Dengue Vaccine Du Jour 

Dengue has four distinct ‘serotypes’ (DENV-1, DENV-2, DENV-3, and DENV-4), and protection from any two of them is needed to reduce the chance of serious disease. After a second infection or vaccination followed by a breakthrough infection, people are typically protected against all four.

A paper in Nature suggests that after a dengue infection, the immune system is hyped up enough to protect against a second infection with any serotype for one to two years. So why is a vaccine even necessary?
