Autogenous vaccines: determining product need and antigen selection, production and testing considerations

Area of Science:

• Veterinary immunology
• Swine health management
• Vaccine regulation

Background:

• Significant sales of swine autogenous vaccines in the US, totaling $16.06 million.
• Swine influenza and Porcine Reproductive and Respiratory Syndrome (PRRS) vaccines constitute over half of autogenous vaccine sales.
• Observed usage patterns indicate potential violations of United States Department of Agriculture (USDA) regulations for autogenous vaccine production and use.

Purpose of the Study:

• To propose criteria for the use and selection of swine autogenous vaccines.
• To minimize the potential for abuse of existing autogenous vaccine regulations.
• To address concerns regarding vaccine efficacy, food safety, and regulatory compliance.

Main Methods:

• Analysis of usage patterns and sales data for swine autogenous vaccines.
• Development of a decision tree to guide product selection and use.
• Consideration of factors including registered product availability, strain variation, and vaccine technology.

Main Results:

• Identification of potential regulatory violations in the current use of swine autogenous vaccines.
• A proposed framework incorporating decision trees and specific criteria for autogenous vaccine application.
• Scenarios for testing and production that balance speed with food safety considerations.

Conclusions:

• Current practices surrounding swine autogenous vaccines may not fully comply with USDA regulations.
• Implementation of proposed selection criteria and decision trees can help mitigate regulatory abuse.
• The proposed framework supports the rapid production of autogenous vaccines while maintaining food safety standards.
