Reduced ability to neutralize the Omicron variant among adults after infection and complete vaccination with BNT162b2, ChAdOx1, or CoronaVac and heterologous boosting
Résumé fourni par la source
COVID-19 vaccines have dramatically reduced rates of severe infection requiring hospitalization. However, SARS-CoV-2 variants have reduced vaccine effectiveness at preventing any symptomatic infection. This real-world study analyzed binding and neutralizing antibodies generated after complete vaccination and boosting across three vaccine platforms. Binding antibodies decayed most slowly in people under 60 with hybrid immunity. Neutralizing antibodies against Omicron BA.1 were reduced compared to other variants. The anamnestic anti-spike IgG response to the first boost was more pronounced than after the second boost. Monitoring of the effects of SARS-CoV-2 mutations on disease severity and the effectiveness of therapeutics is warranted.
