Cellular or antibody responses is measured in the most studies of immunity to SARS-CoV-2 (COVID-19).1 Nevertheless, if ever SARS-CoV-2 (COVID-19) present in the plasma, the infectious virus is rarely infects the nasal and conjunctival mucosal surfaces.1 In COVID-19-infected-unvaccinated and unvaccinated-COVID-19-uninfected individuals, the levels of nasal and salivary anti-spike antibody correlated significantly with plasma antibody.1,2 The reported mean correlations for titers in plasma and saliva for IgG and IgA were moderate (p = 0.55; 95 % CI : 0.38-9.73) and weak (p = 0.28; 95 % CI : 0.12-0.44), respectively.2 A previous systematic review demonstrated that previous-COVID-19-infected-vaccinated individuals demonstrated boosting anti-spike antibody levels in the nose or saliva less than in plasma.1
In conclusion, potent immune response induced by COVID-19 mucosal vaccines at the sites of SARS-CoV-2 (COVID-19) infection is urgently needed. Persistent mucosal antibody may not indicate persistent increase of SARS-CoV-2 plasma antibody levels.
