The CDC has important information on getting vaccinated before you travel.

Protect you and your family when traveling in the United States or abroad by:

• Getting the shots required for all countries you and your family plan to visit during your trip
• Making sure you and your family are up-to-date on all routine U.S. vaccines
• Staying informed about travel notices and alerts and how they can affect your family’s travel plans

Vaccinate at least a month before you travel

• Your body needs time to build up immunity.
• You may need several weeks to get all the doses of the vaccine.
• Your primary doctor may not stock travel vaccines. Visit a travel medical clinic.
• You’ll need time to prepare for your pre-travel appointment.
• If the country you visit requires a yellow fever vaccine, only a limited number of clinics have the vaccine and will probably be some distance from where you live. You must get it at least 10 days before travel.
