Does the H1N1 vaccine cause narcolepsy?
Does the H1N1 vaccine cause narcolepsy?
Pandemrix, which is the swine flu vaccine that is manufactured by GlaxoSmithKline, is believed to trigger an immune response that may cause the onset of narcolepsy in rare cases. This reaction likely occurs due to the similarity of the H1N1 proteins and the neurons in the hypothalamus that produce the orexin hormone.
Can a virus cause narcolepsy?
The cause of narcolepsy is often an infection that “tricks” the immune system into destroying the cells that produce hypocretin by mistaking those cells for attacking bacteria or viruses. The infection might be nothing more than a sore throat or flu-like infection.
Is narcolepsy caused by vaccines?
An increased risk of narcolepsy was found following vaccination with Pandemrix, a monovalent 2009 H1N1 influenza vaccine that was used in several European countries during the H1N1 influenza pandemic. This risk was initially found in Finland, and then other European countries also detected an association.
What caused narcolepsy?
What causes narcolepsy. Narcolepsy is often caused by a lack of the brain chemical hypocretin (also known as orexin), which regulates wakefulness. The lack of hypocretin is thought to be caused by the immune system mistakenly attacking the cells that produce it or the receptors that allow it to work.
What produces narcolepsy?
What vaccines can cause narcolepsy?
Did they develop a vaccine for H1N1?
Both the injected vaccine (flu shot) and nasal spray forms of the vaccine against the 2009 H1N1 virus were produced and licensed by the Food and Drug Administration. The vaccine first became available in early October, and more doses are becoming available every week.
Is narcolepsy an autoimmune disorder?
There is increasing evidence that narcolepsy is an autoimmune disorder. Autoimmune disorders are caused when the body’s immune system mistakenly attacks healthy tissue or cells. In narcolepsy, the immune system destroys certain brain cells that produce a peptide called hypocretin.
