When South Korea, a model country for the pandemic, has >400,000 new cases in a day, leading the world per capita, you take notice. Tests 4X the US with <1/6th the population. BA.2 is 26% as of this week's report.
Very high 2-shot vaxx 87%, 3-shot 63%. The pandemic isn't over.
Relative to Hong Kong, it's death rate is very low. Boosters more than double. Great coverage of age 60+ No Sinovac vaccines.
BTW Hong Kong's booster 30% rate now exceeds the US (29%)
Relative to European countries with a BA.2-related hospitalization increase, South Korea's (BA.1) is more pronounced
Adding Vietnam as a comparator, 3 places (+ Hong Kong) w/ minimal Prior Covid and pronounced Omicron case surges
Hong Kong w/ extreme fatality rate, first signs of slowing
Vietnam's level of protection is impressive despite less vaccine coverage than South Korea @OurWorldInData

Reduction of grey matter, brain size, cognitive decline
Demographics of Covid cases and controls. Only 15 of cases were hospitalized and results did not change when they were deleted from analysis
One of the most important studies of the pandemic; further work to determine reversibility needed. Credit @OxfordWIN@uk_biobank Gwenaelle Douaud and colleagues for this contribution
My new essay @guardian
"Why one-shot after a Covid-19 infection should suffice to be considered fully-vaxxed" theguardian.com/commentisfree/…
Summarizes extensive new evidence that confirmed Prior Covid ("Natural Immunity" or NI) + 1-shot is as protective as 3-shots /1
These 6 new reports (5 in the last week) all demonstrate that NI + 1-shot provides a consistent high level of added protection from reinfection, across multiple variants, which is not ameliorated by additional shots /2
I've reviewed considerable other new data here, such as the J&J vaccine randomized, placebo-controlled trial report last wk @NEJM which showed NI had superior protection vs moderate-to-severe Covid than 1-shot of the vaccine (90% vs 56%, respectively) erictopol.substack.com/p/ground-truth… /3
