A new publication authored by members of the RID Program local team and national network of collaborators including Dr. Elisabeth McClymont, Dr. Deborah Money, Lucia Forward, Sandra Blitz, and Dr. Isabelle Boucoiran, among many others was just published in JAMA (The Journal of the American Medical Association)! This publication, entitled “The Role of Vaccination in Maternal and Perinatal Outcomes Associated With COVID-19 in Pregnancy” describes the results of the RID Program’s Canadian Surveillance of COVID-19 in Pregnancy: Epidemiology, Maternal and Infant Outcomes Project (CANCOVID-Preg). This project began collecting data on cases of COVID-19 infection in pregnancy identified via Canadian provincial public health databases, from mid-2020 to December 2022. This publication, specifically describes data of cases identified between April 5, 2021 to December 31, 2022 in 9 provinces and territories across Canada, with a total of 26,584 cases identified and 19,899 of these being eligible for analysis. Various data points in regards to maternal and fetal/infant health were collected over the course of the pregnancy and following delivery for each of these cases. This publication aimed to answer the question of the how maternal SARS-CoV-2 vaccination affects maternal and perinatal outcomes following a COVID-19 infection in pregnancy. The main outcomes analyzed for this publication included maternal COVID-19-related hospital admission, maternal COVID-19-related critical care unit admission, and preterm birth. Key findings included that regardless of variant time period (Delta or Omicron), maternal SARS-CoV-2 vaccination prior to and during pregnancy but prior to COVID-19 infection, reduces the risk of maternal COVID-19 related hospital admission, maternal critical care unit admission, and preterm birth!
