It appears that COVID-19 can also enter cells (these would be immune cells that came to 'help') via so called Fc-pathway.
Therefore allow the virus to multiply even more

In addition to viral entry via ACE2, antibodies against coronavirus spike proteins (anti-spike-S-IgG) can induce antibody-dependent enhancement (ADE) of viral entry via type II Fcγ receptors. ..." [1]
