Helen McShane: Women in science

A career in juggling, organisation and guilt management Professor
Helen McShane has been working on a new TB vaccine for 10 years.
There are about 9 million new cases and 1.7 million deaths every
year from tuberculosis. She developed MVA85A, a vaccine with the
aim to boost the cellular immune response induced by BCG.
Developing countries are especially in need of a new vaccine since
HIV and TB epidemics overlap and show a devastating synergy.
