Late last year, firefighters were the first city workers given access to the shots. After an initial burst of activity, the number showing up to get the vaccine has plummeted.

This past week, only 143 firefighters visited one of the department's vaccination centers, according to data released by the city Friday night. So far, 1,944 of the agency's just under 3,400 members have been inoculated, leaving 4 in 10 vulnerable to the highly infectious coronavirus.

The reluctance of L.A. firefighters adds to the list of healthcare workers in the state who are declining to take the vaccine, a trend that health experts say could have serious public health implications.

The Times added that L.A. Mayor Eric Garcetti is considering making vaccination mandatory for firefighters and others on the front lines of the fight against an ongoing surge in COVID-19 cases.
