Just when we thought the corona was already behind us, it seemed to be raising its head again: two new strains of the omicron strain are spreading around the world as well as in Israel. The coefficient of infection in Israel is on the rise, the number verified in recent days has risen by about 16% and stands at a number of about 74,000 patients in recent times. The strains, called BA.4 and 5.BA, were first diagnosed in South Africa and appear to be spreading massively around the world. According to the FDA, their spread will even worsen this coming winter. How dangerous are they and how do they cope? here:
What we know about the varieties BA.4 And 5.BA?
The BA.4 and 5. BA strains are in fact sub-strains of the infamous Omicron, and according to the World Health Organization they have spread to many countries around the world. As mentioned, the varieties were first identified in South Africa and have since become dominant in the Western world, throughout the United States and Europe and also in Israel.
Health authorities in Europe and the US have described the variants as “worrying”, but at present it is still unclear what their level of risk is. They are derivatives of omicron, it will be possible to diagnose their level of danger more accurately and thus it will be possible to treat patients more effectively and give them the appropriate treatment. These strains are different from earlier alpha and delta strains. The latter are not “derivatives” of other strains and are considered viruses. Independent. “
God-FDA Contact Pharmaceutical Manufacturers: Develop Omicron Vaccines
The team of vaccine experts from the Food and Drug Administration (FDA) recently asked the pharmaceutical companies to develop vaccines that are adapted to give the strains of Omicron as early as this fall, due to their spread. This is the first time the panel of experts has addressed the vaccine manufacturers with such a request. Pharmaceutical companies that have developed vaccines against the corona virus, including Modern and Pfizer, have targeted the vaccines against the original corona strain that first appeared in China, sometime in 2019. But because the virus developed rapidly during the epidemic, vaccines have lost their effectiveness against infection and minor illnesses, although they still protect to a high degree from severe coronary heart disease.
The vaccines target the spike protein that the omicron variant “uses” to invade human cells. The omicron variant is the most dramatic example of a corona mutation, with more than 30 subspecies. This is one of the main reasons why the omicron caused such a massive wave of infections last winter, despite the fact that masses of people were vaccinated and even four vaccine doses.
“The omicron continues to spread to give more contagious variations,” said Dr. Peter Marks, who heads the FDA’s vaccines division, adding that the U.S. is facing another corona wave this fall and winter. As the virus develops, the usefulness of the vaccines fades and in the cold seasons people will spend more time indoors, a situation where the virus can spread much more. He added that as the development of the vaccine adapted to the omicron strain becomes more effective, the morbidity will decrease significantly.
The four current doses of vaccines are only 19% effective in preventing omicron infection in adults aged 18 and over. This is according to data presented by the American Center for Disease Control and Prevention. As mentioned, sub-variations of the omicron are considered to be more contagious, and the current vaccines available on the market have less of an effect on them. Although the pharmaceutical companies Pfizer and Moderna have already announced that they are ready with vaccines adapted to Omicron and its sub-strains, they are waiting for FDA approval, in the hope that the vaccines will be marketed as early as this fall.
When will the development of new varieties of corona stop?
According to world prevailing forecasts, the Corona is expected to stay with us until 2024 at best. Also, looking at the history of the epidemics, a herd vaccination of at least about 90% of the world population is required for the virus to stop producing new mutations. At the moment, we are still far from a global herd vaccine, and the corona will probably stay with us for a long time to come.
