(NaturalNews) A live virus nasal flu vaccine known as FluMist (made by AstraZeneca) is failing to provide protection to children, and its manufacturer is blaming the vaccine's total inefficacy on high temperatures rather than exaggerated quack science.

When the supposedly "fragile" shot is set out at room temperature for too long, the "swine flu" portion of the jab apparently loses its potency, claims AstraZeneca. As a result, the attenuated vaccine fails to provide the claimed protection against influenza.

FluMist is currently approved for individuals aged 2 to 49 and has long been touted as resistant to temperature fluctuations. But now, in an attempt to uphold the official story that "all vaccines are safe and effective," AstraZeneca is changing its story.

When the quadrivalent form of FluMist was first approved by the Food and Drug Administration (FDA) back in 2012, the federal agency claimed that it offered "an additional option to aid in influenza prevention efforts." However, this clearly isn't the case for swine flu.

"At a medical meeting Thursday, Feb. 26, 2015, company officials said they investigated and concluded that the swine flu part of the vaccine is unusually sensitive to heat," explains U.S. News & World Report.

Advisory Committee on Immunization Practices withdraws preference for FluMist

Last June, the Advisory Committee on Immunization Practices (ACIP) made a recommendation that young children should get the nasal spray flu vaccine rather than the traditional injection flu vaccine. This recommendation came after the FDA and AstraZeneca alleged that FluMist was safe and effective.

It was also based on the assumption that FluMist is capable of provoking a stronger immune response in children who have never been sick with the flu, a position that has since been challenged due to the failure of FluMist to provide the claimed protection.

Following AstraZeneca's announcement that FluMist doesn't work when it gets too warm, ACIP reportedly pulled its preferred recommendation for the nasal spray vaccine and reverted back to recommending injection flu vaccines instead.

FluMist and other flu vaccines may be completely useless, suggests government health officials

Based on data presented at the recent meeting, it was determined that all flu vaccines, including FluMist, simply aren't as effective as claimed. For this past year's flu season, all available flu vaccines were found to be only 20 percent effective, at best.

But more recent data show that this year's flu vaccines were only 18 percent effective, with one CDC panel suggesting only a 15 percent efficacy rate. And as far as nasal spray flu vaccines, there simply isn't any evidence available to suggest that they even work at all.

"Studies can't confirm that the [nasal] vaccine has a benefit," stated Dr. Joseph Bresee, chief of the Epidemiology and Prevention Branch at the CDC's National Center for Immunization and Respiratory Diseases.

"These low numbers, which are lower than we normally see, are because the flu viruses that are circulating have mutated to look very different than the vaccine strains," he added, affirming the possibility that vaccines may be directly to blame for flu virus mutations.

Still, despite these dismal numbers for injection-based flu vaccines, and the utter failure of nasal spray flu vaccines, health officials are urging the public to get flu shots rather than fortify their health naturally with sound nutrition, plenty of water and regular sleep.
