Hi Mingke Yu, I don't know if one of us could rightfully answer the
question for you. However, I think that you may realize that the
answers are contained within the question. I know that Ohio State has
Medline because I've been there. If I were you, I would get on the
terminal and do a couple of quick searches for "replicon and vaccine or
recombinant vaccine." You will have to do the digging yourself but I'm
sure you will find the answers that you need.
Best of luck.
