MERS CoV vaccines for coronavirus

 

Middle East respiratory syndrome-related coronavirus, or EMC/2012, is a species of coronavirus which infects humans, bats, and camels.

1 . Novavax’s MERS coronavirus vaccine candidate

Maryland based Novavax developed a novel Middle East Respiratory Syndrome (MERS) coronavirus vaccine candidate in 2013, post the identification of the first MERS coronavirus ((MERS-CoV) in Saudi Arabia in 2012. It is a crucial target for coronavirus vaccine development by the Coalition for Epidemic Preparedness Innovations (CEPI) and is a priority disease for the World Health Organisation (WHO).
The candidate is designed to primarily bind to the major surface S-protein and developed using the company’s recombinant nanoparticle vaccine technology. Tested along with the Novavax’s proprietary adjuvant Matrix-M™, it inhibited infection by inducing immune responses in the laboratory studies.
Novavax has received $4m in funding from CEPI to advance the development of the vaccine. The company has produced several nanoparticle vaccine candidates for testing in animal models and aims to carry out human trials in 2020.
The MERS coronavirus is related to the severe acute respiratory syndrome (SARS) coronavirus, for which the company had previously developed a recombinant nanoparticle vaccine candidate.

2 . Inovio Pharma’s INO-4700

Inovio Pharma haven’t disappointed us in this segment also. It’s investigational DNA immunotherapy, INO-4700 (GLS-5300) is being developed in partnership with GeneOne Life Science. It is delivered as vaccine intramuscularly, using the Cellectra® delivery device.
The company has received a $5m grant from the Bill and Mellinda Gates foundation to accelerate the development of the Cellectra® delivery device.
The vaccine was well-tolerated and demonstrated high immune responses against the MERS-CoV in 94% of patients in the early-stage clinical trial in July 2019.
It also generated broad-based T cell responses in 88% of the subjects.
While most of the world around us is still in a panic mode. These pharmaceutical companies along with many others (who are in the process of filing patents and did not find a mention here) in conjunction with multi-lateral research and funding agencies are in pursuit of a exponential disruption to these global pandemic of Covid-19. However India with an expected $55 Billion Pharmaceutical Industry and Government’s “Pharma Vision 2020” of turning India in to a leading exporter of Pharmaceuticals, lags behind in breaking the R&D ceiling of Covid-19 vaccine development. With a ray of hope for an abundant and healthy future, we will continue with our discussion on the drugs of choice for the CoVid 19 in our next series.
