  In a recent Letter [B. K. Sahoo, B. P. Das, and H. Spiesberger, Phys. Rev. D
103, L111303 (2021)], a calculation of the parity violating 6S-7S E1 amplitude
in Cs is reported, claiming an uncertainty of just 0.3%. In this Comment, we
point out that key contributions have been omitted, and the theoretical
uncertainty has been significantly underestimated. In particular, the
contribution of missed QED radiative corrections amounts to several times the
claimed uncertainty.
