| Fever can also be caused by teething, dehydration and some childhood immunisations. |
| Typical immunisations for a traveller will include a booster for polio and tetanus, and immunisation against hepatitis A and typhoid. |
| There are immunisations for several of the infections that can cause pneumonia. |
| Most immunisations are given by injection, usually into the muscle or fat of the outer thigh or upper arm. |
| Acute disseminated encephalomyelitis, a rare demyelinating disease, is usually triggered by infections or immunisations. |
| A blood test is then taken one month after the third dose to check that the immunisations have worked. |
