1) My wife has heard from several doctors/friends in her area that getting all her vaccinations at once can be bad for her immune system. Does anyone know if this is true?
(I've asked this to 2 doctors, one when I was Indonesia and the other one when I had to do the medical examination for K3 visa in Switzerland, and both said it's true. That's why they were very cautious in giving me the needed vaccination. Thank goodness, I didn't have to get a lot of vaccinnations. )
2) Also, she may have trouble getting her records of previous vaccinations. Are there any vaccinations that would be harmful to get again even if she already had them some time in the past?
(According to my doctor, it's not harmful to get another same vaccination, but it's just a waste of time and money. Why do you need to get same vaccinnes when your body has developed an antibody to a certain disease, right?)
3) If several different clinics have records of different vaccinations, is this ok? Or do they all need to be from the same clinic?
(Yes, it's fine to get records from different clinics. No, they don't need to be from the same clinic. In my case, I had from 1 clinic which took a blood sample test and checked for all the vaccinnations I have had)
4) Does it cause delays or other problems to get missing vaccinations at the time of the medical exam or should we make sure to do them ahead of time?
(You definitely need to get it ahead of time in order to save time and money. The problem if you don't get your vaccination record upon your medical exam is that they will need to take a blood test which will take some more time to process your medical statement. I know this for sure!!

Thanks for any help on these nagging questions!
