The biggest challenge with this project was to choose information that the public would find interesting and understandable. We wanted to provide detailed, specific information without being dull or actuarial. I was guided by Dr. Laura Helft, Science Outreach Specialist for the Howard Hughes Medical Institute. We took great care to make the calculations as accurate, conservative, and as honest as possible. Please spread the word about the importance of vaccines against debilitating and deadly diseases like Rubella, Polio, Whooping Cough, Measles, Mumps, Shingles, & Meningitis.
