Hi Johannes, yes we can assist and make a few comments about a common question. All travellers should consider their health before travel and vaccines are one aspect of that. Most vaccines are for our general protection, so we have to consider our general routine vaccines first, then consider any travel-specific ones. With travel-related vaccines, there are common ones like hepatitis-A and typhoid that are common for most travellers, and some less common ones like rabies which might be relevant depending on activities, location, duration of travel etc. Yellow fever vaccination may be an actual requirement for some itineraries, particularly for those in and out of South American countries like you.
So, what vaccines are recommended for you personally depends on what you have had in the past, whether you are up-to-date with your routine vcaiines, and the exact detail of your travels. While all that sounds complicated, and you probably won't need much, a consultation is required with an expert Dr to get it right for you. See you soon. Dr TonyClose X
