Immunisation before travel is not only sensible but also essential
to land in a new country in order to avoid landing in some unavoidable
catastrophe. This can protect against many of the more serious
diseases which may be encountered during travel abroad. It is
advisable to start the Immunisations 3-5 weeks before travel.
It is worth bearing in mind that immunisations do not protect
against many of the more common problems (e.g. travellers'
diarrhoea - infection with enterotoxigenic E.coli, Campylobacter,
Shigella or Salmonella due to poor hygiene) and it is always
wise to ensure high standards of food and water hygiene and
to avoid being bitten by mosquitos and other insects (use
safe, effective insect repellents, mosquito nets, etc.)
The following immunisations are commonly recommended to
travellers:
Polio :
This vaccine is given orally, usually on a lump of sugar,
and is a simple and safe protection against poliomyelitis
which is still prevalent in tropical and developing countries.
A booster is needed every 10 years.
Tetanus And Diphtheria :
