Re: your disclaimer: thank you for posting this.  We need to leave room for people who are cautious in reasonable ways, as you are describing.<p>When our child was born in 2002, there was a lot of &#x27;buzz&#x27; about the dangers of vaccinations.  Most of it we were quickly able to filter out, but there was a body of research that had strong correlations between lower incidents of a whole variety of early childhood problems in &#x27;1st world&#x27; countries that didn&#x27;t vaccinate as early and aggressively as the United States, such as Japan and some part of northern Europe.<p>We decided to not vaccinate until our son was five years old, an age when he was getting into more crowded social situations.  And he has been current ever since.<p>We weren&#x27;t 100% convinced that the broad spectrum and very early age vaccinations in the United States were a problem, but we weren&#x27;t convinced otherwise.  At the same time, we knew that vaccinations are an absolutely critical part of modern society.<p>Like you, we made some conservative BUT WELL REASONED decisions regarding our child.<p>That kind of middle of the road thinking needs to be way more commonplace.<p>Sorry for totally hijacking your post. :)
