New Study – Flu Vaccine Doesn’t Work

A new study confirms yet again what many prior studies have shown [see list at end], that ‘flu vaccination is largely ineffective [despite what Government “health” officials want you to believe – but where of course will they be looking for their next job when they retire at 50 on generous government pensions]:  Jefferson T, et al. Vaccines for preventing influenza in healthy adults (Review). Cochrane Database Syst Rev. 2010 Jul 7;(7):CD001269.

Julie Gerberding head of the US Centres for Disease Control – budget US$11 billion – the US agency charged with promoting vaccines [CDC] following her removal by President Obama went directly to become vaccine maker Merck’s Director of Vaccines Division in December 2009: Dr. Julie Gerberding Named President of Merck Vaccines – 21 Dec 2009 – Merck & Co., Inc.

Here’s a plain language summary of the Oxford based Cochrane Collaboration recent study in the authors’ own words:

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.

The authors warn that industry-funded studies are more likely to be unreliable but be published in prestigious journals and cited more frequently than more reliable independent studies. Here’s what they say:

WARNING:
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.
