It seems natural immunity after getting it might be very robust and last years. If that happens we will lose covid as a tool of oppression and economic destruction.
This study report must be suppressed because it could reduce panic. We can’t have that.

Notably, memory B cells specific for the Spike protein or RBD were detected in almost all COVID-19 cases, with no apparent half-life at 5 to 8 months post-infection. Other studies of RBD memory B cells are reporting similar findings (50, 60). B cell memory to some other infections has been observed to be long-lived, including 60+ years after smallpox vaccination (61), or 90+ years after infection with influenza (62). The memory T cell half-lives observed over 6+ months PSO in this cohort (~125-225 days for CD8+ and ~94-153 days for CD4+ T cells) were comparable to the 123 days t1/2 observed for memory CD8+ T cells after yellow fever immunization (56). SARS-CoV-2 T cell memory at 6 months has also now been reported in another study (63). Notably, the durability of a fraction of the yellow fever virus-specific memory CD8+ T cells possessed an estimated t1/2 of 485 days by deuterium labeling (56). Using different approaches, the long-term durability of memory CD4+ T cells to smallpox, over a period of many years, was an estimated t1/2 of ~10 years (61, 64), which is also consistent with recent detection of SARS-CoV-T cells 17 years after the initial infection (65). These data suggest that T cell memory might reach a more stable plateau, or slower decay phase, beyond the first 8 months post-infection.
