People cannot become truly knowledgeable without being excellent readers.

I never took a day off in my twenties. Not one.

Vaccines are a miracle; they're fantastic. Anything that makes people hesitate to give their children these vaccines according to the recommended schedule creates risk. Risk for the children who don't get vaccinated and risk for children, some of whom don't have an immune system, so they're benefiting from the fact that the community protection means the disease doesn't get to them.

We're very enthused about the idea that in the third trimester we actually give the mother a vaccine and her antibodies, the protective things that the immune system makes, actually pass through to the baby, both when the baby is born, and through the mother's milk. Because the baby's immune system is actually not very strong for that first few months, using the mother's immune system to do this - it's a very exciting idea and something that we're investing heavily in.
