The High Court has approved a settlement of €1.3 million in the case of a teenage girl who claimed she developed the rare sleep disorder narcolepsy after the swine flu jab.

The 14-year-old cannot be identified.

It is the latest in a number of settlements agreed before the High Court for young people who took legal action after developing sleep disorders and muscle weakness following the Pandemrix vaccine.

The court heard the girl got the Pandemrix vaccine twice, first in November 2009 and again in 2011 when GPs were advised they could give Pandemrix as a flu vaccine.

Her lawyers told the court the girl has severe narcolepsy and cataplexy and suffers from excessive daytime sleepiness and zones out while at school.

She will need medication for the rest of her life and had to give up all sports.

Senior Counsel Jonathan Kilfeather said the girl has a very high IQ and had wanted to study medicine after school but she will now have to go in a different direction.

The girl had through her mother sued the Minister for Health, the Health Service Executive, and Glaxosmithkline Biologicals SA (GSK) - the producer of Pandemrix.

GSK was previously given an indemnity by the State concerning any adverse reactions to the vaccine.

Mr Justice Paul Coffey said he had no hesitation in approving the settlement and wished the family well.
