Australians warned to vaccinate against fast-spreading flu variant

Infectious disease specialists are urging everyone to get a flu vaccination to try to prevent a repeat of last year which saw Australia experience a record number of deaths from influenza. More than 1,700 people died and there were more than half-a-million confirmed cases. Health experts say low vaccination rates are contributing to the higher case numbers. They're warning this year could be even worse because of the spread of influenza subclade K or Super-K.
