The unvaccinated"/not infected" group became pregnant 57% of the time, while the vaccinated group only became pregnant 23% of the time.

A new study published Tuesday in Clinical and Experimental Medicine analyzed the effect of Pfizer Inc.'s mRNA COVID-19 jab on in vitro fertilization (IVF) treatment outcomes.

IVF is a fertility treatment wherein eggs are fertilized with sperm outside the body, and the resulting embryos are then transferred to the uterus to potentially lead to pregnancy.

It's worth noting that Pfizer's safety data—only made available by order of a Texas federal judge—show the company and the U.S. Food & Drug Administration (FDA) were aware that the shot was linked to numerous negative pregnancy-related outcomes before making it available to the public.
