Enforcement of the Biden administration's vaccine-or-test mandate for private companies with more 100 employees will be delayed by a month, officials said.

The Labor Department’s Occupational Safety and Health Administration announced the change Saturday, a day after a federal appeals court lifted a stay on the rule, allowing it to proceed.

Previously, the mandate required companies to enforce masks among unvaccinated employees beginning Dec. 6, and either see proof of vaccination or begin testing workers weekly by Jan. 4.

The new deadlines for compliance are now Jan. 10 and Feb. 9, respectively, OSHA said.

Nearly 22,000 positive COVID-19 test results were reported in New York state in the last 24 hours, according to Gov. Kathy Hochul's office -- breaking a single-day record set the day before.

The 21,908 positive COVID-19 test results are out of 290,930 results reported -- for a 7.53% positivity rate.

Demand for testing also continues to rise, with about 27,000 more people getting tested on Friday.

"This is not like the beginning of the pandemic. We are prepared for the winter surge because we have the tools at our disposal," Hochul said in a statement. "Getting vaccinated, getting the booster and wearing a mask are critical to avoiding getting seriously ill from COVID-19, so don't take a chance."

President Joe Biden will deliver remarks this Tuesday on the country's fight against COVID-19 and "announce new steps" the administration will take amid the growing spread of the omicron variant, White House officials said.

The president will address steps the administration is taking "to help communities in need of assistance, while also issuing a stark warning of what the winter will look like for Americans that choose to remain unvaccinated," White House press secretary Jen Psaki said on Twitter Saturday afternoon.

The speech will come as millions of Americans prepare to travel and gather for the holidays, and as concerns about the omicron variant continue in the U.S. and around the world.

The CDC's advisory committee recommended Thursday that people who have a choice should get an mRNA vaccine, either Pfizer or Moderna, over the single-shot Johnson & Johnson vaccine after a review of new CDC data on rare blood clots linked to J&J.

The vote was unanimous.

The rare blood clots are not a new safety concern and the vaccine has already become far less common in the U.S. after it was given an FDA warning label about the clotting condition. But more data that confirmed a slightly higher rate of clotting cases and deaths than was previously reported caused the CDC and FDA to take another look at the data this week.

The CDC has confirmed nine deaths and 54 cases from the severe clotting event, thrombosis with thrombocytopenia.

There could also be more cases and deaths because TSS is under-diagnosed and could be underreported, the CDC said.

The clotting is more common among women in their 30s and 40s but has been seen in adult men and women of all ages.

The experts said J&J should not be taken off the shelves and is still far more beneficial than not getting any vaccine at all.
