Article Synopsis
  • Oral rotavirus vaccines show reduced effectiveness in low-income areas where early childhood human cytomegalovirus (HCMV) infections are common, potentially affecting immune responses.
  • A study measured antibodies in vaccinated infants, finding no overall link between HCMV infection status and rotavirus antibody levels; however, HIV-exposed-uninfected infants with HCMV showed significantly lower antibody responses.
  • The findings suggest that while HCMV may not broadly impact rotavirus vaccine responses in all infants, its effects on vulnerable groups like HIV-exposed infants warrant further investigation for improving vaccine effectiveness.
