- myalgia (most frequent)
Drug-Drug interactionConcurrent use of immunosuppressives including antineoplastics and corticosteroids may ↓ antibody reponse and ↑ risk of adverse reactions.

Potential Nursing DiagnosesRisk 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.
- 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.
