Vaccines are 100% effective and 100% safe.
Pro will contend for the resolution.
I, Con will contend against the resolution.
Vaccine "Vaccination: Injection of a killed microbe in order to stimulate the immune system against the microbe, thereby preventing disease. " 
Here is the definiton of Vaccine: "a substance used to stimulate the production of antibodies and provide immunity against one or several diseases, prepared from the causative agent of a disease, its products, or a synthetic substitute, treated to act as an antigen without inducing the disease."
I say Vaccines are 100% safe! They eliminate multiple diseases and keep people from getting sick or maybe even killed.
"The measles vaccine, for example, is one of the most effective at 93% (for those who have had only one dose of the vaccine) and 97% (for those who have had two doses, which is the recommended amount). Why?"
I conclude that vaccines are not 100% effective nor 100% safe.
I've heard that vaccines are 100% safe on the news and everywhere else!
Vaccines are one of the greatest success stories in public health. Through use of vaccines, we have eradicated smallpox and nearly eliminated wild polio virus. The number of people who experience the devastating effects of preventable infectious diseases like measles, diphtheria, and whooping cough is at an all-time low. To ensure the continued success of vaccines in the United States, it’s crucial to make sure that vaccines are safe.
Before vaccines are approved by the Food and Drug Administration (FDA), they are tested extensively by scientists to ensure they are effective and safe. Vaccines are the best defense we have against infectious diseases; however, no vaccine is actually 100% safe or effective for everyone because each person’s body reacts to vaccines differently.
You just made a Con argument by admitting that there are risks. Thanks for the debate.
I am all for it! I just stated that vaccines eliminated polio virus, good luck on the voting! You did good!
