Gardasil (HPV vaccine) coverage and safety in the United States
Genital human papillomavirus (HPV) is the most common sexually transmitted infection (STI) in the USA. There are more than 40 HPV sub-types that can infect the genital areas of males and females. These same HPV types can also infect the mouth and throat. They are transmitted from personal contact during vaginal, anal or oral sex.
Some HPV subtypes, such as HPV-6 and HPV-11, can cause warts around the genitals or anus, but have low (but not 0) risk of causing cancers. However, the higher risk subtypes, such as HPV 16 and 18, not only cause approximately 70% of cervical cancers, but they cause most HPV-induced anal (95% linked to HPV), vulvar (50% linked), vaginal (65% linked), oropharyngeal (60% linked) and penile (35% linked) cancers. HPV is estimated to be the cause of nearly 5% of all new cancers across the world.
According to the CDC, roughly 79 million Americans are infected with HPV–approximately 14 million Americans contract HPV every year. Most individuals don’t even know they have the infection until the onset of cancer.Read More »Gardasil (HPV vaccine) coverage and safety in the United States
