As for Hep B: A lot of people are symptomless carriers. It's a problem in Asian-Americans (Hep B is endemic in some Asian countries, particularly China). The SF Health Department has run campaigns encouraging Hep B vaccination in the Asian community because of familial transmission.
I had a flu shot at 36 weeks. Baby won't be able to get one (flu shots may not even be effective in under-2s, I've seen conflicting advice). Baby may get some protection from me this way. I have a preschooler, so she just brings every germ home.
