Transcript of "Emergency Vaccination as a Strategy To Control FMD"
Emergency Vaccinationas a Strategy to Controlthe Spread of FMD<br />
Foot-and-mouth disease (FMD) is a highly contagious and economically devastating livestock disease.<br />Historically, the costs of outbreaks – direct, secondary and tertiary – are massive. <br />Outbreaks can lead to strict trade restrictions on the world market, harming the economy.<br />
The most recent U.S. outbreak in 1929 had a devastating effect on agriculture and the economy. Thus, it is imperative to be well prepared.<br />Strategies to control an outbreak may include:<br /> Emergency vaccination.<br /> Large-scale slaughter.<br />
Economists at the FAZD Center used simulation analysis to evaluate the use of emergency vaccination – in addition to slaughter – as strategies for slowing the spread of the FMD virus.<br />
Simulations suggest emergency vaccination will slow outbreaks in California when used in rings of under 10 or 20 kilometers surrounding the outbreak site.<br />The high costs of emergency vaccination are offset in these simulations.<br />
Simulations also show emergency vaccination is effective in the Texas High Plains in rings of less than 5 kilometers.<br />But the high costs are not offset in these simulations.<br />
FAZD Center economists concluded:<br /><ul><li> Emergency vaccination reduces slaughter, but generally is not cost effective.
However, vaccination is a viable option if the goal is to reduce the risk of a catastrophic outcome.</li></li></ul><li>Visit our web site:fazd.tamu.edu<br />
