Maximum Age for Infanrix Hexa Administration

Age Limitations for Administration

• The Centers for Disease Control and Prevention recommends that other DTaP-containing combination vaccines like Pediarix are restricted to children aged 6 weeks through 6 years, but are only indicated for the primary 3-dose series, not booster doses 1
• The age restriction is primarily driven by the DTaP component, as the safety of acellular pertussis vaccines in persons aged ≥7 years has not been adequately assessed in the formulations used for infants and young children 2

Important Clinical Context

• If a child reaches age 7 years before completing the vaccination series, they should transition to age-appropriate formulations rather than receiving Infanrix hexa, as recommended by the Centers for Disease Control and Prevention 1, 2

Common Pitfalls to Avoid

• If Infanrix hexa is inadvertently administered beyond the recommended age but before age 7 years, the dose should still be counted as valid if minimum interval requirements have been met, according to the Morbidity and Mortality Weekly Report 3
