"We should not undersell the vaccines. They offer excellent protection" said @linseymarr "I think we can really start thinking about ending mask mandates once everyone who wants to be vaccinated has had a chance to be fully vaccinated. And that should be in another month or two."
"The timeline on just how soon the CDC could loosen guidelines is unclear, since experts say masks indoors should stick around until every adult who wants the vaccine has had a chance to reach full vaccination. At the same time, over 116M Americans have already hit that mark."
"Once everyone has had the chance to get it, then we start to move into this personal risk decision making," @j_g_allen said. "And my feeling is that it's reasonable by July 4 or so that we'll be in a place to pull back on some of these mandates, assuming cases keep dropping ..."
"Marr, who is fully vaccinated, said she'd now be comfortable indoor dining, going to a grocery store without a mask on, or attending an outdoor barbeque mask-less, with people who are both vaccinated and unvaccinated -- though she would follow the rules in her community."
"Marr said she would be comfortable with her children, who aren't vaccinated, doing the same because she's generally been more concerned about them spreading it to someone who's vulnerable to COVID than she is about their risks of severe illness."
"The place she would still consider wearing a mask, Marr said, would be in a really crowded indoor environment, like a standing-room only indoor concert or a packed worship service with lots of singing. ... also consider if case numbers are high or vaccination rates are low..."
"Allen said he looks forward to traveling with his family this summer, mostly without masks. Like Marr, he said he would pay attention to how much virus is circulating in the community, as well as the social norms of the area he's in."
"I'm worried that if we don't relax restrictions, then people say, 'What's the point of getting the vaccine?'" said @j_g_allen.
"If we then don't pull back controls when it's time to pull back, we lose credibility"

This story about air cleaners by @LaurenWeberHP & @By_CJewett is important b/c:
- COVID risk in schools is still real & kids <12 yrs won't be vaccinated even by fall
- many well-meaning schools are buying worthless, even harmful products
- millions of tax-payer $$ being wasted
“It’s a high cost for nothing” @marwa_zaatari said" The company has sued her & another air-quality consultant for criticizing their devices. Of the pending case, Zaatari said it is a David-versus-Goliath situation, but she will not be deterred from speaking on behalf of children.
Many products offer promises only supported by the manufacturer.
The investment in proper air-cleaning (ventilation, HEPA filtration, upper-room gUV) will provide health benefits against respiratory aerosol infection AND many other issues for a generation.
An important piece on the dubious "air cleaning" products being sold to school districts & businesses. Via investigations by @LaurenWeberHP@By_CJewett.
It's important to stick to well-proven strategies like improved ventilation & HEPA filtration. (1/x) khn.org/news/article/a…
3/ An Op-Ed that @ChemDelphine, @marinavance, & I wrote to add awareness on imp. issues of cleaning air in schools & businesses.
All district constituents should work together to educate & advocate strongly for proven strategies.
2/ Summarized interventions for airborne infectious disease prevention:
1⃣ Commission buildings and examine existing systems
2⃣ Ventilate with clean outdoor air
3⃣ Improve the building’s air cleaning efficiency through evidence-based air cleaning treatment such as filtration
3/ Interventions, cont'd:
4⃣ If the ability to upgrade ventilation and air cleaning is limited, use portable air cleaners with high efficiency particulate air (HEPA) filtration
5⃣ Consider other evidence-based air cleaning approaches in the context of existing strategies
2/ "We encourage school districts to use stimulus funds to improve the indoor air quality of their schools. Use evidence-based strategies. Avoid technologies that have not been proven by peer-reviewed scientific research."
3/ "We encourage students, teachers, and the community to engage with district administrators and encourage them to leverage funds to support both the immediate and long-term health of students and staff." coloradosun.com/2021/04/23/saf…
I respectfully disagree that the recent (& important) editorial/review in @TheLancet "omits or dismisses crucial observations." A statement that "close contact" spread cannot be driven largely via aerosol inhalation is a mischaracterization of the inhalation route. (1/x)
(1) touching something/someone infected & transferring to yourself (2) receiving a direct spray of large droplets that hit e.g. mucous membranes (3) inhaling virus in aerosols at either close or long range onlinelibrary.wiley.com/doi/10.1111/in…
3/ All three pathways can happen at close-range. Direct observational evidence for any one of the three is nearly impossible for individual cases.
Article outlines clear reasoning why aerosol inhalation should be treated as an important (not only) driver. thelancet.com/journals/lance…
This dude is just wild. If he weren't so influential, best just to ignore his theories about the mysterious, undiscovered properties of air to kill viruses.
2/ What gets me is that by invoking the idea of an undiscovered force in outdoor air that is killing airborne viruses, he is somehow trying to change the narrative & ignore his constant opposition to airborne transmission and that EVERYONE agrees that outdoor air is safer.
3/ Enclosed indoor spaces trap exhaled aerosols from diluting into bigger outdoor spaces. Bringing magical anti-virus outdoor air inside is NOT the point. Pushing viral aerosol out IS the point.
