Andrew Wakefield’s fraudulent paper on autism and vaccines had 12 (twelve) children in it.
The studies that followed had millions.
And showed no link

The evidence that vaccines don’t cause autism is overwhelming. Also there’s the absence of a plausible mechanism for a vaccine link given that autism begins in early fetal development through the action of >100 autism genes. The vaccine-autism link is entirely fabricated by individuals and groups with self-serving agendas. Here’s my latest paper from @BakerInstitute bakerinstitute.org/research/…
At a federal autism advisory committee meeting yesterday, committee members explicitly named vaccines as a cause of autism — despite years of scientific evidence debunking any link between the two.

Let's set the record straight because @RobertKennedyJr’s post is inaccurate and misleading and he is making claims that have been debunked repeatedly by actual scientists and doctors.
Secretary Kennedy called me yesterday morning to ask whether Pennsylvania needed any additional support to respond to the measles outbreak. I told him I appreciated the call but that our Administration and the Pennsylvania Department of Health had all the resources we needed to respond, including existing support from professional staff at the CDC and HHS.Â
I told him what would be most helpful is if he would join me in encouraging people to get vaccinated and stop spreading misinformation. He then launched into a tirade — talking about fetal tissue and blaming the previous Administration for this problem. He even told me it would be better if we went back to “natural measles.”
Unfortunately at a time where I needed the top “health expert” in the nation to responsibly work with us to deal with this outbreak, he instead chose to go down a rabbit hole of conspiracy theories and false claims.
To his claim about fetal tissue, that has been thoroughly discredited time after time by real doctors and trusted medical institutions like CHOP. In fact, the American Academy of Pediatrics has an entire webpage devoted to this.
They write: “Vaccines do not contain fetal cells. Some vaccines involve growing viruses in human cell cultures originally developed from two aborted fetuses in the 1960s. These cell lines are still going, so no new aborted fetuses are ever needed. Purification processes filter the vaccine during production, and no fetal tissue remains.” Â
But my conversation with him proved what many of us already knew:Â
Secretary Kennedy’s actions to dismantle public health agencies and his language that undermines confidence in vetted medical guidance are contributing to these kinds of outbreaks.Â
Just a few years ago, Secretary Kennedy was in Lancaster downplaying the severity of measles and saying that the cure was “chicken soup and vitamin A.”
Before he held his current position, measles was virtually eliminated in the United States. As recently as 2024, there were only 285 cases of measles across the entire country over 12 months. This year, in just 8 months, there are nearly 400 cases of measles across 29 counties in Pennsylvania alone — and nearly 3,000 cases across the country.Â
In Pennsylvania, 70 people who have tested positive for measles have been hospitalized this year — and yesterday, our @PAHealthDept announced that two Pennsylvanians who tested positive for measles have died.
According to doctors and medical experts, the MMR vaccine is the best way to protect yourself, your kids, and your community against measles. But we have seen vaccination rates decline on RFK’s watch.Â
The correlation is clear: Secretary Kennedy has stoked confusion amongst parents and others — and the result has been less protection from measles and more cases.
As a dad, all I want is to protect our four kids. I know that’s how every parent feels. Parents have the right to make their own decisions about how to keep their kids safe and sort through the noise to figure out which information to trust.Â
So what I’d ask of every parent in Pennsylvania: take any information you get about vaccines and talk to a trusted health care provider about it before you make your decision.
The most important conversation that needs to take place now is one that should happen offline, in the real world, between parents, their trusted health care providers, and other medical experts.
Replying to @RobertKennedyJr
At his press conference today, Pennsylvania Governor Josh Shapiro accused me of promoting conspiracy theories because I told him, during an earlier telephone conversation, that some Americans had religious objections to the MMR vaccine because it contained fetal tissue. “There is no fetal tissue in the MMR,” he told me.
This is a segment from a videotaped deposition of Stanley Plotkin, the inventor of the MMR vaccine. Plotkin admits to butchering 76 aborted normally developing fetuses, all over three months old, in just one of the many studies that led to the development of his vaccine.
The rubella virus used in MMR-II is grown on the cultured cell line composed of lung tissue from an aborted three-month-old female embryo and listed as “WI-38 human diploid lung fibroblasts” in the ingredients of MMR-II as portions of these cells end up in each vial of MMR II.
During Dr. Plotkin’s deposition, Attorney Aaron Siri asked: “Isn’t it true that MMR II contains approximately 150 nanograms cells substrate double-strand DNA and single-strand DNA per dose purposefully fragmented to approximately 215 base pairs in length?” Dr. Plotkin answered: “Yeah, that’s probably correct, yes.”
This equals approximately 646 billion pieces of human DNA from an aborted fetal cell line in each vial of MMR-II.
In addition to the human DNA, there is also an unspecified amount of human cellular debris in each dose of MMR-II.
During our phone conversation, Governor Shapiro also accused me of promoting vaccine misinformation. When I asked him for an example, he was unable to provide one, but this did not deter him from publicly repeating that accusation during his press event. As I told him, HHS does not tolerate misinformation by any employee. I offered to point to hundreds of instances of vaccine misinformation by the Biden administration about which I had never heard him complain.
Governor Shapiro also faulted me for the decline in Pennsylvania vaccination rates from 97% - 93.2%. When I pushed back on this assertion, he acknowledged that most of the decline occurred during the Biden administration. It’s unfortunately true that the government lockdowns, deceptions, manipulation, and overreach during Covid severely damaged public faith in the vaccine program.
Governor Shapiro’s press conference was an example of the same species of gaslighting.
The Trump administration is working to restore public trust not by gaslighting or manipulating, but by being truthful, at last, with the public.

This is the thing: measles is the canary in the coal mine. It’s the most contagious disease we know, so it’s the first to come back when vaccination slips, and behind it are diphtheria, polio, whooping cough, all the diseases we no longer fear because we stopped seeing them.
Measles is like the bright dye that plumbers flush through pipes to find leaks in a complex system, writes @SheInvestigates.
The continued appearance of the virus warns of cracks in our once-solid protection.

This remains one of the most bizarre cancer myth and RFK Jr. fairytale at the same time: No, Wi-Fi radiation does not cause cancer.
Phone/Wi-Fi radiation is non-ionizing, it can't break DNA, so it can't cause cancer.
Aside from that physics fact: glioblastoma rates stayed flat for decades while phone use exploded.
And the court rule btw stated that the FCC didn't adequately explain its safety limits, not that phones cause cancer. That's the trick: a procedural win sold as proof.
All the Russia claims are obviously total and utter nonsense. Put your phone where you want at night, just don't believe you are decreasing your cancer risk by doing so.
It is ironic by itself that the post complains about funding for "research" into that got cut off, while in reality serious cancer research has seen a tremendous cut while RFK Jr. is in charge. For bs like this.

🚨🚨 Robert Kennedy Jr. acaba de revelar que la radiación Wi-Fi causa cáncer...
Lo dijo en el programa de Joe Rogan y representa a cientos de pacientes que tienen tumores cerebrales causados ​​por ello...
Los tumores son glioblastomas, una de las formas más letales de cáncer cerebral...
Kennedy afirma que siempre aparecen en el mismo lado de la cabeza, donde el paciente sostenĂa el telĂ©fono...
Pero el cáncer ni siquiera es el peor efecto...
Kennedy afirma que la radiación Wi-Fi abre la barrera hematoencefálica, permitiendo que todas las toxinas presentes en el cuerpo pasen al tejido cerebral:
• Glifosato procedente de los alimentos
• Microplásticos procedentes del agua
• Retardantes de llama en los muebles
Los investigadores que publicaron estos hallazgos lo denominaron "cerebro permeable". El gobierno estadounidense respondiĂł suprimiendo la investigaciĂłn y suspendiendo la financiaciĂłn.
Kennedy afirma que decenas de miles de estudios documentan el peligro.
Rusia desarrollĂł la radiaciĂłn Wi-Fi como arma. Las escuelas rusas prohĂben los telĂ©fonos mĂłviles. Los niveles de radiaciĂłn permitidos son una Ănfima parte de los que permite Estados Unidos.
Kennedy demandĂł a la FCC por este motivo. El tribunal fallĂł a su favor.
Sus recomendaciones:
• Nunca duermas con el teléfono cerca
• Nunca sostengas tu teléfono contra tu cabeza
• Nunca lleves el teléfono en el bolsillo del pecho.
La ciencia existe. El gobierno optĂł por ocultarla...

It is not true that the miscarriage rate for vaccinated women was 82%. People are just misreading the study results.
The 82% number was the percentage of pregnancies that ended in the first trimester that were miscarriages. Obviously, miscarriage is the most common way a pregnancy is going to end in the first trimester, so this number is not notable whatsoever.
The denominator of the fraction was not "total pregnancies", it was "pregnancies that ended in the first trimester."
There are countless studies that have proven the vaccine did not cause a higher than normal rate of miscarriages.
Beyond the math and the papers, you can also just use common sense. There are roughly 3.5 million babies born in America every year. Around 70% of American women of child-bearing age got the COVID vaccine.
If the miscarriage rate for vaccinated women were 80+%, that would mean a majority, close to 2/3rds, of pregnant American women miscarried during COVID.
In reality, we can see that the number of births happening in America has been totally flat since the years preceding the pandemic.
Unfortunately, this nonsensical misinformation is going to take hold across broad swathes of the American right because people are either ignorant, panicked, or lying about it.

Today @WhiteHouse said the 2024 childhood schedule contained 84 vaccine doses. At the same event, Trump said 72. @SecKennedy said 94.
How do they get 84?
36 are annual flu and COVID doses projected out to age 18.
18 are COVID doses, a recommendation this administration itself ended. They inflated the number with a vaccine they removed, then used it to justify removing more.
And the HHS assessment counts one MMR injection as 3 doses, 1per disease. So splitting MMR doesn't cut their tally by a single dose. Same 6 doses, so 6 shots instead of 2.
They built a number that can't be lowered by the policy it was built to justify.

The stunning thing about this pile-on re: Fauci by a handful of GOP senators is the total lack of interest by these supposedly outraged senators at the person who had the power at the time.

There is no evidence sunscreen causes cancer. None. The link between unprotected sun exposure and skin cancer, all types, is one of the most well-established findings in oncology.
On the contrary: One of the largest randomized trials ever done on this found zero harmful effect from daily sunscreen use, and a real reduction in squamous cell carcinoma.

False, unless you mean “cured” = 100% of people fully and immediately cured which is a crappy definition of cured
Many diseases that were nearly always fatal are now treatable and some curable with normal life expectancy
Some examples:
1. chronic myeloid leukemia : before targeted therapies discovered in 2001 many patients lived only a few years now many have normal life expectancy
2. Hepatitis C: before 2011-2014 treatments worked for very few patients while new treatments cure more than 95% of patients within 2-3m
3. HIV/AIDS was a death sentence jn the 1980s-1990s, but now with treatment many live a normal life span
4. Cystic fibrosis: in 1980’s life expectancy was mid teens, then with breakthroughs by 2010 it was 35-40yrs and now 65-66yrs, almost full life span
5. Metastatic melanoma: before immunotherapy in 2011 median survival was 6-9m with only 2-6% alive in 5yrs — now 35-40% alive at 5yrs and some immunotherapies have found half surviving 10yrs or more
6. Spinal muscular atrophy: before 2016, median survival 6-10m and 90% dead or on permanent ventilator by 2 yrs — now with new treatments >90% are alive and ventilator free at 2yrs, and many are surviving beyond childhood — with long term survival limits still undefined and growing.
If you are trying to say the biomedical research community has not had any disease treatment breakthroughs in the last 2 decades, you are simply wrong, as there are many breakthroughs including these and many others also with dramatic improvement.
That is a false narrative driven by politics, not the actual scientific results
