Answer: Let me tell you why there was so much opposition to the idea of a vaccination from my personal experiences.
Explanation: A vaccination is putting a dead or weakended version of the virus you are getting vaccinated for, a lot of people do not like the idea of putting a virus inside of them. Also from personal experience my mom has stopped getting vaccines, the reason is is because every time she gets one she gets sick with the virus. Therefore she has not gotten a vaccine in the best 4-5 years.
