Does anyone know the difference between the West Nile Innovator and the West Nile Innovator DNA vaccine?
Yep- Vaccines are made in one of a few ways. The basic idea is to stimulate the immune system to make antibodies (which fight off bacteria and viruses) against a pathogen ("germ"). The two most common techniques are to take a virus and kill it and then inject it into the animal or human or to modify the virus in such a way that it is still "live" but cannot induce disease.

More recently DNA vaccines have been developed (there are very few available but we will be seeing more and more in the near future) by which the specific part of the virus that the body needs to react to is genetically copied, inserted into a harmless virus and then injected into the animal. This way there is no chance of creating the disease as there sometimes is with the other two methods (though no technique is fool proof).

TMI?? ha! this is a very simplified version but the bottom line is that Fort Dodge wanted to jump on the bandwagon because DNA vaccines are the "sexy new thing" and they didn't want to be left behind. As far as safety and efficacy there has been NO difference shown between the two in studies so I'd go with what is available and cheap. Good luck!
