To test the effectiveness of the omicron vaccine on animals, they were vaccinated at the end of November, when data on a new variant of the virus emerged.

"It is planned to infect animals at the end of December, so in mid-January there will be data on the protection of the vaccine," said Maksyutov, quoted by RIA Novosti.

Earlier, the head of Rospotrebnadzor Anna Popova said that there are currently two patients in Russia who have been diagnosed with the omicron coronavirus strain.

Nikolay Malyshev, infectious disease doctor, doctor of medical sciences, in an interview with Nation News recalled the importance of adhering to preventive measures against the background of detecting omicron cases.
