Data re: COVID-19 Vaccination Before or During Pregnancy

A recent CDC report indicated that risk of stillbirth was 90% greater for pregnant women with COVID-19 when compared to women without COVID-19. This risk was even higher during the period after the Delta variant was introduced.  

Summary of Reported Findings

What is already known about this topic?

Pregnant women are at increased risk for severe disease from COVID-19, and COVID-19 is associated with an increased risk for adverse perinatal outcomes.

What is added by this report?

Among 1,249,634 delivery hospitalizations during March 2020–September 2021, U.S. women with COVID-19 were at increased risk for stillbirth compared with women without COVID-19 (adjusted relative risk [aRR] = 1.90; 95% CI = 1.69–2.15). The magnitude of association was higher during the period of SARS-CoV-2 B.1.617.2 (Delta) variant predominance than during the pre-Delta period.

What are the implications for public health practice?

Implementing evidence-based COVID-19 prevention strategies, including vaccination before or during pregnancy, is critical to reduce the impact of COVID-19 on stillbirths.
