I'm not aware that you actually "need" any. I never got any when I went. However it may be worth asking your doctor if he recommends any. For info, according to this site http://www.netdoctor.co.uk/travel/caribbean/barbados.shtml Hepatitis A is recommended, and typhoid, diptheria, TB, and Hepatitis A are "sometimes recommended" whatever that means. Great holiday destination by the way. Try to visit Oistins fish fry on a Friday night.
