there are many vaccines, I am guessing you are asking about the vaccine
for Human Papilloma Virus (HPV). This was introduced into the United
States around 2009.
The World Health Organization (WHO), as well as public health officials
in Australia, Canada, Europe, and the United States recommend
vaccination of young women against HPV. HPV vaccination is also
effective in males to protect their partners from HPV infections,
as well as themselves from anal cancer and genital warts, and possibly
other HPV associated cancers.
vaccines have market approval in many countries as of 2014 (called
Gardasil and Cervarix in the US). Both vaccines protect against the two
HPV types (HPV-16 and
HPV-18) that cause 70% of cervical cancers, 80% of anal cancers, 60% of
vaginal cancers, and 40% of vulvar cancers. These HPV types also cause
most HPV induced oral cancers, and some other rare genital cancers.
