diphtheria & tetanus toxoids/ acellular pertussis vaccine/poliovirus vaccine inactivated/hepatitis b vaccine/haemophilus influenzae type b vaccine (Rx)

Not indicated for adults

Primary Immunization

6 weeks to <5 years

• Indicated for active immunization to prevent diphtheria, tetanus, pertussis, poliomyelitis, hepatitis B, and invasive disease due to Haemophilus influenzae type b for use as a 3-dose series in children aged 6 weeks to 4 years (prior to fifth birthday)
• 0.5 mL IM x 3 at 2, 4, 6 months
• First dose may be given as early as age 6 weeks

≥5 years

• Not approved for use

Dosing Considerations

3 doses constitute a primary immunization course against diphtheria, tetanus, H influenzae type b invasive disease, and poliomyelitis

May be used to complete hepatitis B immunization series

3-dose series does not constitute a primary immunization series against pertussis; an additional dose of pertussis-containing vaccine is needed to complete primary series

Pertussis vaccination following Vaxelis

• Children who have received a 3-dose series of Vaxelis should complete primary and pertussis vaccination series (ie, Pentacel, Quadracel, Daptacel) according to respective prescribing information

Vaxelis may be administered in the following patients

• Used to complete first 3 doses of the 5-dose DTaP series in infants and children who have received 1 or 2 doses of Pentacel or Daptacel and are also scheduled to receive the other antigens in Vaxelis
• Infants born to HBsAg-negative mothers, and who have received a dose of any hepatitis B vaccine, prior to or at age 1 month
• Used to complete the hepatitis B vaccination series following 1 or 2 doses of other hepatitis B vaccines, in infants and children born of HBsAg-negative mothers and who are also scheduled to receive the other antigens in Vaxelis
• May be administered to infants and children who have received 1 or 2 doses of H influenzae type b conjugate vaccine and who are also scheduled to receive the other antigens in Vaxelis
• Data are not available on the safety and effectiveness in such infants and children
