There is no vaccine against WEE for humans, although there is a vaccine for horses. Prevention of WEE focuses on controlling mosquitoes and avoiding mosquito bites. Steps you can take to avoid mosquito bites include:
- Stay inside between dusk and dark, when mosquitoes are most active.
- Wear long pants and long-sleeved shirts when outside.
- Spray exposed skin with an insect repellent that contains up to 35% diethyltoluamide (DEET).
