Those book "bans" are just librarians' decision on what to use finite shelf space to stock. Students are 100% free to bring any of the "banned" books to school and read them. By this logic, when a librarian changes out an older set of YA novels with a newer set, those older novels are being "banned". So to answer your question:

> Cool, so the US students will be able to read school banned books ?

The answer is "whenever they want."

Furthermore, the CDC's calls for retraction don't prohibit anyone from reading the retracted papers.
