Newly released USDA documents obtained through a Freedom of Information Act (FOIA) request are raising fresh concerns about the safety profile of America’s first widely distributed self-amplifying RNA (saRNA) vaccine for pets.
The records involve the Nobivac NXT Canine Flu H3N2 vaccine produced by Merck and marketed for canine influenza protection.
The FOIA release reportedly contains over 1,000 pages of adverse event reports submitted between September 2024 and July 2025 involving reactions observed after administration of the RNA-based veterinary vaccine.
The documents have intensified debate surrounding the rapid expansion of RNA vaccine technology into veterinary medicine following the widespread rollout of mRNA products during the COVID era.

Adverse Event Reports Include Neurological and Cardiac Cases
According to the released records, 296 adverse event cases listed the Nobivac NXT Canine Flu H3N2 vaccine as a suspect product.
The reports allegedly included:
- 152 adverse reactions
- 76 reports involving lack of vaccine effectiveness
- 41 neurological-related cases
- 30 cases involving anaphylaxis or hypersensitivity
- 52 vomiting cases
- 26 diarrhea cases
- 19 injection-site complications
- 5 collapse or shock-type reactions
The documents also reference:
- Four canine deaths
- One feline death
- Three dogs euthanized after vaccination
Officials and researchers caution that adverse event reports alone do not prove causation.
However, critics argue the reports warrant further investigation into the safety profile of self-amplifying RNA vaccine platforms in animals.
Several Cases Involved Sudden Collapse
Among the most alarming reports was a case involving a 4-year-old golden retriever that allegedly collapsed approximately 10 minutes after vaccination before suffering cardiac arrest and dying.
Another report described a 7-year-old Yorkshire Terrier that collapsed roughly 70 minutes after receiving multiple vaccines, including the RNA-based flu vaccine.
Emergency medications were reportedly administered due to previous vaccine sensitivities, but the dog later died despite treatment efforts.
A separate case involved an 8-year-old Shih Tzu that reportedly became lethargic and began vomiting shortly after vaccination before later developing renal failure and being euthanized.
Merck reportedly concluded some cases were unlikely to be directly caused by the vaccine because multiple treatments and vaccines had been administered simultaneously.

What Makes saRNA Vaccines Different?
The Nobivac NXT Canine Flu H3N2 product is the first USDA-approved self-amplifying RNA vaccine widely used in U.S. veterinary medicine.
Unlike traditional vaccines, saRNA technology is designed to:
- Deliver genetic instructions into cells
- Self-replicate inside the body
- Extend antigen production duration
- Potentially generate stronger immune responses
Supporters describe the technology as innovative and adjuvant-free.
Critics, however, argue long-term safety data remains extremely limited.
Nicolas Hulscher of the McCullough Foundation criticized what he described as limited transparency surrounding the platform’s design and safety testing.
Researchers have also acknowledged that many interactions between saRNA platforms and the body “remain insufficiently investigated.”
Additional RNA Vaccines Expanding Into Veterinary Medicine
The canine influenza vaccine is only one of several RNA-based veterinary products now entering the market.
Merck has also reportedly received approval for:
- An saRNA rabies vaccine
- A feline RNA vaccine platform
- Additional next-generation veterinary products
The company’s saRNA rabies vaccine has reportedly already become available in Canada and could eventually expand into broader U.S. veterinary use.
The rapid expansion of RNA technology into animals is drawing increasing scrutiny from veterinarians, pet owners, and independent researchers.
Debate Over Transparency and Safety Testing
Critics say portions of the USDA approval data were redacted as confidential commercial information.
However, remaining documents reportedly still referenced:
- Anaphylaxis
- Gastrointestinal reactions
- Decreased appetite
- Neurological symptoms
- Injection-site complications
The controversy comes as public skepticism surrounding pharmaceutical transparency remains elevated following the COVID-19 pandemic.
Veterinary experts continue emphasizing that post-marketing adverse event reports alone cannot establish direct causation.
Still, many pet owners are now demanding:
- Larger long-term studies
- Greater transparency
- Independent safety reviews
- Clearer informed consent regarding RNA technologies

Prophetic Context: Knowledge Increasing in the Last Days
The rapid rise of genetic technologies, biotechnology, and pharmaceutical experimentation reflects a world moving deeper into advanced scientific capabilities once unimaginable to previous generations.
In Daniel 12:4 (NASB 1995), Scripture states:
“Many will go back and forth, and knowledge will increase.”
Many Christians believe humanity is entering a period of accelerating technological transformation involving genetics, artificial intelligence, surveillance systems, and biological engineering.
While medical innovation can provide benefits, believers are also urged to exercise discernment and wisdom regarding rapidly evolving technologies whose long-term consequences remain uncertain.

Conclusion
The newly released FOIA documents involving the Nobivac NXT Canine Flu H3N2 have intensified questions surrounding the safety and transparency of self-amplifying RNA technology in veterinary medicine.
While no direct causal relationship has been officially established between the vaccine and reported adverse events, the records are likely to fuel continued debate over the rapid expansion of RNA-based medical platforms into both human and animal healthcare.
As biotechnology evolves at an unprecedented pace, calls for transparency, independent research, and long-term safety data are only expected to grow louder.
Frequently Asked Questions
What is the Nobivac NXT H3N2 vaccine?
It is a canine influenza vaccine using self-amplifying RNA (saRNA) technology developed by Merck.
What does saRNA mean?
Self-amplifying RNA vaccines are designed to replicate genetic instructions inside cells for longer-lasting antigen production.
Did the FOIA documents prove the vaccine caused deaths?
No. The reports document adverse events following vaccination, but causation has not been officially established.
What kinds of reactions were reported?
Reports included neurological symptoms, vomiting, anaphylaxis, diarrhea, injection-site reactions, and collapse-like episodes.
Are additional RNA veterinary vaccines being developed?
Yes. RNA-based rabies and feline vaccine platforms are also reportedly expanding into veterinary medicine.
After much research, the following supplements can prevent Covid and other viruses. My family and I mainly follow the protocol of Dr Bryan Ardis. This is only my opinion based on my own family’s success. Please make sure you do your own research and speak with your medical professional before making any changes to your health routine.
EDTA
Glutathion
NAC
Zinc
Vitamin C (Ascorbic Acid)
Vitamin D3
Quercetin
Cats Claw
Nicotine
Bromelain
Curcumin
Dr. McCullough recommends taking this treatment triad for at least three months for anyone suffering from or worried about post-COVID or post-vaccine syndromes.
Nattokinase, Bromelain, and Curcumin are available over the counter at just about any health food store or pharmacy.
Selenium
Dandelion Root
Black Sativa Extract (may facilitate cellular repair)
Green Tea Extract (provides added defenses at the cellular level through scavenging for free radicals)
Irish Sea Moss (could help rebuild damaged tissue and muscle)
In an acute emergency, if you get Covid, Dr Ardis suggests taking low doses of Nicotine in the form of Lozenges, Gum, or Patches for a few days until symptoms subside
