A new study has been published details that our bodies may already have what it takes to provide a level of coronavirus immunity.
According to a new study published in Nature Reviews: Immunology, our bodies could already contain certain cells that would know how to fight off a COVID-19 infection. These cells mentioned in the study are called T cells and initiate an immune reaction to SARS-CoV-2. Researchers suggest that some of us already have these T cells present in our bodies from previous battles with common cold coronaviruses.
The researchers concluded through their evidence that there's a pre-existing immune reactivity in the general population to SARS-CoV-2 and that this level of immunity might be to immunity against common cold coronaviruses. Additionally, this certain immunity level may also have implications for COVID-19 disease severity, vaccines, and herd immunity. The study does mention that this has not been officially proven and that more research is still needed to be done.
