The agency said that two doses of the “Pfizer” or “AstraZeneca” vaccines provide limited protection against “Omicron”, but the booster doses of the two vaccines raise the level of protection to between 70 and 75 percent.
And she explained in a statement that the results of analyzing data from 581 people who tested positive for “Omicron” showed that the “Pfizer” and “AstraZeneca” vaccines provided lower levels of protection against the symptoms of the mutant, compared to what it was doing with the mutant “Delta”.
She added: “Preliminary data showed that the effectiveness against the new mutant increases significantly in the early period after a booster dose, providing protection by 70 to 75 percent from symptomatic infection,” according to the British “Sky News” network.
And the statement continued: “We need more time to know the exact level of protection provided by the vaccines against Covid 19 for the mutant Omicron, but the initial results show resistance for symptomatic cases.”
On Friday, the Centers for Disease Control and Prevention in the United States revealed that 40 new cases of the “Omicron” mutant had been recorded in the country at two restaurants with vaccines against the Corona virus.
According to the center’s head, Rochelle Walinsky, nearly three-quarters of Omicron infections in the United States are from people who have received the vaccine.
But the positive sign announced by Walinsky, is that those infected with the new mutation “currently suffer from mild symptoms.”
She pointed out that private data on the new mutant is still limited, pointing to the Centers for Disease Control and Prevention’s work to analyze the data and information in its hands, to anticipate what “Omicron” may cause.
And the British newspaper, “The Guardian”, quoted Walinsky as saying: “What we generally know is that the more mutations in the mutant, the more we need to boost immunity, which is what the booster doses of the anti-Corona vaccine contribute to.”
The official explained that the symptoms of “Omicron” that have been monitored so far are mild, and include coughing, congestion and fatigue, stressing that no deaths have been recorded due to the mutant in the United States.
