I'm pro-immunizations but did not do the Hep B or chicken pox vaccine on my 4 year old.
Sexually transmitted diseases are rampant in the US, which is probably why the Hep B is now given to newborns. And as L&D nurses, we see lots of stuff that would make your head spin . . .
However, knowing that I'm not risking my newborn, I opted out of Hep B.
We did have to immunize our daughter before she headed to high school against Hep B and I did go along with that. As an adult I also have the vaccine. I see no problem with that.
But a baby? Unless there is a known risk? I'd rather focus on the real risks - polio, measles, mumps, rubella, etc.
