For example, the pertussis vaccine is known to cause side effects of crying, a fever and seizures, and the rotavirus is associated with intussusception ("The Benefits of Vaccination Outweigh the Risks"). While it is true that the pertussis vaccine can cause the side effects described above, in a study in Japan there were only 400 cases of pertussis and 10 cases of death when vaccinated. While when there was no vaccination there there about 13,000 cases and 113 deaths. That’s over 3x the amount of cases and 11x the death toll ("The Benefits of Vaccination Outweigh the Risks"). The rotavirus vaccine although associated with intussusception, a painful condition in which the intestine folds into another intestine, has no impact on the chance of a person contracting intussusception. Whether a person is vaccinated or not, they have the same chance of getting intussusception ("The Benefits of Vaccination Outweigh the Risks"). Another, concern that parents might have is the fact that some vaccines have thimerosal (a derivative of mercury). While some vaccines do have thimerosal, it is also true that it is contains the smallest amount (less than a trace) of it and is put in to prevent bacteria from entering the vaccine vial. Even after injection the thimerosal is not easily transported across the blood and is quickly excreted by the body ("Evidence Shows Vaccines Unrelated to
