CDC Recommends against Nasal Spray Flu Vaccine

According to William Schaffner, MD, an infectious disease specialist and Professor of Preventative Medicine and Medicine at Vanderbilt University Medical Center, FluMist has fallen out of favor because "[t]o everyone's surprise and increasing consternation, this vaccine has performed quite poorly compared to the injectable vaccine."
The CDC found that the live attenuated flu vaccine was virtually ineffective during the 2015-2016 flu season after FluMist was changed from trivalent (three-strain) to quadrivalent, while the inactivated flu injection was 49% effective against any flu strain.
A Canadian study published in the Annals of Internal Medicine on Aug. 16, 2016, found that a trivalent version of FluMist was 46-58% effective against the virus. AstraZeneca, the manufacturer of FluMist, cited similar effectiveness results and stated that the company was "working with the CDC to better understand its data to help ensure eligible patients continue to receive the vaccine in future seasons in the US."
The National Vaccine Information Center, a nonprofit educational organization, stated: "It is shocking that government health officials have devised a National Vaccine Plan that lobbies for every single American to get a flu shot from cradle to the grave before the real science is in. Putting vaccine policy before the science is bad public health policy. Conducting uncontrolled vaccine experiments on people, who have been taught to believe and trust government health policy and now are being forced to obey strict 'no exceptions' vaccine laws, has far reaching consequences."
