We got them: Hep A and Typhoid (we already had Hep B and tetanus).

We're taking Chloroquine (anti malaria tablets 1 per week for 6 weeks) since we are going into the jungle also.

Maybe some would consider it overkill, but I've seen both Hepatitis and Malaria firsthand. Worth a little expense and bother to me (IMO).

The advantage for the shots is you don't need to renew for each trip, they last a while. And believe me, once you've been to AC, you'll have a hankerin' to come back!!
