Vaccines Based on Non-Recombinant DNA Technology

Vaccines work by controlled exposure to harmless whole-pathogens (viruses or bacteria) or specific antigens, which ensures that the immune system can adequately neutralize the pathogen when the organism is confronted with it.

There have been many technologies applied in vaccine development, including traditional non-recombinant technology (e.g., live attenuated vaccine, inactivated vaccine, polysaccharide vaccine, toxoid vaccine) and recombinant DNA technology (DNA vaccine, mRNA vaccine, recombinant subunit vaccine, VLP vaccine, etc.).

Based on our microbial fermentation systems (BSL-1 and BSL-2 level), Yaohai Bio-Pharma offers Process and Manufacturing Solutions for microbial pathogen-derived vaccines, as follows:
