Natural Immunity After COVID-19 Found Durable and Robust

Ending the COVID-19 pandemic will require long-lived immunity to SARS-CoV-2, wrote researchers who published a new study in the journal Cell on July 14, 2021.
‘To end the COVID-19 pandemic, it is critical to know how long immunity against SARS-CoV-2 will persist after infection and whether it will be sufficient to prevent new infections and severe disease in years to come, continued this study,’ which is excerpted below.
‘Identifying, in-depth, the adaptive immune components leading to recovery and modeling the trends of each response was enabled by the longitudinal sampling of a large number of COVID-19 patients.'
This new study shows that most convalescent COVID-19 patients mount durable antibodies, B cells, and T cells specific for SARS-CoV-2 up to 250 days. The kinetics of these responses provide an early indication for a favorable course ahead to achieve long-lived immunity.
Because the cohort will be followed for 2–3 more years, they can build on these results to define the progression to long-lived immunity against this novel human coronavirus, which can guide rational responses when future virus outbreaks occur.
The hallmark of the initial immune defense against SARS-CoV-2 is the emergence of antibodies recognizing the SARS-CoV-2 spike protein, including the RBD and NTD components of the S1 subunit, during the early phase of viral replication.
These antibodies are likely secreted from plasmablasts rapidly generated from B cells activated upon their first encounter with the pathogen spike antigen.
The swift rise over the first month of infection, followed by a fast decline of the circulating spike IgG and IgA antibodies, is a consistent finding and likely explained by the disappearance of the short-lived plasmablasts.
These events occur even sooner for the spike IgM and nucleocapsid antibodies. . . .

Here is yet another study showing that naturally developed immunity from successfully fighting off an infection is long-lasting. It is also a study that the 'vax & mask' fascists continue to ignore. In addition, the study shows that there is cross-immunity between SARS-1 and SARS-2. This could explain why I haven't gotten it since I was exposed to SARS-1 while in China in 2005.
