Phage-based Veterinary Vaccine Development
Phages are microscopic viruses that have the remarkable ability to infect and eliminate bacteria. Phage-based veterinary vaccines harness these unique viruses to deliver specific pathogen antigens, prompting the immune system to generate a targeted immune response against the pathogen, which offers a high degree of specificity and versatility in veterinary vaccine design. BioVenic specializes in phage-based veterinary vaccine development, granting you access to cutting-edge vaccine technology platforms that hold great promise for advancing animal health.
Phage-based Veterinary Vaccine Development Platforms
Presently, there are two primary categories of phage-based veterinary vaccines well-established in the field, phage display vaccines and phage DNA vaccines. The convergence of these two strategies has given rise to a third approach known as hybrid phage vaccines. BioVenic provides development platforms for these vaccine types, allowing you the flexibility to select the one that aligns best with your specific project needs and preferences.
| Platforms | Description | Advantages | Limitations |
|---|---|---|---|
| Phage Display Veterinary Vaccine | Using phage as a carrier, by integrating exogenous peptide or protein genes into phage genes, they are displayed as fusion proteins on the surface of the phage. |
|
|
| Phage DNA Veterinary Vaccine | Eukaryotic promoter-driven genes encoding protective antigenic peptides or mimetic epitopes are integrated into the phage genome. |
|
|
| Hybrid Phage Veterinary Vaccine | Generated by the combination of phage display and phage DNA vaccine. | / | / |

Adjuvant Development
Some sequences in the phage genome, as vaccine components, can elicit inflammatory signaling by stimulating the TLR pathway in the immune system. This method can trigger a strong antigen-specific immune response. Care must be taken when using such adjuvants to ensure a balance of safety and efficacy. BioVenic provides adjuvant development services to consider combining phage-based veterinary vaccine components with other adjuvants or immunomodulatory substances to balance the immune response and mitigate adverse effects, and to assist you in dose optimization experiments, in an effort to achieve the goal of stimulating the immune response while minimizing the occurrence of adverse effects.
Formulation Development
Phages are structurally stable in the gastrointestinal tract, but phages administered via the oral route may infect intestinal bacteria, possibly leading to ecological disorders. Infection and further replication of phages may induce the release of endotoxins from infected bacteria, increasing the risk of host damage. With our encapsulation and emulsification technologies, phage particles can be precisely encapsulated in polymer or liposome-encapsulated nanoparticles to meet the needs of specific formulations. This precise encapsulation process ensures that the phage is stabilized and maintains its activity. In addition, BioVenic customizes the formulation of phage-based veterinary vaccines based on different forms of administration, including liquid formulations and lyophilization techniques. This means that you can choose the most appropriate form of medicine for your specific situation to ensure effective vaccine delivery and immune response. Whether you need the convenience of a liquid vaccine or the long-term stability of lyophilization technology, BioVenic offers tailor-made solutions.
In Vivo and In Vitro Assessments
BioVenic offers comprehensive phage vaccine assessment services covering all aspects of in vivo and in vitro to ensure that your vaccine program can move forward successfully. BioVenic provides animal modeling services to evaluate the immunogenicity, safety and efficacy of phage-based veterinary vaccines. This includes experiments in different animal models such as mice, rats, and rabbits. We also provide in vitro immunology tests to evaluate the cellular and humoral immune response of vaccines to ensure that your vaccine is indeed highly immunogenic, and stability tests to ensure that vaccines remain active under different storage conditions for your subsequent use.
