“by age 50, at least 80 percent of women will have acquired genital HPV infection.”
It is also being hyped by pharmaceuticals who want to promote Cardicil, even though it only protects against a couple of strains, and has killed quite a few young women now.
It’s curious, that until recently, within the last 10 years or so, chlamydia wasn’t a sexually transmitted disease. Curious if you ask me.
