Explanation:
Detailed explanation-1: -Neutralizing antibodies can inhibit infectivity by binding to the pathogen and blocking the molecules needed for cell entry. This can be due to the antibodies statically interfering with the pathogens, or toxins attaching to host cell receptors.
Detailed explanation-2: -Neutralizing antibodies are responsible for blocking the entry of a pathogen into a cell so that it is firstly unable to infect healthy cells, and secondly, it is unable to replicate and cause severe infection.
