After the new Corona virus has become a threat that threatens the whole world approximately 9 months since its appearance, we are all anxious to know what happens every minute, in light of the tremendous development that Covid-19 has brought to our lives. lives.
In this framework, “Masrawy” provides a daily service that includes showing everything you want to know about the latest developments in the emerging coronavirus, from the appearance of new symptoms or the appearance of a different mutation, as well as the development of vaccines and drugs, in short.
The mystery of fatal cases
New research revealed that a large proportion of patients who develop life-threatening forms of “Covid-19” suffer from genetic or immune defects that weaken their ability to fight the virus.
In the study published in the journal Science, Covid Human Genetic Effort, an international consortium that aims to discover congenital defects in the immunity underlying severe forms of Covid-19, describes two defects in patients with severe Corona disease that cause them they prevent the production of a first-line immune molecule called the interferon type. 1, which are 17 proteins that infected cells make to help stop the spread of whatever is affecting them.
The researchers found that more than 10% of those infected with severe “Covid-19” have deceptive antibodies that attack the immune system instead of the virus that causes the disease, according to “Russia Today.”
Crown and a brain tumor
A team of scientists revealed that the “Corona” virus is capable of causing a tumor in the brain and accelerating the development of the tumor, as it enters the brain and associates with cells of the nervous tissue that participate in the development of cancer.
And a team of Turkish doctors from Bezmalem Vakif University announced that part of the virus is associated with glial cells and nerve cells of nervous tissue, to surround these cells with nerve cells, which provides the conditions for the generation and transmission of nerve impulses, according to Sputnik.
The effectiveness of the vaccine.
British scientists have warned that the first vaccine to be produced to fight the emerging corona virus will not be 100% effective and is unlikely to prevent people from contracting the disease.
According to the British newspaper Daily Mail, experts said the vaccine can only reduce symptoms in dangerous people and will be partially effective, emphasizing the need to be careful when finding a vaccine and releasing it to humans.
Vaccine No. 11 is entering the final phase of trials
The American biotechnology company “Novavax” announced that it has started the third phase of clinical trials of its Corona vaccine in Great Britain, thus becoming the eleventh experimental vaccine in the world to reach this final stage.
The company said 10,000 volunteers between the ages of 18 and 84 will participate in the trials.
“Due to the current high level of virus transmission, and given that this level is likely to remain high in the UK, we are optimistic that this phase III critical clinical trial will benefit from rapid volunteering and a short-term evaluation will be available.” The statement cited Gregory Glenn, the company’s director of research and development. For the effectiveness of “the vaccine”, according to the agency “AFP”.
