An official at the World Health Organization said that studies of the models under certain circumstances show that about 60 to 70% of the population needs to be immune to curb or stop the transmission of Covid-19.

Noting that the World Health Organization cannot determine the exact number of the population that needs to be vaccinated, Catherine O’Brien, Director of the Department of Immunization, Vaccines and Biology at the World Health Organization, said during a hypothetical briefing, that “the answer to this can come from studies of models. “.

She pointed out that “these model studies under various circumstances concluded that about 60 to 70 percent of the population need to be immune, and this is assumed to be in order to achieve a reduction or stopping the transmission of the virus.”

She added, “This depends of course on what the vaccines will perform.”

The number of Covid-19 cases worldwide has crossed the 61 million mark, while the number of deaths has crossed 1.4 million, according to the latest data from Johns Hopkins University.
