Covid Vaccines Cause ‘Autism’ in Lab Rats, Study Finds


by Igor Chudov, Daily Sceptic:

A friend, Ashmedai, highlighted a fascinating animal study, which found that giving pregnant rats the Pfizer Covid vaccine induced ‘autism-like’ traits in the male pups born after such vaccination.

The placebo-controlled study was published in Neurochemical Research.

The researchers set out to evaluate the effects of Covid vaccination on rats during pregnancy to see the effect on the offspring:

This study aimed to investigate the gene expression of WNT, brain-derived neurotrophic factor (BDNF) levels, specific cytokines, m-TOR expression, neuropathology, and autism-related neurobehavioral outcomes in a rat model. Pregnant rats received the COVID-19 mRNA BNT162b2 vaccine during gestation. Subsequent evaluations on male and female offspring included autism-like behaviors, neuronal counts and motor performance.


To their dismay, the scientists indeed found profound disturbances in the neurodevelopment of pups born to rat mothers vaccinated during gestation:

Compared to the control group of rats injected with harmless saline solution, pups born to Covid-vaccinated mothers displayed a decrease in neuronal counts, a marked reduction in social interaction, and abnormal, repetitive patterns of behaviour. The study authors rightly call that autism-like behaviours.

Researchers used well-accepted tests of rat development to evaluate their sociability and novelty tolerance.

It turns out that male pups affected by the Covid vaccine during gestation were abnormally afraid to socialise and actively avoided novel situations. The authors point out that such maladjustments are “autism-like”. They show the comparison with the control group:

Decreased Neuronal Counts and Cognitive Deficiencies of Male Pups

Sadly, Covid-vaccinated male pups had significantly reduced neuronal counts:

The Covid vaccines decreased neuronal counts by one-third:

The above-mentioned CA3 neurons are responsible for spatial intelligence and general cognition, so they are very important for life success in all mammals, including humans.

As a result of cognitive deficiencies due to a lack of neurons, vaccinated male pups failed to learn as well as their unvaccinated control counterparts, suggesting a learning disability:
