Fig. 6: Logarithm of the number of genomic copies estimated based on ORF1ab gene.

a Non-vaccinated versus vaccinated groups. b Wild-type virus versus Alpha variant. Log, logarithm in base ten. The dashed line represents the median of the log of genome copies; the solid lines below and above each rectangle represent, respectively, the first and the third quartiles; adjacent lines to the whiskers represent the limits of the 95% confidence interval; small circles represent outside values.
