My mom has worked in the immunization clinic for years, providing all kinds of vaccines for lower income families.
If a vaccine such as this were mandated certainly the sliding scale would apply to it.
I for one am just glad someone spent some time working on a medicine that has nothing to do with men being able to have a sustainable hard-on. Next, lets work on ovarian cancer, that highly deadly and barely perceptible killer. Or lets work on detecting breast cancer without smashing a woman's breast in two.
I had a friend who died of cervical cancer when she was 34 years old. That is 8 years younger than I am now, though she was older than me at the time. I was mid 20's.
If it weren't too late for me to get said vaccine, I would be banging down the door right now to get it. Women's cancers scare me.
