Abstract COVID-19 mRNA vaccine BNT162b2 is highly immunogenic and effective, but recent studies have indicated waning anti-SARS-CoV-2 immune responses over time. It is yet undetermined what Antibody level is correlated to immunity against developing the COVID-19 infection, Please note: A numerical value will be reported up to 2,500 U/mL. Given the difficulties with interpreting antibody tests, and that we do not yet know if a specific antibody level post-vaccination can predict protection, it would be difficult to make definitive conclusions, says Dr. Ramirez. COVID19, coronavirus disease 2019. It might say what antibody it checks (anti-S or spike antibodies for vaccination response). 2021;5(543):4549.

Some B cells respond by making antibodies straightaway. Antibodies are proteins your immune system makes to fight infection. Some tests check for anti-N and anti-S antibodies. Evaluation of antibody response after COVID-19 vaccination of healthcare workers The common goal of all vaccines developed against COVID-19, although they have been designed with different methods, is to develop an effective immunity and antibody response against SARS-CoV-2. doi: 10.1128/Spectrum.00965-21.
