Levels, positivity and neutralizing effect on wild type (WT) and Omicron subvariant BA.4/5 of SARS-CoV-2 specific antibodies among adults with TB. (A-C) Levels (OD value) of total antibodies against SARS-CoV-2, inhibition rates (%) of neutralizing antibodies (NAbs) against WT and Omicron subvariant BA.4/5 evaluated by SARS-CoV-2 surrogate virus neutralization test (sVNT) among adults with TB received third (booster) dose of inactivated COVID-19 vaccine, third dose (complete regime) of recombinant protein vaccine, second dose of inactivated vaccine and those unvaccinated TB patients. HCs were age-, gender- and vaccination time-matched with TB patients who have inoculated second and third (booster) dose of inactivated vaccine. Antibody positivity was shown each panel below the figures where positive rate was presented as dark red for adults with TB and as dark blue for HCs. Optical density (OD) values above 0.19 were regarded as positive for total antibodies against SARS-CoV-2. Inhibition rate above 30% were regarded as positive. (D) Inhibition ability of NAbs against BA.4/5 (purple bar) and against WT (dark blue bar) among adults with TB and HCs. Seropositivity of NAbs against BA.4/5 remained below positive threshold (30%) at all sampling time after vaccination.
