in Sub-Saharan Africa and South America, but low in endemic
zones of those two continents. The risk of severe adverse events
among travellers older than 60 years resulting in death after
the vaccination may be higher than the risk of death due to the
disease in some endemic South American countries (Figure 1).
The history of yellow fever and dengue in temperate regions
confirms that transmission of both diseases could recur,
particularly if Ae. aegypti, a more effective vector, were to be
re-introduced.
1970–2002, a total of 10 cases of yellow fever were reported
in unvaccinated travellers from the United States and Europe
who travelled to West Africa (6) or South America (4). 8 of these
10 travellers died. Only one documented case of yellow fever in
a vaccinated traveller occurred, he was from Spain and visited
West Africa 1988.
Before giving the vaccination, a careful risk analysis must
be made. Mandatory vaccinations in endemic and transitional
areas must be respected: e.g. travelling from country to country
in (endemic) countries. No exemptions to please the travellers
should be issued.
