I guess I will be spending the rest the flu season writing about the nonsense that is promulgated about the flu vaccine and the disease. One of the more common laments about the flu vaccine is that it doesn’t work: I got the flu vaccine and still got the flu. Well maybe. Maybe not. It takes a few weeks to get protection, so the flu could have developed before the antibody response to the vaccine. The vaccine does not protect to the numerous other viral infections that circulate each winter, so perhaps you had an adenovirus but thought it was the flu. Then there is the evidence. Some readers of the blog are worried that the literature does not support the use of the vaccine.
“My research for good studies on the efficasy (sic) of seasonal flu vaccines so far has left me wondering if I’ve somehow missed the good research. Tom Jefferson of the Cochrane Institute says that Most studies are of poor methodological quality and the impact of confounders is high. I agree. Please would you refer me to some of the best studies on the efficasy (sic) of seasonal flu vaccines. After a critical appraisal of the best studies you know of I’d like to submit the same for publication in the interest of science.”
Why some readers think I am a research librarian, I do not know. It is not an uncommon request. As an aside, I have a full time job and a family to raise. Don’t be asking me to do your grunt work. It’s called Pubmed. Use it.
But the topic for this post concerns the efficacy of the flu vaccine. I am limiting myself to the use of the vaccine in adults.
