Side effects: The vaccine may cause mild side effects such as headache, tiredness, injection site pain, or low-grade fever.
Additional precautions: Avoid mosquito bites by using insect repellent, wearing long sleeves, and sleeping under mosquito nets—especially during daytime when dengue-carrying mosquitoes are most active.
Risks caused by dengue fever: Dengue can cause high fever, severe headache, joint and muscle pain, and in some cases, serious complications such as bleeding or organ damage. It can be more severe on second infection.
