What do antibodies actually do to a virus
Dvinal [7]

Answer:

It neutralizes the virus

Explanation:

When a vertebrate is infected with a virus, antibodies are produced against many epitopes on multiple virus proteins. A subset of these antibodies can block virus infection by a process that is called neutralization.

Antibodies can neutralize viral infectivity in a number of ways, as summarized in the illustration. They may interfere with virion binding to receptors, block uptake into cells, prevent uncoating of the genomes in endosomes, or cause aggregation of virus particles. Many enveloped viruses are lysed when antiviral antibodies and serum complement disrupt membranes.
