Link help, please re: ineffectiveness of flu vaccine

post #1 of 3
Thread Starter 

Could someone please help me with a link from a reliable source about very low effectiveness of seasonal flu vaccine? I remember seeing this link stating that 90+% of all flu like illnesses are caused by other strains than those in vaccine. but now when I really need this link I cannot find it. Help me please!

That is one summary of thier findings on Flu vaccines: You can search their website for more.

Cochrane reviews are a gold standard for doctors so it is a good source.

 

Also, the authors attempted to find and investigate every study that has evaluated the effects of flu vaccines in healthy adults aged 18-65. To this end, they “searched Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2010, issue 2), MEDLINE (January 1966 to June 2010) and EMBASE (1990 to June 2010).”

 

They included 50 reports. Forty of them were clinical trials adding up to over 70,000 people. Two reported only on harmful effects and were not included in this study. Studies of all types of influenza vaccines were included: live, attenuated, and killed—or fractions of killed—vaccines.

 

Their conclusion:

"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."

 

 

Other summary:

***They found no evidence that vaccination prevents viral transmission in healthy adults! (There goes the whole herd immunity argument!) This is particularly significant because, as they noted, inactivated vaccines are known to perform best in healthy adults.

***They also found no evidence that flu vaccines prevent complications, either. They attempted to ascertain the degree of complications, and though they did report on some, most of the studies simply did not address the issue or did so inadequately.

***Vaccines administered parenterally, that is, outside the digestive tract—which generally means by injection—reduced influenza-like symptoms by only 12%.
