https://publications.aap.org/pediatrics/article/156/1/e2024070175/202234/Infant-Antibodies-After-Maternal-COVID-19?autologincheck=redirected  Objective:The study aimed to evaluate the kinetics and duration of maternally derived antibodies in infants up to 6 months old, following maternal COVID-19 vaccination during pregnancy or postpartum. Study Design:A prospective multicenter cohort study was conducted across nine U.S. academic sites, enrolling infants born to mothers vaccinated with 2- (n=280) or 3-dose (booster) monovalent mRNA vaccines during pregnancy (n=202) or postpartum (n=36). Primary Outcomes: Antibody Levels: Significantly higher geometric mean titers (GMTs) of binding and neutralizing antibodies (nAb) were observed at birth and 2 months in infants of mothers who received a booster dose during pregnancy compared to those who received 2 doses or were vaccinated postpartum. Sustained Antibody Levels: Higher titers against the vaccine strain persisted up to 6 months in infants of boosted mothers, although not for the Omicron BA.1 and BA.5 variants.    https://pubmed.ncbi.nlm.nih.gov/40478588/   Objective:The study aimed to determine if mailed self-collection kits for CCS, with or without additional patient navigation, could improve screening participation compared to standard telephone reminders. Study Design:This was a pragmatic, parallel, single-blinded, randomized clinical trial conducted within a publicly funded safety-net health system in Houston, Texas. It included 2474 participants who were overdue for CCS. Primary Outcomes: Participation Rates: Among those who received a telephone reminder and mailed self-collection, 41.1% participated in screening, compared to 17.4% who received a telephone reminder alone. When patient navigation was added to mailed self-collection, participation increased to 46.6%. Effectiveness: Self-collection kits significantly improved participation, with a relative participation of 2.36 times higher than telephone reminders alone. Adding patient navigation further modestly increased participation to 2.68 times higher.
