A new publication from a team of RID Program collaborators and current team members Dr. Elisabeth McClymont, Dr. Chelsea Elwood and Dr. Deborah Money has been published in Vaccine! This publication, entitled “Maternal-infant transfer of SARS-CoV-2 antibodies following vaccination in pregnancy: A prospective cohort study” describes findings from data collected as part of the COVERED Project’s Immune Sub-Study. The project aimed to understand the impact of receiving SARS-CoV-2 (COVID-19) vaccinations alone and COVID-19 vaccination as well as infection in pregnancy, on the maternal and infant SARS-CoV-2 antibody titers. The data described in this paper were collected through analysis of maternal, umbilical cord and child blood samples as well as breast milk samples, collected at delivery and 4-6 weeks postpartum (no umbilical sample at this instance) for COVID-19 vaccinated pregnancies who delivered at BC Women’s Hospital in Vancouver, BC. Key findings described in the publication include higher antibody concentrations for those with three vaccination doses compared to two doses (if not previously infected with COVID-19), within the three dose population, those that had previously been infected with COVID-19 had higher antibody concentrations than those with no previous infection, and significant correlation between antibody levels in maternal and infant samples which suggests successful transplacental transfer of these antibodies.
