Pure recombinant and synthetic antigens used in modern vaccines are generally less immunogenic than live/attenuated and inactivated whole organism vaccines. Scientists incorporate immunomodulators or adjuvants with modified delivery vehicles to improve the quality of vaccine production, including nanoparticles, liposomes, micelles and immune stimulating complexes (ISCOMs). Creative Biolabs has experts in formulation development. Our vaccines delivery optimization strategies can provide you with the best advice and accelerate your vaccine development program.
