Any vaccine only covers select strains. This vaccine is no different. They include the most prevalent strains at the time. Considering many women contract HPV from their spouse, don't even know they contracted it, and the husband didn't even know he had it in the first place, I think the vaccine is a good idea. It's not a license to have promiscuous sex. It's just a good idea. And given the reality of our situation, I think it is a step in the right direction. I certainly don't want it forced on anyone, though.
"They include the most prevalent strains at the time."
OR
They include the only strains that they have drupgs for. These two strains they "protect" one from MAY NOT be even high on the stats chart.
IOW, they deceptively market the only drug they have now and avoid talking details or even risks.
