Antibodies are special type of proteins that can connect to viruses. It basically marks the virus so that immune system can shoot it down. Please let me know if

They do more than that. Some antibodies block off the part of the virus that is needed to infect a cell. https://en.wikipedia.org/wiki/Antibody#Function https://en.wikipedia.org/wiki/Antibody#Function

I wonder if they wouldn't worsen the immune storm

  This isn't Spanish Flu—there's no cytokine storm with COVID-19. That's why the deaths are almost entirely the very old and immunocompromised.

    really ? .. word of mouth was wrong then (how surprising.) is it bacterial infection post virus harm then ?

    > there's no cytokine storm with COVID-19. Could you provide a source?

      I don't know of anywhere that provides a comprehensive list of things COVID-19 isn't. Could you provide a source that suggests that there is one? Everything I've seen so far (eg, [0]) points to the virus itself damaging respiratory tissue, and normal body immune response aggravating that locally to some extent. A cytokine storm [1] is, as I understand it, a massive systemic immune overreaction causing way too much inflammation, overwhelming the body all at once. That Wikipedia entry suggests that SARS may have caused a cytokine storm, at least in some patients, but from it and everything I understand about the phenomenon, it's recognizable in epidemiology largely by the greatly increased incidence of deaths among young, healthy patients—which is not at all what we see in COVID-19.
