Vaccines pave the way out of the SARS-CoV-2 pandemic. We have developed a virus-like particle (VLP)-based vaccine using the baculovirus-insect cell expression system, a robust production platform known for its scalability, low cost, and safety. Baculoviruses were constructed encoding SARS-CoV-2 spike proteins: full-length S, stabilized secreted S, or the S1 domain. This two-component nanoparticle vaccine can now be further developed to help alleviate the burden of COVID-19.
