This manuscript describes an extended work on the Newcastle disease virus (NDV)-based vaccine focusing on multivalent formulations of NDV vectors expressing different prefusion-stabilized versions of the spike proteins of different SARS-CoV-2 variants of concern (VOC). We demonstrate here that this low-cost NDV platform can be easily adapted to construct vaccines against SARS-CoV-2 variants.
