The problem is that to the extent that messaging about immunology was provided by public health authorities to the general public or used to develop policy, it was almost always about antibodies as a correlate of protection, lack of antibodies as evidence that SARS-CoV-2 was novel and not yet endemic (providing justifications for lockdowns/the CARES Act/EUAs and mass vaccinations including children), or about falling antibody titers as a justification for booster shots. There was hardly even any mention of very basic things like Vitamin C, D and Zinc, let alone T cell immunity. T cell studies exist in the literature, of course, but our understanding of T cells and Natural Killer cells seems to have been allowed to contribute very little little to the public health response in many countries in contrast to patented vaccine candidates and antivirals.
