In the 1960s five-year-old Jeryl Lynn Hilleman got ill with mumps. Her father Dr Maurice Hilleman took a swab from the back of her throat and used it to help create a vaccine for the disease - more quickly than any previous vaccine had ever been completed. During his decades long career Dr Hilleman worked on vaccines for measles, mumps, rubella, chickenpox, hepatitis and meningitis.
