According to the CDC study vaccine effectiveness the seasonal flu vaccine is 62 percent. According to RKI effectiveness was in last season at 50 percent.

The U.S. Food and CDC (Centers for Disease Control and Prevention) in Atlanta published on 18 January 2013 a first preliminary study to vaccine effectiveness the seasonal flu vaccine for the flu season 2012/2013: According to the MMWR report vaccine effectiveness is the trivalent influenza vaccine for the Northern Hemisphere in the U.S. is currently at about 62 percent (MMWR, Morbidity and Mortality Weekly Report). Between 3 December 2012 and the second January 2013 participated in the study 1155 children and adults with acute respiratory infections (ARI or ARE for acute respiratory infection).

Antigenic drift – the RNA polymerase of swine flu That sucks

People suffer only sometimes reading disabilities, some enzymes suffer however always reading disabilities – for example, the RNA polymerase of influenza virus : The RNA polymerase of influenza viruses multiply the viral genome. Has RNA polymerase problems nucleotide punctuation, this leads to a point mutation, in a change of influenza virulence. virulence of influenza viruses are the surface protein hemagglutinin , and the two organic catalysts and RNA polymerase. As our human flu viruses change constantly through this so-called antigenic drift, is also the antigen composition of the seasonal flu vaccine to the World Health Organization (WHO) changed continuously. Therefore, the flu vaccine is reviewed annually and adjusted as necessary by studies annually.


Vaccine effectiveness of the seasonal flu vaccine in the U.S. is 62 percent

The CDC investigated now in 1155 people the effectiveness of the flu vaccine (vaccine effectiveness) against the seasonal circulating influenza viruses in five study centers of the American U.S. Influenza Vaccine Effectiveness Network (Flu VE): is this the antigen composition of the seasonal flu vaccine for the northern hemisphere is – in Germany, patients get the doctor the same vaccine composition as in the United States of America. The CDC now put down a provisional vaccine effectiveness of 62 percent. Almost every second vaccinated person can therefore currently ill with the flu in the U.S., although it has been previously vaccinated with the vaccine.

The influenza disease in vaccinated runs mostly without complications

Both the Standing Vaccination Committee (STIKO) at the Robert Koch Institute and the ACIP (Advisory Committee on Immunization Practices) recommended despite the moderate vaccine effectiveness a preventive flu shot. Scientific studies show that regular vaccination can improve the immune protection – in vaccinated individuals, the course of influenza illness is usually easier to occur less often in life-threatening complications. However, the scientific conclusions of such studies are further sustained. At least the science is ever more than in 1892: According to A. Ripperger for example, the English physician Brake Ridge observed during an influenza wave, “that the more affluent people have been struck more by the influenza as the poorer class of people, he concludes this from the that he had to deal with his private practice, over 200 cases of influenza, during the same hospital where he directed almost entirely absent. ” Such statements can also have quite different causes, such as socio-economic aspects.
