For Dengue, as others have said, there is no vax. Here's some mosquito prevention ideas from MD Travel Health:Wear long sleeves, long pants, hats and shoes (rather than sandals). For rural and forested areas, boots are preferable, with pants tucked in, to prevent tick bites. Apply insect repellents containing 20-35% DEET (N,N-diethyl-3-methylbenzamide) or 20% picaridin (Bayrepel) to exposed skin (but not to the eyes, mouth, or open wounds). DEET may also be applied to clothing. Products with a lower concentration of either repellent need to be repplied more frequently. Products with a higher concentration of DEET carry an increased risk of neurologic toxicity, especially in children, without any additional benefit. Do not use either DEET or picaridin on children less than two years of age. For additional protection, apply permethrin-containing compounds to clothing, shoes, and bed nets. Permethrin-treated clothing appears to have little toxicity. Don't sleep with the window open unless there is a screen. If sleeping outdoors or in an accomodation that allows entry of mosquitoes, use a bed net, preferably impregnated with insect repellent, with edges tucked in under the mattress. The mesh size should be less than 1.5 mm. If the sleeping area is not otherwise protected, use a mosquito coil, which fills the room with insecticide through the night. In rural or forested areas, perform a thorough tick check at the end of each day with the assistance of a friend or a full-length mirror. Ticks should be removed with tweezers, grasping the tick by the head. Many tick-borne illnesses can be prevented by prompt tick removal.

As for malaria, again, as other said, no vax. But there are drugs. These include mefloquine (Lariam), atovaquone/proguanil (Malarone), or doxycycline.
Here's a good overview of the possible drugs from MDTravel Health.
Mefloquine (Lariam) has a bad rep for its potential neuropsychological effects. Personally, I would not take it for that reason. There is also a long list of contraindications. You shouldn't take Lariam if you have a history of psychiatric illness (inclulding depression), seizures, or heart conduction problems.
Malarone is a newer drug with much more mild possible adverse effects. Here's a link to the prescribing info: clicky!
Here's some info on Malarone from TravelHealthUK.Com
Doxycycline is an effective anti-malarial drug. The one big problem with it is that it can cause sun sensitivity, resulting in bad sunburns. So if you are in a very sunny spot, this may be a hard drug to take. Here;s the FDA FAQ page on doxy: clicky!
