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.
