Health experts say any strategy of letting first responders be exposed to the coronavirus would be misguided and even dangerous.
Arriola said that he raised a hypothetical question about first responders and immunity. Arriola said he was referring to the U.K.’s course of action, which early on was different from many other countries.
U.K. officials made some statements suggesting that they would avoid lockdowns and hope to achieve herd immunity. Their statements created confusion.
A Miami Beach city commissioner created a stir when he suggested that first responders should try to catch coronavirus so that they will develop immunity.
"Some doctors have told me yes," Arriola said. "To the extent that that is true, might we start thinking about, dangerous but bold ..."
"Chicken pox," someone else in the commission meeting said.
Arriola continued: " — it’s like chicken pox, thank you — with our first responders voluntarily taking one for the team, going through the two weeks. Guys, we have to be serious about this, and then developing the immunity. It’s our job to think boldly."
Arriola told PolitiFact that he wasn’t proposing that first responders should get the virus but raised a hypothetical question and was trying to "think out of the box." He tweeted that his comments related to the approach the U.K. had taken to coronavirus.
Health officials told us that any strategy of letting first responders be exposed to the coronavirus would be misguided and even dangerous.
Police, firefighters and other first responders don’t have the option of working from home and must continue to interact with the public. Medical experts told us it’s a bad idea to try to let these workers become infected.
First "such a plan would not be possible by any established or ethical method" said Dr. Myron Cohen, an expert in Immunology, and Epidemiology at the University of North Carolina School of Medicine.
Second, it’s not clear if COVID-19 will leave those who recover from the disease immune to it in the future. Dr. Melissa Brown, a professor of microbiology/immunology at Northwestern, previously told PolitiFact that long-lasting immunity is not likely because similar respiratory infections will only leave the body with short-lived immunity.
Third, even among first responders who are relatively young, it’s possible some could get a severe case, including any who have underlying conditions.
"It’s not a completely benign disease," said David Hamer, an expert on infectious diseases at Boston University.
Stephen S. Morse, Columbia University professor of epidemiology, said a more effective strategy would be for first responders to use personal protective equipment and test them all periodically.
"The problem is that testing is in short supply, and uses valuable resources, but I think it would be far more practical," he said.
U.K. officials created a flap over theories about herd immunity and their initial response to coronavirus, which differed from some other European countries.
"Herd immunity" or community immunity occurs when a high percentage of a community is immune to a disease — either through vaccines or prior illness — reducing the spread of a disease. It’s not clear what percentage of the population needs to develop immunity after infection or future immunization, but it could be in the range of 60-70%. Since there is no vaccine yet, a strategy of encouraging illness poses risks.
While Italy, France and Spain instituted lockdowns, Prime Minister Boris Johnson initially called for "not taking as many draconian measures" and said that he would not be closing schools or cancelling large events.
Britain’s chief scientific adviser Sir Patrick Vallance said on March 13, "Our aim is to try and reduce the peak, broaden the peak, not suppress it completely. Also, because the vast majority of people get a mild illness, to build up some kind of herd immunity so more people are immune to this disease."
Dr. William Hanage, an expert on epidemiology of infectious disease at Harvard, wrote in an op-ed for The Guardian that he thought Britain’s plan was "satire."
"The U.K. should not be trying to create herd immunity, that will take care of itself," he wrote. "Policy should be directed at slowing the outbreak to a (more) manageable rate."
Medical experts in the U.K. told The Atlantic that it wasn’t actually the goal of U.K. officials to spread the coronavirus to lead to herd immunity, but that they botched public communication. The U.K.’s written plan on March 3 didn’t mention herd immunity at all.
The U.K. changed course following the March 16 release of a study by the Imperial College COVID-19 Response Team. Experts outlined two different strategies: mitigation, which aims to slow but not necessarily stop the epidemic, and suppression, which aims to reverse epidemic growth.
The experts concluded that mitigation might reduce deaths, but would still likely result in hundreds of thousands of deaths and overwhelm intensive care units. Experts concluded that suppression is the "only viable strategy at the current time. "
On March 16, Johnson announced new measures including recommendations that everyone should work from home if possible and avoid crowded gatherings, including at pubs and restaurants. Johnson said that those with underlying conditions and the elderly should stay at home.
"Herd immunity is not part of our action plan but is a natural by-product of an epidemic," said Alex Gore, a spokesman for the U.K.’s Department of Health and Social Care. "Every measure that we have or will introduce will be based on the best scientific evidence."
