W.,
Yes, you can get the chicken pox after the shot, but having them three times really is not in the normal range. (Having the shot is like having a mild case.) So what to do?
Ask your pediatrician to draw a titre on your daughter to see her level of immunity.Her immune system may be weaker than most and she may need booster shots on things like mumps and measles also. You should realize that your ped. won't suggest this on his own you really need to ask for it. Also you might want to address why your daughters immune system isn't as strong as the adverage kid.
Good luck.
