Seems pretty convincing to me, but of course MSM is silent: "Substantial data now demonstrate the presence of preexisting T-cell immunity to SARS-CoV-2 in blood donors either prior to the COVID-19 pandemic or more recently among those without infection."
Declines in SARSCoV2 IgG neutralizing Abs raise concerns of susceptibility to reinfection. But acute Ab levels always decline post-infection, and Ab recall responses come from a pool of long-lived memory B cells
Two key paths to #COVID19 adaptive immunity—antibodies to the spike protein, and T cell immunity—are being surveyed and vaccines exploiting this knowledge are in rapid development
Nice, short and reasonably accessible review on "#COVID19 and the Path to Immunity". Conclusion: "SARS-COV-2 may well follow the path of previous coronaviruses and become endemic in the population as another common cold virus."
JAMA goes “far-right conspiracy theory” on T-cells. “Substantial data now demonstrate the presence of preexisting T-cell immunity to SARS-CoV-2 in blood donors either prior to the COVID-19 pandemic or more recently among those without infection.”
The path to adaptive immunity. Very good summary of recent studies on the immune response, acutely and memory (on demand) by and

COVID-19 and the Path to Immunity | Infectious Diseases | JAMA | A nice summary useful to an ID epidemiologist! “Thus, in the few “short” months since recognition of this virus, 2 keys paths to COVID-19 adaptive immunity are being unraveled” #COVID19
Knowledge on immunity to SARS-CoV-2 is progressing quickly but we still get neither data nor stats on serology. Les connaissances sur l’immunité au virus progressent rapidement mais nous n’avons toujours pas de données ni de statistiques sérologiques.
