Those diseases have nothing to do with whether you live in a nice area or not.
Meningococcal is spead via saliva, as you know toddlers will put anything in their mouths. 10% of the population carry this bacteria and never even know . It is a standard vaccine in most
canada as well as pneumococcal.
Hep A is spread via fecal oral route and is more common in Hk than US. We had this one extra as a travel vaccine becasue we travel to HK. All it takes is one infected restaurant worker to not wash their hands after going to the bathroom to spread this around. Hong kong also has lots of street food vendors which we eat at, so we felt it was best to protect the whole family.
HK is endemic for hep B, as is most of asia. It is spread via blood. You can get Hep A and B vaccines done together so no extra shots.
Tb, I haven't really looked into this so not sure, for just travelling it is not recommended, but if you are kliving there possibly. Why not just to to a travel vaccine clinic where you live, most major cities should have one.
