Overview of Vaccine

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

Conventional vaccinations comprise conjugate and subunit vaccines, as well as live-attenuated, inactivated, and replication-defective pathogens. They may contain live-attenuated organisms; inactivated organisms; inactivated toxins; antigens or antigenic epitopes, like subunit and conjugate vaccines.

Limitations of traditional technologies have triggered the application of novel vaccine approaches, including nucleic acid vaccines, like DNA vaccines and mRNA vaccines, viral vector vaccines, as well as microbial vector vaccines encoding the target antigens or antigenic epitopes.

Yaohai Bio-Pharma offers a range of vaccine services using microbial fermentation systems, as follows:
