Hi Virginia,
Yeast lives in our GI tracts.  Having a vaccine made with yeast will not make
the recipient at risk to developing thrush.  If a baby does develop thrush
this is based on them becoming susceptible and maybe introduction to ABM's
could do this because this baby would lose the protective coating that breast
milk gives to their gut.
I asked the neonatologist about this and she said that yeast is used as a
base in many things and does not cause thrush.
Hope this helps. :-)  Since no one else has written about this I am assuming
that others are in agreement.
