Sorry, nope.
Best suggestion is to go to the CDC link and poke around to find the guidelines; and then find the older guidelines somewhere.
Yeah, I thought of that, but it would be too much work for the people I am attempting to reach with this flyer.
I am hoping to find some source that offers sort of an apologetics for this change in the hopes that some people who read it might say, “Now, hold on one gosh darn minute. This seems a bit bonkers.”
