COVID-19 and its SARS-CoV-2 Viral Variants have received heavy discussion lately with a big concern being that they may escape our immune response and lead to reinfection. We have discussed the decreased efficacy of monoclonal antibody therapies, the decreased effectiveness of convalescent plasma from those recovered after a COVID-19 infection, and the decreased efficacy of the AstraZeneca Vaccine. In this video, we are going to hone in on some potentially good news. Although the antibody (humoral) immune response may be less effective, this study focused on the CD8 T Cell Memory immune response. They found that the memory CD8 T cells and the viral proteins they attacked were not effected by any of the three main viral variants (UK, South African, Brazilian). Check out the video for all these details and more!
