Tatyana weighs twice that much and she takes 12.5 mg of Cortef. Anyway best way to know the answer to your question would be to ask your Endo. Does seem risky to me, at one time I thought about getting the hepitisis vaccines (there’s 3 in a series) and I decided against it out of fear of actually getting the condition due to the fact that my immune system could have been compromised by the higher than necessary dose of Dex that I used to take.

 Btw, my daughter was out on Cortef after she had all her shots.......so I can’t really answer your question from experience. Hopefully some of the other Mom’s will shed some more light onto the situation for you. Take care......good luck
