Meningitis vaccine on iodine supplementation

I am taking a trip and I just found out I need a meningitis vaccine.

Will this interact with my Iodine supplementation?
Will it affect my mercury levels?
Will it be a starting point for Alzheimer or any other disease? Or will I be alright?

Will my hormones be affected by it?

If pregnant women should not take it (it could affect the fetus), could it harm women who may become pregnant and give birth to a life? Especially someone trying to heal her womb (uterine fibroids)?

There is no way around it unless I forgo my vacation.
