Why should every adult get a 3rd shot (booster) when eligible (6 months after 1°💉)? 1. A randomized, placebo-controlled trial, the gold standard for assessing efficacy, showed restoration of efficacy to 95.6%, in >10,000 participants across all age groups
2. Prevention of hospitalizations and deaths in a study of >728,000 people w/ 3-shots vs >728,000 matched controls (2-shots) thelancet.com/journals/lance…@TheLancet
3. We have no US National data by vaxx status but hospitalizations are starting to increase again and several states are reporting an increasing proportion of breakthroughs accounting for them
4. The US is doing a poor job of rolling out boosters relative to many other countries.
Only 1 in 3 people of the highest risk group, age 65+, have received one. Only 1 in 7 overall who are eligible.
5. Despite the compelling data and the current predicament, there is unwarranted and serious division at the top @CDCgov and among some experts who have been in denial of the vaccine effectiveness waning issue for months, resulting in mixed messages to the public and confusion
6. Meanwhile, 2 states have taken the appropriate steps of opening up boosters for all over the age 18 (California and Colorado) which is unprecedented (overriding CDC and FDA). And many countries have made boosters eligible for all adults their policy, including Canada.
7. Getting a booster when there'a a surge in your state is not the best timing ;-)
Also highlights that the booster rate across the US is remarkably low.
8. New data today from the UK shows boosters restore vaccine effectiveness for protection vs symptomatic infection to over 90% (AZ 93%, Pfizer 94%) khub.net/documents/1359… gov.uk/government/new…

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A major @Nature paper this week found a significant decline in dementia after an outdated Shingles vaccine.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
