Prevention and Attenuation of Covid-19 with the BNT162b2 and mRNA-1273 Vaccines ( vol 385 , pg 320 , 2021)

Prevention and Attenuation of Covid-19 with the BNT162b2 and mRNA-1273 Vaccines (N Engl J Med 2021;385:320-329). In the "Attenuation of Viral RNA Load with Vaccination" subsection of Results (page 325), the second sentence should have read, "The mean viral RNA load was 3.8 log(10) copies per microliter among unvaccinated participants and 2.3 log(10) copies per microliter" rather than "... 3.8 log(10) copies per milliliter ... and 2.3 log(10) copies per milliliter." In Table 3 (page 327), the unit for the mean viral RNA load should have been log(10) copies/mu l rather than log(10) copies/ml. The article is correct at NEJM.org. . . .
