<s>[INST] How is the dengue vaccine administered? [/INST] The dengue vaccine is injected in the arm muscle. A total of three doses are given six months apart for full protection. Clinical studies indicate that the dengue vaccine can protect children against dengue for at least six years.

Before kids can get the dengue vaccine, a laboratory test is required to confirm that they have previously had a dengue infection.

The blood test will check to see if your child has had a previous dengue infection.

If the lab test results are positive, they can receive the dengue vaccine.

If the lab test results are negative, they won't be able to be vaccinated. Your child or teen should be tested again in one or two years. Source: HEALTHY CHILDREN.ORG.
