Travellers to foreign countries in particular tropical regions will need to be vaccinated against an aray of illnesses and diseases. Individual should obtain information relating to the country or countries they intend to visit, when deciding which travel vaccines they require.

Travellers should also consider the nature of their trip; e.g. whether you are a staying at or visiting only hygienic, air conditioned premises for a few days which would pose less of a risk of infection to someone travelling extensively to rural areas where health risks are considerably higher and medical facilities are limited.
