In a new spark of hope on the road to trying to stem the outbreak of the emerging corona virus, a group of scientists has developed a test vaccine for “Covid 19”, which has already proven successful with mice.
According to Sky News Arabia, the scientists adopted a “different” method of injecting the vaccine into rat bodies, which in turn produced antibodies to the disease within two weeks.
Researchers were developing vaccines for other coronaviruses, including the Corona virus associated with “Middle East Respiratory Syndrome (MERS), and they were able to use the system they were working on to produce this vaccine to quickly develop an experimental vaccine for Corona.
Scientists have benefited from their “high” protein, which appears as burrs and gives corona its distinctive shape, according to the NIH Research Matters blog of the US National Institutes of Health.
The method used by the team of researchers, which includes scientists from the University of Pittsburgh, America, to introduce the vaccine effectively into the bodies of mice, depends on a “patch” containing a microscopic needle.
The idea is to use a “patch” containing hundreds of tiny needles that penetrate the skin of mice and dissolve the vaccine.
The National Institutes of Health have indicated that the immune system is very active in the skin, so delivering vaccines in this way can produce a faster and more robust immune response than subcutaneous injection, according to US News Fox News.
When those vamps were used, 3 different vaccines for MEA stimulated the production of antibodies to the virus, and levels of antibodies in mice continued to rise throughout the 55-week trial period.
Using the knowledge gained from developing a “MERS” vaccine, the team produced a similar vaccine using a vamp, targeting the high protein of corona, and the vaccine resulted in “prolific” production of antibodies in mice within two weeks.
Despite the promising results reached by the scientists, they warned that the vaccinated animals were not tracked “for a sufficient period” to determine whether the long-term immune response was achieved similar to what happened in the trial of the “MERS” vaccine, and that the mice were not exposed to Corona infection distance.
