Hepatitis A vaccine does require a booster after 6 months, and a second booster dose 20 years later if you're still at risk.
There are also vaccines combining hepatitis A and B , or hepatitis A and typhoid.
The risk of hepatitis B in the Philippines is low. ( Up to 1/10 of the population are carriers of hep B, however. At risk include healthcare workers, those having unprotected sex with strangers, needle sharing, or those requiring medical / dental treatment).
Usually a total of 5 doses of tetanus vaccine (probably received from school age onwards) is sufficient for long term protection.
Typhoid vaccination is recommended, especially if there's a chance of poor standards of food and water hygiene, or staying long-term.
A diphtheria-containing vaccine may be considered 10 years after the last dose. BCG for tuberculosis, rabies, and Japanese encephalitis vaccines are not normally recommended.
There is no polio or yellow fever in the Philippines.
There are no vaccines for malaria or dengue fever.
