A new study has found that the FluMist nasal delivery system is just as reliable as other forms of a vaccine:
It came as a surprise this June when the Centers for Disease Control and Prevention recommended against using the nasal flu vaccine for the 2016-2017 flu season, citing a lack of evidence that it works. Now, findings from a Canadian study [DOI: 10.7326/M16-0513] appear at first blush to contradict the research that led the Advisory Committee on Immunization Practices [ACIP] to recommend against that live attenuated vaccine.
But things aren't so simple. In fact, the conflicting evidence about the live nasal flu vaccine offers an excellent case study on how complex the task of analyzing flu vaccine data and making recommendations really is. "Sometimes the public wants a very simple message, and unfortunately life's not like that," Mark Loeb, the new study's lead author and director of the division of infectious diseases at McMaster University in Ontario, tells Shots. "Things change as the evidence grows and we understand more. Unfortunately, that's how science and clinical medicine work. The challenge is to be able to help the public understand the shades of gray here."
[...] CDC data consistently showed the live nasal vaccine to be very effective in children until 2013, when the vaccine went from including three strains (trivalent) to including four strains (quadrivalent). And therein lies the rub: The new Canadian study used the trivalent vaccine, while ACIP analyzed data using the quadrivalent vaccine, and among U.S. children. "Many of us felt very strongly that the LAIV [live attenuated influenza vaccine] was a better vaccine than the inactivated for children, and the data supported that," says Pedro Piedra, a professor of virology and microbiology at Baylor College of Medicine and one of the investigators involved in the nasal vaccine clinical trials in the late 1980s. "But something happened when it became a quadrivalent vaccine."

Yes, which is precisely the sort of thing we need to know. I mean, do people want flu that can be fitted nasally?

I think we should look at the link between corporations that only want profit forcing vaccines on the people. There has been an alarming rise in autism. Some question whether there is a link, this man included.

This is just bizarre...look at "Appendix table 2" in the paper (http://annals.org/article.aspx?articleid=2543271). This paper reports data indicating that neither vaccine does much of anything, but they just don't discuss that aspect at all. I suppose one way of spinning their result is that the two methods "work just as well" as one another. Actually the people who got vaccinated had a higher chance of testing positive for influenza (6% vs 5 %).

Hey, that's a great marketing idea.
"Buy my new medicine! It works just as well as snake oil, at half the prize!"
And the best, nobody can sue for false claims, as the statement is absolutely true (assuming the prize statement is)! ;-)

Competing on price is a difficult business model to sustain. It ends up being a race to the bottom, where, pretty soon, you end up selling commodity placebos for commodity prices. Look to homeopathy for a better marketing plan. (Hint: it involves bullshit for added value)

People tested positive for influenza after squirting "live" influenza viruses up their noses? Impossibru!

Since testing positive for influenza was the primary endpoint, I would hope they accounted for that somehow. Too bad it is behind a paywall...

That may be how clinical medicine works, but not science. In science you design things so the result of your study is to get an ever closer approximation of reality. The NHST approach to research, used here (and is standard in clinical research), has been well known to automatically lead to apparently conflicting evidence for many, many years. The only reason this pandemic of conflicting evidence isn't more apparent are the institutionalized resistances to replication studies and publishing "negative" results.

Protip: the results of studies always represent reality correctly. The problem lies in trying to induct general models from those results.

Thanks. I meant to say "models that are ever better approximations of reality".

They represent the answer to the exact question arising from the setup, which is too often unrelated to the actual intent and/or interpretation.
Like most computer bugs.

yeah right! it was only a suprise to dumbasses or liars. the cdc recommends against using a method where your body might be able to keep their soft kill weapons from working. how are they going to inject cancer viruses and god knows what else straight into your baby's blood if you don't let them start shooting them up with bioweapons as soon as some demented quack cuts them out of the mother's belly like a fish? It's no suprise the vaccines didn't work either. Anyone with any sense already knows it's not about stopping any disease.

By the inject cancer viruses, I think they are referring to the HPV vaccine.
Though I guess they never read "The Red Queen" by Matt Ridley or
they would have a slightly different take on vaccines and their role in our genetic diversity.

"The Red Queen" doesn't directly cover vaccines, and it is good to keep skepticism.

Some polio vaccines prepared from 1954 to 1961 were contaminated with infectious SV40.
-- https://www.ncbi.nlm.nih.gov/pubmed/16288015 [nih.gov]
Studies in the 1960s showed that SV40 could produce certain cancers in newborn hamsters. More recent studies reported finding SV40 genes in several types of human tumors. These findings have raised the question of whether SV40 may cause, or contribute to causing, some types of cancer in humans. Several epidemiological studies found no link between exposure to SV40 contaminated vaccines and development of cancer. However, a study of immunization of pregnant women showed an increase in certain cancers in the offspring of women immunized with IPV compared to women immunized with either OPV or influenza vaccine. However, a recent report by the Institute of Medicine of the National Academy of Sciences concluded that "the evidence is inadequate to accept or reject a causal relationship between SV40 containing polio vaccines and cancer."

sv40 is just one small example where their absurd stupidity and arrogance got them noticed.
watch Silent Epidemic - The Untold Story of Vaccines for one thing. i'm not against the idea of vaccines, btw. just sick of the medical industry and the prostitutes (at best) at the cdc.
