Whilst amateur medical advice is helpful
[QUOTE=Duniawala;1404358]For those who want to know. If you are born and bred in the West, US, Canada and 1st world countries it is best to get the recommended vaccinations as you have never been exposed to the germs of SE Asia. However, Hepatitis is always recommended for all.[/QUOTE]Unless you area qualified medical doctor with expertise in tropical medicine I suggest you do what all the sensible people do . Go see a doctor with experience in tropical medicine. At least their advice is backed by proper technical input.
What is more your advice is not based on medical fact. Irrespective of where you are born you do not have immunity from "the germs of SE Asia" for which inoculations are required / recommended.
You need to learn to differentiate
[QUOTE=Duniawala;1404737]Yes, it is based on a medical fact. Go research it. US is so sanitized that the people from there are very susceptible to the diseases of an new place. What do you think happened to the native folks when the Europeans colonized the Americas.[/QUOTE]Between problems caused by lack of immunity to local germs which cause D and V and diseases that all get irrespective of where they live / come from- eg hepatitis. Malaria.
Your example is irrelevant and has nothing to the with locally built up bacterial disease resistance.
But then you are not a doctor and any non-medic who states 'facts' is usually relying on Wikapedia, which is usually written by the ignorant for the less ignorant.
