Vaccination and pregnancy

In clinical trials, an adverse event is anything negative that happens during the study period that may or may not have anything to do with the vaccine. Adverse events from maternal exposure include anything negative that occurred before, during, or after pregnancy, regardless of whether the vaccine was involved at all.

Estimates show that up to 30% of pregnancies end in miscarriage, including some before the pregnancy was known. The number of miscarriages during Pfizer’s clinical trials was well within that threshold. The same holds true for all pregnancy-related adverse events in the study.

Dr. Wolf also lists a number of adverse events occurring in babies exposed to breastmilk of those vaccinated while breastfeeding. Among the vomiting, lethargy, and myriad other adverse events, she also mentioned roseola, a contagious viral illness. Neither the COVID vaccine nor trace amounts of mRNA in breastmilk can cause this viral illness. Only a virus can do that.

The point of collecting adverse event data during trials or through databases such as VAERS is to compare the number of events that happen to those who have been vaccinated and the number of these events that occur in the general population or those not involved in the clinical trials. These systems have shown the COVID vaccine to be safe during pregnancy and breastfeeding.

Getting COVID during pregnancy is risky. Being infected while pregnant makes you 4 times more likely to be admitted to an intensive care unit, 15 times more likely to be ventilated, and 7 times more likely to die compared to people who didn’t get COVID during pregnancy.
