World Health Organization (WHO) director-general Tedros Adhanom Ghebreyesus has called on countries to vaccinate 70% of their population against the coronavirus by July 1, 2022, RIA Novosti reported.

Ghebreyesus told a news conference in Geneva on the occasion of the second anniversary of the discovery of COVID-19 that he urges everyone to promise in the New Year to assist in the respective vaccination campaign of 70% of the world’s population by mid-2022.

He added that the Delta and Omicron variants of the coronavirus could lead to a “tsunami” of new cases of this disease.

Of particular concern is the fact that the Omicron variant is more contagious, added the head of the WHO.
