Natural Immunity Really Lasts According to New Data
Data really does destroy delusion
A new report by Johns Hopkins researchers characterized natural immunity and long-term durability among unvaccinated individuals using anti–spike antibodies, the first line of defense against SARS-CoV. The results are spectacular as shown in the graph below. It shows that people with natural immunity have the same level of antibodies no matter when they were infected.
The most basic finding is that unvaccinated people who have recovered from COVID have similar spike protein antibody levels whether they were infected 20 days or 20 months ago.
Anti-spike protein antibodies following COVID infection and recovery seem to persist indefinitely in unvaccinated people. People tested 20 months after coronavirus infection had slightly higher levels of antibodies on average than those just after infection.
Importantly, spike protein antibodies in uninfected people who have received mRNA vaccines are known to decline at a rate of up to 40 percent a month.
Moreover, nearly all of the non-vaccinated people also had antibodies to another part of the Sars-Cov-2 virus, the nucleocapsid (think of it as the body of the virus molecule) not just the spike protein. People who are vaccinated do not have those nucleocapsid antibodies.
This study proves that people who have recovered from Covid have far better protection from future infection than vaccinated people.
In this cross-sectional study of unvaccinated US adults, antibodies were detected in 99% of individuals who reported a positive COVID-19 test result, in 55% who believed they had COVID-19 but were never tested, and in 11% who believed they had never had COVID-19 infection.
