I remember this vaccine being part of political discourse, so I everyone should be extremely skeptical of any news about it.
At one point, it was encouraged that 9-year-olds get the vaccine. As a parent, I'd rather my child wait until their immune system is more developed, with the idea being that if they're getting STDs at age 9, then there's a bigger problem.
The thought that a 9yo would need protection from STDs is very upsetting which I would guess makes it a talking point. It is better to mass vaccinate at whatever age is publicly acceptable than not at all so I would concede that to critics.
Anyone exposed to sexual activity at such an age is clearly a victim of abuse. Penalising victims of abuse, whether it be forcing them to attempt to carry a baby to term, against medical advice, or forcing them to deal with the consequences of STDs is a very peculiar and nasty attitude. When societies start justifying denial of care and treatment along lines of class, politics, age, race, religion, gender or perceptions of "morality" there's a bigger problem.
