The course involves two doses, which must be at least 3 months apart (for immunological reasons).  A single dose before travel should always protect against DENV-2 (probably for life), whereas the protection against the other serotypes, DENV-1, DENV-3 and DENV-4, is likely to wane with just one dose.  However, if your trip is shorter than 3 months, you could always have the second dose on your return for more balanced, longer term protection.

For those travelling for longer than 3 months, Qdenga is now available in many tropical countries (often at a far lower price), so you could possibly arrange to get the second dose out there.

It is a live vaccine, so not suitable for pregnant or breastfeeding women, or for those who are severely immunocompromised.  If in doubt about this, please contact us to discuss further.

The cost in this country is relatively expensive at £110 per dose, plus the cost of your appointment.
