How many antibodies protect against "omicron" is not clear at the moment. This was told by the head of the Gamaleya Center Alexander Gintsburg.
“No one calculated the titer of protective bodies to the “omicron,” the academician noted. - I haven't seen any experimental data. No such studies have been carried out at our institute either. Still complicated by the fact that the "omicron" is rapidly changing. But, of course, new information on antibodies is needed.”
From February 21, according to a new order of the Ministry of Health, Russians will be able to receive a QR code in the presence of antibodies. However, how many antibodies are needed for protection to be considered complete is again unknown, since a new Omicron strain has arrived, and the number of protective antibodies needs to be recalculated, Alexander Gintsburg believes.
Previous experiments have shown that 300 BAU - "binding antibody units" protect against "delta". Alexander Gunzburg spoke about this earlier, referring to a joint study by the Center. N.F. Gamaleya and the Department of Health of Moscow.
Other virologists agree with him.
“Undoubtedly, new studies need to be carried out, since the protective titer for each strain was different, these data were cited by WHO,” she noted in an interview with. Ru" Head of the Department of Virology, Faculty of Biology, Lomonosov Moscow State University. M.V. Lomonosov Olga Karpova.
“We need to look at the virus-neutralizing ability of people who have either been ill or have been vaccinated with different vaccines. But taking into account the peculiarities of infection with "omicron", which for the most part does not lead to a severe course of the disease, I do not consider this a priority. I think that in the presence of the level of antibodies, which are considered to be protective for the "delta", we can consider this person protected from the "omicron", - the expert noted.
