Scientists at the University of Pittsburgh School of Medicine in the United States announced Thursday the development of a possible vaccine against the emerging coronavirus, which causes Covid-19, in a statement posted on the university's website.
Vaccination is a preparation that is given to a person to form immunity in his body against a specific disease, and it consists of disease germs that have been killed or weakened, or parts thereof, and when entering the body stimulates the immune system to form antibodies to a specific disease and immune memory, so that the immune system remembers the pathogen that causes By attacking it and eliminating it immediately when it enters the body the next time.
"Our ability to rapidly develop this vaccine was the result of scientists with expertise in a variety of areas of research working together with a common goal," said co-author Dr. Louis Fallow, professor and head of the Department of Dermatology at Pittsburgh College of Medicine.
The authors named the vaccine "PittCoVacc" , an acronym for Pittsburgh Coronavirus Vaccine.
The new vaccine uses in vitro-manufactured parts of the viral protein to build immunity to the emerging coronavirus in the same way as the current flu vaccine.
The researchers also used a new approach to deliver the drug to the body, called a microneedle array, to increase efficacy. This array is a finger-sized patch of four hundred small needles that transfer the spike protein pieces to the skin, so that the immune response is stronger.
The patch works like a wound patch, then the mini needles - made entirely of sugar and protein bars - dissolve into the skin.
"We developed this based on the original method used to deliver the smallpox vaccine to the skin, but with a high-tech and more efficient version for the patient," Fallot said.
Currently, researchers are applying for approval of the new vaccine from the US Food and Drug Administration, to start the first phase of human clinical trials in the next few months.
Finally, we are starting to hear good news in the world. we hope that treatment arrives soon.
