The vaccines you need for Vietnam depend on your route, the length of your trip and how you travel. Several vaccines are recommended for your health. We’ll confirm current entry requirements at your consultation.
Street food is a highlight, so choose busy stalls and freshly cooked dishes. Dengue occurs in cities and countryside alike. Trekking in the northern highlands, cycling in rural areas or riding a motorbike each bring extra risks to discuss at your consultation. The north can be cool in winter while the south stays hot, so the season matters too.
TMB clinician insight
“Many of the Irish travellers we see for Vietnam are doing the whole country in three weeks, from Hanoi and Ha Long Bay down to Hoi An and Ho Chi Minh City. At that pace, one stomach bug can cost you a leg of the trip. I suggest packing a simple kit with oral rehydration salts, and asking us what else to bring.“
Dr Graham Fry, Chief Medical Director, TMB
