The organization hopes that the invention of new effective vaccines will cut the number of tough cases of diseases caused by this infection, and, respectively, the fatal cases.
"If we act smart, we'll be able to get over hospitalizations, deaths and tragedies related to this pandemic", he said.
Besides, the WHO observes the increased number of new cases of infection worldwide - first time over the last 45 days.
Earlier, WHO Director General Tedros Adhanom Ghebreyesus claimed it is too soon for the governments to rely solely on vaccination programs. He also criticized the developed countries for excessive piling up of the stocks of vaccine, which complicates the process of supply of vaccines to poor countries.
