This documentary about Down's syndrome and the ethics of pregnancy screening was met with critical acclaim when it was screened on BBC last year. If you missed it then, now is your chance to check it out. Fronted by Sally Phillips, A World Without Down's Syndrome? explores the science and ethical implications around screening tests for Down's syndrome. It is a subject matter that is close to Sally's heart, as her own son, Olly, has Down's syndrome. Here, she talks to experts in the Down's syndrome community and the world's top scientists, while people with Down's syndrome also participate in the debate around this thorny subject.
