[RC] EHV virus in Wellington - k s swigart

Anyway, I'm just glad my guys aren't communing with
others right now.  And that they are vaccinated.

From:

"...For example, in the case of EHV-1 infection at the University riding
school in Findlay, OH, more than 90% of the 138 horses became clinically
sick, 35% developed neurological disease and 9% (12 horses) died or had
to be euthanized. Another striking feature is that recent neurological
cases of EHV-1 infection occurred despite regular vaccinations in very
short intervals, indicating the possibility of the circulation of EHV-1
variants that are able to break vaccine protection. Alternatively, as
suggested primarily by the outbreak at the University of Findlay,
extensive use of inactivated vaccines may result in significantly
increased susceptibility to the neurological form of the disease upon
exposure to the agent."

Not communig with others is a good way of avoiding the disease (since it
is transmitted directly from horse to horse), but I don't know that I
would count on having vaccinated my horse for Rhino to protect it from
getting the deadly form of the disease.

The jury is still out on whether it works for that at all, or if it may
even make it more likely that having been regularly vaccinated your
horse will get the neurological form of the disease.
