It is said that motherhood transforms women. That isn’t merely a statement; there is a modicum of truth there as the moment we hold the little bundle of joy in our arms, its like the entire wiring in our brains changes. For example, when I was a new mother I was very interested in everything that was related to child care. After all I was in charge of lots of decisions. One such decision was vaccination and the kinds of vaccines deemed the safest and most effective. The kind of research I did, would put an earnest PhD student to shame. Which brings me to the topic I want to talk about today: vaccines that don’t have preservatives.
