What Is the Dengue Virus?
6. Can Dengue Be Prevented?
There is a vaccine for dengue fever, but it is currently only recommended for people who have already been infected once. People who get the vaccine and have not had dengue before have an increased chance of developing severe dengue if they get sick anyway. While the vaccine may reduce the likelihood of getting dengue a second time, it is not 100% effective.
The only completely effective method to avoid getting dengue for the first time is to avoid areas where Aedes mosquitoes are found. If you are going to be in one of these places, you can take measures to avoid mosquito bites.
