Hello! This is my first time posting on here(love reading and learning from all of you) so I hope this is in the right spot. My question is this: My father just returned from a third world country and My 11 month old is not vaccinated. Could he carry something back that she could get?? Should there be a certain time frame where he has to wait to see her? I just worry that he could carry something home and since she does not receive vaccinations, that she could get something. It just worries me to death. Please to anyone who has any knowledge on this....please share. Thank you.
