Here we demonstrate that vaccinated subjects made CD4 + T cell responses after one and two doses of NVX-CoV2373, and a subset of individuals made CD8 + T cell responses. Characterization of the vaccine-elicited CD8 + T cells demonstrated IFN γ production. Characterization of the vaccine-elicited CD4 + T cells revealed both circulating T follicular helper cells (cT FH ) and T H 1 cells (IFN γ , TNFα, and IL-2) were detectable within 7 days of the primary immunization. Spike-specific CD4 + T cells were correlated with the magnitude of the later SARS-CoV-2 neutralizing antibody titers, indicating that robust generation of CD4 + T cells, capable of supporting humoral immune responses, may be a key characteristic of NVX-CoV2373 which utilizes Matrix-M™ adjuvant.","journal":"bioRxiv (Cold Spring Harbor Laboratory)","year":2022,"id":303119,"datarank":0.10397207708399181,"base_score":0.6931471805599453,"endowment":0.6931471805599453,"self_citation_contribution":0.10397207708399181,"citation_network_contribution":0.0,"self_endowment_contribution":0.10397207708399181,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":1,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9522,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":104939,"name":"Christina Kim","orcid":"0000-0003-4404-215X","position":1,"is_corresponding":false},{"id":103768,"name":"José Mateus","orcid":"0000-0002-1402-3452","position":2,"is_corresponding":false},{"id":860188,"name":"Joyce S.
