[Southern + December 9th] According to British media reports, Pfizer Pharmaceuticals claims that after receiving 3 doses of new crown vaccine , it can effectively prevent the latest new crown mutant strain Omickron .
It is reported that Pfizer Pharmaceuticals said that two doses of the new crown vaccine are not enough to effectively prevent Omickron infection, but if one more dose of enhanced shot is given, it can effectively prevent any serious diseases caused by Omickron.
Preliminary experimental tests show that Pfizer Pharmaceuticals' third dose of enhanced vaccine has produced a stronger antibody response to Omickron, and the antibodies against Omickron are 25 times that of the two doses of the vaccine. At the same time, it can increase the level of T cells, providing additional promotion to the immune system to prevent serious diseases. Pfizer Pharmaceuticals officials revealed that it will be officially launched in March 2022.
At present, the experimental results are only published in a press release, have not been peer-reviewed, nor have they been published in scientific journals.
Previously, Siegel, head of the laboratory of the South African Institute of Health, said: "Although there will be breakthrough infections, vaccination enhancers will help reduce the risk of infection, especially severe infections that can cause the worsening of the disease." Siegel called on people who have not received the additive to get the third dose of the vaccine, and said that people who have been infected with the new coronavirus should also get the new coronavirus vaccine.
Omickron was first confirmed in South Africa on November 9 local time, and reported it to WHO on November 24 local time. It is the most evolved so far, with 32 mutations, and the number of mutations is twice that of delta . It is highly contagious and vaccine resistant and has much more alterations to its spike protein than other variants. In order to prevent the spread of Omikeron, many countries have urgently canceled flights, restricted passengers' entry, and upgraded prevention and control measures.
WHO Emergency Program Executive Director Michael Ryan said there is no sign that Omickron will cause more serious illness than Delta, and existing vaccines should protect Omickron from the worst-case scenario. "So far, we have very efficient vaccines in terms of serious diseases and hospitalizations caused by COVID-19 infection and have been proven to be effective against all mutant strains. Therefore, there is no reason to think that Omickron is not like this."
