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.
The incidence of local adverse events did not increase with subsequent vaccine doses. As HIBERIX was co-administered with either a diphtheria-tetanus-acellular pertussis vaccine or a diphtheria-tetanus-whole cell pertussis vaccine, systemic adverse events cannot be specifically attributed to either vaccine. Most systemic events were mild and resolved spontaneously.
