In those who have recovered from COVID-19, and have a well documented clinical case, 99% have neutralizing antibodies.
Prevalence and Durability of SARS-CoV-2 Antibodies Among Unvaccinated US Adults by History of COVID-19, published February 2022.
Precision Vaccinations (PVax) reports: “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.” Immunity from survived infection is limited to 250 days because that is how long the virus has been ‘around’.
Board-certified clinical pathologist, Dr. Ryan Cole, suggests mandating vaccines for the COVID recovered makes no sense given the durable, natural immunity this group possesses.
Foundation for Economic Education published the details on Comparing SARS-CoV-2 natural immunity to vaccine-induced immunity: reinfections versus breakthrough infections, posted in preprint August 2021.:
“A newly published medical study found that infection from COVID-19 confers considerably longer-lasting and stronger protection against the Delta variant of the virus than vaccines.
“The natural immune protection that develops after a SARS-CoV-2 infection offers considerably more of a shield against the Delta variant of the pandemic coronavirus than two doses of the Pfizer-BioNTech vaccine, according to a large Israeli study that some scientists wish came with a ‘Don’t try this at home’ label,” Science reported Thursday. “The newly released data show people who once had a SARS-CoV-2 infection were much less likely than vaccinated people to get Delta, develop symptoms from it, or become hospitalized with serious COVID-19.”
Put another way, vaccinated individuals were 27 times more likely to get a symptomatic COVID infection than those with natural immunity from COVID.”
