I prefer not to use Ft. Dodge, but now have only two to vaccinate, so ordering from Jeffers is no longer an option, as all of the mail-order outfits now 'require' that you pay a sizable fee for second day air with ANY amount of vaccines that cost less than $250 or so total. The area's only reliable vet supply store ONLY carries Ft. Dodge, which IS now owned by Pfizer, so....this year I am trying a 'new-to-me'combo shot...E,W,T, and WN. My horses are stay-at-home, mature. I actually skipped vaccinations altogether last year, but with a wetter summer forecast, I don't wish to 'push my luck',and there HAVE been cases of WN in my state in recent years. I won't bother with flu or rhino unless I decide to take them to an overnight show where they would need to stall or be in a large group of houses in close quarters. I never opted for the 'maximum' multi shots, but am OK with trying out this particular 4-way. I do take them to the vet for Rabies shots.
