  In a recent paper we showed that the decay of intermediate $\bar{\Lambda}_b$
baryons can dramatically enhance the antihelium flux from dark matter
annihilation. Our antihelium predictions were derived using several
implementations of the Pythia and Herwig event generators which were calibrated
to existing data on antideuteron and antihelium formation. Kachelriess et al.
have argued for a smaller antihelium flux compared to our most optimistic Monte
Carlo model. However, we show that the arguments by Kachelriess et al. are
either incorrect or irrelevant for antihelium formation. Thus, the results of
our original paper remain unchanged.
