Abstract Current available vaccines for COVID-19 are effective in reducing severe diseases and deaths caused by SARS-CoV-2 infection but less optimal preventing infection. Next-generation which able to induce mucosal immunity the upper respiratory prevent or reduce infections highly transmissible variants of urgently needed. We have developed an intranasal vaccine candidate based on a live attenuated influenza virus (LAIV) with deleted NS1 gene that encodes cell surface expression...
Abstract Memory T cells play a key role in immune protection against cancer. Vaccine-induced tissue-resident memory (TRM) the lung have been shown to protect metastasis. Identifying source of TRM can help improve strategies, preventing tumor Here, we found that prime-boost vaccination approach using intramuscular DNA vaccine priming, followed by intranasal live-attenuated influenza-vectored (LAIV) boosting induced higher frequencies CD8+ compared with other regimens. cells, but not...

Abstract We have developed an intranasal vaccine candidate based on a live attenuated influenza virus (LAIV) with deleted NS1 gene that encodes cell surface expression of the receptor-binding-domain (RBD) SARS-CoV-2 spike protein, designated DelNS1-RBD4N-DAF. Immune responses and protection against challenge following administration DelNS1-RBD4N-DAF vaccines were analyzed in mice compared intramuscular injection BioNTech BNT162b2 mRNA hamsters. LAIVs induced high levels neutralizing...
