In the human adaptive immune system, we have two different types of responses to infections: B cell responses (responsible for producing antibodies), and T cell responses. Low antibody levels might still offer useful protection, while normal antibody levels do not guarantee complete protection. Because of that, it can be challenging to compare neutralizing antibody tests between studies and labs. 10.1016/j.bbrc.2021.01.073 2022 Aug 1;13:966098. doi: 10.3389/fimmu.2022.966098.
