Fort Doge manufactures a MG vaccine and it is available through Jeffers Livestock Supply, where I bought my vaccines from. You could call Jeffers directly and ask if the vaccine is a live one or not. It can be given in the back of the neck under the skin (subcutaneously) and has to be given twice, so you would have to order two bottles of it. Once it's mixed, you have to throw away any left overs, so I'm guessing it is live. Again, I can't be certain so it's best to call and ask.
