Hi I would like to know if a person can be immune to the chicken pox? Because When I was younger my oldest stepsister contracted the chicken pox which let to my second oldest sister getting the chicken pox two days later then my sister got the chicken pox. The family doctor advised my father to deliberately have me catch the chicken pox. My father had me use the same cups exchanged saliva. And quarantined me with my 3 infected sisters in the basement which very small room for the whole entire time they had the pox until they were better. It was a few weeks between the 3 of them. And I also had direct rubbing rash to skin And I did not contract the chickenpox.What she leads me to my question. Can I be immune to the chicken pox and if I am an i contract shingles?
