What you need to know about the dengue vaccine:

A vaccine to protect against a dengue virus infection is not generally recommended currently. The vaccine is only recommended for children 9 through 16 years old who live in an area where dengue is common. A past dengue virus infection must be confirmed before the vaccine will be given. The vaccine is given as a shot in 3 doses, each 6 months apart. It can be given with other vaccines.

How a dengue virus is spread:

A dengue virus is most commonly spread to a human through the bite of an infected mosquito. Mosquitoes are usually found near water. Examples include ponds, buckets of water, animal dishes, and flower pots. The number of infected mosquitos may increase during rainy or humid seasons. A dengue virus may be passed from a mother to her unborn baby.
