Thesitcomgirls, you don't want the Lyme vaccine. I was part of the vaccine development program. The vaccine was worse and gave more side effects than when I had Lyme disease. One of the things that I wish I had never participated in.
I no longer immunize against lepto because of adverse reactions and the fact that the incidence of the disease is so minimal. I immunize pups, booster at 9 months and 18 months, and that is the end of their vaccination, except for rabies vacc. Gambling? Maybe, but I have kept my dogs healthy...
