10% of all #COVID19 hospitalizations last week were among fully vaccinated, despite >50% adults fully vaccinated in the UK— ➡️ this is the #DeltaVariant, which is 99% of all 🇬🇧 cases. I’m a big 2-dose vaccine advocate—but we still need strong precaution.🧵news.sky.com/story/covid-19… Image
2) Please take #DeltaVariant seriously — it’s the fastest transmission variant known to date. Much much faster. And it has somewhat vaccine evasion, especially 1 dose, and it is much more severe (higher risk of hospitalization)
3) Because #DeltaVariant is roughly 2x more contagious — ie 2x the R0 of the original virus, the R0 of Delta is likely 6-7. Let’s assume 6, and someday hit 70% *2-dose* with 90% efficacy (but AZ is ~60%), only then can we stop it… but no country is there yet.
HT @GosiaGasperoPhD Image
4) But efficacy of AZ against #DeltaVariant is not 90% (it’s 60%), Pfizer is 88% in one non-trial study. However, 1 dose of vaccine (both types averaged) is just 33%. And many countries are just 1 dose vaccinated.
5) Even @JoeBiden is warning everyone about #DeltaVariant and the urgency to get 2 dose vaccinated. And that it’s dangerous to young people. That’s quite a statement of a presidential warning.
6) Look at the trajectory of Delta versus the previous reigning #alphavariant - former most common variant worldwide. Delta is spreading much faster in the US (and in UK too - where it’s now 99%) Image
7) Aside from New England, most of the US is not higher in fully vaccinated than UK 🇬🇧. And the Deep South and certain Mountain zone states very low vaccination rate. This bodes poorly for when #DeltaVariant surges more. And it will. Image
8) last week, CDC finally upgraded #DeltaVariant warning to VOC. But the WHO warned and upgraded Delta being a VOC back in early Many. Over 4 weeks ago!
This is CDC’s biggest fumble of the year. Now #Delta is over 10% of all cases in US and surging.
9) This is the Delta variant causing double outbreaks in 2 schools in Israel 🇮🇱 this week alone.
10) if you watch one short video series today, let it be this one on the #DeltaVariant - this is why we need to be vigilant. Part 1 of 3. See thread 🧵for rest of the series… ⬇️
11) Not just hospitalizations, but a lot of breakthroughs leading to deaths with #DeltaVariant as well. This is from a PHE 🏴󠁧󠁢󠁥󠁮󠁧󠁿 report last week.
12) here is another way to look at the #DeltaVariant breakthroughs. This is the same PHE (England’s CDC) data as above but in figure form. Sobering.
13) Vaccine effectiveness against #DeltaVariant according to @PHE_uk — averaging AstraZeneca & Pfizer together (even if different), you can see a substantial drop for 1 dose. But even 2 doses has a ~8% drop as well. Also AZ’s 2 dose is actually 60%.
assets.publishing.service.gov.uk/government/upl… Image
14) Someone in every state and local govt needs to see the data and hear the warning that #DeltaVariant is coming. We all want the damn pandemic to be over, but we were just in an intermission. Act 2 is coming. India 🇮🇳 was the warning to the world what #B16172 Delta could do. ⬇️
15) The CDC needs to take urgent action now. endcoronavirus.org/blog/cdc-unive…
16) Siri, define “#DeltaVariant is fast spreading”….

➡️ Delta variant can infect people in mere seconds via fleeting contact.

Siri, does this fleeting exposure infection happened often?

➡️ it happened twice in one outbreak. Video camera evidence supported. See thread 🧵 ⬇️

📰BREAKING UPDATE—A close friend of @Boeing whistleblower John Barnett who was found dead in his hotel parking lot last week (while still testifying against Boeing) said he had told her just before his court deposition—➡️”If anything happens to me, it's not suicide." See 🧵👇
2) "I know that he did not commit suicide," said Jennifer, a friend of Barnett's. "There's no way." ➡️Jennifer said they talked about this exact scenario playing out.

However, now, his words seem like a premonition he told her directly not to believe.

3) "I know John because his mom and my mom are best friends," Jennifer said. "Over the years, get-togethers, birthdays, celebrations and whatnot. We've all got together and talked." When Jennifer needed help one day, Barnett came by to see her. They talked about his upcoming deposition in Charleston. Jennifer knew Barnett filed an extremely damaging complaint against Boeing. He said the aerospace giant retaliated against him when he blew the whistle on unsafe practices.

📍Hey folks—on #TikTok—as an American born in China—I have a few thoughts in this post. First of all, I would NOT ever recommend allowing TikTok to access your contact book 📔 of friends, or let TikTok connect to find your Facebook friends, or add your phone number. TikTok claims to be a “global private company” but it’s a wholly owned Chinese company—how big of a deal is it? Well, years ago, Google hit the nuclear eject button and forced itself to fully pulled out of mainland China—why? Because Google got into a fight with Chinese govt—because any media company operating in China must be subject to CCP control and grant communications access (read: for censors/monitoring/data tapping) to the CCP government. Google refused—and hence Google doesn’t operate anywhere in mainland China anymore. For same reason… TikTok being owned by Bytedance, a wholly owned China company—they are subject to same CCP control. TikTok just needs to divested from China and become US owned. Do yourself a favor meantime — disconnect your address contact book 📕 and your FB from TikTok if you must use it, and try not to use your📱number if possible (but still use a 2FA). I don’t want a ban of TikTok but I do support the TikTok divestment from China (so that it is fully US owned). I think TikTok is useful and powerful, but we need to secure it for us fellow Americans by supporting the ***divestment*** so that US controls it. I hope people see I’m not anti-TikTok—I just want us to make it better and more secure to protect our freedom of speech, privacy, and civil liberties. Thanks for listening. And may there be peace ☮️ in the Middle East.Image

2) I recommend you disconnect as many access points to your phone as possible from TikTok, if you must use it. Trust me on this. I use a ton of social media (I run other large social pages besides Twitter)—but TikTok I don’t touch beyond the most basic limits. Image
3) Congresswoman @RepSpanberger knows what’s she’s talking about — she was a former CIA officer. TikTok will always be subject to Chinese data control as long as it is Bytedance owned.

⚠️HOLY SMOKES—A famous whistleblower against @Boeing on safety issues, has just been suddenly found dead in his truck in his hotel parking lot—all while **testifying in the middle of his week of depositions** against Boeing. JFC. Many of John Barnett’s claims about dangerous Boeing practices have already been verified by the FAA. If we don’t hold accountability for his death, whistleblowers won’t come forward in the future—which would endanger publicly health & safety.

2) WTF — “It said the 62-year-old had died from a "self-inflicted" wound on 9 March and police were investigating.” ➡️ people don’t suddenly commit suicide in a parking lot while at a hotel to testify against @Boeing for days and days.
@Boeing 3) Everyone needs to watch John Oliver @LastWeekTonight episode on Boeing immediately… it’s fire 🔥

“We’ve known, there are lots of studies (that show) up to 50% of all cases are transmitted asymptomatically, which means fever is not the relevant thing here.” And many patients never develop a fever at all during a COVID-19 infection.

2) This means if they are feeling kind of sick but don’t have a fever, they may not isolate at all based and may spread the virus to others. The guidelines are “wishy washy” at best and require people to self-diagnose… if an illness is COVID-19, flu, RSV

miamiherald.com/news/coronavir…
3) “Feeling better is subjective, right? What is ‘feeling better’ to one? If you have symptoms that aren’t better explained by another cause, we don’t have the testing for other causes. And what is ‘better explained’? All these things are just so nebulous and undefinable,”

⚠️BEYOND ANGRY—Lots of confusion on CDC’s new isolation guidelines— why? Because The CDC MADE THEM CONFUSING & VAGUE ON PURPOSE. Proponents claim it still has “some isolation” & still “some precautions”. But if you read actual guidelines (which are clear as mud)—see if you think they are vague/confusing…

1) stay home if symptoms “not better explained by another cause” ➡️ummm WHAT THE HELL??? Do people need to both likely ask doctor to exclude all other causes, or SELF-DIAGNOSE and play SELF-EPIDEMIOLOGY to attribute symptom causation to be <50% other cause? How do people even do that? Give me a frigging break.

2) If no fever, “Symptoms getting better overall”—➡️how do you define BETTER and OVERALL? 💡What if sneezing less frequent but runny nose still bad? 💡What if coughing less, less headache, but sneezing more? HOW THE HELL DO PEOPLE WEIGHT THESE DIFFERENT SYMPTOMS?!?! (Also keep in mind 50% of all COVID transmission is asymptomatic…. So this one is disingenuous to begin with). What the heck @CDCgov — you know this is outright dereliction of duty to put out trash guidelines like this!

3) After you go back to school/work/social settings—➡️for next 5 days (which does NOT guarantee you’re not infectious anymore at all to begin with)… “take precautions such as …. [LIST]… and/***or*** [LIST]”… the 🔥key detail I want to highlight is the super vague “or” near the end of that sentence! Why? Well, the explicit meaning therefore is simple “CHOOSE ONE OF THE ABOVE [LIST] OF PRECAUTIONS”. Thus, the @CDCDirector is basically telling you that you can do almost nothing and casually do one like “Simply TEST” and you can be around others—the CDC doesn’t even say “Only if you test negative”—just simply “test”!

This is honestly one of the WORST guidelines the @CDCgov has ever written. It is purposefully vague and allows a myriad of loopholes and subjective interpretations— exactly the kind of stuff corporate executives and politicians love — they can say they are complying with the CDC while doing virtually nothing much at all to protect people and public health!

This on on too of the already horrible shoddy data/analysis that the guideline is supposedly based on (see earlier 🧵), and based on data from likely illegally enacted CA guidelines (see other legal complaint 🧵)…. ➡️This is honestly one of the worst despicable disingenuous corrupt guidelines that the @CDCgov @CDCFlu has ever done and @CDCDirector has ever rubber stamped. The CDC used to be a shining beacon on a hill—it is now inept and/or complicit and has betrayed its mission to disease *control and prevention* that is in its very name.

(Share if you agree. Or explain in comments if you disagree.)

P.s. to my friends inside the CDC network—know that I respect you very much for your tireless work and efforts.🙏 The arc of the moral universe is long—but it does bend to justice. Keep doing quality science, keep internally fighting the good fight for public health, and know that your efforts to voice your opposition to CDC leaders will not in vain. The inept political leaders do not represent for all of you, and do not take away from your best efforts to protect public health. Don’t be afraid to stand up for reason, stand for good unpolluted science, and stand on the right side of history. In a world of public health—Don’t be a Mandy Cohen, be a Rosa Parks. Stay strong.✊🏼

2) The reason I’m able to know about CDC internal discussions and thinking is that I had advanced notice and had insider insights into rationale & knowledge of the data analyses they ran. It’s sooooo bullshit…. Here is my longer thread 🧵 explaining the JUNK IN ==> JUNK OUT. 🗑️
3) this kind of trashy data analysis justification would get past any doctoral Epidemiology program. My former mentors once chastised me for running the very type of trash analysis that CDC used to justify. And they used CA policy data—which was dubious to begin with.

I am devastated—I saw with my eyes what’s coming from CDC tomorrow. My sources told me on what their rationale is based. And based on what I know (epidemiologist for 20 years)—it is complete bullshit crafted on thin flimsy data. I can’t believe CDC has such incompetent leaders.🧵 Image
2) what the CDC is doing is relaxing the guidelines of isolation to effectively ‘you can go out and have fun as long as you’re improving since yesterday’. Yes it’s ridiculous. Others have written on it. And it is totally public health abdication. newrepublic.com/article/179304…
3) but what are the hell are folks at the CDC thinking??? First of all, someone in CDC did a very basic short term state-level analysis of a certain unnamed states (you can guess which) that did the shitty policy early and look at the rough short term correlations. But covid had already peaked / peaking in the big state by the time the crap policy was enacted!!! Why is this junk? ….
