The European Center for Communicable Diseases Control and Prevention has called for strengthening surveillance and vigilance efforts, in view of the steady rise in the number of infections with new strains of the Omicron (Omicron 5) mutant. caused by corona virusAfter it increased, especially among those over 65 years of age, by 32% during this week compared to last week, which is equivalent to 62.8% of the peak level reached so far.
The center’s last periodic report recommended accelerating campaigns to distribute the fourth dose to those over 65, who have chronic diseases, or who suffer from a deficiency or defect in the immune system. The European Medicines Agency had warned of poor coverage of the fourth dose, which did not exceed 21% of the elderly, and 45% among those with immunodeficiency.

The European Center had advised not to wait until autumn to take the fourth dose, because it enhances the immune response at a high rate, and protects once morest dangerous symptoms when infected, especially that the new strain of the Omicron mutant has a transmissibility ability that exceeds all previous mutant, and one of its characteristics is that those who contract it can To be injured a second or third time.
The center’s experts say that the booster dose is the way to protect once morest the virus at this stage of rapid and intense flow, especially since it is now out of the question to return to the closure measures or the strict preventive measures that were imposed by the health authorities in the past period. It should be noted that some European countries are still imposing quarantine on the infected, although monitoring of its implementation has declined in the recent period.

The European Medicines Agency had reduced the interval between two doses of the vaccine once morest Covid-19 to three months, following recent studies showed that the effectiveness of the dose decreases significantly following four months of taking it, in addition to the fact that new mutations usually require some adjustments to the vaccine dose of in order to ensure its effectiveness. The agency also confirmed that taking three doses per year does not pose any danger and does not result in symptoms of little importance, noting that recovery from infection is equivalent to a dose of the vaccine.
While the health authorities in Italy, Spain and France have ruled out a return to imposing the strict measures that were adopted during the previous epidemic waves, the German Ministry of Health stated that the measures to close schools next fall are ready in the event of a rapid and massive rise in infections, or the health system is subjected to pressure or the emergence of new mutations.
And the European Medicines Agency stated that pharmaceutical factories are ready to produce sufficient quantities of vaccines adapted to the characteristics of the new strain, that is, vaccines that contain samples of the original mutant that appeared in Wuhan, along with samples of the Omicron mutant. The US Drug Agency had asked the producing companies to prepare a new vaccine containing samples of the Wuhan virus and the Omicron 5 mutant.
Agency experts say that it is not yet known if the new vaccines provide protection once morest transmission, but they tend to believe that they provide limited protection, especially since recent data from the companies “Pfizer” and “Moderna” indicate that the antibodies generated by the new generation of vaccines are Double that generated from currently circulating vaccines.
Experts from the European Center for the Prevention and Control of Communicable Diseases advise not to neglect the use of antivirals and monoclonal antigens to treat serious infections, as a decrease in their use has been observed with the spread of vaccines, and the resulting widespread belief that they are sufficient alone to protect once morest dangerous symptoms. Experts say that most of the deaths recorded among the vaccinated people were people with chronic diseases or suffering from a deficiency or defect in the immune system.
