Transplacental Transmission of the COVID-19 Vaccine mRNA: Evidence from Placental, Maternal and Cord Blood Analyses Post-Vaccination; American Journal of Obstetrics and Gynecology, Jan. 24, 2024 (journal pre-proof).

COVID-19 immunization products (“vaccines”) were supposed to stay at the injection site. However, according to a New York University study, vaccine messenger RNA (mRNA) and coronavirus spike protein can reach placentas and umbilical cords in pregnant women.

This study involved just two patients. Patient 1, a 34-year-old pregnant woman, received a Pfizer two-shot primary round and two boosters (one Pfizer, one Moderna), with the last dose administered two days before delivering by cesarean section. Investigators collected samples of her placenta, blood and cord blood post-delivery.

Patient 2 was 33 and received two Pfizer doses, the last 10 days before her vaginal delivery. Only placental samples were available from this patient.

Vaccine mRNA was detected in both placentas. Spike protein was found in the placenta of Patient 2 but not Patient 1. mRNA from the vaccine was found in the cord and maternal blood of Patient 1.

The authors concluded: “These two cases demonstrate, for the first time, the ability of the COVID-19 vaccine mRNA to penetrate the fetal-placental barrier and reach the intrauterine environment.”
