Flu Vaccine Efficacy

One weird trick to avoid the 'flu.

One weird trick to avoid the ‘flu.

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.

Even with the H1N1 pandemic flu strain going around, you should still be vaccinated against the seasonal flu

Even with the H1N1 pandemic flu going around you should still be vaccinated against the seasonal flu. revere has the details. Read. Enjoy. Be educated.

I guess that means Dr. Doug Bremner must think that revere is an idiot. After all, Bremner tells us that the flu vaccine is all a plot for big pharma to make money, don’t you know? Subtlety and weighing of risk-benefit ratios in a manner that doesn’t turn into an anti-big pharma rant is beyond him, as both Peter Lipson and I discussed (and Peter discussed again) not too long ago.

Fortunately it is not beyond revere to rationally weigh the risks and benefits of being vaccinated:

The truth is this. No one knows what’s going to happen. We’re all guessing. But in my estimation, the risk-benefit calculation for vaccine side-effects and flu is so markedly in favor of the vaccine that I made the decision to get vaccinated and that’s what I’d advise others, too. How confident am I? I’m confident it is the most rational thing to do given what we know.

Exactly. It is quite possible to look at the evidence and science and decide that the risk-benefit ratio is so much in favor of vaccination that it makes sense to be vaccinated. It’s also possible to look at the same literature and be less enthusiastic. You don’t need to appeal to big pharma conspiracy theories, and, in fact, such appeals only muddy the issue unnecessarily.

I’d love to see Bremner try to counter the arguments of a highly respected senior epidemiologist who can calmly discuss the pros and cons of flu vaccines from a scientific and practical standpoint based on evidence. Bremner points to “experts” who say that vaccination against the seasonal flu is a waste of money and time, but here’s one expert I bet that Bremner can’t refute. I won’t hold my breath waiting for him to try, though. It’s so much easier just to say that you’re an idiot if you get vaccinated against the seasonal flu. Obviously, in Bremner’s world, revere must be in the thrall of big pharma and pro-vaccination ideology.

Just like me, I guess.
