I decided to go with three graphs this week, because statistical evidence is usually pretty convincing! All three of these graphs show thebenefits of vaccines including tetanus and polio graphs that show the number of cases decrease as the vaccine is introduced and used. The other graph shows the monetary benefits of vaccines compared to diseases. All three will benefit my argument.
