  • Vaccine composition
    Publication number: 20030022304
    Abstract: This invention relates to a general method by which either extemporaneously prepared or liquid Hib/DTPa combination vaccines can be made in order to avoid Hib interference while being able to maintain the maximum, stable adsorption of each antigen onto the aluminium-based adjuvant on which it is most immunogenic. In so doing, pertussis antigens in combination vaccines of the present invention are stably retained in their most potent form.
