Association of Maternal SARS-CoV-2 Infection in Pregnancy With Neonatal Outcomes
SARS-CoV-2 infection in pregnancy (from conception to 1 week after birth) was significantly associated with a 1.4-fold higher risk of any neonatal respiratory disorder after matching for maternal characteristics in a nationwide cohort study in Sweden (n=88,159 infants). Admission for neonatal care, respiratory distress syndrome, and hyperbilirubinemia were also associated with maternal SARS-CoV-2 test positivity….
Maternal Antibody Response, Neutralizing Potency, and Placental Antibody Transfer After Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) Infection
Among maternal blood samples from SARS-CoV-2 positive patients obtained after delivery (n=32), higher median anti-RBD IgG titers were significantly associated with symptomatic (vs. asymptomatic) infection but not with having a PCR-positive test more than 14 days earlier (vs. PCR-positive test within 14 days). Paired cord blood samples also obtained after delivery show that median cord/maternal…

COVID-19 Vaccine Response in Pregnant and Lactating Women a Cohort Study
[Pre-print, not peer-reviewed] The Pfizer-BioNTech and Moderna vaccines elicited similar immune responses among pregnant (n=84) and lactating (n=31) women compared to non-pregnant reproductive-age women (n=16). All vaccine-induced SARS-CoV-2-specific antibody titers were higher compared to titers from a group of pregnant women (n=37) that had SARS-CoV-2 infection 4-12 weeks prior. Vaccine-induced antibodies were detected in all…

Singleton Preterm Birth Rates for Racial and Ethnic Groups during the Coronavirus Disease 2019 Pandemic in California

During a 4-month period following the state-wide COVID-19 lockdown in California in March, 2020, there was…
