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 recombinant DNA technology (DNA vaccine, mRNA vaccine, recombinant subunit vaccine, VLP vaccine, etc.) and traditional non-recombinant technology (e.g., live attenuated vaccine, inactivated vaccine, polysaccharide vaccine, toxoid vaccine).
Based on our microbial expression systems (Escherichia coli, yeast), Yaohai Bio-Pharma offers Process and Manufacturing Solutions for recombinant vaccines against viruses, bacteria, cancer/tumors, and other diseases:
