#6 Live Attenuated Influenza Vaccine for Children as Young as Two Years

Overview

Nasal drops containing live attenuated flu can be used as a vaccine in lieu of needles, and provide effective protection from influenza for this high-risk population.
During the past year, studies have demonstrated the increased efficacy of live influenza vaccines, while the nasal route of delivery (bypassing needle administration) is especially valuable in children. This expanded the U.S. patient population by 10 million. However, use of live attenuated virus was not approved for children aged six months to two years.

Where Are They Now

Nasal drops containing live attenuated flu can be used as a vaccine in lieu of needles, and provide effective protection from influenza for this high-risk population. A live attenuated influenza intranasal vaccine for the novel H1N1 influenza virus was approved by the FDA in 2009.

In June 2016, the CDC’s Advisory Committee on Immunization Practices (ACIP) voted that the live attenuated influenza vaccine should not be used during the 2016-2017 flu season. The decision stems from the vaccine’s efficacy slip from prior estimate as published in June 2017.
