What is the proportion of unvaccinated against corona in intensive care units?
The figures show that the rate of hospitalizations and intensive care units is significantly higher among patients who did not receive the vaccination.
In a report published by the French newspaper "Liberation", the writers Cedric Mathieu and Jacques Bizzi review some statistics and official data about the rates of hospital admissions and intensive care departments for patients who are not vaccinated against Corona.
A survey conducted by the French Society of Anesthesia and Resuscitation on December 28, which included 165 intensive care units (that is, about a third of intensive care units in France), revealed that of the 900 “Covid” patients present in intensive care, 80% of them did not have the vaccine.
According to the Department of Research, Studies, Calendar and Statistics, which is an official source that gives comprehensive data on the vaccination status in France for people who have undergone critical care (not only in intensive care), between December 6, 2021 and January 2, 2022, the percentage of unaccompanied patients was Those vaccinated in hospitals are about 58%.
According to the latest figures from the British National Center for Intensive Care Audit and Research, the proportion of unvaccinated people in intensive care units in the United Kingdom during the first three weeks of December reached 61%.
According to data collected by the Robert Koch Institute in Germany during the last three weeks of December 2021 and the first week of January 2022, the unvaccinated represented 62% of hospital admissions, compared to 38% of those vaccinated.
During the same period, unvaccinated people accounted for 73% of intensive care admissions.
For its part, the German Society for Emergency Medicine indicated in a press release on January 13, that between December 14, 2021 and January 12, 2022, 68.5% of admissions to intensive care were unvaccinated.
Is coexistence with the Corona virus possible after the largest vaccination campaigns in history?
More than two years after the start of the Corona virus pandemic, which confused the entire world with the accompanying exceptional measures that affected almost all aspects of life, the question that arises is: How long will the pandemic last and whether coexistence with the virus became possible after the largest vaccination campaigns in history ?
Researchers Therese Raphael and Sam Fadli say in a report published by Bloomberg News Agency and quoted by the German News Agency, that the balance of power between humans and the virus is shifting.
The researchers considered that since we are better armed against the Corona virus in light of the positive results provided by vaccines, "we no longer need to hide and wait for a viral wave to pass. This means that it is time to change our response to Covid-19."
Omicron affects the body differently
Omicron appears to affect the body differently than previous mutant.
A study from the University of Hong Kong Medical School suggests that Omicron may replicate itself in the lung more slowly than the delta mutant, which would give the immune system more time to respond, according to a Bloomberg report.
As we enter the "endemic stage of the virus", the researchers said, there is confusion about what a renewed approach should look like.
On Monday, Spanish Prime Minister Pedro Sanchez called for a discussion at the level of Europe on developing a type of response similar to the current handling of influenza, for example.
The United Kingdom has extended "Plan B" rules for another 3 weeks, but has relaxed its testing and travel policies, and Prime Minister Boris Johnson is pressing for existing restrictions to be lifted.
It is too early to declare victory, of course, injuries are rising sharply, there is still a worrying number of deaths from “Covid-19”, and in addition, there are many areas where health services are under severe pressure.
However, the overall picture of the pandemic is encouraging. Omicron infections in South Africa reached their peak about a month after the start of the wave.
Data from South Africa and elsewhere confirm that the newer, albeit more contagious, mutant causes less severe disease, with lower levels of hospitalization, shorter hospital stays, and fewer deaths.
Can a person be infected with a third or fourth time with corona?
The Omicron mutant has doubled the rates of re-infection with the emerging coronavirus, but experts stress that symptoms become less severe each time due to the natural immunity and immunity conferred by vaccines.
In a report published by the French newspaper "Leparisien" by Yves Leroy, the writer said that in light of the high incidence of Corona virus after the emergence of the Omicron mutant, the Health Insurance Administration and the National Agency for Public Health in France were unable to issue accurate data on the proportion of infected people. Virus 2 or 3 times or more.
In this regard, confirms Jean-Daniel Leliever, Head of the Department of Infectious Diseases at Henri Mondor Hospital in Creteil, "Cases of infection for the third and fourth time are rare, but they do exist. It has become more common with Omicron."
He adds, "The immune response varies from person to person in its strength and duration. It changes with the appearance of the mutant, especially at the level of the mucous membrane, which leads to less severe forms. This is why immunity is acquired from severe forms after infection with the virus or receiving the vaccine. Then the factors enter Others, as it differs between spending most of your time at home or in transportation and markets.
Michel Connier, Professor of Immunology at the University Hospital of Rennes, France, believes that the decline in the severity of symptoms is logical, stressing that "it is very common in traditional coronaviruses to renew the infection, and the evidence for this is that we catch colds every winter. And immunity lasts between 6 months and a year. And it does not prevent infection again the following winter. These infections are superficial, but the danger of Covid-19 is due to the fact that it affects the lungs and is not limited to the mucous membranes and the upper respiratory tract.”
"Having the disease is equivalent to being vaccinated in some cases. We can't make predictions, but we can say that the more we get sick, the more immune we become. On the other hand, we can worry about those who are immunocompromised or those who suffer from the consequences of previous infection." Symptoms may be more severe than before.
Scientists have found a gene that can reduce the severity of infection with the Corona virus by 20%
Researchers have discovered a gene that reduces the severity of infection with the Corona virus by 20%.
Scientists said their discovery will help manufacture effective drugs against the virus.
This discovery also explains why the symptoms of infection with the virus vary, as some suffer from mild symptoms, while others develop more severe symptoms.
And the German news agency quoted the British newspaper, “Daily Mail”, about the researchers saying that the gene causes the body to secrete a protein, which is effective in breaking down the Corona virus, which causes “Covid-19”, as the study published on the York Alert website.
The researchers at the Karolinska Institutet in Sweden indicated that the gene was found in one out of every 3 white people of European descent.
The study, published in the journal Nature Genetics, concluded that the gene is present in 8 out of 10 people of African descent.
The gene determines the length of a protein called "OAS1", and when it is longer, it can better break down the Corona virus.
"The beginning of our understanding of genetic risk factors in detail is key to developing new drugs for the Corona virus," said researcher Brent Richards at McGill University, a co-author of the study.
Scientists in Texas develop a new vaccine against "Covid-19"
A new vaccine for Covid is being developed by scientists in Texas using a decades-old traditional method that would make production and distribution cheaper and easier in countries hardest hit by the pandemic, where new variants are likely to occur due to low vaccination rates.
An article published by the British newspaper "The Guardian" stated that a team led by Dr Peter Hotez and Dr Maria Botazi from the Texas Children's Hospital Center for Vaccine Development at Baylor College of Medicine, has developed vaccine prototypes against SARS and MERS since 2011. , which they reconstructed to create a vaccine called Corbevax.
The article noted that although more than 60 other vaccines are in development using the same technology, Botazi said their vaccine is unique because they do not intend to patent it, allowing anyone with the ability to produce it, to reproduce it.
"Anyone who can make hepatitis vaccines or has the ability to make a protein based on microbes like bacteria or yeast, can replicate what we're doing," she added.
The article indicated that clinical trial data for the new vaccine has not yet been released due to resource limitations, but Texas Children's Hospital said that it was 90% effective against the original "Covid-19" strain and more than 80% effective against the delta variant, and the vaccine's effectiveness is currently being tested. Against the omicron variant, the vaccine-making process involves the use of yeast, the same way hepatitis B vaccines are produced.
According to the article, the "Corbifax" vaccine uses protein subunit technology, which places an actual piece of the "Covid-19" coronavirus protein in yeast cells, then the yeast cells copy the vital protein and then the protein is introduced to the immune system.
And Botazi continued - as stated in the report - "We make the protein directly and synthetically in the laboratory using the yeast system, which in turn makes a protein similar to the protein made by the virus, then we immunize the protein, then the body processes it and presents it to the immune system."
