BACKGROUND



Challenge of COVID-19 vaccine discovery & development: to meet accumulated mutating of SARS-CoV-2 and a long-term viral genome transcrption

COVID-19 (Coronavirus Disease 2019) is novel viral pneumonia caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2, also called 2019nCoV). The world is in midst of the COVID-19 pandemic. Effective vaccines are needed to halt the spread of the SARS-CoV-2 pandemic. Based on the data from WTO, there are 52 COVID-19 vaccines in clinical stage (Supplementary Table 1.) and 162 COVID-19 vaccine candidates in pre-clinical stage (Supplementary Table 2.) 2 mRNA vaccines, the BNT162b2 from Pfizer&BioNTech and the mRNA-1273 from Moderna, have recently been issued the emergency use authorization (EUA) by the U.S. Food and Drug Administration (FDA) for the prevention of COVID-19 in individuals 16 years of age and older.

The efficacy and safety of COVID-19 vaccine candidates need carefully investigated, from pre-clinical, clinal stage to a long time after BLA. There are 2 important items here:

Firstly, the coronavirus is kept accumulated mutating. The most important mutation occurs in SARS-CoV-2 (2019nCoV) Spike protein (SARS-CoV-2 S protein). The SARS-CoV-2 (2019nCoV) Spike mediates binding and entry into host cells and is a major target of neutralizing antibodies. Most of the COVID-19 vaccines focus on spike protein1,4-6.

Different SARS-CoV-2 lineages with diverse Spike protein mutant variants may yield a heavy impact on the course of the pandemic2-3. The United Kingdom (UK) has faced a rapid increase in COVID-19 cases caused by a novel SARS-COV-2 (2019nCOV) lineage, the B.1.1.7 lineage, which carries a larger than a usual number of coronavirus genetic changes7-8, particularly in the SARS-CoV-2 spike protein(Table 1)7.

Secondly, SARS-CoV-2 was reported to integrate into the genome, which means a stable long-term expression of transcript products of SARS-CoV-2 9.

In conclusion, the Efficacy of COVID-19 vaccines and neutralized antibodies need long-term tracking, which mainly focuses on the novel spike protein mutation occurring in the new lineage variant of SARS-CoV2. The efficacy evaluation solution and tools of COVID-19 vaccines and neutralized antibodies need continually updated.

New variant of SARS-COV-2 (2019nCOV) B.1.1.7 lineage spreaded in UK

The world is in midst of the COVID-19 pandemic. Recently a novel SARS-COV-2 (2019nCOV) lineage, the B.1.1.7 lineage, with serials of site mutation, shows stronger infection ability in the UK. The SARS-COV-2 B.1.1.7 lineage carries a larger than a usual number of coronavirus genetic changes.

4. About COVID-19 Pandemic and SARS-CoV-2 Vaccine

Coronavirus Disease 2019 (COVID-19) is a novel viral pneumonia caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). First discovered in Wuhan, a city in Hubei province of China, COVID-19 has already broken out throughout the world and posed a great threat to the public health, especially in Europe and North America now. Additionally, person-to-person transmission of COVID-19 disease is reported to be extremely rapid [158-160]. To date, more than one million cases were infected with COVID-19 and over 55,000 deaths occurred. Therefore, it is really urgent and noteworthy to develop the vaccines specific to COVID-19/SARS-CoV-2.

Belonging to the Betacoronavirus genus family, SARS-CoV-2 is 60~200nm in diameter and encapsidates a large positive-sense, single-stranded RNA virus (26-32kb) with many spikes on the virus capsid (Fig. 17A). The RNA genome of SARS-CoV-2 encodes several accessory proteins and structural proteins, such as nucleocapsid (N) protein, envelope (E) protein, membrane (M) protein, and spike (S) protein (Fig. 10B). Although the detailed mechanism of SARS-CoV-2 infection has not been clearly illuminated, several studies demonstrated that SARS-CoV-2 enters human cells via utilizing spike (S) protein to bind to the angiotensin converting enzyme (ACE2) on the surface of target cell [161, 162]. Picture loading failed.

M: membrane. N: nucleocapsid. HR1: heptad repeat 1. HR2: heptad repeat 2. SP: signal peptide. NTD: N-terminal domain. RBD: receptor binding domain. S: spike. S1: subunit 1. S2: subunit 2. TM: transmembrane domain.

Since the genome sequences of SARS-CoV were discovered and reported (https://www.gisaid.org/CoV2020/), a large number of pharmaceutical enterprises and research organizations are sparing all efforts to the vaccine development. Different companies utilize different targets and antigen epitopes. Some of the advances are listed in the following Table 10 (from WHO), and most of them focus on viral vector-based vaccines (replicating or non-replicating viral vector-based vaccines), recombinant protein (Spike), and nucleic acid-based vaccines. To date, two COVID-19 vaccines have entered Phase I clinical testing to assess the safety and potency of vaccines. One is mRNA-1273, was developed by Moderna Therapeutics, encoding a prefusion-stabilized form of Spike (S) protein [163] (https://www.nature.com/articles/d41587-020-00005-z). Another vaccine is recombinant protein of SARS-CoV-2 antigen, developed by Chinese Academy of Military Sciences, Institute of Military Medicine. It was predicted that these vaccines can be applied in clinics in a large scale as early as 2021 if they can successfully pass the clinical testing. Although there is a long way for theses vaccines to be applied for prevention and therapy of COVID-19, they indeed bring great hope and light to people all over the world.
