Individuals who received at least one dose of mRNA vaccine had a 25% reduced risk of death from ANY cause compared to non-vaccinated people...Mortality from #COVID19 was reduced by 74% among vaccinated people, again confirming effectiveness of vaccination epi-phare.fr/actualites/comm…

The grifting is bad enough, but the grubby vulgarity of it all should embarrass every American.

One of the anti-vax movement’s favorite talking points is:
“Look at the Amish. They don’t vaccinate and they’re healthier.”
Well, measles keeps putting that claim to the test.
Pennsylvania now has 977 confirmed measles cases, 195 hospitalizations and 5 deaths.
Of those 977 cases, just FOUR were in vaccinated people.
And we’ve seen this experiment before.
During the massive 2014 Ohio measles outbreak, MMR coverage in the affected Amish households was estimated at only 14%.
99% of the measles cases were Amish.
More than 10,000 people were subsequently vaccinated as part of the effort that contained the outbreak.
The Amish religion does not prohibit vaccination. Some Amish communities simply have very low vaccination rates.
And when a highly contagious vaccine-preventable disease enters one of those communities, we get to see exactly what happens.
The virus doesn’t care about anecdotes, ideology or anti-vax memes.
Vaccination works.

Two new BMJ studies suggest that robotic assisted hip and knee replacements offer no clear benefit over conventional surgery for implant survival, revision risk, or surgical complications

Since yesterday I’ve been grilling my husband about the Flydubai incident. He’s a commercial pilot. I threw every conspiracy at him until he snapped.
His exact words: “People already calling this fake is insane.”
So here’s what he said about the three dumbest theories.
1- “How did anyone get into the cockpit? The door locks from the inside.”
There’s a door-release switch right next to the pilot. He can unlock it from the flight deck. Once it’s released, people on the other side can shove it open and get in. Locked does not mean sealed forever.
2- “Why didn’t the oxygen masks drop?”
This isn’t a movie. Masks don’t fall because something scary happened. They deploy only if cabin pressure drops. A steep descent, even a violent one, does not automatically dump cabin pressure. No pressure loss, no masks. Simple as that.
3-“How did people reach the cockpit if the plane was nose-diving?”
“Nose dive” does not mean the jet was vertical. It was pitched down, not at 90 degrees. That attitude doesn’t pin you in your seat. It throws you forward, toward the cockpit. If you get up, you’re not fighting the dive. You’re being shoved down the aisle faster.
That’s it. Not a film. Not a hoax script. Just how the airplane actually works.

There is no evidence vaccines cause autism.
There never was.
~650,000 children in a Danish study.
No link between vaccines and autism.
You've been deceived...

As a doctor, I've sat across from parents and told them the words no one should ever have to hear: a single pill laced with fentanyl took their son.
That's why I worked with Republicans at the state house to crack down on drug traffickers.
I'll never let politics get in the way of saving lives.

Interesting.
A national cohort study of 28 million individuals found:
No increased risk of 4-year all-cause mortality in individuals aged 18 to 59 years in persons vaccinated against COVID-19.
It's almost like antivaxers are liars and had no evidence...

As an emergency room doctor, I know public safety takes teamwork. I’m proud to have earned the support of three law enforcement organizations that put their trust in me to work alongside them, support those who protect our communities, and keep Arizona safe.

I’ve worked across party lines to stop insurers from denying life‑saving care — and I never took a cent of corporate PAC money. My opponent says he’s running for Congress to fight for Donald Trump. I’m running to fight for you.

Well the JAMA study of 28 million people in France found *reduced* all cause mortality among those who are vaccinated. If the vaccine was increasing cancer rates you’d see it there. We don’t. In fact every tumor type they looked at showed a statistically significant *reduction* in incidence among the vaccinated compared to unvaccinated.

This is strong evidence that your “hypothesis” is not only wrong but backwards. I’d love to see more large studies providing even more proof. Good science takes time though.
More importantly. Epidemiology isn’t about disproving every possible association some rando on the internet alleges. You’d do better to focus your efforts on explaining real trends (e.g. why has CRC been increasing for two decades before COVID) rather than imagining ones that aren’t present.

As an ER doctor I hate these e-bikes…
Please wear a helmet
Don’t drink alcohol and e-bike
Don’t carry a baby while riding an e-bike
Don’t e-bike after taking your blood thinners and reminiscing about your last hip fracture

The latest numbers from the CDC arrive as President Trump and RFK Jr. seek sweeping changes to the childhood immunization schedule.
Medical misinformation and fear are just as contagious and deadly as the preventable diseases they allow to spread.

I care less about @SecKennedy not having an MD or PhD and way more about him being a raving, rabid antivax conspiracy theorist hellbent on destroying US federal medical, public health, and biomedical research.
Let's be clear - none of the three HHS secretaries under Presidents Obama and Biden held an MD or PhD.
Kathleen Sebelius (Obama, 2009–2014): Held a Bachelor of Arts (Trinity Washington University) and a Master of Public Administration (University of Kansas). She did not have a doctorate or medical degree.
Sylvia Mathews Burwell (Obama, 2014–2017) did not possess a master's, PhD, or other advanced degree.
Xavier Becerra (Biden, 2021–2025): Held a Bachelor of Arts in Economics and a Juris Doctor (JD) from Stanford University. He is an attorney, not a medical doctor or PhD holder.
So - why has mainstream media made such a BFD about Kennedy not being a scientist or MD? Why do they continue to hammer at this?
We have lost our collective minds on this subject.
US child vaccination rates have plunged since before the pandemic, with kindergarten classrooms in more than 70% of counties now lacking herd immunity against measles.

Anti-vaxxers love warning you about “Big Pharma.”
The corporations are greedy. The scientists are bought. The regulators are corrupt. The doctors can’t be trusted.
Then, almost on cue, someone in a white coat appears online to tell you about the treatment the medical establishment supposedly doesn’t want you to know about.
Sometimes that person even has an MD after their name.
And sometimes, conveniently, there’s a supplement store, treatment program, paid newsletter, affiliate link, clinic, book, course, or product waiting nearby.
Apparently you should distrust doctors - except their doctors.
Distrust pharmaceutical companies - but not the people selling supplements and “alternative” treatments.
Question every vaccine study - but accept testimonials about ivermectin, fenbendazole, detoxes, high-dose vitamins and miracle supplements from strangers in a Facebook comment section.
And those sellers have something pharmaceutical companies could only dream of:
an army of unpaid salespeople.
Post actual medical research and watch what happens. The comments fill themselves with people enthusiastically advertising the same miracle cures, defending the same personalities, repeating the same testimonials and sending people toward the same products.
For free, with enthusiasm.
Meanwhile, the industry behind “wellness” is worth $6.8 TRILLION - nearly four times the size of the pharmaceutical industry.
Dietary supplements & alternative medicines are almost 6X the entire global vaccine market.
There is big money in medicine.
There is also staggering huge money in convincing you that medicine cannot be trusted, except their miracle cure “medicines.”
