(The T-cells) can attack the internal proteins of each of these related viruses - theold - 11-01-2022
"The fact that (the T-cells) can attack the internal proteins of each of these related viruses [COVID-19 variants] means that they give what's called a broad cross-protection," Lalvani told CBS News.
"That's in sharp contrast to the surface spike protein, which is the target of antibodies induced by vaccines. And clearly, SARS-CoV-2 is under huge, intense pressure in the global population because most people now have these antibodies, whether induced by vaccination or infection, so the virus is trying naturally to evade that immunity through mutation, and that's why Omicron has such a high number of mutations in the spike protein. But the internal proteins are relatively unchanged."
