Each year, as autumn is well underway, seasonal influenza
vaccinations become a topic of conversation for everyone in
general and for those with children in particular. At this year’s
meeting of the CDC’s Advisory Committee on Immunization
Practices (ACIP), citing preliminary data regarding the vaccine
effectiveness of the vaccines in use during the 2015-2016
seasons, the committee noted that the downward efficacy
trend had continued. Walter Chalkley, Senior Editorial Project
Manager for Cortellis Regulatory Intelligence, discusses how
CDC is working not only with the manufacturer, but also with
the US Food and Drug Administration, the US Department of
Defense, and other public health organisations to determine
the cause.
