When planning a trip abroad it is necessary to consider
the health risks and take the necessary precautions. Which
vaccines you must take, if any, depend on your destination
and the type of visit you are making.
For instance if you were only visiting hygienic air conditioned
places for only a few days then your visit cannot be compared
to someone visiting rural, poorly developed areas where disease
maybe rife and medical facilities are few and far between.
It is generally accepted that immunisation is only needed
when travelling outside of Northern and Western Europe, North
America, Australia and New Zealand, but some protection,
at least, is recommended.
Presently there are few mandatory immunisation requirements,
apart from yellow fever. When entering many countries, particularly
those in East Africa and South America, you are required
to show a vaccination certificate to verify you have been
immunised. Be careful though because many tour operators
lead people to believe "nothing is necessary" meaning no
certificate is needed for entry to the country and not no
immunisations necessary.
Most vaccines must be taken at least 3 or 4 weeks before
departure but some even longer. Make sure you do not get
caught out and check which vaccines you need way in advance.
