Understanding Polio: Health Impacts and Risks

Polio is a viral infection that can cause paralysis and even death. While it has been largely eradicated in many parts of the world, it remains a risk in areas with low vaccination coverage. The virus spreads through contaminated food and water, like hepatitis A, and can affect both children and adults.

Polio in the World: What You Need to Know

Despite global vaccination efforts, polio remains a risk in some parts of the world. We have been trying for decades to eradicate polio from the planet, but the disease persists in regions with low vaccination rates, including parts of Africa and Asia.

Specific vaccination recommendations vary from country to country, so it’s best to check with your travel health specialist if you are visiting these countries.

Polio Vaccine Overview: Benefits and Availability

There are two types of polio vaccines: inactivated (IPV) and live oral (OPV). IPV is the only vaccine used in the U.S. and many other countries, providing strong protection against all three types of poliovirus. OPV is still used in some countries due to its ease of administration and ability to provide community-level protection.

Eligibility Criteria for Polio Vaccination

All children receive 4 doses of polio vaccine as part of their routine childhood immunization series. Adults who did not complete the full polio vaccination series as children, or those traveling to high-risk areas, should receive the polio vaccine. Your healthcare provider can help determine if you need a booster or additional doses.

Travel Requirements for Polio Vaccination

In some cases, proof of polio vaccination may be required for entry into certain countries, particularly those experiencing outbreaks. This is part of international health regulations aimed at preventing the spread of the virus. Your travel health specialist can tell you if these countries are included on your itinerary.

Longevity of Immunity with Polio Vaccine

For most people, if you had your polio vaccinations as a child, a single booster dose provides lifelong protection. However, those who did not complete the initial series will likely need additional doses. Discuss your vaccination history with your provider before traveling.

Finding a Polio Vaccination 

TravelBug Health always carries the polio vaccine. Your child’s pediatrician may also have it, since it is part of the routine childhood immunization schedule. During your pre-travel consultation, ask your provider what the recommendations for polio vaccination are for the countries you will visit.
