⚠️Don’t ignore—

"Ignoring variants today, suggesting they aren't important, leads us to ignore variants tomorrow.

Ignoring the variants of tomorrow is potentially a f***ing big mistake!"

…says Dr. @michaelmina_lab,
Harvard immunologist & epidemiologist
#COVID19 #vaccinate #P1 ImageImage
2) “variants are extremely concerning. Most data at this point shows anywhere from a 10-fold to a 30-fold reduction in nAb against the variants”
3) “When we mix these variants with elderly immune systems that will wane - we will see new cases emerge amongst fully vaccinated vulnerable in our communities this year. it will be bad in this fall and it will lead to outbreaks and deaths again.” 🔥
4) That’s why it’s critical than ever to vaccinate fast—and get **both shots** for fuller protection against variants. 1 dose strategy just not enough for variants anymore. See thread 🧵
5) Another evolutionary epidemiologist also worried about variants, especially the rise of the Brazil-origin #P1 variant

⚠️AIRBORNE >6 FEET / 2 METERS! The CDC finally acknowledged #SARSCoV2 has major transmission via airborne aerosols beyond 6 feet / 2 meters, not just close contact. The CDC/WHO & airborne deniers are a year late—and negligently endangered many. #COVID19 🧵
nytimes.com/2021/05/07/hea… ImageImage
2) The Centers for Disease Control and Prevention now states explicitly — in large, bold lettering — that airborne virus can be inhaled even when one is more than six feet away from an infected individual. cdc.gov/coronavirus/20…
3) The new language, posted online, is a change from the agency’s previous position that most infections were acquired through “close contact, not airborne transmission.”

Ummmm, a Hollywood movie right here—

15,000 minks were all infected with #COVID19 (100% antibody positive)

…then silence…

But 2 months later… ➡️ 75% of the minks were suddenly all #SARSCoV2 reinfected again.

(Study brought to you by: Denmark’s CDC).
biorxiv.org/content/10.110… Image
2) “genome sequencing showed that the virus circulating during this re-infection was most closely related to virus identified in the first outbreak on this farm but additional sequence changes had occurred.”

➡️ it was related to original (not some foreign variant), but mutated.
3) “Animals had much higher levels of anti-SARS-CoV-2 antibodies after re-infection than at free-testing.”

➡️ second infection boosted antibody levels.

American (unhealthy) privilege.

#vaccinate #COVID19 Image
2) Meanwhile in India … exactly as the cartoon ^ depicts.

“Whoever has to die will die” 😢
3) American exceptionalism… only the US had a group of misinformed red-hat wearing people so large that it resists vaccinations by the millions.

A WHO panel announced Friday that it would authorize emergency use of a coronavirus vaccine made by Chinese firm Sinopharm—allowing for entry into COVAX. It’s also first time that any Chinese-made vaccine received emergency authorization from WHO. #COVID19 washingtonpost.com/world/2021/05/…
2) it is the 6th vaccine that WHO has validated. Moderna still awaiting entry too apparently.
3) “This expands the list of Covid-19 vaccines that Covax can buy, and gives countries confidence to expedite their own regulatory approval, and to import and administer a vaccine,” WHO director Tedros Adhanom Ghebreyesus said at a news briefing on Friday.

SCHOOL #COVID FACTORS—

Pandemic theatre: Desk plexiglass shields (even increases risk—possibly disrupting ventilation).

No effect: Same teacher, reduced class size.

Good: Masking (teachers & kids), daily symptom screening, no extracurriculars, cohort.🧵
science.sciencemag.org/content/early/… Image
2) “School-based mitigation measures are associated with significant reductions in risk, particularly daily symptoms screens, teacher masking, and closure of extra-curricular activities.”
3) “A positive association between in-person schooling and COVID-19 outcomes persists at low levels of mitigation, but when seven or more mitigation measures are reported, a significant relationship is no longer observed.”

⚠️HUGE EXCESS DEATHS—global #COVID19 death toll is 2x higher than official data—6.9 mil worldwide. Deaths:

US 🇺🇸—905k
India 🇮🇳—654k
Mexico 🇲🇽—617k
Brazil 🇧🇷—595k
Russia 🇷🇺—593k

Likely hit 1918 Spanish flu death count by end of pandemic, says @IHME_UW. 🧵
statnews.com/2021/05/06/new… Image
2) That is about 38% higher than the current death estimate from the Centers for Disease Control and Prevention, 561,594.

➡️The new figure also surpasses the estimated number of U.S. deaths in 1918 flu pandemic, which was estimated to have killed approximately 675,000 Americans.
3) “We’re probably not yet at the global toll of Spanish flu and certainly not at the death rate from Spanish flu. But given what’s unfolding in India right now, Covid is going to rival Spanish flu at global level in terms of the count before we see the end of this epidemic”
