The only one to blame for that is Merck itself who did all the high dollar lobbying to bring about the mandates. They were finally, and appropriately, shamed into halting their campaign which had nothing to do with the dangers of HPV, but rather their own financial bottom line.
No question Merck was clumsy and heavy-handed in their initial marketing of this vaccine. A case study in how to do it wrong. But this doesn't show the vaccine is unsafe or ineffective, just that Merck has a lousy PR staff.
