Immunologist warns Pfizer and Moderna coronavirus vaccines may cause neurodegenerative disorders
Immunologist J. Bart Classen warns that the Pfizer-BioNTech and Moderna vaccines for COVID-19 can potentially cause neurodegenerative disorders, such as Alzheimer’s disease.
In a paper published in the journal Microbiology & Infectious Diseases, Classen reported that mRNA-based vaccines like the two jabs can misfold proteins in the body that are linked to the development of neurodegenerative disorders.
After sampling the Pfizer-BioNTech vaccine and analyzing its RNA sequences, he identified several sequences that can misfold certain proteins in the body. When misfolded, these proteins can potentially cause Alzheimer’s, amyotrophic lateral sclerosis(ALS) and other neurodegenerative disorders, according to Classen.
He also said that mRNA-based vaccines may cause several more adverse events, such as infections that are more serious than COVID-19. Because the vaccine places the spike protein on the surface of human cells, according to Classen, it may serve as a receptor for other foreign pathogens.
Unfortunately, he continued, data about how long the spike protein will be present on human cells is not publicly available. (Related: Why is the CDC withholding critical covid-19 vaccine safety data from the public?.)
Many researchers have identified potential long-term risks to mRNA-based vaccines. According to an article published in May last year in the journal Medical Science Monitor, these risks include the possible development of autoimmunity (where the immune system attacks the body’s own tissues) and the toxic effects of the vaccines’ components including the RNA sequences.
Though the Pfizer-BioNTech and Moderna vaccines already rolled out in many countries, their long-term side effects are not yet well-established. The adverse reactions that experts are aware of are short-term side effects.
