🌜Midnight Cat 🐈⬛Dear Susan: Is there any study done that shows which countries have the largest number of people who are opossed or against vaccines? My family began a discussion about the large number or people we see here in the United States that fight day and night against vaccines, making life for the rest of us difficult. I know that a couple of decades ago, this was unheard of. And while growing up, my family would have never dreamed of refusing a vaccine.
