We have done the Panama Canal once . Going again this Xmas.
Unless you are going to spend days or weeks in southern Panama
or other countries. No Vaccinations are required.
I would thou suggest the following
1 - Tetanus also known as DPT
2 - Twinrex (Hepititus)
3 - Ducarol (travelers diarrhea)
These should be current for anyone travelling
Check with your Doctors or Travel Clinic.
