Lowering your risk for Alzheimer's can be as easy as taking ibuprofen, and in the event of a pandemic, who gets treated first? Plus new findings for the HPV vaccines.

Although the HPV vaccine is approved for girls starting at 9 years-old, a new study indicates many mothers aren't inclined to give the shot to girls that young. The HPV vaccine marketed as Gardasil, protects against the human papilloma virus, which can cause cervical cancer.

The CDC recommends girls get the vaccine before they become sexually active, as experts say HPV is often acquired soon after. While 86% of surveyed moms said they intended to vaccinate their 16 to 18 year-old daughters, just 48% say they would have their 9 to 12 year-olds get the shot.

In the event of a pandemic, who should be treated and who should not, if treatments are scarce? A group of experts from various universities and government agencies, has come up with pandemic recommendations. Those include decisions such as which patients would essentially be sacrificed and not get life saving treatments. Such patients include, the very elderly, those with severe trauma or burns, and those with advanced dementia or severe chronic disease, such as late stage lung disease.

Taking ibuprofen may lower your risk for Alzheimer's disease, researchers at Boston University School of Medicine compared nearly 50,000 veterans with Alzheimer's to those without the disease. They found those who used ibuprofen for more than five years had an over 40% reduced chance of developing Alzheimer's. Other pain relievers in the same drug class as ibuprofen did not show this benefit.
