Early data on vaccine effectiveness promising as U.S. flu season approaches
This season’s flu vaccines for the Southern Hemisphere have reduced the risk of being hospitalized for flu by 52%, based on mid-season data from five countries, suggesting the U.S. vaccines could provide similar protection if similar viruses continue to predominate, the Centers for Disease Control and Prevention reports. Both hemispheres used similar flu vaccine formations. The CDC recommends all Americans aged 6 months and older get the seasonal flu vaccine in September or October.
