Severe respiratory problem coronavirus 2 (SARS-CoV-2) has fastly spread within the human population. In spite of the fact, SARS-CoV-2 is a novel coronavirus, most humans had been early exposed to other antigenically different common seasonal human coronaviruses (hCoVs) earlier than the COVID-19 pandemic. Few scientists have suggested that people might be protected from SARS-CoV-2 infection if they have lately been caught by a seasonal coronavirus.
In Philadelphia, Scott Hensley at the University of Pennsylvania and his colleagues examined blood samples recovered before the pandemic from around 500 people. After that, they longitudinally measured hCoV and SARS-CoV-2 antibodies in the serum of hospitalized COVID-19 patients. Their studies indicate that most people already gave hCoV-reactive antibodies before the COVID-19 pandemic. They found that ∼23% of these people already have antibodies that could recognize SARS-CoV-2, which apparently developed in response to infection with a common-cold coronavirus.
Half of the people apparently catch SARS-CoV-2. People who became infected by this and those who didn’t had same level of antibodies recognizing SARS-CoV-2. This suggests that neither those antibodies nor those that recognize OC43 offer any protection against infection.
