Side effects: The DTP vaccine may cause mild side effects such as soreness, redness, or swelling at the injection site, headache, dizziness, feeling sick, mild fever, or tiredness. More serious reactions are rare.
Additional precautions: Travellers should be up to date with routine diphtheria, tetanus, and polio vaccination before travelling. A booster may be recommended depending on your destination and when you last had a tetanus or polio-containing vaccine, especially if travelling to higher-risk areas or places with limited medical care.
Risks caused by diphtheria, tetanus, and polio: These are serious infections that can cause severe illness. Diphtheria can affect the throat and breathing, tetanus can cause painful muscle stiffness and spasms, and polio can affect the nervous system and lead to paralysis.
