BIRMINGHAM, UK: To fill a research gap, researchers have recently examined whether dental professionals are, in fact, at an increased risk of becoming infected with SARS-CoV-2 in the workplace, as has often been hypothesised. They found that close contact with patients put dental professionals at a higher risk of developing COVID-19 during the first wave of the pandemic and that a large number of dental professionals had SARS-CoV-2 antibodies in their blood.
Vaccine development against SARS-CoV-2 would be greatly facilitated by the identification of immunological parameters that correlate with protection in humans. However, to date, most studies on protective immunity have only been performed in animal models and correlates of protection have not been established in humans. This study provides the first direct evidence that SARS-CoV-2 neutralizing antibodies protect against SARS-CoV-2 re-infection in humans.
