Parents and children have come out in support of a family battling for the Meningitis B vaccine to be given to all children - after their daughter died from the illness earlier this year.
An online petition calling for the move has become the most signed in Parliamentary history, following the death of two year old Faye Burdett in February.
Andy Dickenson reports and speaks to Faye's parents Neil and Jenny, and Rachel Cattell, organiser of today's event.
The parents of a toddler from Kent who died from meningitis B gave heartfelt evidence to MPs today, as they called for the vaccination programme to be expanded.
Faye Burdett's parents released a picture of their daughter in hospital as she fought the infection after the 2 year-old died on Valentine's Day this year.
Her death prompted hundreds of thousands of people to sign a petition backing the couple's campaign for the vaccination programme to be extended. Sarah Saunders reports.
