I am told that there is no Cholera vaccine to be had in the US for several more weeks.

I travel to BLR by way of DXB next week.

Is there a source in the airport in Dubai? Is it viable to imagine getting a dose in Bangalore upon arrival?

Living in Seattle, I could just about squeeze in a trip to Canada if that was a solution.

    Assuming you're going on a business trip and you take reasonable precautions with food and drink, you are exceedingly unlikely to catch cholera in Bangalore. Commented Jul 29, 2022 at 22:48

    Note that as long as you have access to a moderately well provisioned health care system, Cholera isn't particularly dangerous. The cure is essentially salt water, and the only reason Cholera is still a problem in parts of the world is because parts of the world still don't have easy access to clean water.

The vaccine might not be immediately effective.

For example Superdrug says

You need to finish the course at least one week before travel. This means, that you need to get your first dose at least two weeks before travel.

In Vancouver? Canadian Travel Clinics says

Adults should have two doses of Dukoral and children will need three doses. These doses need to be spaced a week apart. You should aim to complete the entire course at least a week before you arrive at your destination.

  • This is a late comment, but for the benefit of others I'll still chime in. A travel clinic can also prescribe antibiotics, for you to take in case symptoms appear - I received both Dukoral and a just-in-case (i.e. fill it and bring it with you) prescription for azithromycin in advance of travel from my local travel clinic (located in Ontario). The idea is that the Dukoral should work, but if it doesn't and symptoms of cholera / ETEC-induced diarrhea appear, start the antibiotics. Commented Jan 12, 2023 at 17:12
