Each year, about 31,000 men and women in the U.S. are diagnosed with a cancer caused by an infection from the human papillomavirus, or HPV. It's the most common sexually transmitted virus and infection in the U.S.

In women, HPV infection can lead to cervical cancer, which leads to about 4,000 deaths per year. In men, it can cause penile cancer. HPV also causes some cases of oral cancer, cancer of the anus and genital warts.

Metro Health is offering free vaccines this summer to 11 and 12-year-olds participating in the Parks and Recreation Summer Youth Program.  

Science tells us vaccines are one of the greatest inventions of the last 150 years. They've all but eradicated deadly diseases like smallpox, polio, and measles from most of the world.

Vaccines are a treatment designed to arm a person against those viruses and other diseases by providing immunity. They work by exposing you to a weakened version of a pathogen, like a flu virus. Your body's immune system then learns the pathogen's characteristics and develops the necessary antibodies to resist the pathogen if later exposed to it.

In the past few months, there have been several outbreak of mumps in Texas — a handful of cases linked to a Halloween party in Dallas, other cases to a cheerleading contest in Arlington.
