The parents of a teenager from Fulham who died from an allergic reaction have launched a £10million prize for allergy research.

15 year old Natasha Ednan-Laperouse died in July 2016 following a severe allergic reaction to Pret A Manger sandwich.

Sesame was not listed as an ingredient on the packaging and the seeds were not visible to the naked eye.

Natasha’s parents have since successfully campaigned for a change in the law.

It requires food outlets to provide a full ingredients list and allergy labelling for foods made and packaged on the premises for direct sale.

The aim of Natasha’s Prize will be to “create a future without allergies”.

Scientists from across the world are invited to apply for the prize to create solutions aimed at preventing food allergies.
