No offense, but you're just too naive to be making a post like this. Anti-vaccination is considered by many doctors to be child abuse imposed on children by their parents. There are no "opposing opinions" when hard data supports one "opinion". Science isn't about belief systems, it's about replicable testing of data, and good research supports the use of vaccines.

Being anti-vaccination is similar to admitting, "I am an under-read, highly suggestible individual who considers anecdotal statements as true evidence and more important to me in my decision-making than the scientific method." It's simply due to a lack of good education, or an omission of good information in public schools.
