A live attenuated virus-based intranasal COVID-19 vaccine provides rapid,prolonged,and broad protection against SARS-CoV-2
文献摘要:
Remarkable progress has been made in developing intramuscular vaccines against severe acute respira-tory syndrome coronavirus 2(SARS-CoV-2);however,they are limited with respect to eliciting local immunity in the respiratory tract,which is the primary infection site for SARS-CoV-2.To overcome the limitations of intramuscular vaccines,we constructed a nasal vaccine candidate based on an influenza vector by inserting a gene encoding the receptor-binding domain(RBD)of the spike protein of SARS-CoV-2,named CA4-dNS1-nCoV-RBD(dNS1-RBD).A preclinical study showed that in hamsters challenged 1 d after single-dose vaccination or 9 months after booster vaccination,dNS1-RBD largely mitigated lung pathology,with no loss of body weight.Moreover,such cellular immunity is relatively unimpaired for the most concerning SARS-CoV-2 variants,especially for the latest Omicron variant.In addition,this vaccine also provides cross-protection against H1N1 and H5N1 influenza viruses.The protective immune mech-anism of dNS1-RBD could be attributed to the innate immune response in the nasal epithelium,local RBD-specific T cell response in the lung,and RBD-specific IgA and IgG response.Thus,this study demon-strates that the intranasally delivered dNS1-RBD vaccine candidate may offer an important addition to the fight against the ongoing coronavirus disease 2019 pandemic and influenza infection,compensating limitations of current intramuscular vaccines.
