[QUOTE=SirTeddykins;4560480]Thank you. I hope the OP finds the site useful. As with everything, I do not believe that a one size fits all approach is the best approach to anything. I think everyone is correct in stating the known pros AND cons of this vaccine and I think it is the right thing to consider both and then imperative to follow those considerations up with individualized vet advice.


For example, my vets advice was on the basis that I live in England. He confirmed that the chance of contracting Lepto was 1:10,000,000 (due to the vaccinations efficacy in minimizing contraction) and the chance of reaction to the vaccine was 1:10,000,000,000. Based on these odds, he felt it was a good idea to get the vaccination because the disease (if contracted) is very serious. It is up to the individuals thoughts, environment, risk ratio calculation etc to decide on what they think is the best course of action but I firmly believe that vets have the most up to date info re: vaccinations. For example, my vet stated that adverse reactions used to be very common until a few years back when the live antibodies were reduced or altered and reflected in a vaccination brand change. However, this was info from last year and I would not personally be up to date on any gains made in this area as of today QUOTE]



I admittedly know nothing about this topic (which is why I read these threads). I assume the 1 in 10 million chance of contracting Lepto is for the dogs who have been vaccinated. But only a 1 in 10 billion chance of having a reaction. Those odds are astronomical. Why is there even a concern about it?
