🧵Today marks 1 year since the WHO designated #Omicron a Variant of Concern. This most infectious and immune-resistant variant was seized upon to scrap all remaining mitigation measures and normalize the pandemic globally. #CovidIsntOver #BringBackMasks 1/ wsws.org/en/articles/20…
Over the past year, billions of people have been infected globally. Officially, 1.4 million people have been killed by #Omicron, but excess death estimates place the real global death toll over the past year at 5.2 million, or 1/4 of all #COVID deaths. 2/ economist.com/graphic-detail…
Excess deaths are now elevated everywhere, a reflection of the horrific toll of #LongCovid and the reverberations of the mass infection policies implemented by nearly every capitalist government in response to Omicron. 3/

Spannende Daten zur Immunität nach #Omikron Infektion in Geimpften! Außerdem Tests des BA.4/5-angepassten #Booster in 2x „Wildtyp“ geimpften Mäusen. Vor allem bzgl. der Frage der „Immunprägung“ erhellende Studie mit vielversprechenden Ergebnissen!

doi.org/10.1101/2022.0…

🧵1/7
In aller Kürze die für mich wichtigsten Erkenntnisse:

1) Durchbruchsinfektion mit #BA4/#BA5 führt zu hohen Antikörpern-Titern gegen #Omikron (auch BA.1 und 2)! Das heisst die Befürchtung, eine Omikroninfektion würde keinen Immunschutz auslösen trifft nicht zu!

2/
Die Befürchtung der „Immunprägung“: durch die 3x-Impfung mit Wildtyp würden bei Omikron-Infekt ausschließlich Gedächtniszellen gegen WT reaktiviert. Die Studie schaut aber erst 1-2 Monate nach Infektion und siehe da: das Immunsystem entwickelte Omikron-spezifische B-Zellen!

💡2x BOOSTER SAVES LIVES—New CDC data shown today shows that 2 booster shots ⬇️lowered #COVID19 death rates by 📌14x (purple line) vs unvaccinated—plus amazingly, 2 boosters ⬇️deaths 📌3x vs 1 booster alone (blue). CDC soon to approve #BA5/4 booster software update—get it please!
2) What shocks me is how people just hand wave “oh I don’t need 3x lower risk of dying with another shot” as if it’s nothing. Jeez people. Also vaccines lower risk of seeing #LongCovid too. Don’t be so stubborn.
3) New #BA5 and #BA4-targeting coronavirus booster shots has now gotten EUA from the FDA for all age 12+… thus second boosters now eligible for those 12-49 finally! CDC advisors voting soon. Rollout imminent within days. Please get boosted. Hope it’ll get EUA for kids <12 soon.

@DrEricDing
Incoming—CDC vaccine advisers expected to vote Thursday on updated #BA5 variant boosters. New shots likely available within days. This is the booster I’m waiting for.
P.s. This updated booster is basically the same as the original just slightly modified spike configuration for BA5. I don’t need to see a new Phase 3 trial of 30,000 people for small software updates. Hence lab studies showing superiority over the old 1.0 version is okay. Get it.
3) to be clear— this variant update lab method is what we do with influenza vaccines yearly (instead of launching major new flu trials yearly). And I’m confident it will be similar with this BA5 mRNA vaccine update from the Wuhan 1.0.

Now it's been a while since I've talked abt #COVID19 in #Malaysia (except a month back abt cases among school kids in Penang).. but if ever anyone wants to hv an academic understanding of why there is a resurgence of cases.. here it is.. Point mutation !!
This is the start of @RolandBakerIII 's thread on the mechanism of how the BA.4 & BA.5 subvariants of the #Omicron evade action of antibodies..
A look at recent cases in the USA, showing in no uncertain terms about the dominance of #COVID19 cases from the #BA4 & #BA5 ..

1/4 - “On peut raisonnablement penser que le pic de la vague de contaminations est passé en France et passe actuellement sur une grande partie de l’Europe. L’expérience portugaise nous permet d’appuyer cette analyse.” leparisien.fr/societe/sante/…
2/4 - Si la France suit la dynamique portugaise de sa récente vague #BA5, alors le pic de mortalité pourrait être quinze jours après celui des contaminations, soit en France début juillet, avec un pic d’hospitalisations le précédant de quelques jours.
3/4 - Au Portugal, la mortalité #COVID19 enregistrée sur quatre mois, début avril - fin juillet, devrait être de 3000 décès. Si l’on poursuit l’analogie, en France, entre mi-mai et mi-septembre, on pourrait enregistrer 20’000 décès #COVID19.

1/9 - “Hospital admissions are rising across Europe and the US as highly transmissible #COVID19 variants drive infections, but the resulting illness is less likely to be severe or cause death than in previous waves, according to the FT and health experts.”
ft.com/content/f4794a…
2/9 - “The number of new #COVID19 admissions has grown by 40 per cent in the last week in France, 34 per cent in England and more than 20 per cent in several other European countries. The wave has been fuelled by the #BA5 #Omicron sub-variant.”
3/9 - “The rate of increased hospital admissions in the US is currently slower than in Europe at 6%. This reflects the decline of the #BA2 variant in the US. But as the #BA5 variant becomes dominant, the overall rate of growth is likely to accelerate.”

Reality check👇

#COVID19 deaths globally are at a similar level to March 2020. While deaths are now much lower than they have been at their peaks over the last 2.5 yrs, we must remember that in 3/20, we knew very little about this virus & we had no treatments & no vaccines
1/🧵
Now in July 2022, we have several life saving interventions that we are not utilising effectively nor consistently globally & deaths should be far lower at this point in the pandemic

It’s not over & are playing with fire by letting this virus circulate at such intense levels
2/
Among #Omicron lineages, #BA5 & #BA4 continue to rise globally.

BA.5 has been detected in 83 countries, with prevalence ⬆️ from 37% to 52% from 19 to 25 June. The rate of BA4 ⬆️ is not as high as BA5.

1/9 - “A surge in #COVID19 hospital admissions driven by the #BA5 of #Omicron, accompanied by the inability of vaccines to prevent reinfection, has prompted health policymakers to rethink their approach to boosters.”
ft.com/content/4f71ac…
2/9 - “Research into immune imprinting, whereby exposure to the virus via either infection or vaccination determines an individual’s level of protection, is now driving the debate over the make-up of #COVID19 vaccines.”
3/9 - “Immunologists say that, >2y into the pandemic, people have acquired very different types of immunity to the #SARSCoV2, depending on which strain or combination of strains they have been exposed to — leading to big diff in #COVID19 outcomes between indiv and countries.”

1/ Dangerous spread of misinformation by @BBC.

Do not be vaxed relaxed. Triple vaccination and prior infection with omicron #BA1 does not offer protection omicron variants #BA4 and #BA5 - which are currently driving the new wave of infection in the UK. 🧵
2/ #BA5 resists and escapes neutralising antibodies induced by triple-dose vaccination & antibodies induced by prior omicron (#BA1) infection.
3/ Please do all you can to prevent (re)infection. #COVIDisAirborne which means infectious particles are carried in the air we breathe. To protect yourself wear a good-fitting #FFP2 or #FFP3 mask 😷 especially when in indoor public spaces.

1/ Bad advice. Do not be vaxed relaxed. Omicron variants #BA4 and #BA5 - which are currently driving the new wave of infection, - resist & escape neutralizing antibodies induced by triple-dose vaccination & antibodies induced by prior omicron (#BA1) infection. 🧵
2/ Triple vaccination & prior omicron infection with #BA1 confer no protection against the new variant.
3/ Please ignore notorious Covid-minimiser, Prasad.

‘93-98%’ of people will not get #COVID19 if they wear a good-fitting #FFP2 or #FFP3 mask.

(Re)infection is not ‘inevitable’ and should be avoided. Continue to protect yourself.

Globally, #COVID19 cases has increased for the 3rd consecutive week with >4.1million cases reported to @WHO (18%⬆️ compared to previous week). During the same week, 8,552 fatalities were reported.

We @WHO know both are underestimates and both cases & deaths are too high.

📍NEW DOMINANCE of “ESCAPE ARTIST” Variants #BA5 & #BA4–together topping 52% of all strains in the US, all while #BA2 family going extinct. ➡️BA5&4 are highly evasive against past immunity—matches rise in #COVID19 hospitalization in US & many countries.🧵 covid.cdc.gov/covid-data-tra…
2) this is why FDA has recommended for updates booster shots— The panel’s vote paves the way for F.D.A. to push manufacturers to make reformulated boosters in time for Biden WH to offer them later this year, before an expected winter surge of the virus.
nytimes.com/2022/06/28/us/…
3) #BA5 has begun causing havoc in hospitalizations worldwide in many countries. Especially recently in Portugal that had a wave of hospitalization that neared it’s winter peak. UK is now being squeezed by BA5/4 too. 👇

🧵1/A new cohort study using de-identified data from South Africa to measure the severity of Omicron BA1 VS new #BA4 & #BA5 subvariants, found that of ~190K BA1 and ~4K BA4+BA5 patients, severe hospitalization & death from all variants was identical (aHR 1.01, 95% CI: 0.92;1.12) Image
2/Moreover, those with previous infection were conferred nearly 2X less risk of severe disease and death from Omicron BA1, BA4 & BA5 (aHR 0.19,95% CI: 0.16;0.22) VS those double vaccinated (aHR 0.58, 95% CI: 0.54;0.63) implying that vaccination was less effective than infection Image
3/ Finally, prior #Covid infection provided nearly equal protection against severe disease and death from all Omicron subvariants (aHR 0.19, 95% CI: 0.16;0.22) VS being triple vaccinated (aHR 0.24, 95% CI: 0.15;0.39)

The #COVID19 pandemic is once again spiraling out of control, driven by the highly contagious and immune-evading Omicron #BA4 & #BA5 subvariants. North America, Europe, Brazil & Australia are at the epicenter of the latest global surge. #CovidIsNotOver 1/ wsws.org/en/articles/20…
The global 7-day average of daily new cases now stands at 661,420, a 42% increase since the trough in late May! Official new infections are rising despite the dismantling of surveillance and reporting, with test positivity rates rising in each of these countries and regions. 2/ Image
Wastewater in Spain is at record levels! This key metric is rising rapidly in many countries. The sudden rise in test positivity rates means that unreported infections are occurring faster than those being documented by public health departments. 3/

⚠️Very worried about #BA5 causing #COVID19 hospitalization surges everywhere it goes—bad it’s very past-immunity-evasive. Portugal hit 80-90% of its old hospitalization peak recently. UK hospitals strained to the brink now too. Bad trends many in places.🧵

HT @jburnmurdoch Image
2) based on models, #BA5 and it’s close cousin #BA4, also past-immunity evasive, is surging so fast, it will likely be 50% of all #SARSCoV2 strains in the Us this week—and soon displacing all other past strains.

HT @JPWeiland Image
3) Why do we need to look at Portugal? It’s a highly vaccinated country, yet #BA5 has completely overwhelmed it. Vaccines work overall, but if a virus spreads unchecked without OTHER MITIGATIONS, vaccines not enough alone. We need vaccines+ PLUS other mitigations.
