Travelers can be considered to be protected four weeks after receiving the initial vaccine dose. A one-time booster dose is recommended for travelers who have previously completed a standard course of polio immunization. Refer to CDC guidelines for vaccinating unimmunized or incompletely immunized persons. Vaccination should be considered for persons staying longer than 3 weeks, adventurous eaters, and those who will venture off the usual tourist routes into small cities, villages and rural areas. Importance of vaccination increases as access to reasonable medical care becomes limited.
Contraindications depend on vaccine type.
