Comment on "On the implementation of CVC in weak charged-current proton-neutron transitions" by C. Giunti, arXiv: 1602.00215 [hep-ph]

We show that the term maintaining conservation of the charged vector current for the transitions "neutron <-> proton" even for different masses of the neutron and proton (see T. Leitner et al., Phys. Rev. C {\bf 73}, 065502 (2006) and A. M. Ankowski, arXiv:1601.06169 [hep-ph]) is related to the first class current contribution but not to the second class one as has been pointed out by C. Giunti, arXiv: 1602.00215 [hep-ph].
