Thanks for answering my question! Good to know. They were definitely going to get vaccinated for West Nile, they were given a 5-way in November that included a West Nile vaccine so they are still techincally protected [Right? It's a year?] but I want them on a spring schedule so am doing it again soon. I just wanted to make sure it wasn't all West Nile vaccines, lol.It is just Previnile. Which is one of my favorite vaccines prior to the manufacturing issue of the current batches. The benefit of the vaccine was that it didn't use an adjuvant and did not cause any reactions. Out of the thousands of horses i have vaccinated with previnile, i have not seen a single adverse reaction. I hope they correct the issue because it was an excellent vaccine with a greater than 99% efficacy.
Just a side note riccilove, we led the nation in Washington last year for number of horse cases of west Nile and it's been on the rise the past 3 years in WA, where most other states have seen steady declines. I would make sure your horse is protected as I expect next year to be even worse in WA. with the mild winter we had, and the prevalence of mosquitoes thus far.
