There may also be certain medicines that are required for your particular trip where you would find it hard to obtain them from a GP and pulling together a good medical kit if going on a particularly adventurous trip will take some planning.
However, many do have plenty of time and I have lost count of the number of special deliveries, even to airports, that we have had to organise. A few years ago I published a survey of what people considered the most important in preparation after booking a trip; in the 18-30 year old group 50% said looking at what to do when away, 25% thought buying new clothes, 15% mentioned a variety of other things and only 10% thought about having a Travel Health Consultation!
I always recommend that where possible your first travel health consultation is done about eight weeks before travel. Sounds a long time but there are good reasons to consider vaccinations early on:
Having said this it is never too late to come for a consultation and start a course of vaccines as some protection is better than none at all. Being the experts in travel health at Nomad we are used to dealing with all kinds of situations and can supply every conceivable medicine for a travel kit. However to get the best experience, and also have a look at some of our specialist travel supplies, do come early.
