When traveling to areas with higher risk of diphtheria, tetanus, or polio, it's crucial to ensure your DTP vaccination is up to date. Consider getting the vaccine if:

- You're traveling to countries with limited healthcare infrastructure
- Your last DTP booster was more than 10 years ago
- You're planning adventure activities with increased injury risk
- You'll be in close contact with local populations in endemic areas
- You're travelling for extended periods or to remote locations
- You're visiting areas where polio transmission may still occur

Diphtheria: Sore throat, fever, swollen neck glands, and a thick gray coating in the throat or nose that can cause breathing difficulties and potentially fatal heart and nerve complications.

Tetanus: Muscle stiffness and spasms, particularly in the jaw (lockjaw), difficulty swallowing, fever, and severe muscle contractions that can be life-threatening.

Polio: Fever, headache, vomiting, fatigue, neck stiffness, and pain in the limbs. In severe cases, it can cause paralysis and breathing difficulties.

The DTP vaccine (Revaxis) is given as a single injection into the upper arm muscle. For optimal protection:

- Adults should receive a booster every 10 years
- The vaccine can be given at the same time as other travel vaccines
- Side effects are generally mild, including soreness at the injection site and low-grade fever
- Full protection develops within 2-4 weeks after vaccination
