<s>[INST] Is there a vaccination against Dengue? [/INST] There are two live attenuated vaccines available that are licensed in some countries: Dengvaxia and Qdenga. The vaccination is primarily aimed at people who have already been infected with Dengue. They have a high risk of becoming severely ill in case of a new infection due to an excessive immune reaction. The reason for this is that there are four different Dengue virus serotypes. The Ständige Impfkommission (STIKO) has not yet issued a recommendation on Qdenga. Travellers should consult a doctor to clarify if they need to be vaccinated. Immunocompromised people and pregnant women are excluded from vaccination, as with all live vaccines.

Even those who have been vaccinated should continue to protect themselves from mosquitoes, because vaccination reduces the risk of severe courses, but does not necessarily protect against infection.
