If it were a live vaccine then avoiding humans would do the trick, id think. Im not sure these gene therapy "vaccines" shed like that tho? Ya know i really think truthallday's comment is whats going on here... every women knows about how when youre around a bunch of other women your menstral cycles start synchronizing, it really could be that womens bodies are signaling to each other that its not a safe time to be having children. I know i said that in kind of retarded way, sorry. Anyway, that may accohnt for irregularities but im not sure about the miscarriages, seems like it would take more than that.
