    The study analyzed antibody responses to vaccines in 357 children aged 6–36 months, categorizing them into four vaccine responder groups.

  • 2

    Demographic factors and antibiotic exposure were linked to variations in vaccine-induced immunity, with certain groups showing higher antibody levels.

  • 3

    Children not attending daycare and those identified as African American/multiracial had higher vaccine-induced antibody levels compared to White children.

  • 4

    Frequent antibiotic exposure was associated with lower vaccine-induced antibody levels and increased susceptibility to bacterial infections.

    The study highlights the dynamic nature of vaccine responses in children, with potential changes in responder groups over time influenced by various factors.
