23 Feb in 19:00 By Vestnik Kavkaza The absence or delay of vaccination against coronavirus anywhere in the world could lead to the spread of new types of infection on the planet and nullify the effectiveness of existing vaccines, said WHO Director General Tedros Adan Ghebreyesus. According to him, if vaccination is not carried out in some places or is delayed, they will become a field for the multiplication of new varieties of coronavirus, and the vaccines used may become useless. In the South Caucasus, this seems to be realized only in Azerbaijan, where vaccination is in full swing. In Georgia and Armenia, it has not actually started yet.
