Who is dengue vaccination suitable for?
Mainly travellers who previously had dengue or who stay repeatedly or long-term in high-transmission areas. Our practitioner assesses your situation.
What is the schedule?
Two doses three months apart, so start well before departure.
Am I fully protected after vaccination?
No. Daytime mosquito protection remains necessary, because the dengue mosquito bites mostly during the day.
