The tricky part is that the reaction to a vaccine might not show up for a month. This is quite common, as I point out here. And, another strategy would be, if your dog or cat has any sign of illness, any at all (like I describe in my), you can simply say, "My animal from getting more shots. He's not well enough yet. I'm working on his health now, but he's not cured yet."
