Default Cochrane Collaboration: Flu Vaccines of No Benefit

Cochrane Collaboration: Flu Vaccines of No Benefit
10 October 2012
http://www.ahrp.org/cms/content/view/876/9/


The negative finding of a comprehensive review of 50 published reports by the highly credible Cochrane Collaboration should discourage healthy people from getting a flu shot. This is the season that many Americans are advised-even pressured--to get flu shots. Indeed, flu shots are being hawked at every drug store chain...
But what does the evidence show about the effectiveness of the flu vaccine when vaccinated and unvaccinated groups are compared ?

Well, the finding of a comprehensive review of 50 published reports by the highly credible Cochrane Collaboration should discourage healthy people from getting the flu shot:

"The results of this review seem to discourage the utilisation of vaccination against influenza in healthy adults as a routine public health measure.
As healthy adults have a low risk of complications due to respiratory disease, the use of the vaccine may be only advised as an individual protection measure against symptoms in specific cases."

Specifically, the EVIDENCE REFUTES the claims that the flu vaccine prevents the flu;
the EVIDENCE REFUTES the claim that it prevents viral transmission in healthy adults;
and the EVIDENCE REFUTES the claim that the vaccine prevents complications and "saves lives."

The EVIDENCE shows little or no benefit for influenza vaccinations.

"This review includes 15 out of 36 trials funded by industry (four had no funding declaration). An earlier systematic review of 274 influenza vaccine studies published up to 2007 found industry funded studies were published in more prestigious journals and cited more than other studies independently from methodological quality and size. Studies funded from public sources were significantly less likely to report conclusions favorable to the vaccines. The review showed that reliable evidence on influenza vaccines is thin but there is evidence of widespread manipulation of conclusions and spurious notoriety of the studies. The content and conclusions of this review should be interpreted in light of this finding."

Repeat:
“…industry funded studies were published in more prestigious journals and cited more than other studies…”
“…reliable evidence on influenza vaccines is thin…”
“…there is evidence of widespread manipulation of conclusions…”

Most assuredly, the “content and conclusions of this review should be interpreted in light of this finding”!

So, it would be prudent to be highly skeptical about the pronouncements and recommendations of public health officials about the value or necessity of various vaccines.

There are hidden financial conflicts of interest.

Something tells me not to buy that argument..,

What do recent vaccine effectiveness studies show?

CDC conducts studies each year to determine how well the flu vaccine protects against flu illness. These estimates provide more information about how well this season’s vaccine is working. Recent studies show vaccine can reduce the risk of flu illness by about 60% among the overall population during seasons when most circulating flu viruses are like the viruses the flu vaccine is designed to protect against.
http://www.cdc.gov/flu/about/qa/vaccineeffect.htm

I am pretty certain that this measure is weighed against laboratory confirmed infection with specific strains..,

Whereas, the Cochrane Collaboration reported:

Quote:
Over 200 viruses cause influenza and influenza-like illness which produce the same symptoms (fever, headache, aches and pains, cough and runny noses). Without laboratory tests, doctors cannot tell the two illnesses apart. Both last for days and rarely lead to death or serious illness. At best, vaccines might be effective against only influenza A and B, which represent about 10% of all circulating viruses. Each year, the World Health Organization recommends which viral strains should be included in vaccinations for the forthcoming season.
They are artificially skewing the focus of the study AWAY from conformational measurement and making their conclusions based on a very broad spectrum of illness.

Of course, "INFLUENZA VACCINE" won't be effective or efficacious under a measure like that.

By the way, INFLUENZA is a specific disease and is NOT caused by over "200 viruses." Another point where the focus is skewed away from measuring the ACTUAL effectiveness of INFLUENZA VACCINE against ACTUAL INFLUENZA.

No agenda there though..,

I don't buy that the AHRP is living up to it's mission.

Vaccines for preventing influenza in healthy adults
Plain language summary
http://onlinelibrary.wiley.com/doi/1....pub4/abstract


Over 200 viruses cause influenza and influenza-like illness which produce the same symptoms (fever, headache, aches and pains, cough and runny noses). Without laboratory tests, doctors cannot tell the two illnesses apart. Both last for days and rarely lead to death or serious illness. At best, vaccines might be effective against only influenza A and B, which represent about 10% of all circulating viruses. Each year, the World Health Organization recommends which viral strains should be included in vaccinations for the forthcoming season.

Authors of this review assessed all trials that compared vaccinated people with unvaccinated people. The combined results of these trials showed that under ideal conditions (vaccine completely matching circulating viral configuration) 33 healthy adults need to be vaccinated to avoid one set of influenza symptoms. In average conditions (partially matching vaccine) 100 people need to be vaccinated to avoid one set of influenza symptoms. Vaccine use did not affect the number of people hospitalised or working days lost but caused one case of Guillian-Barré syndrome (a major neurological condition leading to paralysis) for every one million vaccinations. Fifteen of the 36 trials were funded by vaccine companies and four had no funding declaration.

Our results may be an optimistic estimate because company-sponsored influenza vaccines trials tend to produce results favorable to their products and some of the evidence comes from trials carried out in ideal viral circulation and matching conditions and because the harms evidence base is limited..
