Key result
Simulated CSF vaccination strategies suggest shifting vaccination to 6 weeks and intensifying sow replacement.
Why the study?
Following a classical swine fever outbreak in 2018 after 26 years of absence and the resumption of vaccination in 2019, an effective vaccination strategy for pig populations needed to be determined.
What is the optimal vaccination strategy for classical swine fever in a simulated Japanese pig herd?
What is the optimal vaccination strategy for classical swine fever in a simulated Japanese pig herd?
Simulation modeling suggests that adjusting vaccination timing and implementing intensive sow replacement can optimize herd immunity against classical swine fever in Japanese pig farms.
No takes yet. Share an insight, caveat, or question.
Simulation supports earlier CSF vaccination and sow replacement in models; leaves open field validation before any practice change in Japanese herds.
Ukita et al. (2023) studied Classical swine fever. Classical swine fever vaccination strategies was evaluated on Herd immunity and antibody titer variation. Simulation of CSF vaccination strategies indicated that vaccination age should be shifted earlier from 8 to 6 weeks over time, and intensive sow replacement shortens the period of diverse titers.
