Numbers from the state Health Department reveal just 70 percent have finished their vaccine series since the shots were rolled out in December 2020.
Of the five boroughs, Manhattan has the biggest percentage of vaccinated workers with 76 percent having gotten their shots.
Queens has done second best with over two-thirds of health care workers, or 67 percent, being vaccinated.
Though, almost 40 percent of hospital staff in the remaining three boroughs have either resisted the COVID-19 vaccine or not gotten it yet.
Through July 14, 61 percent of workers had been vaccinated in the Bronx, 62 percent in Brooklyn (Kings County), and 64 percent in Staten Island (Richmond County).
Currently, in New York City, at least 69 percent of cases of active COVID cases are of the extremely contagious Delta variant.
Health care workers were among the first people to have the vaccine made available to them in the state back in December 2020.
Only one hospital in the state, NYPresbyterian-Health, has established a necessity for all employees to get vaccinated - giving them until September 1.
According to state data, almost 74 percent of adults in New York state and 70 percent of adults in the city have gotten at least one shot.
This means that health care workers in the state are reaching the city average, though falling behind the rest of the state.
Across the state, 74 percent of healthcare workers are vaccinated.
'It is distressing that so many health care workers are not getting vaccinated,' Richard Gottfried, Health Committee Chairman and representative of Manhattan in the state assembly, told the New York Post.
'It's important to protect themselves, to protect their patients, and to keep the health care system running. They should be setting an example for everyone.'
Hospital workers are at an enhanced risk of catching and transmitting COVID-19 due to their interactions with sick patients at hospitals.
Even when someone themselves does not work around COVID patients, they could still get the virus from others around the hospital.
Because of this, it is essential that healthcare workers get vaccinated, according to the Centers for Disease Control and Prevention (CDC), and is why they were given high priority in the vaccine rollout.
A flood in cases among health care workers can likewise reduce a hospital's ability to heal patients, exacerbating potential problems.
Because of this, many hospital systems around the nation have instituted vaccine mandates, forcing all employees to get the jabs in order to keep their jobs.
