"An Australian study has found the flu vaccine can almost halve the chances of a heart attack for middle-aged people showing signs of heart disease.
Researchers from the School of Public Health at the University of New South Wales found the link after examining more than 500 patients at Westmead Hospital in Sydney's west."
Probably has less less of an effect on us with our reduced responsiveness to vaccinations, but if this news encourages more people to seek flu vaccinations and thereby reduced the incidence of flu in the community, then that's still great news for us!
