Secondborn children are often immunized later than firstborns, particularly if an older sibling also experienced delayed immunizations. This study highlights birth order as a factor in timely childhood vaccinations.

Area of Science:

  • Pediatric Health
  • Immunization Practices
  • Public Health

Background:

  • Birth order can influence family dynamics and resource allocation.
  • Understanding factors affecting childhood immunization is crucial for public health.

Purpose of the Study:

  • To investigate the association between birth order and immunization status in children.
  • To determine if secondborn children receive immunizations later than firstborn children.

Main Methods:

  • Retrospective medical record review of immunization dates for 892 children (446 matched sibling pairs).
  • Analysis focused on diphtheria and tetanus toxoids and pertussis vaccine (DTP) and measles-mumps-rubella (MMR) vaccine administration.
  • Compared median ages at immunization and point prevalence of being up-to-date for firstborn vs. secondborn children up to 2 years of age.

Main Results:

  • Secondborn children showed significantly lower rates of full immunization between 5 and 12 months compared to firstborns.
  • Firstborn children were more likely to receive timely DTP2 and DTP3 vaccinations.
  • Secondborn children received DTP2 and DTP3 vaccinations approximately 10 and 20 days later, respectively, than their firstborn siblings.

Conclusions:

  • Secondborn children are at higher risk for delayed immunizations compared to firstborn children.
  • Delayed immunization in a firstborn child increases the risk of delayed immunization in a secondborn sibling.
