The U.S. Food and Drug Administration (FDA) has approved VAXELIS (Diphtheria and Tetanus Toxoids and Acellular Pertussis Adsorbed, Inactivated Poliovirus, Haemophilus b Conjugate [Meningococcal Protein Conjugate] and Hepatitis B [Recombinant] Vaccine) for use in children from 6 weeks through 4 years of age (prior to the 5th birthday). VAXELIS was developed as part of a joint partnership between Sanofi and Merck.
Sanofi and Merck are working to maximize production of VAXELIS to allow for a sustainable supply to meet anticipated U.S. demand. Commercial supply will not be available in the U.S. prior to 2020.
VAXELIS is a vaccine indicated for active immunization to prevent diphtheria, tetanus, pertussis, poliomyelitis, hepatitis B, and invasive disease due to Haemophilus influenzae type b. VAXELIS is approved for use as a 3-dose series in children 6 weeks through 4 years of age (prior to the 5th birthday).
VAXELIS is contraindicated in children with a history of severe allergic reaction (e.g., anaphylaxis) to a previous dose of VAXELIS, any ingredient of VAXELIS, or any other diphtheria toxoid, tetanus toxoid, pertussis-containing vaccine, inactivated poliovirus vaccine, hepatitis B vaccine, or H. influenzae type b vaccine.
Do not administer VAXELIS to anyone with a history of encephalopathy (e.g., coma, decreased level of consciousness, prolonged seizures), within 7 days of a pertussis containing vaccine, that is not attributable to another identifiable cause.
Do not administer VAXELIS to anyone with a history of progressive neurologic disorder until a treatment regimen has been established and the condition has stabilized.
Carefully consider benefits and risks before administering VAXELIS to persons with a history of:
If Guillain-Barré syndrome occurred within 6 weeks of receipt of a prior vaccine containing tetanus toxoid, the risk for Guillain-Barré syndrome may be increased following VAXELIS.
Apnea following intramuscular vaccination has been observed in some infants born prematurely. The decision about when to administer an intramuscular vaccine, including VAXELIS, to an infant born prematurely should be based on considerations of the individual infant’s medical status and the potential benefits and possible risks of vaccination.
Urine antigen detection may not have definitive diagnostic value in suspected H. influenza type b disease following vaccination with VAXELIS.
The solicited adverse reactions following any dose were irritability (≥55%), crying (≥45%), injection site pain (≥44%), somnolence (≥40%), injection site erythema (≥25%), decreased appetite (≥23%), fever ≥38.0°C (≥19%), injection site swelling (≥18%), and vomiting (≥9%).
The 3-dose immunization series consists of a 0.5 mL intramuscular injection, administered at 2, 4, and 6 months of age.
A 3-dose series of VAXELIS does not constitute a primary immunization series against pertussis; an additional dose of pertussis-containing vaccine is needed to complete the primary series.
VAXELIS is the result of the U.S.-based joint-partnership established in 1991 between Merck and Sanofi Pasteur, the vaccines unit of Sanofi, and draws upon both companies' experience in the development, manufacturing and marketing of individual and combination vaccines. VAXELIS includes antigens for diphtheria, tetanus, pertussis (whooping cough), and poliomyelitis from Sanofi and antigens for H. influenzae type b and hepatitis B from Merck.
