@biobook I'm not sure which piece you're struggling with.
Thanks for showing up! Here's what I didn't understand - It's in the article itself, not the abstract. In the Results for Model 3, they say that the people who recovered from covid and were vaccinated had a
significantly decreased risk, but then in the Discussion, say the decrease was
not significant. Are they referring to the same thing in both sentences? What am I missing?
Results:Examining previously infected individuals to those who were
both previously infected and received a single dose of the vaccine, we found that the
l
atter group had a significant 0.53-fold (95% CI, 0.3 to 0.92) (Table 4a) decreased riskfor reinfection, as 20 had a positive RT-PCR test, compared to 37 in the previously
infected and unvaccinated group.
Discussion:Individuals who were previously infected with SARS-CoV-2 seem to gain additional
protection from a subsequent single-dose vaccine regimen. Though this finding
corresponds to previous reports24,25,
we could not demonstrate significance in our
cohort.
