Three Or More Maternal Doses Of COVID-19 Vaccine Enhance Antibody Concentrations In Preterm Infants Compared To Two Or Fewer Doses, Study Finds

Healio (1/19, Weldon) reported, “Three or more doses of maternal COVID-19 vaccine significantly enhance antibody concentrations in preterm infants compared with two or fewer doses, according to study results published in JAMA Network Open.” According to the research, “cord anti-S antibody geometric mean concentration was 1,000 (95% CI, 874-1,144) after two doses and 9,992 (95% CI, 8381-1,1914) after three or more doses.” MedPage Today (1/19, Kahn) reported, “Notably, cord anti-S antibody levels were similar in preterm and full-term pregnancies, with geometric mean concentrations of 8,818 and 10,423, respectively (P=0.34).”
