Case Reports
Serious adverse events associated with yellow fever 17DD vaccine in Brazil: a report of two cases.
The yellow fever vaccine is regarded as one of the safest attenuated virus vaccines, with few side-effects or adverse events.

Host factors, probably idiosyncratic reactions, might have had a substantial contributed to the unexpected outcome.
