  • Flu Shot Lowers Heart Attack Risk By 19%



    why did they link the vax only to myocardial infarct but not to ILI or flu ?
    19% reduction, no matter how old ?

    ~1/4 of deaths in USA are from heart~
    so at least 4% reduction from all deaths from the vax ?

    and does early vaccination also result in better protection from flu
    or only in better protection from myocardial infarct
    I'm interested in expert panflu damage estimates

    Flu Shot Lowers Heart Attack Risk By 19%

    People who have the seasonal flu vaccine (flu shot) have a 19% lower risk of having a first heart attack, say researchers from the University of Lincoln, England, in a study that appears in CMAJ (Canadian Medical Association Journal). It appears that the earlier the vaccine is taken in the autumn the better the benefits are, the authors wrote.

    It has been suggested there may be an association between respiratory infections and heart attacks - both increase in incidence significantly in the winter months when flu and pneumonia are prevalent.

    The British researchers . . . found a link between those who had been vaccinated and a significant reduction in heart attack risk. The pneumococcal vaccination was not linked to any additional benefit, the authors added.

    Those who were vaccinated between September and mid-Novembers (early vaccinations) had a 21% heart attack reduction risk, while patients who received the vaccination later had a 12% reduction risk.

    The authors wrote (in conclusion):
    Influenza vaccination but not pneumococcal vaccination is associated with a reduced rate of first acute myocardial infarction. This association and the potential benefit of early seasonal vaccination need to be considered in future experimental studies.
