1. "Vaccines are safe" - The U.S. has the National Vaccine Injury Compensation Program [1]. In short it pays people who are hurt by vaccines. If vaccines are so safe why is this program needed?
2. "We had these vaccines as Kids" - The vaccine injury program made vaccine manufactures not be liable for injuries cause by their vaccine. This happened in 1988. "Since 1988, the U.S. childhood immunization schedule has rapidly expanded"[2]. In you are older than 28 you did NOT receive a lot of these vaccines as a kid.
There is a whole lot more but I don't feel like writing a book.
