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 🧵 ⬇️

📌Florida is #1 in nursing home resident & staff #COVID19 deaths in August.

📌Florida is 2nd worst for nursing home staff vaccinations—only 48%.

📌Florida is #1 in new staff cases—94% of nursing homes had staff infected in August.

So @GovRonDeSantis?

2) BUT—“It’s hard to assess the current toll of the virus on people living and working inside long-term care facilities, as Florida stopped sharing this data with the public in May.” ⚠️
3) “Federal data used in the AARP report lags by about two weeks, and does not include information about the situation inside Florida’s assisted living facilities, which are not required to report to the national government.”

💡AMAZING BOOSTER DATA—New study shows 3rd shot has 91% efficacy (11x ⬇️lower risk) against #DeltaVariant infection versus 2 shots (>=5 months earlier) among age 60+. Plus, 3rd shot has ~95% efficacy (19.5x ⬇️lower risk) against severe disease!🧵 #COVID19 nejm.org/doi/full/10.10… Image
2) moreover. The enhanced booster effects begin being apparent after day 12, increasing higher effects starting even day 10 after the shot perhaps.
3) most were not that elderly either 60-69. I’m also glad to see they enrolled 14% Arab population. The bulk were vaccinated in early February. Thinking of all the people who got vaccines before March that could benefit from this. Image

📍NOT ENOUGH TO STOP VARIANTS—U.S. population immunity against #COVID19 still insufficient to resume pre-pandemic social behavior—still not enough #vaccination / natural immunity—need more masks & ventilation on top to prevent additional waves of variants. acpjournals.org/doi/10.7326/M2…
2) “The mean overall population immunity was 62.0% (CrI, 58.4% to 66.4%). Adults aged 65 years or older were estimated to have the highest immunity level (77.2% [CrI, 76.2% to 78.6%])…”
3) HOWEVER- “children younger than 12 years had the lowest immunity level (17.9% [CrI, 14.4% to 21.9%])” acpjournals.org/doi/10.7326/M2…

⚠️HOLY CRAP—11% of Israeli kids who got #SARSCoV2 now suffer from #LongCovid, says study of parents of 13,864 #COVID19-infected kids ages 3-18. ➡️Worse, they also found #LongCovidKids even among 3.5% of the kids who were **asymptomatic**👀—that’s serious!
timesofisrael.com/more-than-10-o…
2) More than 200,000 children under 18 have tested positive in Israel, with about half of them asymptomatic, the survey said.
“The meaning of this is that there are currently thousands of children in Israel suffering from long-term effects,” the statement said.
3) “these findings are in themselves distressing and call for further investigations into the effects of the coronavirus period on the cognitive/mental health situation of children in Israel,” the study said.

📌Fake #COVID19 tests likely used by over 150 people to board flights home after a pilgrimage—Israeli police investigating.
Offenders could be charged with fraud, forgery and spreading disease—criminal offenses that can lead to 5 year prison sentences.🧵
nytimes.com/2021/09/12/wor…
2) About 25,000 to 30,000 Israelis, most of them male Hasidic Jews, traveled to celebrate the Jewish New Year. Israel’s Health Ministry found that dozens of them had arrived back in 🇮🇱 infected with the virus despite carrying documents indicating that they had tested negative.
3) Prime Minister Naftali Bennett’s office said in a statement that it “views with utmost gravity” the entry of people with forged documents, “willfully spreading a disease,” adding that severe action would be taken against offenders.

Heartbreaking—5 kids are now orphaned after both mom+dad (age 37/39) dies of #COVID19 weeks apart. The baby was born by C-section while mom was on a ventilator, doesn’t even have a name yet.😢 Grandparents haven’t told the kids parents died yet. #vaccinate latimes.com/california/sto…
2) this story truly truly broke me. “The couple and their four children all contracted the coronavirus after a trip to Big Sur in July, which included a stop on the way back at an indoor water park in Orange County, Serey said. Davy was seven months pregnant when she got sick.”
3) Ironically sad— “Davy was a labor and **delivery nurse** at Kaiser Permanente Fontana Medical Center. Daniel taught **math** at Jehue Middle School in the Rialto Unified School District.”
