Do I need a dengue vaccine before traveling to Nha Trang, and how to protect against mosquitoes?
Based on 2 discussions with 2 participants · Last activity: today
TL;DR
Dengue vaccines QDenga and Dengvaxia are available and recommended, especially for those who already had dengue, though overall infection risk is low outside jungle areas; use DEET repellent (25%+) as a minimum precaution.
What the community said
Bring a strong mosquito/sand flea repellent with at least 25% DEET (good options are sold in Thailand). There was a recent serious dengue case where a tourist had to be emergency-evacuated back to Russia — take precautions seriously.

The actual risk of catching dengue in Nha Trang itself is quite low — the specific mosquito species that carries it isn't the most common, and infection mainly occurs in high-risk zones like jungle areas or dense party districts (similar to Bui Vien in Saigon). Vaccination is still recommended as extra insurance.

Dengue vaccines (QDenga and Dengvaxia) aren't only for people who already had dengue — anyone can get vaccinated, though those with prior infection tolerate it better due to existing antibodies. Both vaccines cover all 4 dengue virus serotypes.
