(CNN) — Jessica Desfosses shared the final heartrending text messages she exchanged with her police officer husband in the days before he died from COVID-19.
"Commercial just came on tv a casket saying take Covid seriously... 0 consideration for those of us fighting for every breath," Stephen Desfosses wrote in a series of exchanges that began last Christmas Eve as his condition steadily deteriorated in a Massachusetts hospital.
"Your husband is going to (be) changed forever no matter what happens...my life has flashed before my eyes and man it's scary," he wrote in another message, which his wife posted to Facebook last summer.
Det. Sgt. Stephen Desfosses, 52, a veteran of more than 30 years with the Norton Police Department, died on Jan. 13. He was one of at least 231 officers who died of COVID-19 this year, according to the Officer Down Memorial Page (ODMP).
There were 245 law enforcement deaths from COVID-19 in 2020, according to ODMP.
The coronavirus has become the leading cause of death for officers despite law enforcement being among the first groups eligible to receive the vaccine at the end of 2020. The total stands at 476 COVID-19-related deaths since the start of the pandemic, compared to 94 from gunfire in the same period.
"If you are serious about your commitment to protect the public ... and if you are serious about your personal commitments to your family, then that should be enough," Jessica Desfosses said in a plea for police officers to get vaccinated.
Her appeal comes as law enforcement officers and their unions across the country have resisted vaccine mandates despite the Delta variant-fueled resurgence of COVID-19 and effectiveness of the shots in preventing severe cases and death.
Reasons cited for the vaccine resistance among law enforcement officers range from disinformation to distrust in the science of the vaccines.
The debate mirrors growing tension nationally between unions and employers as cities and businesses seek to enforce vaccine mandates.
"You're not drafted into this job. This is something you volunteer for," said Charles Ramsey, a former Washington, D.C., police chief and CNN law enforcement analyst. "You understand when you take the job it's going to require some sacrifice on your part in a lot of different ways."
Police unions challenge mandates
In Chicago, up to half the rank-and-file officers in the nation's second largest police department face being placed on unpaid leave as their union and Mayor Lori Lightfoot clash over a city requirement that officers disclose their vaccine status.
Lightfoot on Friday accused police union president John Catanzara of trying to "induce an insurrection" by telling officers to ignore a deadline to report vaccine status.
The city filed a complaint alleging the union was "encouraging a work stoppage or strike." A Cook County Circuit judge ruled Friday night that Catanzara should not make public statements encouraging members not to comply with the vaccination policy.
Catanzara "has never engaged in, supported, or encouraged a work stoppage," according to a union statement on Friday.
Chicago officers had a deadline of midnight Thursday to disclose their vaccine status or be placed on unpaid leave, Catanzara said earlier this week.
Lightfoot said the city would take the weekend to check with officers who haven't complied. She said officers should report for duty until they're told by supervisors that they've been placed on leave.
Earlier this month, the former president of the union from 2014 to 2017 died of COVID-19.
In Miami, officers are resisting a vaccine mandate. In Pittsburgh, the police chief sent out emails encouraging officers to protect themselves as the Delta variant sent COVID-19 cases soaring.
In Seattle, the police department had "all non-patrol sworn personnel, detectives, training, support staff" ready to respond to emergency calls ahead of Monday's vaccination mandate deadline, said Sgt. Randy Huserik, a spokesman.
The Seattle mayor's office said nearly 140 officers were unvaccinated or hadn't sought an exemption. Huserik said about 320 officers had already left the force since the beginning of 2020.
Seattle could begin the process of separating officers from the department after the deadline, according to Mike Sloan, police union president.
"If we lose what appears to be over 300 people because of this mandate, this public safety crisis we're experiencing will look like child's play," Sloan said.
Across the U.S., law enforcement leaders have pleaded with officers who remain hesitant to get the shot. Still, many unions and their member officers continue to push back.
"It's a right to obviously get vaccinated. It's an individual right and I firmly still believe in that," said Dan Yancey, chief of the Owasso Police Department in Oklahoma. "But I would certainly encourage people to do that."
The national police union is encouraging vaccinations but opposes mandates.
Catanzara has framed the issue as a labor dispute.
"We are going to keep fighting this mandate and this dictatorship," said Catanzara, president of the Chicago Fraternal Order of Police, echoing the sentiments of union leaders around the country.
"You would think that there is no crime in this city to worry about. You would think that there is no murder, no robberies, no guns being fired."
Jessica Desfosses wants to turn her unspeakable loss into an opportunity to save lives.
"It's absolutely as bad as you would imagine to be raising two small girls without their dad," she said of her late husband, Stephen, who "wanted to be first in line for that vaccine" but never got the chance.
"And if he had had the choice to give himself that extra protection so he could continue to serve the public and still come home to his family, he absolutely would have done it."
