More than 5,000 frontline health care workers have been vaccinated in New York City since the shots arrived here on Monday, Mayor Bill de Blasio said Thursday. 

"These numbers are going to grow rapidly with each day as the approach to the vaccine gets refined more each day and more and more people are brought into play,” de Blasio said at his daily briefing.

Of the 5,200 vaccinations, 3,565 have occured since Wednesday morning. 

The vaccinations come as coronavirus rates continue to go up in the city.

According to the mayor, the seven-day positivity rate stands at 6%, above the 5% threshold.

The mayor again warned that restrictions could come after Christmas if the numbers don’t level off.

"The number of cases is too high,” de Blasio said. "The infection levels too high. The number of hospitalizations is too high and unfortunately it's just growing. I don't like restrictions. None of us likes restrictions, but I think we need them sooner rather than later.”

The decision ultimately lies with the state.

To deal with the rise in cases, the city has canceled elective procedures at its 11 public hospitals. 

“We're doing the necessary surgeries and the emergency surgeries, but we have – consistent with the governor's request – we have canceled elective procedures and we do have the extra 25 percent capacity the state has asked us for,” said Dr. Mitchell Katz, the CEO of NYC Health + Hospitals.
