Insights

COVID-19 vaccination during pregnancy showed no increased risk for infant health issues. Infant outcomes like low birthweight and death were within or below prepandemic ranges in a large registry study.

Area of Science:

  • Obstetrics and Gynecology
  • Pediatrics
  • Vaccinology

Background:

  • The COVID-19 Vaccine Pregnancy Registry (C19VPR) tracked pregnant individuals receiving COVID-19 vaccines between December 2020 and June 2021.
  • This study reports on infant health outcomes among participants in the C19VPR.

Purpose of the Study:

  • To assess the incidence of specific infant health outcomes following maternal COVID-19 vaccination.
  • To compare these outcomes against established prepandemic estimates.

Main Methods:

  • Data collected via phone interviews included birthweight (low birthweight [LBW] <2,500g), small-for-gestational-age (SGA), infant death, and 10 prespecified conditions.
  • Follow-up extended from birth to 3 months postpartum, with a subsample followed to 15 months.
  • Incidence rates were compared with historical prepandemic data.

Main Results:

  • Among 19,852 infants with 3-month follow-up, 125 (0.6%) experienced at least one prespecified condition.
  • Incidences of prespecified conditions, LBW, SGA, and death were found to be within or lower than prepandemic ranges.

Conclusions:

  • The incidence of low birthweight, SGA, death, and the 10 investigated infant conditions did not exceed prepandemic estimates in the C19VPR cohort.
  • Findings suggest COVID-19 vaccination during pregnancy is not associated with increased risk for these adverse infant outcomes.

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
