  • pain (most frequent)
  • tenderness (most frequent)
  • edema
  • pruritus


  • myalgia (most frequent)


Drug-Drug interaction

Concurrent use of immunosuppressives including antineoplastics and corticosteroids may ↓ antibody reponse and ↑ risk of adverse reactions.


Intramuscular (Adults ≥17 yr) 0.5 mL, repeated 28 days later; series completed at least 1 wk prior to potential exposure to JEV.


Suspension for injection (contains protamine): 0.5 mL single dose syringes

Nursing implications

Nursing assessment

  • Determine if patient has had reactions to previous vaccines.
  • Obtain temperature. Vaccine should not be administered to patients with fever >100°F.

Potential Nursing Diagnoses

Risk for infection (Indications)


  • Immunization is administered in 2 doses, 28 days apart, completed at least 1 wk prior to exposure to JEV.
  • Intramuscular: Store in refrigerator; clear liquid with white precipitation may form during storage. Shake syringe well to obtain a white, opaque, homogenous suspension. Do not administer if discolored or contains particulate matter. Inject into deltoid; do not give intravenously, intradermally or subcutaneously.

Patient/Family Teaching

  • Inform patient of the purpose of vaccine and that vaccine is non-infectious. If second dose is missed, contact health care professional to determine when to receive second dose. Maximum protection is not achieved until 1 wk after second dose. Advise patient to read Patient Information Sheet prior to vaccination.
  • Advise patient of precautions to take to reduce exposure to mosquito bites transmitting virus (adequate clothing, use of repellents, mosquito nets). Vaccine may not fully protect everyone who gets the vaccine, does not protect against other types of encephalitis or other diseases transmitted by mosquito bites.
  • Advise patient to tell health care professional what medications they are taking.
  • Advise female patients to notify health care professional if pregnancy is planned or suspected, or if breastfeeding.

Evaluation/Desired Outcomes

  • Protection against Japanese Encephalitis Virus.

Valneva USA, which is based in Gaithersburg, received approval last week for an alternate immunization schedule of Ixiaro, the only vaccine approved in America for protection against the virus, the company announced.
(SeeNews) - Aug 8, 2014 - Biotechnology company Valneva SE (EPA:VLA), a tie-up of Austrian Intercell and French Vivalis, narrowed its first-half net loss by EUR 9.8 million to EUR 12.2 million (USD 16.34m) thanks to higher profitability of the Ixiaro vaccine and merger synergies.
Since 2009, a vaccine of inactivated JE virus derived from Vero cell culture (Ixiaro, manufactured by Intercell Biomedical and distributed by Norvartis) has been available in the United States for adults [greater than or equal to] 17 years who travel during JE virus transmission season to parts of Asia where the virus is endemic.
On June 19, 2013, the Advisory Committee on Immunization Practices (ACIP) voted to extend existing recommendations for use of inactivated Vero cell culture-derived Japanese encephalitis (JE) vaccine (JE-VC) (Ixiaro, Intercell Biomedical) to include children aged 2 months through 16 years (1).
The JE-VC vaccine, manufactured as IXIARO, was licensed for use in adults in the United States, Europe, and Australia in 2009.
However, JEEV / Ixiaro would have the advantage of prior FDA approval making it a more confident choice for travelers from Europe/ America.
