The original version [1] of this article contains errors in Tables 2 and 3 as follows:

In Table 2: Because of a formatting error, the mean values of three peptides in Set 2 were listed under Set 1 and the mean values for Set 3 were listed under Set 2.

In Table 3: The values under “Positive” and “Negative” columns for the row describing “SARS-CoV-2 negative nasopharyngeal swab samples (n = 30)” were switched and the “Specificity” was incorrectly represented as “~ 100%” instead of “100%.”

The authors regret these errors, which have now been corrected. The corrected Tables 2 and 3 are given.
