Vaccination and Health Risks

Your doctor can give you important advice and prescribe vaccines and medications to help you stay safe while traveling abroad. The following are vaccinations and medications you and your physician may wish to consider before travel to Cambodia.

To have the most benefit, see a doctor at least 4-6 weeks before your trip to allow time for your vaccines to take effect. If you are leaving sooner, it is still important to see a doctor as soon as possible for vaccines, medications and information about how to protect yourself from illness and injury while traveling.
Your doctor will make specific recommendations, depending on your health and immunization history, areas of the country you will be visiting, planned activities and other factors. If your travel plans will take you to more than one country during a single trip, be sure to let your health-care provider know. Long-term travelers, such as those who plan to work or study abroad, may also need additional vaccinations as required by their employer or school.
If you have a chronic medical condition, share your travel plans with any doctors who are currently treating you.

Routine		Recommended if you are not up-to-date with routine shots such as, measles/mumps/rubella (MMR) vaccine, diphtheria/pertussis/tetanus (DPT) vaccine, poliovirus vaccine, etc.
