New research on the the human papillomavirus vaccine shows it can protect against the sexually transmitted virus for at least eight years.

HPV is thought to cause the majority of cervical cancers. The virus is also believed to cause genital warts in both men and women and certain head and neck cancers.

Among the vaccinated preteens in a new study, none developed any of the diseases or conditions associated with HPV during the study period, the researchers reported.

The researchers also said "all indications" are that the vaccine is safe.

The full vaccine comes in three doses, and the Centers for Disease Control and Prevention recommends that both boys and girls between 11 and 12 get them.

Despite the vaccine's benefits, only about 57 percent of girls age 11 to 15 are getting the first dose of the vaccine, and only 33 percent are getting all three doses. Among boys, about 34 percent are getting the first dose and only 14 percent are getting all three doses, according to the CDC.

For vegetarians, dairy and cereal can help

If you follow a vegetarian diet, you should make sure you are getting enough nutrition.

Doctors say the biggest concerns are getting enough protein, calcium, iron and Vitamins D and B-12.

Greens, whole wheat bread and fortified cereals contain iron. B-12 is in milk, eggs and some cereals.

Vitamin D is in dairy products.

Flax seed has omega-3 fatty acids. Experts often recommend adding it to meals.

Childhood mental disability cases on rise

Childhood mental health disabilities are on the rise.

A study reveals there was a 21 percent increases between 2001 and 2011.

Some of those included attention deficit hyperactivity disorder, autism, epilepsy, intellectual impairment and learning disabilities.

The study also revealed that the majority of the children with those conditions were from poverty-stricken backgrounds.

One of the reasons for the increase: Families have better access to health care, and more children are getting a diagnosis and treatment.
