These vaccines elicit neutralizing antibody responses directed against SARS-CoV-2 Spike protein and confer significant level of protection against SARS-CoV-2 infection. Immunization with adenovirus-vectored vaccines is known to be accompanied by the production of anti-vector antibodies, which may translate into reduced efficacy of booster or repeated rounds of revaccination. Here, we used blood samples from patients who received an adenovirus-based Gam-COVID-Vac vaccine to address the question of whether anti-vector antibodies may influence the magnitude of SARS-CoV-2-specific humoral response after booster vaccination. We observed that rAd26-based prime vaccination with Gam-COVID-Vac induced the development of Ad26-neutralizing antibodies, which persisted in circulation for at least 9 months. Our analysis further indicates that high pre-boost Ad26 neutralizing antibody titers do not appear to affect the humoral immunogenicity of the Gam-COVID-Vac boost. The titers of anti-SARS-CoV-2 RBD IgGs and antibodies, which neutralized both the wild type and the circulating variants of concern of SARS-CoV-2 such as Delta and Omicron, were independent of the pre-boost levels of Ad26-neutralizing antibodies. Thus, our results support the development of repeated immunization schedule with adenovirus-based COVID-19 vaccines.","lang":"eng"}],"publication":"npj Vaccines","file_date_updated":"2023-01-23T11:22:09Z","quality_controlled":"1","day":"15","has_accepted_license":"1","scopus_import":"1","pmid":1,"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"date_created":"2023-01-12T12:02:54Z","oa":1,"_id":"12131","license":"https://creativecommons.org/licenses/by/4.0/","ddc":["570"],"title":"Anti-Ad26 humoral immunity does not compromise SARS-COV-2 neutralizing antibody responses following Gam-COVID-Vac booster vaccination","article_type":"original","keyword":["Pharmacology (medical)","Infectious Diseases","Pharmacology","Immunology","SARS-COV-2","COVID"],"article_processing_charge":"No","language":[{"iso":"eng"}],"date_published":"2022-11-15T00:00:00Z","publication_identifier":{"issn":["2059-0105"]},"author":[{"full_name":"Byazrova, Maria G.","first_name":"Maria G.","last_name":"Byazrova"},{"full_name":"Astakhova, Ekaterina A.","last_name":"Astakhova","first_name":"Ekaterina A."},{"last_name":"Minnegalieva","first_name":"Aygul","id":"87DF77F0-1D9A-11EA-B6AE-CE443DDC885E","full_name":"Minnegalieva, Aygul"},{"first_name":"Maria M.","last_name":"Sukhova","full_name":"Sukhova, Maria M."},{"last_name":"Mikhailov","first_name":"Artem A.","full_name":"Mikhailov, Artem A."},{"full_name":"Prilipov, Alexey G.","first_name":"Alexey G.","last_name":"Prilipov"},{"last_name":"Gorchakov","first_name":"Andrey A.","full_name":"Gorchakov, Andrey A."},{"full_name":"Filatov, Alexander V.","last_name":"Filatov","first_name":"Alexander V."}],"status":"public","publisher":"Springer Nature","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8"}
