Last updated

For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.

Summary

Available Japanese encephalitis vaccines are generally inactivated, so the main concern is a weaker immune response in a patient on everolimus. This matters for travelers to endemic areas who may be left under-protected.

What this interaction means in plain words

Everolimus and Japanese encephalitis virus vaccine can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Evidence level: Low

Why it happens

mTOR inhibition reduces lymphocyte proliferation and vaccine-induced immune response.

What to do

Vaccinate well before travel and ideally before everolimus is started. Consider checking antibody response and reinforce mosquito-avoidance measures.

What to ask your pharmacist

  • Should I take them at different times of day?
  • Does the dose of either medicine need to change?
  • Is there anything I should avoid, such as alcohol or certain foods, while on both?
