Healio (12/9, VanDewater) reports that a retrospective cohort study “found that pregnant patients who were vaccinated against SARS-CoV-2 were less likely to have severe COVID-19 or any severity of the disease in the context of the delta variant surge.” The findings were published in Obstetrics & Gynecology.

“Pregnancy is an independent risk factor for severe COVID-19; however, it is currently unknown whether pregnant patients with breakthrough infection remain at high risk for severe disease,” John A. Morgan, MD, a fellow in the department of maternal-fetal medicine at Ochsner Clinic Foundation, and colleagues wrote.
