IIRC, in one of the COVID rescue bills passed, there was a specific exemption for organizations protecting them from suits for people being infected as part of operation.
That said, in the US, pretty much anybody can pursue a suit against anyone for anything at any time - the waivers help to discourage such and may help later as evidence of informed consent toward *defending against* the case.

Have there been dance groups sued because someone caught Covid at a dance? Is that what a waiver prevents? How did they prove they caught it at the dance?
