Proved that the flu vaccine does not have any relation to narcolepsy
Controversy over the safety of the swine flu vaccine continues. A number of studies suggest that it sposobnavyzyvat rare disorder narcolepsy. It is a disorder of the nervous system characterized by bouts of irresistible sleepiness, sudden sleep, hallucinations.
The latest finding, after 5-7 months after the peak of flu incidence of narcolepsy increased. Employees of Stanford Medical School believe that the restriction in the use of the vaccine, designed originally to protect from narcolepsy, on the contrary, has led to increased morbidity, writes The Telegraph.
Expert Emmanuel Mignot commented: "In my view, recent studies suggest that it is the flu and bacteria Streptococcus pyogenes trigger narcolepsy. Therefore reducing the use of vaccines – wrong move that can increase the risk of disease." < / p>
Recall: after the swine flu pandemic in 2009, about 30 million Europeans have received the vaccine Pandemrix. Its safety raised questions among Finnish experts. Total found 335 cases of narcolepsy in people vaccinated with the vaccine. Later, the European Medicines Agency has recommended giving the vaccine to anyone under 20 years old, if they face the risk of swine flu. The analysis also showed that out of every 100,000 people vaccinated, seven can develop narcolepsy.
Now scientists emphasize that in all cases, was most likely a genetic predisposition, and the disease is provoked by an infection, affect their immune system. They surveyed 906 patients from Beijing, who was diagnosed with the disorder between 1998 and 2011 year.
Appeared onset was of a seasonal nature. Most often, it developed in April, and the least likely – in November, giving an effect usually six months after the seasonal surge in flu and colds. In all, from 2009 showed a threefold increase in the prevalence of narcolepsy. However, only 5.6% of the patients who participated in the study were vaccinated.
