Re: Latest HPV vaccine info (little girl forced vaccine)
I think some of you guys are a little confused as to the etiology of cervical cancer;
Certain strains of HPV lead to DNA damage which causes cervical cancer; this temporal causality has been extensively proven in large scale clinical studies.
Of the many strains of HPV, relatively few cause cervical cancer. HPV 16 and 18, are the cause of 50% and 20% of cancers respectively. I think this is where people are getting the "70%" figure. HPV 35 and 41 both cause ~5% of cancers.
As a result of this, a quadrivalent vaccine which protects women against these 4 strains would effectively reduce the incidence of cervical cancer by 80%.
As to "forcing" girls to get this vaccine, I think the fact that HPV is sexually transmitted is besides the point. The fact that preventing a large portion of such a horrible disease is within our grasp is reason enough. If you are cruel enough to blame a 25 year old girl who is dying of cancer for having unprotected sex when she was 15, you need to reexamine your own values.
