Even worse, it causes not just ordinary dengue fever, but severe dengue.

A follow-up study five years after the initial trials showed that at least five more out of every 1,000 participants who had been vaccinated went on to develop dengue fever, while an additional two patients developed the more serious severe dengue, when compared to previously uninfected people who did not receive the vaccine.
