Summary:
Older adults are at high risk for serious complications from flu and account for a majority of flu-related deaths and hospitalizations. H3N2 influenza viruses typically hit this age group particularly hard and have been associated with higher mortality than infections by H1N1 or influenza B viruses. During the 2012-2013 season, when H3N2 viruses were dominant, high-dose flu vaccine was 36 percent more effective at preventing deaths in the Medicare beneficiaries studied, compared to standard-dose vaccine.

FULL STORY
The high-dose flu vaccine appeared to be more effective at preventing post-influenza deaths among older adults than the standard-dose vaccine, at least during a more severe flu season, according to a large new study of Medicare beneficiaries published in The Journal of Infectious Diseases. The findings build on earlier research suggesting that the high-dose vaccine may be better at preventing influenza virus infections and other flu-related outcomes in seniors, including office visits and hospitalizations, compared to the standard-dose vaccine.
