When federal well being officers stated on Thursday that totally vaccinated Americans now not wanted to put on masks in most locations, it got here as a shock to many individuals in public well being. It additionally was a stark distinction with the views of a massive majority of epidemiologists surveyed in the final two weeks by The New York Times.
In the casual survey, 80 % stated they thought Americans would want to put on masks in public indoor locations for at least one other 12 months. Just 5 % stated folks would now not must put on masks indoors by this summer time.
In massive crowds open air, like at a live performance or protest, 88 % of the epidemiologists stated it was crucial even for totally vaccinated folks to put on masks.
“Unless the vaccination rates increase to 80 or 90 percent over the next few months, we should wear masks in large public indoor settings,” stated Vivian Towe, a program officer at the Patient-Centered Outcomes Research Institute.
The responses got here from 723 epidemiologists, submitted between April 28 and May 10, earlier than the brand new steering from the Centers for Disease Control and Prevention. The survey requested epidemiologists about being open air in teams of numerous sizes, and about being indoors with folks whose vaccination standing was unknown. The conditions had been per the brand new steering, which governs habits in public locations, regardless of dimension, the place it’s unimaginable to know the vaccine standing of others.
Federal well being officers have already stated that vaccinated folks could be indoors with different vaccinated folks, and epidemiologists principally agreed. But the C.D.C.’s new steering stated masks had been now not crucial for totally vaccinated folks regardless of the scale of the gathering and whether or not it was indoors or exterior, besides in sure conditions, like in a physician’s workplace or on public transit.
Epidemiologists are, on the entire, very cautious with regards to Covid-19, by nature of their coaching in understanding threat and stopping the unfold of infectious illness. Nearly three-quarters described themselves as risk-averse, and they’re prone to have been in a position to do business from home over the previous 12 months, not like many Americans. But in addition they have the identical coaching as many of the scientists at the C.D.C. who devised the brand new coverage, and about one-third of the survey respondents work in authorities, principally at the state stage.
They acknowledged that many Americans wouldn’t wish to proceed to put on masks — and that many have already stopped.
Wearing masks “will be a need, which is a very different question than how long will it continue to occur,” stated Sophia Ok., an epidemiologist at the Great Lakes Inter-Tribal Council. “I expect that most people will refuse to wear masks, even in public, by the end of 2021, whether there is still a pandemic or not.”
Many epidemiologists echoed the C.D.C. in saying that so long as folks had been totally vaccinated, they might collect with out precautions. But the C.D.C. went additional than the epidemiologists by giving the OK for vaccinated folks to cease masking in teams with an unknown quantity of unvaccinated folks.

“It is either you trust the vaccine, or you do not,” stated Kristin Harrington, an epidemiology Ph.D. pupil at Emory. “And if we trust the vaccine, that means an unlimited number of vaccinated individuals should be allowed to gather together.”
Others acknowledged that coverage choices are based mostly on many targets, equivalent to invigorating the economic system and incentivizing folks to get vaccinated.
Yet most stated mask-wearing continued to be crucial for now, as a result of the quantity of vaccinated Americans had not but reached a stage that scientists contemplate essential to considerably sluggish the unfold of the virus. Until then, there are too many possibilities for vaccines, which aren’t one hundred pc efficient, to fail, they stated.
“Crowded circumstances, indoors or outdoors, necessitate a mask until community levels of Covid are much lower,” stated Luther-King Fasehun, a physician and an epidemiology Ph.D. pupil at Temple University.
Sally Picciotto, an epidemiologist at the University of California, Berkeley, stated the choice to cease carrying masks indoors “depends on more people rolling up their sleeves to get the shot.”
Respondents additionally stated that so long as the virus was nonetheless spreading, masks had been essential to guard high-risk folks and those that can’t be vaccinated, like youngsters or individuals who have underlying well being situations.
“Until community transmission is lower, it protects the whole community and the other people in the room to wear masks,” together with youngsters, immunosuppressed folks and Black and Latino communities who’ve been hit tougher by Covid-19, stated Julia Raifman, an assistant professor of public well being at Boston University.
One-quarter of the epidemiologists in the survey stated they thought folks would want to proceed carrying masks in sure settings indefinitely, and a few stated they deliberate to proceed to put on them in locations like airplanes or live performance halls, or in the course of the winter virus season.
“Heck, I may wear a mask for every flu season now,” stated Allison Stewart, the lead epidemiologist at the Williamson County and Cities Health District in Texas. “Sure has been nice not to be sick for over a year.”
Alana Cilwick, an epidemiologist at the Colorado Department of Public Health, stated, “I plan to wear a mask indoors for the foreseeable future given the amount of vaccine hesitancy we are seeing, especially in higher-risk settings like the gym or on an airplane.”
Just one-fifth of epidemiologists stated it was secure for totally vaccinated folks to socialize indoors with out masks in a group of limitless dimension. A majority stated indoor gatherings must be restricted to 5 or fewer households.
Even exterior, the place the coronavirus is way much less prone to unfold, almost all of the epidemiologists stated it was essential to maintain carrying masks in crowds, when individuals are close to others whose vaccination standing they don’t know.
“Masks are the second-most helpful prevention strategy we have to vaccines,” Professor Raifman stated.
