At present I'm a non-vaccinater for a few reasons, but if I were your friend and you asked me to either get the booster or not see the baby, I wouldn't take offence. I almost died getting the WC vaccine so I would decline the booster, but I would respect your decision and your stance. Of course I would be sad that I didn't get to visit your newborn, but I wouldn't be offended.

One important thing to remember though is that one of the main strains of WC going around at the moment is not protected by the vaccine. So vaccinated people are just as likely to get it as non-vaccinated people. My two step sons (and possibly my DH) got whooping cough about a year ago. All three are "fully" vaccinated. My son and I were the only two in the house not to get it, and we are the only two not vaccinated against it.
