You are not correct according to Reuters. "The new schedule also recommends U.S. children receive a single dose of human papillomavirus (HPV) vaccine, rather than a two-dose course. Recent studies have concluded that a single dose is not inferior to the longer course and noted the World Health Organization also backs a single dose schedule." https://www.reuters.com/business/healthcare-pharmaceuticals/...

This clarification is missing from many others sources (such as the AP one I saw from a local news source): https://www.wral.com/news/ap/9b8df-us-drops-the-number-of-va... .

What you are describing is a somewhat routine adjustment and if it's non-inferior... sure. But it sure reads differently in different sources...

Interesting. In context that is not the claim what I am contradicting in the comment chain, despite that it is the literal reading of what I said.

The HPV single dose recommendation was probably coming regardless of who was in office.
