NEW—“Omicron is producing hospitalizations & sadly at least 1 patient has now died with #Omicron. The idea that this is somehow a milder version of virus—we need to set [aside] & recognize the sheer pace at which it accelerates.” @BorisJohnson #COVID19
2) #Omicron is now 49% of all London cases. thedailybeast.com/britain-report…
3) U.K. Health Secretary Sajid Javid said the number of Omicron infections “is doubling every two to three days,” and warned, “we’re in a new race, whether we like it or not, between the virus and the vaccine.”
4) If you’ve been infected before or gotten 2 shots—you need a booster. 2 shots or a past infection is not enough to protect you. #GetBoosted
5) Especially with 2 shots of Oxford-AstraZeneca vaccines — it’s not enough against #Omicron. It’s too different from the original Wuhan spike protein that our 1.0
version vaccines upon which they currently are designed against. See thread 🧵
6) Hospitalizations in London are up ⬆️ 30% in one week. In England as a whole, it’s up 12%.
7) As hospitalisations and deaths lag behind infections by about two weeks, Mr Javid said we could "expect those numbers to dramatically increase in the days and weeks that lie ahead". bbc.com/news/uk-596390…
8) As well as the expansion of boosters, new Plan B measures have been introduced in England to slow the spread of Omicron:

•People are being advised to work from home if they can, bringing England into line with Scotland, Wales and Northern Ireland
9) •Rules on face masks have already been tightened and they are now mandatory in most indoor public places, including theatres and cinemas
•From Wednesday, subject to parliamentary approval, Covid passes will be required to get into nightclubs and other large venues
10) Good news is a 3rd shot (Pfizer booster) after 2 shots of AZ puts one back up to 71.4% VE against symptomatic #Omicron disease after 2 weeks after 3rd shot, or 75.5% with 3x Pfizer shots. This is good news at least. Still waiting for hospitalization VE - coming soon.
11) Omicron is doubling every 1.6 days in UK 🇬🇧 according to @DrWilliamKu’s figure. That’s way faster growth than in South Africa. I think it’s maybe due to 2x doses of AstraZeneca being the main vaccine in the UK while SA haven’t used any AZ for a long time. Boosters now!
12) KEEP IN MIND— a lower severity won’t prevent mass hospitalization deaths if the virus is more contagious / evasive against past immunity. Exponential math will catch up ultimately much faster in the end. See 🧵 below 👇
13) If some of you want to dismiss #Omicron or #COVID19 as no biggie— then will you complain when the hospital is full later when you or your family actually need medical care? This man’s wife has breast cancer. Let this man’s message sink in 👇

📍The coronavirus is airborne. Very airborne. Even if you don’t see anyone—doesn’t mean the aerosols aren’t in the air. WATCH📺

➡️ you need high quality N95 / KN95 / KF94 / FFP2/ FFP3 masks.

➡️ also please ventilate, get HEPA filters, get upper room UV.
2) VENTILATION is key. Both ventilation and masks needed to reduce risk indoors. But most buildings not ventilated well enough.

3) AEROSOLS ARE AIRBORNE.

“Until we recognise that #COVID19 is airborne we are setting ourselves up for repeated failure”

💡New VACCINE RANKING of ability to neutralize #Omicron—Moderna appears to be the strongest against Omicron in this study, but still big drop. Pfizer next best (but we know infection efficacy is 30-34%), AstraZeneca & Sinopharm poor. J&J & Sputnik = zero.🧵biorxiv.org/content/10.110… Image
2) Natural infection immunity is on the left … “convalescent” = practically no neutralization against #Omicron in this study by itself without vaccine. Image
3) Meanwhile for SinoVac —one of the world’s most widely used vaccines, doesn’t provide sufficient antibodies to neutralize the #omicron variant, said 🇭🇰 researchers. But a 3rd shot booster seemed up help. bloomberg.com/news/articles/…

Don’t count on monoclonal antibody drugs to save you—German researchers have found that #COVID19 synthetic antibody therapies developed by Eli Lilly and Regeneron lose most of their effectiveness when exposed in laboratory tests to the #Omicron variant.
reuters.com/business/healt…
2) While many drugs work, I don’t think they will end the pandemic. Stopping transmission and opportunities for mutation will be what saves us in the end. Not just milder cases with expensive pharma treatment.
3) Many monoclonal antibody drugs are now in trouble against #Omicron

HIGHEST kids COVID hospitalization ever in England 🏴󠁧󠁢󠁥󠁮󠁧󠁿 of the whole pandemic… ➡️ But but but… I thought some politicians & economist had once said “kids are practically immune” to #COVID19. 🤦🏻‍♂️
2) Kids are known transmitters. They are not just like vaccinated adults. Kids are kids. Every hospitalization is a tragedy.
3) a 3 million person Danish study shows more kids in a household, more transmission. This is why we need to vaccinate to both protect kids and protect others in the household.

BREAKING—Largest study of 2-shot Pfizer vaccine effectiveness against #Omicron from largest health insurer in 🇿🇦:

📌33% VE against #Omicron (symptomatic?) infection

📌70% VE against #Omicron hospitalization (93% against #DeltaVariant before in 🇿🇦)

➡️Urgently need boosters.🧵 Image
2) the new study also mentions 20% greater risk of hospitalization among kids with #Omicron compared to an older strain last year. Image
3) Also, the protective effects of prior infection has waned and further erode by #Omicron. ➡️ Bottomline: don’t rely on past infection immunity! Image

“You can’t chase an exponential virus” with a govt rollout of boosters alone. You need to do more IMMEDIATELY to stop the exponential growth. #Omicron doubling in 🇬🇧 every 1.7 days ➡️ BoJo’s booster-only plan cannot stop fast enough. The political willpower to save lives matters.
2) UK’s growth also isn’t even the fastest anymore. Denmark has now topped it at 1.6 days per doubling of #Omicron.
3) BoJo is right that we need to set aside whether it’s “mild” or not (it’s no proven, and many epidemiologists doubt it). The acceleration of #Omicron is what will kill more.
