In April 2010, Walvax launched a prefilled syringe dosage form of Haemophilus Influenzae Type b Conjugate Vaccine (Hib). Prefilled syringe vaccine refers to put vaccine liquid into the syringe barrel under sterile conditions, and store in sealed. It only needs simple operation when use.
Haemophilus Influenzae Type b Conjugate Vaccine is a preparation of Haemophilus influenzae type b 58534 strain capsular polysaccharide antigen obtained through fermentation and purification, activation and derivatization covalently bound to tetanus toxoid protein. This vaccine is indicated for infants from the age of 2 months to 5 years to induce active immunization against infectious diseases caused by Haemophilus influenzae type b, such as meningitis, pneumonia, septicemia, cellulitis, arthritis, epiglottitis etc.
Compared to similar products of semi-prefilled syringe dosage form, our prefilled syringe Hib vaccine need just two-step inject operation: Remove the needle shield, and inject. Since no re-dissolution and no need to pierce the vial cap, it can effectively reduce the abundant procedures and waste items in the course of injection. It also can effectively avoid contamination and keep the tip intact. So it can reduce the pain of the vaccinated children. With the accurate dosage, this product can play its full part. All of these make the vaccination more convenient and safer.
