We investigated the neutralisation of isolated virus by antibodies induced by earlier infection or vaccination. The neutralisation titres for BA.2.86 were comparable to those for XBB.1 and EG.5.1, by antibodies induced by XBB.1.5 or BA.4/5 breakthrough infection or BA.4/5 vaccination.xref:EuropePMC:PMC10819014xref:EuropePMC:PMC11981944xref:EuropePMC:PMC12262575ENACOVID19, SARS Coronavirus 2, SARS-CoV-2 Viruses, β-CoVs, 2019 Novel, 2019 Novel Coronavirus, betacoronavirus, β-CoV, Viruses, beta-CoV, COVID-19 Viruses, Coronavirus Disease 2019 Virus, COVID-19, Wuhan Seafood Market Pneumonia Virus, 2019 Novel Coronaviruses., SARS-CoV-2, severe acute respiratory syndrome coronavirus 2, 2019 novel coronavirus, Coronavirus 2, Wuhan, SARS CoV 2 Virus, beta-CoVs, COVID19 Virus, SARS-coronavirus 2, COVID-19 Virus, COVID19 Viruses, Severe Acute Respiratory Syndrome Coronavirus 2, SARS, SARS-CoV-2 Virus, Novel Coronavirus, Virus, 2019, Coronavirus, COVID 19 Virus, β-coronavirus, 2019-nCoV, Wuhan CoronavirusCOVID19, SARS-CoV-2 Viruses, 2019 Novel Coronavirus, β-CoV, beta-CoV, COVID-19 Viruses, COVID-19, SARS-CoV-2, Infestations and Infections, 2019 novel coronavirus, Coronavirus 2, Immunizations, SARS CoV 2 Virus, antibodies, COVID19 Virus, Active Immunization, Immunization, active immunization, COVID19 Viruses, Severe Acute Respiratory Syndrome Coronavirus 2, SARS, SARS-CoV-2 Virus, Novel Coronavirus, Virus, Infection, Active., Active, Coronavirus, β-coronavirus, 2019-nCoV, 2019 Novel Coronaviruses, SARS Coronavirus 2, β-CoVs, 2019 Novel, betacoronavirus, Viruses, Coronavirus Disease 2019 Virus, Wuhan Seafood Market Pneumonia Virus, severe acute respiratory syndrome coronavirus 2, Infection and Infestation, Wuhan, Active Immunizations, beta-CoVs, clinical infection, SARS-coronavirus 2, COVID-19 Virus, Infestation and Infection, 2019, COVID 19 Virus, Infections and Infestations, Vaccinations, Wuhan CoronavirusfalseNeutralisation of SARS-CoV-2 Omicron subvariants BA.2.86 and EG.5.1 by antibodies induced by earlier infection or vaccinationSARS-CoV-2 BA.2.86 and EG.5.1 Neutralisation2023-10-162023-10-16PRJEB67449
