Vaccine

Vaccines work by controlled exposure to harmless whole-pathogens (virus or bacteria) or specific antigens to stimulate the immune system. Based on microbial fermentation systems, Yaohai Bio-Pharma offers a range of vaccine development and manufacturing services, including conventional vaccinations comprised of conjugate, subunit vaccines, live-attenuated, inactivated, and replication-defective pathogens; as well as novel vaccine technology like nucleic acid vaccines (DNA vaccines, mRNA vaccines, and viral vector vaccines), and microbial vector vaccines.
