Sorry, I am not saying you are wrong, but I don't buy it. This happened the 2nd year Fort Dodge put out the WNV vaccine. I think the vaccine wasn't tested enough and was pushed on the market too soon because horses were dying and owners were yelling for a preventative. Maybe they are better now, but back then? Nope. I don't think they were effective.
If I remember right, the vaccine had very little testing before being put into use.

That is very true Farmpony. I know I was scared out of my mind when WNV hit our area, there was so much in the news about herds of horses dropping dead, people getting sick and dying. You don't hear it very often anymore- I would be curious if there are any statistics that show state by state the new infections each year.

Spent a whole hour today laying in a pasture, waiting for a sparkling vampire to show up. Alas, I woke up and looked over, only to find a mound of horse crap. Sigh.

That is not true. The vaccines get tested extensively before being FDA approved. However, there is nothing like real world use because they just can't perform tests on thousands of horses in a study. They must take a representative sampling and they aren't going to end up with one of every horse with every known medical issue in these studies.

And I am not saying your vet is wrong but showing you where reliable sources have stated that the vaccines are highly effective, including study results.

"Recent literature indicates that all licensed vaccines demonstrate approximately 95% efficacy when horses undergo intrathecal challenge 28 days post-vaccination. These studies support the epidemiological studies that have demonstrated high efficacy for vaccination. Thus vaccination for West Nile virus is recommended as a core vaccine and is an essential standard of care for all horses in North America."--West Nile Virus - AAEP

Incidence and effects of West Nile virus infection in vaccinated and unvaccinated horses in California

Gardner IA, Wong SJ, Ferraro GL, Balasuriya UB, Hullinger PJ, Wilson WD, Shi PY, MacLachlan NJ.
Department of Medicine and Epidemiology, School of Veterinary Medicine, University of California, Davis, CA 95616, USA.

A prospective cohort study was used to estimate the incidence of West Nile virus (WNV) infection in a group of unvaccinated horses (n = 37) in California and compare the effects of natural WNV infection in these unvaccinated horses to a group of co-mingled vaccinated horses (n = 155). Horses initially were vaccinated with either inactivated whole virus (n = 87) or canarypox recombinant (n = 68) WNV vaccines during 2003 or 2004, prior to emergence of WNV in the region. Unvaccinated horses were serologically tested for antibodies to WNV by microsphere immunoassay incorporating recombinant WNV E protein (rE MIA) in December 2003, December 2004, and every two months thereafter until November 2005. Clinical neurologic disease attributable to WNV infection (West Nile disease (WND)) developed in 2 (5.4%) of 37 unvaccinated horses and in 0 of 155 vaccinated horses. One affected horse died. Twenty one (67.7%) of 31 unvaccinated horses that were seronegative to WNV in December, 2004 seroconverted to WNV before the end of the study in November, 2005. Findings from the study indicate that currently-available commercial vaccines are effective in preventing WND and their use is financially justified because clinical disease only occurred in unvaccinated horses and the mean cost of each clinical case of WND was approximately 45 times the cost of a 2-dose WNV vaccination program."--

There are many many studies on safety and efficacy of these vaccines.

Why don't we do this Cindy. Since your vet knows everything, and mine is apparently an idiot who is telling me wrong, why don't you give me your vet's phone number and I will have my vet call your vet and they can educate each other.

Sorry but I am getting a bit irritated here. It is not a question of who is right and who is wrong. Each protocol just like you said, is what is right for the individual horse, situation, and location. Therefore, why argue when someone says what their protocol is?

In just about every medical thread it turns into one person being pushy and saying they are the only right ones. I'm frankly tired of it.

I can find many more links on the internet that show it is NOT effective, or is in some cases, harmful.

Does ANYONE know of a chart or study that shows if the number of new, reported cases has gone up or down in say... the last 5 years?

clap clap applause applause. Thanks draftrider, I agree. We can't seem to even state our thoughts or our vets protocal without being told that obviously our ideas and our vets ideas are wrong and do not follow total studies like a certain persons vet does.
I believe all vets have to pass courses and tests to get their licenses and also do continueing education to keep up to date on everything. Just because my vet or your vet or someone elses vet does it differently than Cindy's vet, it doesn't make it wrong or make us less caring of our animals.
I have not seen a thread with medical discussions that has not become a " nobody can be as smart as my vet or my studies because I am a Vet Tech when she replies. But the problem is not that she replies, but she pretty much tells the OP of each thread that they can't possibly be knowledgable since they are not registered Vet Tech or are not her vet.
Makes one not want to post at all about anything medical.
All vaccinations do not work will all horses, dogs or whatever the animal. A protocal is just that, a protocal. But it isn't cast in stone and each animal is different. Look at the horses that died from the West Nile that was just recalled. New wonder vaccine was made and put out to the public and then after animals died it was recalled. Obviously that study didn't do so good. Some dogs get AIHA from vaccine reactions, some don't. I had a GSD puppy at 5 months old almost die from AIHA and a vaccine, it is very very common, but the vets don't say" don't vaccinate your dog because this reaction can happen. They continue giving the vaccine because studies have shown it won't happen much. Well, trust me, that "Much" that does happen is devastating and expensive and if you are lucky your dog lives.

yea, have seen that and many others. It was a horrible time, she was not allowed away from the house for over 4 months as she had no immune system because she was on such huge doses of Pred. The Pred was used to kill her immune system that was killing her own red blood cells. She did live and is fine. But, like any other thing sometimes what works for one animal does not work for another. She will never receive another vaccination in her lifetime except rabies.
