Pfizer and Moderna vaccines might produce immunity against COVID-19 lasting for years
According to a new study publicized in the journal Nature, the Pfizer and Moderna vaccines for COVID-19 may provide a stronger, prolonged immune system response than previously known, protecting against COVID-19 for years.
The study showed promising results, demonstrating how durable the immunity of the vaccines is. Researchers did not test the Johnson & Johnson vaccine, with speculation that the immune response may be less durable.
In the findings, researchers showed that immunity might last for years and even a lifetime, preventing infections even among variants.
From the study: “We examined antigen-specific B cell responses in peripheral blood (n=41) and draining lymph nodes (LNs) in 14 individuals who received two doses of BNT162b2, an mRNA-based vaccine encoding full-length SARS-CoV-2 spike (S) gene.”
“Our studies demonstrate that SARS-CoV-2 mRNA-based vaccination of humans induces a persistent GC B cell response, enabling the generation of robust humoral immunity.”
The study was authored by a coalition of researchers across America.
