Pfizers official product labelling information for pregnant women refers only to animal studies, stating No vaccine-related adverse effects on female fertility, fetal development, or postnatal development were reported.
But a freedom of information (FOI) request to the Australian drug regulator in June 2021, shows the study was only carried out in 44 rats (22 injected with 30µg of mRNA vaccine, 22 injected with saline).
The study found the vaccine led to a statistically significant doubling in fetal loss (9.77% mRNA vs 4.09% saline), but Pfizer concluded that the difference between the two groups was not biologically meaningful.
The label also states that Pfizers mRNA vaccine was not tested for its potential to cause carcinogenicity (ability to cause cancer), genotoxicity (ability to damage genetic information), or impairment of male fertility.
Unlike Pfizer, Moderna kept its pregnant rodents alive to test the embryos. Documents accessed by Judicial Watch, showed a statistically significant number of rats were born with skeletal variations after being injected with Modernas mRNA vaccine.
