johnson’s COVID-19 vaccine Friday, citing growing worry that Americans who got the single-dose shot aren’t as protected as those given two-dose brands.

Police and other first responders — who come in close physical contact with Chicagoans — must be vaccinated to protect the health and safety of Chicagoans, Mayor Lori Lightfoot said. 

Fraternal Order of Police President John Catanzara's actions and rhetoric "threatens the health and safety of Chicago’s residents and first responders," Mayor Lori Lightfoot said.

The panel of outside advisers to the Food and Drug Administration voted unanimously to recommend a booster shot for seniors, as well as younger adults with other health problems, jobs or living situations that put them at increased risk from COVID-19.

In a video posted online Tuesday, Fraternal Order of Police President John Catanzara vowed to take Mayor Lori Lightfoot’s administration to court if it tries to enforce a mandate, which requires city workers to report their vaccine status by the end of the work week. 

Chicago Public Schools CEO Pedro Martinez said those staffers who are not fully vaccinated by Friday’s deadline must consent to weekly testing, but will not be immediately barred from working, as had previously been threatened.

The Food and Drug Administration is wrestling with whether and when to offer another dose of the single-shot Johnson & Johnson COVID-19 vaccine, while a new study out Wednesday raises the prospect that using a different brand as the booster might work better.

With many Americans who got Pfizer vaccinations already rolling up their sleeves for a booster shot, millions of others who received the Moderna or Johnson & Johnson vaccine wait anxiously to learn when it's their turn.

Airline employees refusing COVID-19 vaccines could lose their jobs. What impact could that have on the airline industry?

But with a week to go until her declared deadline, Mayor Lori Lightfoot stepped back and said she would not discipline unvaccinated employees. 

President Joe Biden on Thursday championed COVID-19 vaccination requirements, determined that the roughly 67 million unvaccinated American adults must get the shot even as he acknowledged that mandates weren’t his “first instinct.”

Pfizer asked the U.S. government Thursday to allow use of its COVID-19 vaccine in children ages 5 to 11 – and if regulators agree, shots could begin within a matter of weeks.

Pedro Martinez, Chicago Public Schools’ new CEO, said Thursday the district will provide more COVID-19 testing and work harder to keep families in the loop on case information amid confusion and criticism through the first month of the school year.
