Test Before Vaccination

• 

  Laboratory confirmation of a previous dengue infection is required for vaccination with Dengvaxia.

• Testing before vaccination will confirm that your child has had dengue before.
• In children who have not already had dengue, the dengue vaccine increases the risk of hospitalization and severe illness if the child gets dengue after vaccination.
  • Therefore, to reduce the risk of vaccinating children who have never had dengue, a blood test can check for a previous dengue infection.
    • If the test result is positive, your child can be vaccinated.
    • If the test result is negative, your child won’t be able to get vaccinated.
      • Your child should be tested again in one or two years.

Types of testing to confirm a prior dengue infection

• Your child’s healthcare provider will order a blood test to confirm a previous dengue infection. The healthcare provider will order a test that has been approved by the local or territorial health department.

OR

• If your child had a previous dengue illness that was confirmed by a specific type of laboratory test, your child may not need an additional blood test.

Talk to your child’s healthcare provider

• Talk to your child’s healthcare provider to find out if your child is eligible for a dengue vaccine.
