Is it true that humans develop immunity to SARS-CoV-2?
Yes. Extensive immunological research confirms that humans develop durable adaptive immunity to SARS-CoV-2, characterized by long-lasting memory T cells, memory B cells, and persistent antibody responses following infection or vaccination.
Verdict: SUPPORTED · 7 sources for, 0 against · Last checked
The analysis
The claim that humans develop immunity to SARS-CoV-2 is overwhelmingly supported by multiple peer-reviewed studies documenting the generation of durable T-cell memory, memory B-cells, and long-term neutralizing antibody responses after infection and vaccination.
Evidence for · 7
Longitudinal tracking shows that mild COVID-19 infection induces persistent SARS-CoV-2-responding CD4+ and CD8+ T cell clones with memory phenotypes.
