Evidence continues to mount:

A new study published online on Nov 15, 2008 and scheduled to appear in the July 2009 issue of Cancer Causes & Control suggests that some vaccines may increase risk of cancers such as non-Hodgkin lymphoma, while others may reduce the risk.

The study led by H. A. Lankes and colleagues at Feinberg School of Medicine of Northwestern University showed influenza vaccination was linked to a 53 percent increase in the risk of NHL.

Lankes and colleagues analyzed data on 387 patients with NHL and 535 controls who were enrolled in a study conducted in Nebraska between 1999 and 2002. Considered information included vaccination for tetanus, polio, influenza, smallpox, and tuberculosis, as well as important environmental factors – data collected by telephone interview.

They found that study participants who had an influenza vaccine at any time were at a 98 percent increased risk of follicular lymphoma and at an 88 percent increased risk of diffuse large B cell lymphoma.

Interestingly, it was the flu vaccine that appeared to increase risk, while a lowering of some lymphoma risks seemed to follow the polio and smallpox vaccines. (There was no change with respect to tetanus and TB vaccinations.) And, obviously, this should be of some concern, especially upon considering that the powers-that-be recommend getting flu shots every year…and that the call for this has gotten stronger since H1N1 (a/k/a “swine flu”) came on the scene. The current study thus gives yet another reason to forgo the jab. (For others , see this and this.)
