The overwhelming evidence for 3rd shot boosters *before* Omicron, reinforced by new data for benefit vs Omicron 1. The randomized trial of 3 shots vs 2 shots + placebo, 95% efficacy for preventing symptomatic infections across all age 16+ groups (N=10,125) cdc.gov/vaccines/acip/…
3. Marked reduction of hospitalizations and deaths in over 728,321 people with 3 shots vs matched 728,321 people with 2 shots, across all age groups thelancet.com/action/showPdf…
4. Now vs Omicron, the variant with substantial immune escape, the 3rd shot induced a 25-fold increase in neutralizing antibody titer pfizer.com/news/press-rel…
Clinical correlation with effectiveness data and duration of impact pending
PS I am getting very tired of people ("experts," CDC, journalists) negating the incontrovertible evidence for 3rd shots that existed prior to Omicron, which is one of the reasons why less than 1 in 4 US adults have had boosters

Most people haven’t heard of this test, which is available in the US. It accurately predicts Alzheimer’s (not just if there’s a risk, but when). It is favorably affected by exercise and likely many other lifestyle factors.
Here’s (almost) everything we know about it. In Ground Truths (link in my profile d/t X-suppression)
A major @Nature paper this week found a significant decline in dementia after an outdated Shingles vaccine.
I've reviewed the study and many other relevant ones in a new Ground Truths (link in profile)
A Table from the post
The effect in the 2 natural experiments differed substantially by sex with the benefit predominant in women
The vaccine against Shingles helps protect against dementia, results of a natural experiment, adding to prior evidence
"implications are profound"
New @Nature nature.com/articles/s4158… nature.com/articles/d4158…
Of >105,000 participants with 30-year follow-up, only 9.3% achieved healthy aging (age 70, w/o any chronic diseases). Their diet was significantly associated with this outcome🧵 @NatureMedicine
These are the specific foods that were linked with healthy aging and other outcomes. Green-favorable; Red-unfavorable
Adherence to these diets (most to least in quintiles) linked to healthy aging
A paper on microplastics accumulating in the brain was just published @NatureMedicine, open-access
I review the background and major implications in a new Ground Truths edition (link in my profile)nature.com/articles/s4159…
The human brain:
—had 7-30 times more accumulation of microparticles (MPs) than the liver or kidney (organs with previously documented high propensity)
—from people with dementia had 5X accumulation of MPs compared with non-dementia
—there was a marked increase of accumulation over recent years
Three new @NEJM reports on #H5N1 today 1. An overview by @MichaelGIsonMD and @DrJeanneM
"urgent need for vigilant surveillance of emerging mutations and assessment of the threat of human-to-human transmission"
2. Report of the 13-year-old Canadian girl who developed acute respiratory failure. Sequence of her H5N1 revealed 3 mutations that may be linked to higher virulence and adaptation to human cell binding
3. Review of 46 cases of mild H5N1 illness by CDC in 2024
