Newest study about bivalent effectiveness is probably this one: https://www.cdc.gov/mmwr/volumes/71/wr/mm715152e1.htm

If you want to stay up to date on vaccine effectiveness without wading through a bunch of misinformation, just listen to the weekly "TWIV Clinical update with Dr. Daniel Griffin" podcasts. Here is the most recent one: https://www.microbe.tv/twiv/twiv-967/

For a slightly different perspective on the bivalent boosters, here is Paul Offit (member of the FDA vaccine advisory committee, and one of the two votes against authorizing the bivalent boosters for everybody) talking in detail a couple weeks ago about his current view of the bivalent boosters: https://www.microbe.tv/twiv/twiv-special-offit/.

I would try to summarize what I think is the most accurate view right now based on the science, but honestly there is just too much nuance and too many unknowns to do so concisely, other than I don't think saying they are "duds" makes a whole lot of sense. But I would just listen to the experts on the podcasts who will go into the nuance better than I can.
