What can travelers do to prevent polio?

Get the polio vaccine

Children should be up to date on their routine polio vaccines.

Adult travelers should get an inactivated polio vaccine booster if they:

  • are going to a destination that has circulating poliovirus;
  • have completed their routine polio vaccine series; and
  • have not already received one adult booster dose.

Clinician Information

Ensure that anyone unvaccinated, incompletely vaccinated, or with an unknown polio vaccination status completes the routine polio vaccine series before international travel.
