So far, the mass vaccination campaigns against SARS-CoV-2 are considered the most convincing solution that would ease the pressure on public health systems, and swiftly return to normal activities. Study has shown that once more than 70% of the population is immunized in each country, the health crisis could finally be brought under control.  

As the vaccine starts to roll out globally, how to measure the effectiveness of vaccine has become a major topic recently. Neutralizing antibody is the indicator that can tell the effectiveness of vaccine.  

¿Qué es el anticuerpo neutralizante?

A neutralizing antibody (NAb) is a type of antibody that is produced naturally as part of immune system responses. These antibodies inhibit the effects of or destroy foreign agents that invade the body.  

Neutralizing antibodies can be triggered by infection or vaccination. It can block the interaction between the receptor-binding domain (RBD) of the novel coronavirus spike protein with the ACE2 cell surface receptor.  Therefore, the level of Nab can be used to analyze a patient's immunity against future SARS-CoV-2 infection. In that case, if a neutralizing antibody is tested in a patient's body, it indicates that the vaccine is effectively injected.
