| A) | 775 individuals will be prevented from developing the disease in question. | |
| B) | the relative risk reduction of the disease is -775 among those who were vaccinated. | |
| C) | 775 individuals must be vaccinated to prevent one case of the disease. | |
| D) | vaccinated individuals have a 1-in-775 chance of developing the disease. | |
