If You’ve Had Covid, Do You Need the Vaccine? ✍️: ⁦@apoorva_nyc

Spoiler: Yep nytimes.com/2021/10/12/hea…
“Some consistent patterns have emerged: Two doses of an mRNA vaccine produce more antibodies, and more reliably, than an infection with the coronavirus does.”

nytimes.com/2021/10/12/hea…
“Only 85 percent to 90 percent of people who test positive for the virus and recover have detectable antibodies to begin with. The strength and durability of the response is variable.”

Today @NYCMayor de Blasio told @BrianLehrer that @WNYC/@Gothamist's recent series on ventilation in @NYCSchools is inaccurate

He should read our latest:

NYC Officials Say School Windows Can Always Offer Solid Ventilation. Independent Scientists Disagree
gothamist.com/news/nyc-offic…
And as a fun exercise in science media literacy, let's break down the Mayor's response...
Two weeks ago, Brian Lehrer asked @NYCMayor/@BilldeBlasio whether he had heard that the air purifiers @NYCSchools had purchased for every classroom in the city lacked HEPA filters, an industry standard.

The mayor said he'd look into it.

NYC Approves 4,000 Classrooms For In-Person Schooling Despite Unreliable Ventilation

Part 2 of our look at the city's back-to-school COVID precautions...

Looking through building surveys conducted by NYC's Department of Education, @jeffwilen found thousands of classrooms have been cleared for occupancy despite relying exclusively on functioning windows for ventilation.

She even made an interactive map.🙏🙌

@jeffwilen Got interrupted mid-thread. Dang work. Let's continue.

Aerosol scientists would probably raise their eyebrows at this part about the classrooms "relying exclusively on functioning windows for ventilation"...

“In addition, the [Intelligence Committee] was able to reach broad agreement on several other key issues. We judge the virus was not developed as a biological weapon…” dni.gov/files/ODNI/doc…
“Most agencies also assess with low confidence that SARS-CoV-2 probably was not genetically engineered; however, two agencies believe there was not sufficient evidence to make an assessment either way.” dni.gov/files/ODNI/doc…
Remember when a major magazine entertained the ideas that SARS2 was a bioweapon or genetically engineered despite scientific evidence to the contrary? Good thing that didn’t happen because it would be pretty embarrassing right now…

Every now and again, @NYMag's @intelligencer decides to publish COVID misinformation.

The latest example comes courtesy of @davidzweig and centers around masking for kids.

It makes the same tired arguments that I've been hearing for months now. Let's take a look...
Zweig starts by misrepresenting a single study from Georgia that looked at 90K students/169 schools (cdc.gov/mmwr/volumes/7…).

He insinuates that the study found no protection with masking for students.

In truth, student masking reduced COVID incidence by 21%...
The trend did not reach statistical significance, and the authors give a logical reason why.

But the trend was still there.

Also, the lack of statistical significance could have been due to the small sample size (only ~80 schools in the groups with/without masking)

Here is the issue with Leonhardt’s takes on public health and COVID:

They often misconstrue data, don’t see the bigger picture and can mislead people… (a thread)
First, I’m surprised that anyone (without an agenda) can look at this national map and essentially say “You know what? Some parts of this country are going to be alright.”

I mean, it looks like a scene from the “Floor Is Lava” Image
Second, many counties in the states he mentioned ***DO*** fall in the danger zones or are moving in that direction.

The eastern half of New Jersey, Suffolk County, Mass (home to Boston) and Milwaukee County, Wisc. are either under substantial or high risk. ImageImageImage

News reports are suggesting that the J&J vaccine is less effective based off a new antibody study (preprint).

But the preprint’s results don’t match real-world findings.

And I would argue that these headlines don’t match the preprint’s results either...
I say that because:

1) The preprint didn't measure effectiveness but rather the antibodies’ abilities to neutralize variants

2) The preprint reported a reduction in J&J neutralization for all variants, not just delta and including the parental virus. 🧐 biorxiv.org/content/10.110…
Plus, there is real-world effectiveness data (aka measurements of protection against actual disease) showing that J&J ***IS***effective against the parental and alpha variants. medrxiv.org/content/10.110…

NYC Unions' Vote (Today) Could Force Government Retirees Onto Privatized Health Insurance

✍️: @clewisreports via @WNYC / @Gothamist

“The move will affect some 250,000 municipal retirees, hundreds of whom marched in protest against the changes in Manhattan last week in the midst of a heat wave.” gothamist.com/news/nyc-union…
Some critics are concerned that access to doctors will decrease and out-of-pocket costs will rise. Other city retirees lament that they haven’t been able to evaluate how the change will affect them because the deal has been made behind closed doors. gothamist.com/news/nyc-union…

To gauge what might happen going forward with the delta variant, @WNYC / @Gothamist asked virologists, immunologists and epidemiologists to break down how the delta variant could affect New Yorkers based on their vaccine status.

The answer seems pretty straightforward for the unvaccinated, courtesy of @theodora_nyc...
gothamist.com/news/why-the-d…
But just how bad could it be? I asked the folks @PHICORteam to sketch out an outbreak model

Imagine the Bronx had never experienced COVID. Ok, now what happens if you drop 10 people with alpha, delta or the original strain into that unacquainted community gothamist.com/news/why-the-d…

Unlike the conversations about masks and variants, this time, the evidence for a lab leak hasn’t changed. Which is to say: there isn’t any yet.

“I think almost everybody agrees that the facts are very thin.” -@mlipsitch

🎯: @MaddieOBender v @motherboard
vice.com/en/article/n7b…
"This is about the bounds of what's worth following up as a possibility, which is different from a standard scientific debate. It's how to interpret the scantiness of the evidence, rather than how to interpret the evidence.” - @mlipsitch vice.com/en/article/n7b…
"The scientists interviewed for this story advocated for further research and investigation into the origins of the coronavirus, including the possibility of a lab leak, but all agreed that there is currently no solid evidence suggesting anything other than a natural spillover.."

@justinulysses @BeeBrookshire @Anna_Rothschild @amymaxmen The most vocal proponents of lab leak consistently posit lab manipulation of some variety.

Why?

Because as far as we know Shi Zheng-Li’s lab at the Wuhan Institute of Virology collected bat samples from 2010-2015...
@justinulysses @BeeBrookshire @Anna_Rothschild @amymaxmen If those field teams had caught SARS-CoV-2 back then, it should have sparked outbreaks years ago.

Ok, so what’s left?

The WIV team safely brought SARS2 (or a close relative) back to their lab between 2010-2015 but then was experimenting with it in 2019. This is a long shot...
@justinulysses @BeeBrookshire @Anna_Rothschild @amymaxmen ...and it’s speculation.

Alternatively, the lab had continued field surveys into 2019 without telling anyone (speculation bordering on conspiracy theory)...

@MMKavanagh That’s why that paragraph in @KatherineEban’s VF story is so misleading:

BSL-3 labs are specifically designed to study respiratory pathogens like SARS-CoV-2. cdc.gov/training/quick… Image
@MMKavanagh @KatherineEban People study anthrax in BSL-3 labs. Anthrax! ncbi.nlm.nih.gov/books/NBK53535…

Plus BSL-4 labs are built upon the principles of BSL-3. Image
@MMKavanagh @KatherineEban While BSL-4 labs are recognized for their pressurized suits and vacuumed-sealed double doors, BSL-3 labs also take extra precautions with ventilation...because again, BSL-3 labs are meant for respiratory pathogens. cdc.gov/labs/pdf/SF__1… ImageImageImageImage

"To explain where SARS-CoV-2 came from, look at processes with scientific explanations and precedents."

@d_samorodnitsky gets it.

If the question “are they equally likely?” the answer is absolutely not." massivesci.com/articles/sars-…
"It’s scientific malpractice to pretend that one idea is equally as meritorious as the other. The lab-leak hypothesis is a scientific deus ex machina, a narrative shortcut that points a finger at a specific set of bad actors." massivesci.com/articles/sars-…

The Intergovernmental Panel on Climate Change first met in 1990, where it predicted that GHGs could fuel global warming.

Even as more evidence accumulated, efforts to sow doubt delayed action.

The “natural origins” vs “lab leak” debate around COVID-19 has entered this realm... Image
Doubters of climate change often called for “direct evidence” -- or irrefutable proof that carbon begets warming begets catastrophic climate/weather.

Ex. The National Academy of Sciences report on June 7, 2001 was followed four days later by these comments by Pres. Bush. ImageImage
Despite years of research pointing toward anthropogenic disaster, the doubt led to a “both sides” conversation in news media.

To this day, deniers still yell “Ice Age!” as megafires and rain-packed hurricanes pummel us.
