CDC-Malaria in Belize
I'm not aware of any Malaria shot, but there are pills that you can (should) take. My personal opinion is that anyone who will be on the mainland for more than a daytrip should use Malaria prophylaxis.
My kids and I are current on our shots, but I am asking my husband to get poked for Hep A, tetanus and diphtheria. It can't hurt (ok, well maybe a little
) and it just might help.
