Infectionist Timakov: do not run to get vaccinated if the level of antibodies is below 300 
If the level of neutralizing antibodies is below 300, do not make an urgent decision on vaccination. This is how the infectious disease doctor Yevgeny Timakov estimated the need for vaccination with an insufficient number of antibodies to protect against the delta strain, Life reports.
Earlier, the head of the Gamaleya Center, Alexander Gintsburg, named a sufficient number of antibodies to protect against coronavirus. According to him, 300 antibodies in international units are needed for complete protection. The specialist called an indicator of 500 antibodies and above ideal for preventing infection. With insufficient immune protection, the specialist urged Russians to be vaccinated or re-vaccinated.
According to Timakov, 150 neutralizing antibody units were initially required to protect against the Wuhan variant of COVID-19.
The specialist noted that the level antibodies below 300 does not always mean that a person can get the delta strain of COVID-19.
“This does not mean that a person who has 50 or 100 antibodies will be seriously ill with coronavirus. He may have fewer antibodies, but they will be of better quality. And there is no need to go urgently to get revaccinated, “Timakov said.
The specialist added that it makes no sense to go re-vaccinated against coronavirus earlier than six months later.
Since November 8, residents of Russia can receive new certificates of vaccination against coronavirus, medical contraindications to it or a past illness. The document is available in English and Russian, and can be obtained in paper or electronic form. The certificate will contain detailed information about the owner, data from SNILS and the compulsory medical insurance policy, as well as contraindications to vaccination.
