Supernanny and parenting expert Jo Frost has joined the UN Foundation's Shot@Life campaign as a Global Advocate, aiming to support fundraising and raise awareness about the need for global life-saving childhood vaccines in developing countries.

Frost commented 'From crawling, talking, dropping off at school, birthdays and their first injections - childhood vaccinations are a rite of passage for most of us, but for some that is not the case, as millions of children globally die every year from a vaccine preventable disease. With just a small change we can make a huge impact'.
