ICU admits may be the best proxy for lack of vaccinations. Israel and the US have low rates of vaccination (65, 63%) and have seen rising ICU rates in their Omicron waves (not seen in high vaxx % countries) @OurWorldInData
Clarification: Colors are swapped on the vaccine right-sided panels. Israel has slightly more 2-shot vaccination and >2X boosters
Important graph from @StavKislev that supports my point

2. The vaccine effectiveness (VE) vs Omicron symptomatic infection vs Omicron falls off 15+ weeks, as was seen with the Israeli data, here more so with Pfizer compared to Moderna
3. But protection (VE) vs Omicron hospitalization remains quite high (Moderna > 90% thru 9 weeks)
How to reduce your chance of dying from Covid by 99%?
Get vaccinated and a booster.
One of the most impressive graphs I've seen for the impact of vaccination in the US pandemic
(thanks @redouad@OurWorldinData for re-plotting my makeshift graph from earlier today)
Highlighting the data above are for all ages
Graphs for vaccination vs deaths by age groups (w/o booster partitioned):
Now deaths by age groups: 65+, 50-49, 18-49
For each group, death is reduced by 99% for vaccination plus booster compared with unvaccinated (down to zero for youngest age group) ourworldindata.org/grapher/united…
What to make of Omicron's BA.1 and (sister) BA.2 lineages?
Both are hyper-mutated with over 50 mutations but many are different, particularly in the spike and ORF1a regions outbreak.info /1
There's not any functional or epidemiological data to show any meaningful differences....yet. But BA.2 has become dominant in Denmark, out-competing BA.1, and its prevalence is rising in India, Singapore, Sweden, the UK and other countries /2 Graph via @Mike_Honey_
The spread of BA.2 supports increased transmissibility (hard to imagine beyond BA.1, O's sister). On Jan 21st, UK designated it as a variant under investigation ft.com/content/34fef1… More to learn, keep 👀, no reason for distress at this point (we already have enough of that)
Debunking the notion that boosters don't reduce Omicron symptomatic infections. Another new study from Qatar shows they are halved medrxiv.org/content/10.110… matched >400,000 people with mRNA vaccines 2 vs 3-dose
Booster vaccine effectiveness vs Omicron infections 62% (2 dose 32%) @UKHSA in people without Prior Covid assets.publishing.service.gov.uk/government/upl…
and higher with Prior Covid, hybrid immunity, as seen in all studies
Now there are 3 reports for vaccine effectiveness vs Omicron hospitalization, @UKHSA, @KPSCalResearch and today's @CDCMMWR. They are quite consistent for marked protection of the 3rd shot (booster). My summary table here
Here are the data from the new CDC report for vaccine effectiveness for both Delta and Omicron, 2-dose or 3-dose and vs Emergency Room visits or Hospitalizations
It seems the people who write the vaccines w/ a booster aren't working against Omicron are completely out of touch with the data
I'd consider ~90% effectiveness vs hospitalization pretty, pretty damn good assets.publishing.service.gov.uk/government/upl…
Especially compared with 44% without a booster
Then there's data for age 65+:
94% effectiveness, going to 89% after 10+ weeks khub.net/documents/1359…
Maybe people will realize that we're very fortunate, given Omicron's extensive immune escape, to have this level of protection from an extra dose of a vaccine directed against a virus from 2 years ago erictopol.substack.com/p/were-very-lu…
