Hello George, with regards to vaccinations and tablets, the best advice I can give you is to consult your GP before your trip. Your GP is instrumental in deciding what medication is required, if any. They will look at individuals, consider where they will be travelling, and then recommend any vaccinations or tablets for the individual, if required. I do not feel comfortable making those kinds of recommendations myself.
To give you an idea of what you might need, you could take a quick look at this website:

I hope my input has been helpful, and if you have any other queries then feel free to message me.
Kind regards
