These guys are right, shots are not really needed, but when I went to live there I decided to be safe and get them all. The following is a list from my immunization record over my 3 year stay:

Oral Typhoid (pill)
RHDCV
Hepatitis B
Hepatitis A
Aralen (anti Malaria pill)
Gamma Globulin
Diptheria - Tetanus

Some of these, like the Hepatitus shots, are a sequence of shots over the span of a month. Again, they are not really necessary as health care in the Philippines is very good (in places).
