Ensuring a reliable supply of pure, safe, potent, and effective vaccines is essential for maintaining animal health. The diversity of new pathogens or outbreaks increases the demand for various vaccine types and manufacturing methods. From a manufacturing perspective, many factors are vital for accelerating the production of veterinary vaccines and achieving performance goals, including process scale-up, upstream production, impurity removal, downstream recovery, and quality control, among others. BioVenic offers contract veterinary vaccine manufacturing services to assist you in scaling up your veterinary vaccine samples from the laboratory stage to commercial production.
Veterinary Vaccine Production Platforms
BioVenic has established various of veterinary vaccine development platforms for different types of vaccine development and production. Our platforms enable high-quality manufacturing of different types of vaccine from lab-scale to large-scale to meet your veterinary vaccine research and development requirements.

Description
|
|
Live Attenuated Veterinary Vaccine
|
The infectious potential of attenuated pathogens must be maintained.
|
|
Recombinant Vectored Veterinary Vaccine
|
Using attenuated or harmless microorganisms (e.g., adenoviruses) to transport portions of an antigen to stimulate an immune response.
|
|
Recombinant Protein Subunit Veterinary Vaccine
|
The manufacture of recombinant protein involves the cellular expression in a variety of heterologous expression systems including mammalian cells, baculovirus-insect cells, eukaryotic cells, and prokaryotic cells.
|
|
Conjugate Veterinary Vaccine
|
The covalent attachment of carrier proteins to polysaccharide molecules converts them into T-dependent antigens that efficiently stimulate an immune response.
|
|
Virus-like Particle Veterinary Vaccine
|
VLP can be expressed in a variety of heterologous expression systems, followed by in vivo assembly and then purification from cell lysates, either by recovering partially assembled proteins from cell lysates or assembling them into VLP in vitro.
|
|
DNA Veterinary Vaccine
|
Plasmid DNA is used as the vaccine itself and also as starting material for mRNA vaccines. Its production is plagued by low productivity in microbial fermentation and difficulties in purification.
|
|
mRNA Veterinary Vaccine
|
mRNA can be produced synthetically by in vitro transcription without the removal of cellular or host cell proteins.

Antigen Types
|
Optimization Measures
|
|
Virus
|
High-cell-density systems like bioreactors, achieve high titers through fine-tuning cell substrates, viral parameters, and growth conditions.
|
|
Recombinant Protein
|
Various heterologous expression systems.
During the expression of recombinant proteins, continuous monitoring, optimization of culture media, and culture processes are implemented.
|
|
Plasmid DNA
|
Strictly control the reagents and materials used throughout the production process so that they are free of endotoxin.
The use of Animal-free media ensures the safety of animal research.
|
|
mRNA
|
Using an efficient and economical co-transcription capping technique.
Adjusting the process parameters so that the LNP particle size is as uniform as possible and the mRNA is stably encapsulated in the LNP to form stable nanoparticles.
