I think all should take a look at their vaccinations. I am pretty up to date with all my jabs and boosters, but have been advised to have Hep B, and in order to travel to Medalin, we need a Yellow Fever jab. (Apparently). Rabies is also reccommended. Hep B and Rabies (if you decide to have it) are a course of three, first on day 0, second on day 7 and third on day 28. And so in order to fit them in before travel, you need to start having them started now.
Not wanting to panic anyone, as I am sure you are all up to date. Just want to make peoeple aware it may be worth a visit to your GP to clarify.
