Everything in plain text is UNCHANGED from the 2005 (existing) version of the IHR. Everything bolded (except section headings) is new language (= amendments).

There are two major arguments (and many minor ones that I have previously detailed here and here) that the WHO has not followed its own procedures and therefore:

1. the decision about the IHR yesterday should be null and void because the final targeted set of amendments was not presented to the member nations 4 months ahead of their consideration, as required by IHR Article 55 paragraph 2, and
2. the amendments passed in 2022 were not voted on in the plenary session and therefore should be null and void

* * *

This means every nation has at a minimum 10 months to avoid any provisions it does not like in the newly amended document. It simply has to write to the WHO and say it rejects whatever it does not like. In the US, the next President can do this until April 1, 2025.
