A new study in Israel compared the protection provided by vaccine-induced immunity with natural immunity after a previous COVID-19 infection and showed that the latter provides much better protection against infection, symptomatic illness and hospitalization.
Natural immunity provides much longer protection
Directly comparing 16,215 previously COVID-19-infected people with 16,215 fully vaccinated people, 10 physicians (Gazit et al., 2021) tentatively report (preprint) that fully vaccinated people are (a) 13 times more likely to get COVID-19 infection, (b) 27 times more likely to have symptomatic illness, and (c) 8 times more likely to be hospitalized than unvaccinated people with prior COVID infection (natural immunity).
“This study demonstrated that natural immunity provides longer-lasting and stronger protection against infection, symptomatic illness, and hospitalization caused by the delta variant of SARS-CoV-2 compared with immunity caused by two doses of BNT162b2 vaccine.”
Other studies (Dan et al., 2021, Turner et al., 2021) have also shown that natural immunity obtained after a previous infection provides long-lasting, even “lifelong” protection against reinfection, or that “individuals who have had SARS-CoV-2 infection are unlikely to benefit from COVID-19 vaccination” (Shrestha et al., 2021).
Vaccine efficacy decreases by 56% in just 70 days
A new study published in The Lancet reports an initial spike in antibody protection in those who received a second dose of the Pfizer vaccine.
Unfortunately, just a few weeks after the last vaccination, the effectiveness of the vaccine begins to decline dramatically. In just 2.5 months, antibody levels for the Pfizer vaccine dropped by 56%.
Exponential “decline” in vaccine effectiveness of up to 40% in the month after the last vaccination
Another new study highlights the precipitous drop in antibody protection almost immediately after the second vaccination.
While people with natural immunity after a previous COVID-19 infection (convalescents) lose <5% of antibody protection in the month after COVID-19 infection, vaccinated people alone lose up to 40% of immunity protection each month after the last vaccination.
At this rate, the artificial immunity provided by vaccines wanes within a few months.
