I grew up in a home with a mother who believes that vaccines （疫苗） cause brain damage，and do not contribute to the health and safety of a society.The only shot I received was for tetanus （破傷風(fēng)） when I was two months old.After that，nothing.
   At the beginning of each school year，I was very nervous.Delayed term paper？Mischievous （搗蛋的） behavior？Late for school？None of them.I'd be pulled out of class and brought to the headmaster's office.The school doctor would tell me I hadn't received any of the necessary shots to attend school.But the same thing occurred each time：my mom would free me from the shots and nothing would happen.
   After doing a lot of research，I found although people who don't vaccinate their children make up only a relatively small group，they can cause major consequences.People who，for health or age reasons，cannot receive vaccines are at a higher risk of catching a preventable disease.
   Eventually，I turned 18.In Ohio，where I live，I had to wait until I became a legal adult to make the decision to receive vaccine shots.A huge factor in taking the step to ensure my health was the message board website Reddit.Last November，I asked Reddit users for advice about what vaccines to ask for and how to go about getting them from a doctor.After my post received more than 1，000 comments，I made an appointment with my family physician.Despite how strongly my mother felt，I went through with it anyway.
   I did something every person should do.It wasn't special in any way.Vaccines protect the health and safety of not only yourself but also other people.Vaccination is important because someone could die if you don't get vaccinated.This was the biggest reason I got vaccines despite the opposition.
