It is much more difficult to eradicate the pandemic when the global spread of the novel coronavirus is so big, said for BNT pulmonologist Dr. Alexander Simidchiev referring to the so-called Spanish flu, which circulated for 4 years. In his view, the coronavirus morbidity depends on factors such as the environment, the human behavior and the transmissibility of certain coronavirus strains. 

According to immunologist Professor Andrey Chorbanov, Covid-19 will disappear, if 70% of the population receives vaccines and the novel coronavirus infects 70% of the world’s population.  

The restrictive measures can stop the growth of the pandemic process and vaccines can reduce its frequency, added Dr. Alexander Simidchiev.
