The [best source I’ve found] (https://institute.global/policy/hidden-pandemic-long-covid) finds a 30% reduction in P(Long COVID | infection after 2 vaccine doses). Infection reduction is about 85%, so total risk reduction is about 90%, MUCH less than the risk reduction for hospitalisation.
The study is based on 3,000 infected patients, all over 60, unclear how it generalises to younger people.
In general, there is SOME good quality research on long COVID, and it seems obvious to me that it is a legitimate thing and respects a good fraction of the harm of the pandemic. Even if overall research is much less high quality than I want.
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.
