evidence: A new study from Yale researchers in Obstetrics and Gynecology shows no link between stillbirth and COVID-19 vaccines. Moreover, pregnant women who had received COVID-19 vaccines in pregnancy were at a decreased risk of preterm birth. [...] "The results of this robust case-control study can be used to reassure both pregnant patients and health care professionals that COVID-19 vaccination in pregnancy is not associated with an increased risk of pregnancy loss," said study author Anna Denoble, MD, in a press release. [...] Overall, 38.4% of patients experiencing stillbirth received a COVID-19 vaccine in pregnancy, compared with 39.3% of those with live births.
