In the previous science page, Gabriela Bucini, Scott C. Merrill, Eric M. Clark, and Julie M. Smith of the Social Ecological Gaming and Simulation Lab at the University of Vermont shared that the decisions made by the players in different scenarios of disease risk, risk communication strategies, and neighboring farm biosecurity implementation allowed us to identify three prominent behavioral groups. The risk tolerant players invested very little in biosecurity in contrast to risk averse players who invested consistently throughout the simulation to protect their farms. Our third category, risk opportunists, primarily invested in biosecurity during high risk scenarios but limited investments during rounds with lower chance of infection.Continue reading “Wait and see?

This short science page offers insights on decision making where a wait-and-see attitude induces a delay in biosecurity investments and implementation, which creates instability and uncertainty in the industry’s ability and capacity to control disease.

Chong Li and colleagues from the University of Minnesota provide new insights for the potential use of the heterologous prime-boost vaccination strategy to control swine infuenza A virus (IAV) infection in pigs by bringing us a research article published in Veterinary Research.
- Heterologous prime-boost vaccination has the potential to deal with diverse IAV infection in multiple animal models.
- Pigs in the heterologous prime-boost vaccination group had more favorable outcomes consistent with a better response against virus challenge (H1N1 and H3N2 IAV) than non-vaccinated pigs.
- Similarly, a multivalent heterologous inactivated vaccine boost to pigs following a single live attenuated IAV vaccine (LAIV) administration was also beneficial.
- More studies are still needed to validate the concept of heterologous prime-boost to control IAV under feld conditions.
