â¢ Peptides are short linear chains of amino acids, whereas proteins are very long chains of amino acids. â¢ Several amino acids are linked together to form a peptide by peptide bonds, while several peptides are linked together to form protein molecules.
Mechanism of Action. Hiberix is a non-infectious vaccine used to prevent Haemophilus influenzae type b (Hib) infection in children. The vaccine works by causing the body to produce its own protection (antibodies) against the disease.
None of the studies included a comparator group that received a booster dose with a US-licensed Haemophilus b Conjugate Vaccine. Studies were conducted in Europe, Canada, and Latin America. Across these studies, the mean age of subjects at the time of booster vaccination with HIBERIX ranged from 16 to 19 months. At the time of vaccination, 172 (17.1%) subjects were 11 to 14 months of age, 642 (63.7%) subjects were 15 to 18 months of age, and 194 (19.2%) subjects were 19 to 25 months of age.
