Vaxxed vs Unvaxxed Neurodevelopmental Outcomes in COVID Jabbed Children

Please remember, the COVID injections are NOT vaccines. They are a gene therapy developed by the military that have never protected against infection or transmission. They weren’t even tested for reduction in hospitalization, death, or transmission. They were tested for reduction in severe symptoms – which is not the proper endpoint for “vaccine” efficacy. The public, which has served as subjects in an ongoing clinical trial for an experimental mRNA platform never before used in humans, that scientists have admitted have toxicity risks, is suffering from catastrophic injuries and death, but ‘the powers that be’ simply target those for speaking the truth: the COVID shots are killing people.

Neurodevelopmental Outcomes in COVID-19-Vaccinated Versus Unvaccinated U.S. Children: Analysis of the National Health Interview Survey, 2022–2024

Authors/Creators
Description
Abstract

Background: Autism spectrum disorder now affects 1 in 31 U.S. 8-year-olds and continues to rise at an alarming rate. COVID-19 mRNA vaccines were first authorized for U.S. children aged 12–15 in May 2021, 5–11 in October 2021, and 6 months–4 years in June 2022. No pediatric trial or post-marketing surveillance study was designed or powered to detect neurodevelopmental or mental-health outcomes after childhood COVID-19 mRNA vaccination. Vaccine-derived spike protein circulates systemically after vaccination and has been detected in blood, monocytes, cerebral arteries, and peripheral tissue months to years later, the S1 subunit disrupts blood–brain-barrier integrity in vitro, and prenatal spike-protein exposure induces autism-like behavior, neuroinflammation, and reduced BDNF in male rats. A population-level signal-detection analysis is warranted.

Methods: We pooled the 2022–2024 National Health Interview Survey (NHIS) Sample Child files (n = 21,990 children aged 0–17 with COVID-19 vaccination status; n = 19,882 aged 2–17 for autism, ADHD, and learning-disability items; 844 lifetime and 779 current ASD cases), with the 2021 (ages 12–17) and 2025 (current-season dose) files as supplementary samples. The primary comparison was COVID-19-vaccinated versus COVID-19-unvaccinated children (parental report of ever receiving a COVID-19 vaccine; “unvaccinated” denotes no COVID-19 vaccine, not absence of routine childhood immunization), with number of doses and years since first dose as secondary exposures. Outcomes were parent-reported lifetime and current autism spectrum disorder (ASD), ADHD, learning disability, intellectual disability, developmental delay, special-education use, asthma, diabetes, anxiety and depression frequency, mental-health treatment, general health, and acute-care use. Influenza and HPV vaccination served as negative-control exposures. Survey-weighted logistic regression with stratum/PSU Taylor-linearized variance estimated odds ratios (ORs) across five adjustment tiers.

Results: Compared with unvaccinated children, COVID-19-vaccinated children had higher adjusted odds of lifetime ASD (aOR 1.26, 95% CI 1.04–1.52), current ASD (1.32, 1.08–1.60), ADHD (1.33, 1.18–1.49), any neurodevelopmental diagnosis (1.23, 1.12–1.35), special-education use (1.19, 1.08–1.31), asthma (1.24, 1.11–1.37), daily/weekly anxiety (1.27, 1.15–1.42), and mental-health medication (1.57, 1.38–1.77) and therapy (1.60, 1.43–1.79); the E-value for current ASD was 1.97, and no measured covariate was associated with both vaccination and autism in the same direction at this magnitude. Adjusted odds rose monotonically with dose count (current ASD 1.03, 1.25, 1.40 for 1, 2, ≥3 doses vs 0). The association (current ASD) was largest in the youngest exposed cohort: ≥3 doses vs 0 at ages 5–7, aOR 2.54 (1.33–4.84); ages 2–7, 2.37 (1.38–4.10); and among children first vaccinated at age ≤5 at least one year before interview, 2.46 (1.08–5.62; 9 exposed cases). Under propensity-score overlap weighting, which eliminated all measured covariate imbalance, the autism association was unchanged and remained significant (lifetime 1.23, 1.01–1.50; current 1.26, 1.03–1.56), while the negative-control outcomes of emergency-department visits and hospitalization were close to the null (0.95 and 1.02). Estimates were unchanged after restriction to children without asthma, diabetes, or fair/poor health (n = 16,803; both vaccines vs neither, 1.51, 1.17–1.95), and persisted after additional adjustment for emergency-department use, hospitalization, and prescription use (1.31, 1.04–1.66). In direct comparison, COVID-19-vaccine-only children (n = 3,205) had higher odds of ASD than influenza-vaccine-only children (n = 3,763; 1.45, 1.03–2.05) despite lower odds of asthma (0.73) and emergency-department visits (0.77). Anxiety showed partial specificity (COVID-19 vaccine 1.34 vs influenza vaccine 1.07 at ages 5–11). Against the unvaccinated reference; however, influenza-vaccine-only and COVID-19-vaccine-only, point estimates were similar and modest (1.11 and 1.12) for ASD. Likewise, HPV vaccination was modestly associated with ASD 1.17 (0.74–1.85). The ASD association was amplified among children receiving both (influenza and COVID-19) vaccines (1.42–1.51). Associations for current ASD weakened with time since first dose, and the COVID-19 vaccine association was confined to girls (1.60 vs boys 1.08; interaction p = 0.02).

Conclusions: In a direct comparison of COVID-19-vaccinated with unvaccinated children in a nationally representative U.S. sample, COVID-19 vaccination was associated with higher adjusted odds of autism, ADHD, anxiety, special-education use, and mental-health treatment. The autism association persisted across every adjustment tier; was unchanged under propensity-score balancing that removed all measured covariate imbalance and nullified the acute-care negative controls; was robust to restriction to physically healthy children; increased monotonically with dose count; was largest in the youngest exposed cohorts, including children vaccinated before the school-entry diagnostic window; and exceeded that of influenza vaccination in direct comparison. These properties satisfy the strength, consistency, biological gradient, plausibility, and coherence considerations for causal inference, and no measured confounder explains them. Because the cross-sectional design cannot order exposure and diagnosis, a global scheduled combination childhood vaccine effect on neurodevelopment cannot be evaluated. A linked birth-cohort study of toddlers before age 3 capturing co-administered vaccines, incident diagnoses, and pre-specified negative controls would be the next step in evaluating this concerning association.

October DOJ Report Exposing the Existing Machine to Treat You As A Terrorist Threat

**UPDATE**

The U.S. Department of Health and Human Services (HHS) states in its September 9, 2026, shutdown contingency plan that its pandemic preparedness agency will suspend Freedom of Information Act (FOIA) execution and congressionally mandated preparedness evaluations while continuing to negotiate, award, and manage biodefense contracts. You can contact HHS here.

They Built a Machine to Treat You as a Terrorist Threat. The Justice Department Just Published the Blueprints.

Five years ago I warned that the government was preparing to treat people who questioned COVID policy as a domestic-terror problem. The receipts are in.

Five years ago I warned that the government was preparing to treat people who questioned COVID policy as a domestic-terror problem. A 273-page DOJ report, released October 5, 2026, now shows exactly how it was done, who was targeted, and why it should matter to every reader of this newsletter.

On August 13, 2021, the Department of Homeland Security issued a terrorism bulletin that listed “grievances over public health safety measures and perceived government restrictions” among the drivers of domestic terrorism, and promised to “identify and evaluate” online activity “associated with the spread of disinformation, conspiracy theories, and false narratives.”

The next day I published a piece on GreenMedInfo saying plainly what the bulletin implied: that people who questioned, resisted, or disobeyed COVID restrictions, or who questioned the vaccines, were being moved into the category of potential domestic terrorists. I wrote that the people being described this way were mostly mothers and fathers, many with vaccine-injured children, who were questioning the medical system for the first time in their lives.

I was told that was paranoid. And that I was a “super-spreader” of dangerous misinformation.

On October 5, 2026, the Department of Justice released a report by its Weaponization Working Group, with 250 pages of internal emails attached, showing what happened in the ten weeks after that bulletin. I have reviewed all 273 pages. This is what they say, in plain language, and what it means for you.

The machine is not partisan and it is not gone. Tip portals, threat tags, private “NGO reporting” contracts, and counter-misinformation offices are infrastructure. They outlive the administration that built them. The only reason we can read these emails is that one administration chose to release documents about the previous one. The next one can choose otherwise. (See link for chronology as well as steps that need to be taken)

**Comment**

Ji says the following steps are crucial so history doesn’t repeat itself:

  • Extend the file review and apology process to ANYONE whose name is on the ‘naughty’ list.
  • Release the communications.
  • Make it illegal to rebuild. The Senate Commerce Committee has already advanced S. 4749, the JAWBONE Act, which would bar federal officials from coercing platforms to suppress lawful speech. Call your senators and ask them to pass it. Then ask your representative for a House companion. Restore the First, has scripts and a lookup tool.
  • Join Stand For Health freedom and take action with their advocacy tools. And share the platform widely with those you know who are.
  • Pre-order Ji’s upcoming investigative book, Shadow Empire: The Epstein Files, to educate yourself on how the systems of power that operate with impunity expose themselves in the 3.5 million document release from Jan. of this year. Ji recently reported on Epstein’s plan to create a “Mother’s Army” to target their children for vaccination directly. The truth must get out.

USDA Ordered 6 M Doses of ‘Experimental’ Plague Vaccine & Russia Plague Mystery: Separating Fact From Hype

**UPDATE**

I encourage you to read Sayer Ji’s article: The Plague Panic & Vaccines Were Ready Before the Diagnosis. In it you will learn that within 72 hours of a Siberian lab worker dying without a plague diagnosis, vaccine stocks shot up 20%, proving a fear narrative and countermeasure economy are fully built and waiting to be set in motion at any time by an unresolved death, long before any evidence. This is what should frighten you.

Russia Plague Mystery: Separating Fact From Social Media Hype

IMA’s Dr. Ryan Cole says Russia’s suspected plague death is unconfirmed and not an outbreak. After COVID, Americans should demand evidence before fear.

Independent Medical Alliance

October 8, 2026

IMA Head of Medical and Scientific Affairs Dr. Ryan Cole joined The National News Desk to separate fact from fiction in reports of a suspected plague death in Russia. A young woman who worked at a plague research laboratory in Siberia died after developing severe pneumonia, but testing has not confirmed plague. Dr. Cole explains that the story first spread through a Telegram channel, and that 90% of the roughly 200 people placed under observation have already been released. One death, he notes, does not make an outbreak.

Dr. Cole also takes on social media posts linking the case to an experimental mRNA plague vaccine, which he points out has only been studied in animal models. He explains that pneumonic plague rarely spreads from person to person, is treatable with antibiotics when caught early, and circulates on every continent except Australia among rodents and fleas most people rarely encounter. Looking back at COVID, when conclusions were drawn before the evidence was in, he urges Americans to demand evidence before believing a viral headline.

USDA Ordered 6 Million Doses of ‘Experimental’ Plague Vaccine the Same Month DEFUSE Proposed Spraying Its Carrier on Bats

The order was six times existing demand and equal to nearly 28 years of later annual bait sales, while DEFUSE-linked spray technology identified applications for “animals/humans.”

Jon Fleetwood

Oct. 8, 2026

USDA-APHIS procurement memorandum dated March 6, 2018, specifying 6 million doses of experimental recombinant raccoonpox vaccine (RCN-F1-V307), valued at $1.3 million, for manufacture into plague-vaccine bait for prairie dogs at the USDA Pocatello Supply Depot in Idaho. The document predates the April contract award and was prepared the same month Project DEFUSE was submitted to DARPA.

According to a March 2018 U.S. Department of Agriculture Animal and Plant Health Inspection Service (USDA-APHIS) contract award to Colorado Serum Company, the federal government contracted for an estimated 6 million doses of recombinant raccoonpox plague vaccine, using the same vaccine-carrier platform Project DEFUSE proposed that month for spraying vaccine material onto bats.

The plague-vaccine order was six times the doses USDA said it needed for existing customers and equivalent to nearly 28 years of the depot’s subsequently reported annual vaccine-bait sales.

Meanwhile, DEFUSE’s proposed delivery partner, PARC, described aerosol technology for biological applications involving “animals/humans.”

DEFUSE is the project submitted the year before the COVID-19 pandemic to the Defense Advanced Research Projects Agency (DARPA) that characterized a pandemic response to a future SARS-CoV-2-like outbreak.

  • Why was the government contracting for millions of doses of a plague-vaccine platform while developing automated biological spraying?
  • What would be sprayed, and what informed consent protections would exist for potentially exposed people?

Splitting Up the Combination Vaccines

https://thevaccinereaction.org/2026/09/splitting-up-the-combination-vaccines/

Splitting Up the Combination Vaccines

by Marco Cáceres

Published September 28, 2026

Opinion

Splitting Up the Combination Vaccines

President Trump announced on Sept. 18, 2026 that his administration plans to recommend that certain childhood vaccines be split up into separate shots. The policy proposal is apparently a follow-up to an Executive Order the President signed on Aug. 10 that calls for recommending the number of diseases for which children should be vaccinated be reduced from 17 to 11, including measles, mumps, rubella, diphtheria, tetanus, pertussis, polio, Haemophilus influenzae type B, pneumococcal disease, human papillomavirus, and varicella.1 2 3 Trump said:

Instead of a child going in and having a tremendous amount of different vaccines pumped into a big proportion of the body … we’re going to recommend that they do five doses marked one, two, three, four, five and that they be given in six-month intervals, so that a small amount of the vaccine gets pumped into the body.1 2

MMR Could Be First to Be Targeted

A likely combination vaccine that could be separated into individual shots would be the live attenuated MMR vaccine, a three and four-vaccine combo shot in the form of the MMR (measles, mumps, and rubella) and MMRV (measles, mumps, rubella, and varicella) vaccines.

Last month’s Executive Order actually specified that the MMR vaccine be broken up and be administered as separate shots. The MMR, either Merck’s M-M-R II product or GSK’s Priorix, are recommended for children 12-15 months old (first dose) and 4-6 years old (second dose). Breaking up the vaccine would mean giving three shots (one each for measles, mumps, and rubella) instead of one combo shot for the first dose and three shots again instead of the combination MMR shot for the second dose.3 4

There is another combo shot on the U.S. Centers for Disease Control and Prevention’s (CDC) childhood vaccination schedule—the DTaP (diphtheria, tetanus, and acellular pertussis). There are two DTaP combo vaccines licensed in the United States—Sanofi Pasteur’s Daptacel and GSK’s Infanrix. The DTaP shot is recommended to be given five times. The first shot at two months of age, the second at four months, the third at six months, the fourth between 15 and18 months, and the fifth between 4 and 6 years. Breaking up the vaccine would mean, again, giving three shots (one each for diphtheria, tetanus, and pertussis) instead of one combo shot for each of the five doses.5 6 7 8

There are five other combo vaccines licensed in the U.S. that include the DTaP—Kinrix, Quadracel, Pediarix, Pentacel, and Vaxelis. GSK’s Kinrix and Sanofi Pasteur’s Quadracel each add the inactivated poliovirus vaccine to make them four-vaccine combos. GSK’s Pediarix adds the hepatitis B and inactivated poliovirus vaccines, making it a five-vaccine combo. Sanofi Pasteur’s Pentacel adds the inactivated poliovirus and Haemophilus influenzae type b vaccines for another five-vaccine combo. Lastly, Merck/Sanofi Pasteur’s Vaxelis adds the inactivated poliovirus, hepatitis B, and Haemophilus influenzae type b vaccines for a whopping six-vaccine combo.9

There is also the Tdap (tetanus, diphtheria, and acellular pertussis) vaccine), and one dose is recommended for children between 11-12 years old.10

Safety of Combo Vaccines a Concern

Combination vaccines, particularly the combination diptheria-tetanus-pertussis and measles-mumps-rubella vaccines have been used for decades since the mid-20th century. If vaccine manufacturers agree to produce separate vaccines and the CDC officially recommends their use, this policy shift would represent a major reversal in the growing trend toward the development of more and more combo shots containing multiple vaccines.

An article by guest writer Sheri Marino republished in The Vaccine Reaction noted, “While the CDC suggests that combination vaccines are safe, research shows there are more adverse events, such as febrile seizures, with combination vaccines than there are for single vaccines.” Marino added, “Research published in the New England Journal of Medicine revealed a significantly elevated risk of febrile seizures 8 to 14 days after administration of the MMR vaccine.”11

Marino continued:

According to the CDC, pre-licensing data obtained from the Vaccine Safety Datalink, reveals the MMRV vaccine shows recipients were twice as likely to have febrile seizures than those injected with the MMR and Varicella vaccines separately. Another study conducted in Denmark published in the Journal of American Medical Association demonstrated that the 5 valent DTaP-IPV-HIB vaccine has been linked with increased febrile seizures.11

Deadly COVID Hospital Protocol Exposed Yet Again in Senator Johnson’s Roundtable

COVID Hospital Protocols: ‘This Kind of Cruelty Will Not Be Repeated’

Witnesses at Sen. Ron Johnson’s roundtable today described patients separated from loved ones, treatment decisions made without family consent and medical professionals who said they faced pressure when they challenged hospital protocols. “Today I am providing a platform for these stories to be told so that this kind of cruelty will not be repeated,” Johnson said.

During Sen. Ron Johnson’s (R-Wis.) roundtable on COVID-19 hospital care today, Brad Seiler described the desperate effort to get his wife, Gail, out of a hospital after staff told him she was “unsavable.”

When Brad finally got her discharged, he said hospital staff wouldn’t let them leave through the main entrance. Instead, Gail was taken down a freight elevator used to transport bodies to the morgue and escorted out through doors used by funeral homes.

A nurse told him, “She’ll be dead tonight, or before you even get home.” Gail survived.

“Today, Gail is alive, healthy, active, and enjoying life with our grandchildren and children,” Seiler said.

Seiler was one of 21 patients, family members, doctors and nurses who testified at the “COVID-19 Hospital Protocols: Real Stories from Real People” roundtable. Johnson said that as of Sept. 26, his office had received 583 testimonies from people in 46 states.

“Today I am providing a platform for these stories to be told so that this kind of cruelty will not be repeated,” Johnson said.

**Comment**

This is not the first time the ‘Fauci death protocol’, which caused nearly half a million excess deaths, as been exposed. Many doctors and nurses who existed mainstream health care have described the ‘Brutal’ COVID protocols in full to anyone with a listening ear.

Sadly, as well intentioned as Senator Johnson is, the cruelty experienced during the COVID years is doomed to be repeated due to the still intact PREP-Act which overrides medical freedom, including informed consent, free speech, parental rights, religious freedom, and privacy. This liability shield remains intact for specified covered countermeasures and qualified persons, including licensed pharmacists, pharmacy interns, and qualified pharmacy technicians administering COVID-19 vaccines to individuals aged three and above through December 31, 2029.

Journalist James Roguski has worked tirelessly to Repeal the Unconstitutional PREP Act and Ban Medical Mandates, making murder a crime again.

BREAKING: Dr. James Miller EXPOSES the Hospital Protocol Murder Machine and the Plan to Eliminate the Rights of the Unvaccinated

Testifying before Senator Ron Johnson, a trauma surgeon blows the whistle on falsified death counts, deadly protocols, and the state-backed plot to restrict the civil rights of the unvaccinated people

Lioness of Judah Ministry

Sept. 28 2026

Dr. James P. Miller, a trauma and ICU surgeon, conducted formal quality reviews that exposed rampant administrative fraud directly responsible for patient harm and skyrocketing mortality.

Senior hospital executives deliberately pushed toxic protocols like Remdesivir using false and misleading data, locking patients into lethal treatment tracks while silencing frontline dissent.

While corporate media broadcast images of overflowing wards, the lived reality inside the hospital was empty beds and nurses sent home for lack of work. Trauma and other non-COVID fatalities were systematically falsified on death certificates as COVID-19 to inflate the casualty count and terrorize the public.

The hospital head of infectious diseases openly admitted to Dr. Miller that leadership was coordinating directly with state officials to strip unvaccinated citizens of their basic civil rights, culminating in an outright institutional refusal to treat unvaccinated patients.

“The head of infectious disease medicine at my hospital privately told me that he was working with the state government to restrict the civil rights of unvaccinated people.” — Dr. James P. Miller, MD

**Comment**

It’s important to note and appreciate that due to the medical tyranny Dr. Miller opened a free clinic through his church where he successfully treated many Covid patients with zinc, quercetin, ivermectin, and HCQ. For saving lives he was rewarded with having to endure YEARS of disciplinary and legal action, with the goal of taking away his medical license. He was one of the few doctors who spoke the truth when most of his colleagues remained silent.

I just learned that attorney Ralph Lorigo spoke at the Roundtable and stated that he represented 212 legal cases. In 72 cases, he successfully got Ivermectin administered to the patient. Of those 72 patients, he said only 3 died—a 95.8% survival rate. He won additional cases in which ivermectin ultimately was not administered despite the court action. Of the remaining 140 cases that could not get into court quickly enough or lost his effort to obtain the treatment, he testified that every single patient died.

COVID tyranny was complete.

According to retired New York University Professor of media studies Mark Crispin Miller, COVID was a ‘propaganda masterpiece.’

In January of 2026, we learned through FOIA records that U.S. federal intelligence agencies classified and redacted the results of an internal review of COVID-19 PCR test primers, even as those tests were used to define “cases,” drive emergency policy, and justify unprecedented social and economic controls.

Folks have been screaming about the inaccuracy of using PCR, which can’t distinguish between a virus and death, harmless viral fragments, for years. In fact, one study found only 14% of PCR “COVID cases” were real, proving that lockdowns, masking, ‘vaccine’ mandates, were all built upon a fraudulent testing illusion. Italy reduced it’s COVID death number by 97% due to the high cycle threshold values utilized that led to soaring false positives. A Portuguese court ruled that PCR tests are unreliable and unlawful to quarantine people based solely upon them. A study determined way back in 2020 that the false positive rate using PCR for COVID is 97%.

Our public health ‘authorities’ meanwhile peddled fear by stating the asymptomatic were “silent carriers” and pushed people to test more frequently, and agree to get the completely worthless, experimental, fast-tracked, dangerous COVID gene therapy injections that actually make it more likely to contract COVID, just like the flu vaccine puts you at higher risk for COVID and other respiratory viruses. They are currently doing it again with asymptomatic bird flu and are prepping a shot for humans “just in case.”

It’s always about a lucrative ‘magic bullet’ vaccine that never lives up to the hype, and has been proven to contain 55 undeclared chemical elements, Green monkey DNA, metals including graphene, PEG, lipid nanoparticles, black particles, white floating and other foreign matter, human fetal cell lines, and dangerous endotoxins hidden from testing. U.S. officials knew the injection safety system was flawed but ignored warnings.

Then, public health ‘authorities’ grossly inflated COVID mortality. A 2025 update showed nearly half of COVID deaths were not due to COVID. Countless patients and advocates have spoken out on the unbelievable injustice they were forced to endure due to the unconstitutional and fraudulent measures imposed upon them, which sometimes resulted in their untimely death.

Then, grossly inflated cases and morality were justified for an ineffective gene therapy injection that continues to maim and kill people. They also censored and maligned any doctors and treatments that competed with this lucrative but ineffective injection.

As a result of all these findings, Senator Johnson connected with Canadian MP Chris Lewis to discussed alleged COVID-19 vaccine side effects and “turbo cancer” claims at the Allison Inquiry in Canada, and the IMA is calling on the CDC to immediately withdraw ‘off label’ COVID ‘vaccine’ recommendations.

Pandemic ‘leaders’ were biodefense puppets and profiteers who did not make ‘mistakes,’ but actually planned it all with purpose.
