What Are Warnings and Precautions for Dengue vaccine?


  •  Hypersensitivity
  •  Individuals with severe immunodeficiency or immunosuppression due to disease or therapy

Effects of drug abuse

  • None

Short-Term Effects

  • See “What Are Side Effects Associated with Using Dengue vaccine?”

Long-Term Effects

  • See “What Are Side Effects Associated with Using Dengue vaccine?”


  • May cause hypersensitivity reactions, including anaphylaxis; appropriate medical treatment and supervision must be available following administration
  • Vaccination may not protect all individuals; continue personal protection measures against mosquito bites after vaccination
  • Syncope can occur following or before vaccination as a psychogenic response to injection with a needle; prevent injury from falling and manage syncopal reactions

Uninfected individuals

  • Evaluate individuals for prior dengue infection to avoid vaccinating individuals who have not been previously infected with the dengue virus
  • In unvaccinated individuals, first dengue infections rarely cause severe dengue, while second dengue infections with a different serotype are associated with an increased risk of severe dengue
  • Administration to individuals not previously infected by the dengue virus is associated with an increased risk of severe dengue disease when the vaccinated individual is subsequently infected with any dengue virus serotype
  • There is no FDA-cleared test available to determine previous dengue infection; available non-FDA-cleared tests may yield false-positive results owing to cross-reactivity with other flaviviruses

Drug interaction overview

  • Data unavailable to establish the safety and immunogenicity of coadministration with recommended adolescent vaccines
  • Immunosuppressive therapies, including irradiation, antimetabolites, alkylating agents, cytotoxic drugs, and corticosteroids (greater than physiologic doses), may reduce the immune response to the dengue vaccine
  • A dengue vaccine may cause temporary depression of tuberculin purified-protein derivative (PPD) test sensitivity, leading to false-negative results; perform tuberculin testing before immunization or at least 1-month following

Pregnancy and Lactation

  • Available data on pregnant women are not sufficient to determine the effects of the dengue vaccine on pregnancy, embryo-fetal development, parturition, and postnatal development
  • Pregnancy exposure registry: 1-800-VACCINE (1-800-822-2463)
  • A limited number of inadvertent exposures during pregnancy were reported during clinical studies; isolated adverse pregnancy outcomes (.g, stillbirth, intrauterine death, spontaneous abortion, blighted ovum) observed for these exposed pregnancies, with similar frequency and nature in the vaccinated individuals compared with the control group, and with risk factors identified for all cases

Clinical considerations

  • Pregnant women are at increased risk of complications associated with dengue infection compared with nonpregnant women
  • Pregnant women with dengue may be at increased risk for adverse pregnancy outcomes, including preterm labor and delivery
  • Vertical transmission of dengue virus from mothers with viremia at delivery to their infants reported

Fetal/neonatal adverse effects

  • Vaccine viremia can occur 7-14 days after vaccination with a duration of below 7 days
  • The potential for transmitting the vaccine virus from mother to infant is unknown


  • Human data are not available to assess the dengue vaccine impact on milk production, its presence in breast milk, or its effects on the breastfed child
  • Consider the developmental and health benefits of breastfeeding along with the mother’s clinical need for the vaccine and any potential adverse effects on the breastfed child from the dengue vaccine or the underlying maternal condition
  • Vertical transmission of the dengue virus, including potentially through breastmilk, has been reported
