  • It is permissible to administer 4 doses of hepatitis B vaccine when Pediarix is used following a birth dose of hepatitis B vaccine. However, a dose of Hepatitis B vaccine must be administered on or after 24 weeks of age.
  • Pediarix™ may be given simultaneously with any other vaccine(s) at separate sites.
  • Pediarix™ can be used interchangeably if necessary with single antigen components (DTaP, IPV, Hep B) as long as minimal ages and intervals are observed.
