What causes you to to have an immunity to chicken poxs?

My niece has chicken poxs again. This makes her 3rd time and she is 12. The last time she had them the dr said she had an immunity to them, but someone at dr office (not dr) said she needed to see a specialist because it could be a sign of lukemeia, has anyone else heard of this. she has no other health problems.

Update:

It was the same rash and the same dr all 3 times. They did bloodwork to determine that she has no immunity to the virus.

    Argument 1.

    It is not possible to get chickenpox twice - the argument claims that a single chickenpox infection provides subsequent lifelong immunity

    Argument 2.

    If immunity was lifelong then shingles would not occur since this represents a localised reactivation of the virus (indicating a failure of immunological control of latency)

    True re-infection with chickenpox is very rarely reported.

    Leukemia and chicken pox are not at all related to each other.

    Impetigo - bacterial skin infection, begins with small blisters. Rule out to exclude impetigo.

    Anyone who has chickenpox is immune, usually for life. An exception being if she got them before she was a year old then she could have them another time. But 3, no. Not even if she had leukemia.

    The reference to leukemia comes because if a person has leukemia and gets chickenpox, it can be dangerous to them.

    ******Response to your added details..........

    So she never had chickenpox in the first place. Whoever diagnosed the rash as chickenpox was wrong.

    the in uncomplicated words element you'd be data against is getting hen pox lower back. That reported, the virus lays dormant on your nerves and once you grow old, you probably will improve shingles.
