I support the vaccintation 100%. As part of my post m/c medical investigations my wonderful ob/gyn discovered that I was not immune to chicken pox. The vaccination 'apparently' takes 3 months after you are vaccinated to settle into your system. For someone ttc 3 months is like 3 years! If they get the vaccination while they are young then 3 months will pass just as quickly as 3 minutes. I thought my ob was mad telling me to get it at 28yrs of age then I met a client who was over 35 and had recently caught cp! Then i saw the method in his madness and was thankful for his advice.
