Whoops. sorry about the mom/dad confusion. I'm so used to talking to moms. But, wow.. egg allergies and thimerisol don't count anymore? The freaking world is allergic to thimerisol, and the amounts are boatloads more than acceptable and in a more toxic form. it' horror story. I love sharing what I know so that people can see their options. But, it's a rabbit hole. It's much more empowering to look at all of the amazing ways we can boost our immunity and actually live in harmony with nature.... as apposed to trying to eliminate every bug.
