covid vaccination

This CDC study was used early to claim broad safety of mRNA vaccines in pregnant women in 2021, and as evidence to censor dissent online. It is now notorious for methodological fraud (found in original table 4) which resulted in a large NEJM correction but not a retraction. Lack of promised follow-up, and possible data destruction by this team is under investigation by a US Senator. Initially, this study claimed that miscarriage and stillbirth rate among vaccinated women generally was similar to rate of general population, but used statistical sleight of hand to achieve that result. Upon outcry and correction, the key claims were nullified but the media had already circulated them and never corrected them at scale in the public record.
