MONDAY, Oct. 2, 2023 (HealthDay News) — Maternal COVID-19 vaccination provides some protection against COVID-19-related hospitalization among infants, especially those aged younger than 3 months, according to research published in the Sept. 29 issue of the U.S. Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report<\/em>.<\/p>\n Regina M. Simeone, Ph.D., from the CDC in Atlanta, and colleagues conducted a case-control study to examine the effectiveness of maternal receipt of a COVID-19 vaccine dose during pregnancy against COVID-19-related hospitalization among infants aged younger than 6 months and a subset aged younger than 3 months. Vaccine effectiveness (VE) was compared for case patients (infants hospitalized for COVID-19 with a positive severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2] test result) and control patients (infants hospitalized for COVID-19-like illness with a negative SARS-CoV-2 result). The odds of receipt of maternal COVID-19 vaccine dose during pregnancy were compared to maternal nonvaccination between case and control patients.<\/p>\n The researchers found that the VE of maternal vaccination during pregnancy was 35 and 54 percent against COVID-19-related hospitalization among infants aged younger than 6 months and younger than 3 months, respectively. Intensive care unit admissions occurred in 23 percent of case patients; invasive mechanical ventilation was more common for infants of unvaccinated versus vaccinated mothers (9 versus 1 percent).<\/p>\n “Expectant mothers should be counseled to remain current with COVID-19 vaccination to protect themselves and their infants from hospitalization and severe outcomes associated with COVID-19,” the authors write.<\/strong><\/p>\n Several authors disclosed ties to the biopharmaceutical industry.<\/p>\n
