The Omicron mutant is more likely to spread from the Corona virus than its Delta counterpart, cause less severe symptoms and make vaccines less effective, according to the World Health Organization, which indicated that its data is still incomplete.
The organization confirmed that the Omicron mutant has been detected in 63 countries so far, which confirms the recent statements of its officials.
She stated that Omicron appears to be spreading faster than the Delta mutant, which is currently responsible for most infections in the world. This speed of spread has been observed not only in South Africa, but also in the United Kingdom, where the delta mutant predominates.
The WHO cannot yet know – due to a lack of sufficient data – whether the high outbreak rate in the highly immunocompromised population is due to the fact that Omicron “escapes immunity, exploits a high underlying transmissibility, or is a combination of the two”.
The organization predicted “Omicron will outperform Delta in places where there is community transmission.”

However, data are still insufficient to determine the severity of the disease caused by the omicron mutant, although symptoms currently appear to be “mild to moderate” both in South Africa, where it first appeared, and in Europe.
With regard to vaccines against corona, the limited data available, as well as the genetic fingerprint of the omicron mutant, indicate a “reduction in efficacy” with regard to protection against “infection and infection”.
For its part, Pfizer and Biontech laboratories, which developed the Kominarty vaccine, one of the most effective vaccines against Corona to date, confirmed, on Wednesday, that its vaccine is still “effective” on the mutant Omicron after “three doses.”
Most countries that can afford the vaccines encourage people to take a booster dose, as is the case especially in Europe, which is facing a new wave of infections caused by the delta mutant, having significantly reduced health and lowered vaccination rates.
For his part, Anthony Fauci, the chief infectious disease expert in the United States, said that taking three doses of vaccines is the “optimal care” from Corona, but the US government still officially defines “full vaccination” as two doses of Pfizer / Piontech, Moderna or Moderna vaccines. A dose of Johnson & Johnson vaccine.
Fauci, director of the National Institute of Allergy and Infectious Diseases, told ABC News that health officials will continue to evaluate what should be considered a formal definition.

Asked if three doses of vaccines might be the new standard of care, Fauci said: “Well, I definitely think it represents the best care.”
“I mean, in terms of official requirements, the two doses of Pfizer/Biontech or Moderna or the dose of Johnson & Johnson still match the official definition of what is required. But I think if you look at the data, it becomes more and more clear that if you want to be protected in the way that Optimally, you really have to get a booster dose.”
Fauci added that it will take months to determine whether there is a need to receive annual booster doses of vaccines, explaining that he hopes, from an immunological point of view, that a single booster dose will be sufficient to provide greater protection than the six months provided by the initial vaccine.
