Um, yeah, NO. I could list a whole bunch of reasons why Amy's science is wonky, but NO. I had a friend who flat-out asked anyone if they'd had their T-DAP recently before having that person around her newborn, and I wasn't offended in the slightest. Hells, if I hadn't just had it a year before, I would have welcomed the reminder. We all make choices, and we all live with the consequences. It sounds like the LW is prepared to accept lost friendships as a result of her actions, so one would assume the anti-vaxxers would be likewise. If not, they should be. And Amy can just stuff it.
