Parenteral typhoid vaccine is preferable, as it is a single-shot vaccine. Malaria medication should be brought so that it is available in case of need. Vaccination against rabies should also be considered, especially by persons who will be working in places where medical support is minimal (dog bites can lead to rabies).
There is a high risk to Tick Borne Encephalitis (TBE) in almost all OSCE field operation areas. Travellers should have a TBE vaccination not longer than 3 years before entering the country.
The Institute recommends that all other vaccinations be completed at least three weeks prior to arrival in the area of the field operation.
Field operations do not have supplies of medicines, and in most field operation areas it is very difficult to obtain even rudimentary medical supplies. All field operation members must bring their own prophylactic and other medication.
