On the flu vaccine & boosting your immune system

There hasn't been much for me to write about lately, except for the [lousy] weather and it's contribution to my feeling of malaise (which I'm not going to bore you with today), but now that the winter season is upon us, and with it the heightened awareness of the greater potential for getting sick, this seemed like the perfect opportunity to post some information I think might help us all get through this season in far better shape.

If you have cancer, the question of the efficacy of the flu vaccine has always been a controversial one. Most oncologists will tell you to get vaccinated, because it won't do any harm, and it may be effective, but now there is evidence to support that belief.

The available literature shows that patients with cancer do mount an immune response to influenza immunization. It is unclear, however, whether this response is as robust as that seen in otherwise healthy persons. The CDC recommends annual influenza vaccination for this patient population. Preliminary data suggest that influenza vaccination between cycles of chemotherapy may be more effective than vaccination on day 1 of chemotherapy. Larger, well-designed prospective studies are needed to assess the efficacy of the influenza vaccination in patients with cancer, and the optimal timing of vaccination relative to chemotherapy administration.

There was also this article from the New England Journal of Medicine, on why everyone should get the flu vaccine, which I unfortunately am unable to fully access (the link is only for the first 100 words), but to paraphrase:

.....vaccination decreases the likelihood that an exposed person will pass virus on to others. If sufficient numbers of people can be vaccinated in time, an epidemic can be slowed or even stopped in its tracks.

And finally from the NY Times on how not to fight a cold. This article was published on the op-ed page, but there is a lot of evidence to support this theory (including the two links in the side bar of this blog on why boosting your immune system is not a good idea).

[A] susceptibility to cold symptoms is not a sign of a weakened immune system, but quite the opposite. And if you’re looking to quell those symptoms, strengthening your immune system may be counterproductive. It could aggravate the symptoms by amplifying the very inflammatory agents that cause them.
