As of a few years ago, a new variety of Gardasil, called Gardasil-9 was approved by the FDA and it induces immunity against more varieties.

That's excellent! I had not heard of the newer version, thanks for the info! I was very happy when I saw that they finally started recommending parents vaccinate boys as well as girls. I never understood the initial hesitance. Sure boys might not have to worry about cervical cancer, but HPV is the #1 cause of oral cancer in males. And that's on top of just the general 'if you can protect your child from a prevalent disease with minimal risk, why wouldn't you?'

Nine of them, as one could easily deduct. There's dozens of HPV strains, most of them relatively harmless.
