Well, I think a vaccine has nothing to do with what goes out if the digestive system, it isn't like you swallowed the vaccine. It's in the bloodstream and creates antibodies there. But as I said, if you're worried, check with the doctor's office.

Ask your doctor if the laxative would have any effect. I doubt it.
I see your defense about anorexia -- did anyone on here suggest you are anorexic?
