Flu vaccine linked to high risk of narcolepsy in those under 30: study

Children are not the only ones at high risk of developing the chronic neurological disorder narcolepsy in conjunction with the pandemic swine flu vaccine Pandemrix, according to a new study. The latest among several in recent years to link the two, the new paper found that people age 20 and younger have a roughly tripled risk of developing narcolepsy if they get the H1N1 jab, while people 30 and younger have about a doubled risk.

Affirming what Sweden and at least a dozen other countries discovered several years ago, the study determined that for every 100,000 people vaccinated with Pandemrix, which is manufactured by GlaxoSmithKline, an extra four cases of narcolepsy develop among those 20 and younger. For those between 21-30, an extra two cases per 100,000 were observed, according to Sweden’s Medical Products Agency. (more…)
