As a human I do not need to go to the doctors every year and get my boosters so why do animals...is this just a money making scheme by the drugs companies and /or vets? Do the diseases these vaccines protect against mutate quickly more like the human flu?
It's happened a couple of times now that directly after I have a vaccination (the most recent was the rabies vaccine) that I get a slightly acrid taste in my mouth. What causes this?
