Japanese Encephalitis Vaccine

The licensed schedule is two injections delivered 28 days apart. Immunity develops seven days after the second dose, so aim to finish at least a week before you reach a risk area. An accelerated course may be possible for adults when time is short.

You should delay vaccination if you have a fever on appointment day. Tell our pharmacist about severe allergies to vaccine ingredients or if you reacted badly to another vaccine in the past. Pregnant individuals are assessed carefully; benefits usually outweigh theoretical risks when travel is unavoidable.

Most people notice only mild soreness at the injection site. Occasional headaches or low‑grade fever settle within 24 hours. Severe allergic reactions are very rare. We monitor you for 10 minutes after each dose and provide a 24‑hour helpline.

Current guidance states immunity lasts at least 12 months. A booster after one year may be advised for ongoing travel or occupational exposure. Our recall system reminds you when follow‑up is due.

IXIARO is licensed from age two months but national advisers recommend selective use from two years unless risk is high. Our pharmacist will balance travel plans, mosquito exposure, and your child’s health to help you decide.

Wear loose long‑sleeved clothing after dusk. Apply insect repellent containing 50 percent DEET. Sleep under a permethrin treated net if accommodation is unscreened. These measures add an extra barrier and protect you against other mosquito diseases too.
