The survey drew a response from about 25 percent of the roughly 8,200 members. It asked, "Will you get the COVID-19 Vaccine from Pfizer when the Department makes it available?"

Of the over 2,000 who responded to the survey, some 1,100, or nearly 55 percent, said they would not get the vaccine, while 929 respondents indicated otherwise, according to Uniformed Firefighters Association President Andrew Ansbro:

The UFA represents only FDNY firefighters, not the department's emergency medical services or officers. However, firefighters are included in medical responses, including to Covid-19 calls, according to Ansbro.

Ansbro told CNN he will "definitely" get the vaccine and hopes more members will as well.

"I will encourage them to get it, but at the end of the day, it is a hundred percent their own choice," he told the outlet.

The survey comes as researchers found first responders, including "New York City emergency medical service providers and firefighters," were 15 times more likely to contract the virus than other residents during the start of the pandemic:

Nearly 14,300 FDNY workers employed during the height of the pandemic were studied by researchers, including 3,501 EMS workers and 10,789 firefighters.

Michael Weiden, an FDNY medial officer and New York University Medical School professor, and his colleagues found 5,175 confirmed or suspected coronavirus cases among FDNY workers between the beginning of March to the end of May.
