Labs around the country are hunting for an influenza super-shot that could eliminate the annual fall vaccination in favour of one every five years or 10 years -- or maybe, eventually, a childhood immunization that could last for life.
he number of flu cases is continuing to rise across Canada, suggesting the peak of infections with one of the dominant circulating strains could come within a few weeks -- or even sooner, say infectious diseases experts, who describe this influenza season as 'unusual.'

Controversial 'vaccinate or mask' policies that force nurses to get a flu shot or wear a surgical face mask for the entire flu season are based on flimsy science that lacks credibility, according to new analysis.
