Texas-based genetic engineering company claims | US scientists have completed a coronavirus vaccine

Scientists at Greffex, a Houston, Texas-based genetic engineering company, claim they've created a CORONA VIRUS vaccine. 
The company told the Houston Business Journal that it had completed development of the vaccine and it is ready for animal testing and review by US regulators. 
It comes after UK scientists announced they'd begun testing their shot, and researchers at the University of Texas at Austin announced they'd made compound they believe can serve as a vaccine.

Greffex said that, for the sake of safety, its scientists did not use any form of the coronavirus itself - either live or inactivated - to make its vaccine. 
Most vaccine contain either live attenuated virus or an inactive form of the pathogen. 
However, the coronavirus is so poorly understood, has spread so quickly and has killed enough people that scientists at Greffex did not want to risk exposure that could trigger the life-threatening illness known as COVID-19. 
Scientists at the genetic engineering company have instead built their vaccine on an adenovirus. 
Adenoviruses are among the most common causes of viral respiratory infections, accounting for between two and five percent of colds. 
They're also widely used in the making of vaccines. 
Other companies are basing their candidate vaccines on ones previously developed during the SARS outbreak but abandoned once the virus subsided within six months. 

Scientists at the University of Texas, Austin, had to recreate a molecule that makes up the spike protein on the surface of the coronavirus (now know as SARS-CoV-2) in order to create a three-dimensional map of the structure. 
And the compound they made to do so itself can work as a vaccine, triggering an immune response to the virus, they believe. 
Like the UT Austin team and their collaborators at Moderna Therapeutics, the Greffex team believe that their process for production is among the fastest available to produce a vaccine. Read More

Beneifits of Black Seed Oil 2020

People have used  black seed oil  for its therapeutic benefits for thousands of years. Studies suggest that this oil may offer many health and cosmetic benefits, such as aiding weight loss, improving skin conditions, and even treating cancer and diabetes.

Nigella Sativa is a medicinal plant commonly used worldwide in various traditional medical systems. Originally from Egypt, also known as black cumin oil. The annual flowering plant belongs to the Ranunculaceae family and is an excellent phytomedicine.  Nigella oil is known for its diuretic , antihypertensive, antidiabetic, anticancer, immunomodulatory, antimicrobial, antihelmintic, analgesic and calming, spasmolytic, bronchodilator, anti-inflammatory, anti-tussive, gastro-protective, hepatoprotective, low-density lipoprotein properties. lowering cholesterol, protective and antioxidant kidney properties. The world is going through difficult times. It's the race against time to find a vaccine against the new coronavirus (COVID-19) every day becomes more difficult. Many articles with their first research results on the pathophysiology of COVID-19 infection give some clues to invent a cure for this pandemic. The importance of immunomodulation in the human body. A recent stud...
