  We compare the results of the SuSAv2 model including meson-exchange currents
(MEC) with the recent measurement of the quasielastic-like double differential
antineutrino cross section on hydrocarbon (CH) performed by the MINERvA
Collaboration. The relativistic nature of the model makes it suitable to
describe these data, which correspond to a mean beam energy of 3.5 GeV. The
standard SuSAv2 model predictions agree well with the data without needing any
additional or tuned parameter. The role of longitudinal MEC is non-negligible
and improves the agreement with the data. We also consider the impact of
different treatments of the $\Delta$-resonance propagator in the two-body
currents on the data comparison.
