The race to create and distribute efficient COVID-19 vaccines continues. Big pharmaceutical corporations are producing promising vaccines and preliminary distribution is underway, nonetheless, this isn’t with out quite a few issues or logistical hurdles. What you do not hear a lot about is the smaller biotech corporations working onerous behind the scenes to develop different medicines which have huge potential in preventing the novel coronavirus and way more.
Concerns with current big pharma options
The COVID-19 pandemic is quickly altering vaccine know-how, with revolutionary approaches which are transferring away from using dwell viruses in direction of genetic-based approaches utilizing RNA and DNA vaccines.
Reasonably than injecting a weakened type of a virus or bacteria into the physique, like with the flu vaccine, DNA and RNA vaccines use a part of the virus’ personal genes to create antigens that stimulate an immune response. So, when somebody who was handled with the vaccine will get exposed to the virus in a while, their immune system will be capable to battle it off extra simply and cut back their danger for critical sickness.
Whereas it is vital to provide a protected, efficient COVID-19 vaccine, the main candidates are RNA vaccines, which regardless of promising results, do have a number of drawbacks. RNA could be very simply destroyed because of the physique’s pure enzymes and chemical reactions which is able to break the RNA aside. In consequence, these vaccines should be manufactured, shipped and saved underneath very particular and intensely cold conditions in an effort to attempt to sluggish or stop that breakdown of RNA.
These stability and manufacturing points can result in restricted manufacturing capabilities, leaving governments and communities preventing for available provides. Distribution and storage is advanced, with one choice requiring greater than -70 levels Celsius refrigeration. Provide chain points could also be an ongoing situation.
Small biotech with huge concepts and the potential to avoid wasting lives
Whereas leading pharmaceutical corporations are spearheading the battle towards COVID-19, it is essential to think about the potential applied sciences that smaller organizations are researching. A kind of corporations is Orbis Well being Options, a South Carolina-based biotech utilizing its deep most cancers analysis expertise and established vaccine technology to create a new strategy to preventing COVID-19 – a DNA vaccine that addresses the shortcomings of the present forerunners and with the ability to fight future viruses and organic threats.
Based mostly on the research and science of Thomas E. Wagner, Ph.D., the corporate’s founder and chief scientific officer, the potential COVID-19 vaccine makes use of a blueprint primarily based on Orbis’ success in treating cancer by means of personalised vaccines. Along with optimistic knowledge from its Part IIb cancer medical trial, proof-of-concept research have demonstrated that Orbis’ vaccine know-how platform has a variety of chance, from addressing agriculture and veterinary functions to preventing future pandemics and organic threats.
“We’ve got developed a really successful vaccine towards cancer, which is probably the most difficult problem for the immune system,” says Wagner. “Now we have shifted our science and know-how to battle the current COVID-19 pandemic and what we’re seeing is extremely hopeful.”
The science for the brand new vaccine relies on cancer vaccine know-how that delivers foreign substances (antigens) to assist the immune system to recognize an invader and set off an immune response. In most cancers remedy, that is created with antigens from a patients’ personal tumor. For COVID-19, Orbis scientists have created an artificial duplicate of parts of the DNA code of the virus specializing in the spike proteins, which is the exterior a part of the virus that penetrates a healthy cell. The vaccine contains this info in an effort to set off a response and assist educate the immune system easy methods to battle the foreign invader and eliminate the virus.
Neutralizing antibodies in 100% of trial contributors
The excellent news: Early knowledge exhibits promise. Outcomes of a medical trial evaluating 20 wholesome volunteers demonstrated that one inoculation with the vaccine led to 100% of contributors expressing neutralizing antibodies towards the virus, that means the vaccine is profitable in triggering that vital immune response to COVID-19.
The Orbis COVID-19 vaccine would not use any a part of the virus itself, solely the DNA encoding the spike protein. Because of this, it’s believed to be a protected choice with few side effects. What’s extra, there is not any want for low-temperature storage and it is extremely scalable, so it might be simpler to rapidly get sufficient vaccine worldwide, particularly to those that want it most.
“We’re very inspired by these Part I knowledge, which represent a vital milestone for our vaccine know-how platform and echo the early success of our personalized cancer vaccine,” stated George E. Peoples, M.D., chief medical officer of Orbis Health Solutions. “Following additional knowledge evaluation and discussion with regulatory authorities, we stay dedicated to initiating a bigger Part II trial that can transfer us one step closer to bringing this essential treatment to patients as quickly as potential in order that we will help address this global health emergency.”
These trials are notably essential as a result of if profitable, they are going to present definitive proof of idea for the platform that might be quickly utilized to future vaccines to assist with new viruses and health concerns within a matter of weeks versus months to years.

“Simply as COVID-19 didn’t exist a few years in the past, other diseases and viruses will evolve,” Wagner says. “The proprietary supply platform for the Orbis vaccine supplies a blueprint that may be up to date rapidly with completely different DNA info, which permits for fast vaccine development and deployment to address the following viral or organic threat. This platform has the potential to save many lives each now and in the future.”
