I don't think it makes sense for most things. Rabies has a slow enough incubation that if you get vaccinated within a couple of days your immune system can win the race.

I was thinking more of things like the hepatitis B vaccine or anything that isn't common in your area. It makes more sense to me to follow the same logic people use when traveling: get vaccinated for dangerous illnesses shortly before going somewhere that might expose you to the disease.

Childhood Vaccine Schedule Thoughts and Questions

Thanks for posting this.

I have a question regarding this part:

> There's also an issue of why we're vaccinating really young kids for diseases long before they have any appreciable risk of exposure. I didn't get a rabies vaccine when I was a newborn, for instance (that waited until after a dog bit me in the Caribbean). Shouldn't timing be somewhat related to likelihood of exposure?

What is the rationale for getting a vaccine _after_ exposure? Someone please explain it to me.
