i work at a very busy place where i talk to many people each day --so i know many people who got this flu that is going around and many of them had told me that they usually never get the flu or have not had one in years but happen to catch this one. i think this flu is a very strong or different type of strain. after talking to all the people i have talked to about it i would have to say that it has nothing to do with the mms lowering the immune system, in my opinion. i just think it is a strong flu this year. it also seems to have a number of different symptoms than usual flu's and it seems to last a lot longer. some people even said they had it for two or three weeks. we got it in our family too but with mms it was short lived.
