Many have argued that SARS-CoV-2 spike protein and its mRNA sequence, found in all COVID-19 vaccines, are priongenic. The UK’s Yellow Card database of COVID-19 vaccine adverse event reports was evaluated for signals consistent with a pending epidemic of COVID vaccine induced prion disease. Adverse event reaction rates from AstraZeneca’s vaccine were compared to adverse event rates for Pfizer’s COVID vaccines. The vaccines employ different technologies allowing for potential differences in adverse event rates but allowing each to serve as a control group for the other. The analysis showed a highly statistically significant and clinically relevant (2.6-fold) increase in Parkinson’s disease, a prion disease, in the AstraZeneca adverse reaction reports compared to the Pfizer vaccine adverse reaction reports (p= 0.000024). These results are consistent with monkey toxicity studies showing infection with SARS-CoV-2 results in Lewy Body formation.

The findings suggest that regulatory approval, even under an emergency use authorization, for COVID vaccines was premature and that widespread use should be halted until full long term safety studies evaluating prion toxicity has been complete. Alternative vaccines like the Measles Mumps Rubella (MMR) vaccine should be explored for those desiring immunization against COVID-19.



This is paper #2 from Classen, an immunologist and former NIH contract scientist, showing COVID injections to be extremely dangerous as they can cause prion disease. In his current paper he utilizes 6-months of UK adverse event data on AstraZeneca (uses GM adenoviruses) and Pfizer injections (uses lipid-encapsulated synthetic mRNA), whose goal is to stimulate the spike protein and antibodies, which show clear signs of causing symptoms of neurodegenerative disorders such as Parkinson’s, Alzheimer’s ALS, and others.  

The study showed nervous disorders, tremors, and sleep disturbances, after the COVID injections – all of which are symptoms of prion disease.  

Classen is concerned because the reporting system is set up to report acute events, not neurodegenerative issues, which can be non-specific or overlap with other conditions, which could occur years or decades later.  Due to this, findings could be exponentially higher.

Paper #1 which analyzed the Pfizer injection is here and points out many important details to consider, including an important excerpt from the summary:

Many have raised the warning that the current epidemic of COVID-19 is actually the result of an bioweapons attack released in part by individuals in the United States government [10,11]. Such a theory is not far fetched given that the 2001 anthrax attack in the US originated at Fort Detrick, a US army bioweapon facility. Because the FBI’s anthrax investigation was closed against the advice of the lead FBI agent in the case, there are likely conspirators still working in the US government. In such a scenario the primary focus of stopping a bioweapons attack must be to apprehend the conspirators or the attacks will never cease. Approving a vaccine, utilizing novel RNA technology without extensive testing is extremely dangerous. The vaccine could be a bioweapon and even more dangerous than the original infection.

Important excerpt:

This analysis should serve as an urgent warning to those mindlessly following advice of politicians and public health officials regarding COVID immunization. Both groups have had a dismal record of protecting the health of the public. US public health officials ran the infamous Tuskegee syphilis study allowing people of color to die from syphilis because the public health officials refused to inform the patients, they had syphilis and that a treatment existed. There have been numerous less well-known experiments on prisoners and other vulnerable populations in North America. The infamous Nazi physician Josef Mengele was a public health doctor.

5 doctors state the injections are bioweapons & what you can do about it. The injections are NOT “vaccines” but cause YOU to manufacture spike proteins – perhaps indefinitely – the very thing causing illness. Those getting the injections are possibly transmitting this spike protein to those foregoing the injections.
