The autism-like effects were observed in both male and females, but more in the males. From Igor Chudov at igor-chudov.com:
They should have done this experiment before vaccinating humans
A friend of this blog, 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 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, scientists indeed found profound disturbances in the neurodevelopment of pups born to rat mothers vaccinated during gestation:
