Long COVID risk and pre-COVID vaccination in an EHR-based cohort study from the RECOVER program -...

LTC Eugene Chu
..."Key points: Question: Does vaccination prior to COVID-19 onset change the risk of long COVID diagnosis?Findings: Four observational analyses of EHRs showed a statistically significant reduction in long COVID risk associated with pre-COVID vaccination (first cohort: HR, 0.66; 95% CI, 0.55-0.80; OR, 0.69; 95% CI, 0.59-0.82; second cohort: HR, 0.62; 95% CI, 0.56-0.69; OR, 0.70; 95% CI, 0.65-0.75).Meaning: Vaccination prior to COVID onset has a protective association with long COVID even in the case of breakthrough infections."

LTC Eugene Chu there are going to be studies for decades (longitudinal) about the Covid vaccines. Results will vary depending on where you got your info

So... I'm looking at the charts. That's seems like quite a spread. Until you look at the Y axis. The difference in round umbers, less than 2%.

Why do you think they cut off the y axis below .96 on a 1.0 scale?
