Time to get that flu shot! When you get a vaccination during the day, consider taking a sleeping pill before you go to bed that night, because a new study shows that poor sleep can reduce the effectiveness of vaccines. In fact, sleep duration is directly tied to vaccine immune response.

It’s time to get your flu shot! But it may not be as effective if you’re overweight. A new study provides evidence explaining a phenomenon that was noticed for the first time during the 2009 H1N1 flu outbreak: that obesity is associated with an impaired immune response to the influenza vaccination in humans.

Representative Michele Bachmann, who may be the Republican candidate in 2012, has been quoted as saying that the vaccine to prevent cervical cancer is "dangerous." Meanwhile, her husband runs a religious clinic that tries to turn gays "straight." It turns out that pediatricians in Appalachia are less likely than doctors in other areas to encourage parents to have their children receive the human papillomavirus (HPV) vaccine, despite studies showing that Appalachian women are more likely to get cervical cancer and to die from it than women living elsewhere. Could this be a religious bias borne out of a fear of encouraging sexual promiscuity in adolescent girls?

Some incredible vaccines are arriving soon, including one that could help you quit smoking and another that might prevent women from getting breast cancer. And new DISSOLVING microneedles mean they won’t hurt, either.

Researchers say they’ve developed a vaccine prevents breast cancer from developing in mice–will it work for human women? BBC News quotes immunologist Vincent Tuohy as saying, “We believe that this vaccine will someday be used to prevent breast cancer in adult women in the same way that vaccines have prevented many childhood diseases. If it works in humans the way it works in mice, this will be monumental. We could eliminate breast cancer.”
