How long before travel should you have the cholera vaccine?

The number and spacing of doses depend on the vaccine product and the person receiving it. Protection is not assumed immediately after the first dose. A last-minute appointment may still be useful, but a clinician must decide what can be completed safely and what protection can reasonably be expected.

Your destination, type of travel, season, accommodation, and access to safe water all affect the prevention plan. Vaccination is an extra layer of protection; it does not remove the need to avoid unsafe food and drinks.

Book a travel-health appointment as soon as your itinerary is known. Take your vaccine record and list any allergies, pregnancy, breastfeeding, immune problems, or regular medicines. Follow the written instructions for each dose, including any food or drink restrictions that apply to the product you receive.

Pack oral rehydration supplies if advised, learn where medical care is available, and choose treated or sealed water. Eat food that is thoroughly cooked and served hot; avoid raw items that may have been rinsed with unsafe water.

Seek urgent care for profuse watery diarrhoea, vomiting that prevents drinking, severe thirst, dizziness, confusion, marked weakness, or reduced urine. Begin oral rehydration while arranging help when possible. IV fluid therapy may be needed when dehydration is severe. Tell the clinician about recent travel and vaccination.

Ask which product is suitable, how many doses you need, the ideal interval before departure, what to do if travel is soon, and whether your medical history changes the advice.
