Pretty Sure that’s how Vaccines work… Expose yourself to the Virus and Build Immunity
Several new studies show that people who had even a mild coronavirus infection developed a lasting immunity to the virus.
The studies, none of which have yet been peer-reviewed, show that antibodies and immune cells known as B cells and T cells, which are able to recognize the SARS-CoV-2 virus, appear to be present months after infections have been cured.
One group of scientists “performed a longitudinal assessment of individuals recovered from mildly symptomatic COVID-19 to determine if they develop and sustain immunological memory against the virus,” their study says. “We found that recovered individuals developed SARS-CoV-2-specific IgG antibody and neutralizing plasma, as well as virus-specific memory B and T cells that not only persisted, but in some cases increased numerically over three months following symptom onset.”
“Furthermore, the SARS-CoV-2-specific memory lymphocytes exhibited characteristics associated with potent antiviral immunity: memory T cells secreted IFN-γ and expanded upon antigen re-encounter, while memory B cells expressed receptors capable of neutralizing virus when expressed as antibodies. These findings demonstrate that mild COVID-19 elicits memory lymphocytes that persist and display functional hallmarks associated with antiviral protective immunity,” the scientists wrote.
“This is exactly what you would hope for,” Marion Pepper, an immunologist at the University of Washington who co-authored the study told The New York Times. “All the pieces are there to have a totally protective immune response.”
