Mass vaccination with the Russian drug "Sputnik V" continues in Belarus. According to world practice, physicians who are at risk are vaccinated first. It is planned that at least 20 thousand doctors will receive this vaccine. A Chinese vaccine produced by Sinopharm is being tested in Belarus. The drug is already approved not only for emergency use, but also for widespread use. Both vaccines involve two doses of injection. The second component is administered to a person 21 days later to strengthen the immune system. By the way, mass vaccination of Belarusians should begin in April. A presentation of a domestic vaccine is expected in the fall.
