There have been 49 people who received the swine flu vaccine in 2010 who have now been diagnosed with the incurable sleeping disease, narcolepsy.
The Irish Medicines Board (IMB) is now waiting for information on further possible cases where clinical investigations are ongoing, and is actively following up to obtain this information.
From 2010 to date, the IMB has received 783 reports of suspected adverse reactions to Pandemrix, the majority of which are consistent with the known effects of the vaccine as described in the product information (information for all authorised products is on the IMB website).
The most frequently reported reactions included the following: 754 – nervous system disorders including dizziness, headache, fainting, and drowsiness; 485 – general disorders including fatigue, injection site reactions, temperature changes and weakness.
Other reactions include gastrointestinal disorders including nausea, vomiting, diarrhoea and abdominal pain; skin and hypersensitivity disorders including rash and allergic type effects; and musculoskeletal disorders including muscle pain and muscle weakness.
Many of the reports describe a number of reactions, so the number of reactions exceeds the number of reports.
