Probiotics-mediated COVID-19 Vaccine solution

The novel coronavirus SARS-CoV-2/2019-nCoV is an enveloped, non-segmented, positive sense RNA virus that has four main structural proteins [Spike (S)-Envelope (E)-Membrane (M)-Nucleocapsid (N)]. The spike (S) protein, a main target for neutralization antibody, is crucial for determining host tropism and transmission capacity by attraction with angiotensin-converting enzyme 2 (ACE2). Generally, spike glycoprotein is functionally cleaved by the host cell furin-like protease into S1 domain and S2 domain. The S1 domain is responsible for receptor binding while S2 domain functions to mediate virus fusion in transmitting host cells.

Vaccine is a biological preparation that is recognized worldwide as one of the most effective ways for combating infectious diseases. Recombinant protein-based vaccines ang probiotics-based oral vaccines are new approaches to prevent COVID-19 caused by SARS CoV2 and other coronaviruses of pandemic potential. Furthermore, novel strategies based on food grade vaccine formulations have been demonstrated to trigger both a systemic and mucosal immune response.
