Not currently pg, but I was 5 years ago. my thoughts on pg women getting a flu shot are this: I feel it's a dangerous thing to do. It is not known how the ingredients in vaccines effect developing brains, and it's not worth the risk for me. I stick with washing my hands and eating well. There are lots of natural immune support supplements available, which I would (or do, rather) use when I feel it's needed.
My 2 cents.
