Nae, Fairly sure I mentioned in a thread that when I was readong about antibodies when I had my brush with WC while pg with Phoebe, in canada they have taken to vaccing new mums in the hospital after the birth. In 10 days the antibodies are in the BM and bubby is indirectly assisted by this until their vaxs. So if you are going for your booster, get it right after you have bubs.
