@kristinHenry I was not vaccinated during my childhood. Only later when I had children of my own. Why? Even though views had changed my parents were still deeply influenced by their Jehovah's Witnesses faith that had taken an anti-vaccine stance in the 1930s. I myself was a JW until I left that faith in 2007. But yes indeed, vaccines have been an incredible advance in disease prevention. Cheers, -Randy
