Indeed. Unsurprisingly, they did make some notes about this in the study: "We were unable to estimate the effect of vaccination and infection year on long COVID symptoms in our study due to the very short follow-up period among those vaccinated and infected in the year 2022 (median 8 (IQR 4–14) and 12 (7–16) days, respectively) compared to those unvaccinated and infected in the year 2021 (33 (16–77) and 64 (31–90) days, respectively). Furthermore, the majority (81%) of patients vaccinated before infection in our cohort were infected with SARS-CoV-2 within 2 weeks of vaccination, which would be before acquiring immunity from vaccination, thus restricting the validity of our data to assess the effects of vaccination on long COVID." https://www.nature.com/articles/s41591-022-01909-w https://www.nature.com/articles/s41591-022-01909-w > ... it'd be great to see a large study like this of vaccinated people. I, too, am very interested in further research in this area, because it will strongly inform my actions now and for the next couple of years. As noted above though, it's frustrating, but it sounds like it's way too early.
