Covid infection, vax boosts T cell immune responses against Omicron

T cell responses are still robust against the variant in most individuals with prior SARS-CoV-2 infection or vaccination, despite low antibody responses, finds a study.This also provides protection against severe disease, said researchers at .

Structure-guided T cell vaccine design could offer broad protection SARS-CoV-2 variants

Structure-guided T cell vaccine design could offer broad protection SARS-CoV-2 variants Gaurav Gaiha, MD, DPhil, a member of the Ragon Institute of MGH, MIT and Harvard, studies HIV, one of the fastest-mutating viruses known to humankind. But HIV s ability to mutate isn t unique among RNA viruses most viruses develop mutations, or changes in their genetic code, over time. If a virus is disease-causing, the right mutation can allow the virus to escape the immune response by changing the viral pieces the immune system uses to recognize the virus as a threat, pieces scientists call epitopes. To combat HIV s high rate of mutation, Gaiha and Elizabeth Rossin, MD, PhD, a Retina Fellow at Massachusetts Eye and Ear, a member of Mass General Brigham, developed an approach known as structure-based network analysis. With this, they can identify viral pieces that are constrained, or restricted, from mutation. Changes in mutationally constrained epitopes are rare, as they can cause the virus
