I have a medical question;is it possible/safe/legal to get extra vaccine shots,that arent Required legally by one's own country or for travelling?how would one go about getting them? would the side-effects outweight the positives?
I just want to be sure I wont be killed by some random bug if i ever decide to travel to an exotic location,or more realistically for inmigrants to not-infect me.
So;how do I get all the shots?
