hello. i have a 5 month old baby and i am thinking about waiting on some vaccinations and not giving others. chicken pox is one of the ones i am considering not giving the chicken pox vaccination, but a family friend who is a doctor suggested that kaleb's x-linked could lead to a much more severe chicken pox if he got it. to the point that it could be life threatening. does anyone have any info or first hand experience with chicken pox and x-linked? thank you.
