Thanks for the source, I hadn’t seen it before. 90% risk reduction is still an order of magnitude, seems like a big deal to me.
One point to be aware of: I notice they don’t distinguish between the different vaccines, they just give a population-wide figure. The UK has used a combination of Pfizer and AstraZeneca, and on other metrics eg efficacy against symptomatic infection or hospitalisation, AZ is slightly to moderately worse than Pfizer. Assuming the same pattern holds for long covid, I would assume a >90% risk reduction for Pfizer (and Moderna with similar mRNA technology), which is the read-across relevant to American readers.
