I just posted the following to Nextdoor about #COVID19 #vaccines and #NaturalImmunity. We'll see how long it lasts before they censor it just as they've repeatedly deleted other truthful information I've posted that is contrary to the political agenda being served:
I just saw this ad from the Michigan Department of Health and Human Services on Nextdoor that concerns me because it communicates the message that if you've had SARS-CoV-2 infection, you won't acquire natural immunity, which is false.
I note that Nextdoor's community guidelines prohibit the spread of misinformation about COVID-19 and the vaccines, so I would like to inform members of my community that there are many studies indicating that infection confers a robust and long-lasting immunity.
To address the misinformation, here are some relevant findings from the scientific literature:
"[T]he first SARS-CoV-2 vaccines are designed to induce spike-specific immunity only, as spike antibodies have protective ability....
"[T]he first SARS-CoV-2 vaccines are designed to induce spike-specific immunity only, as spike antibodies have protective ability....
"It remains to be analyzed whether vaccinations can induce a long-lasting memory T-cell response to levels similar to what can be achieved by natural infection and whether the induced Spike-specific T cells play a role in the vaccine efficacy....
"Interestingly, the scientific literature does not report any evidence of COVID-19 patients who controlled the infection only by eliciting an antibody response in the absence of detectable SARS-CoV-2 T cells,...
"...while high titers of antibodies (even neutralizing antibodies) are present in severe disease....
"Hypothetically, the ability to mount a broad T-cell response against several epitopes located in different viral proteins [other than the spike protein] might be advantageous...

"...and might avoid the selection of mutated viruses to escape CD8 T-cell recognition....
"[The] vaccines can certainly not induce the broad T-cell repertoire as seen by the natural infection, and this Spike-focused T-cell induction might not be ideal."
"[The] vaccines can certainly not induce the broad T-cell repertoire as seen by the natural infection, and this Spike-focused T-cell induction might not be ideal."
"Data now suggest that the majority of infected individuals develop robust and long-lasting T cell immunity, which has implications for the durability of immunity and future vaccine approaches....
"That the majority of CD4+ and CD8+ T cells were activated by non-S [non-spike protein] viral epitopes has implications for vaccination in populations that have experienced prior SARS-CoV-2 infections."

"Overall, we show that SARS-CoV-2 infection induces a robust antigen-specific, long-lived humoral immune response in humans."

"Many people who have been infected with SARS-CoV-2 will probably make antibodies against the virus for most of their lives. So suggest researchers who have identified long-lived antibody-producing cells in the bone marrow of people who have recovered from COVID-19.
"The study provides evidence that immunity triggered by SARS-CoV-2 infection will be extraordinarily long-lasting...."

Whoops. Forgot the screenshot of the MDHHS ad on Nextdoor. Here it is.
