I just wanted to also add some anecdotal information in regards to
breastfed babies and chicken pox.  My mother, as a teenager, contracted a
severe case of chicken pox and was hospitalized because of the severity
of her case.  Her case developed into a severe systemic chicken pox.
i.e. chicken pox on her organs, inside her eyes ect.  Anyway, after about
25 years she had a titer run and the count was so high she was asked if
she had just recovered from the pox.  Mind you, this is 25 years later!
In the meantime, my sister and I were lucky enough to hav been
breastfed.  I was nursed for 18 months and my sister for 12 months.  Our
mother exposed us time and time again to children with active cases of
chicken pox and neither one of us ever came down with them.  When I was
pregnant with my second child, I was exposed to chicken pox 2 times.
Once at the beginning of the pregnancy and once about a month before
delivery.  I received the varisel (sp?) globulin shots both times.  But
before they would give me the shot they ran a titer and found that sure
enough I had never developed any antibodies.  Is it possible that given
the severity of my mothers case that maybe my sister and I were somehow
protected in utero and subsequently through breastfeeding that has lasted
into our adulthood?  BTW my sister tests negative also.  Be interested to
know if my children who also have been exposed but not come down with the
pox could somehow be protected.
