To do that, “we need to immunize all countries of the world,” explained Lancet editor-in-chief Richard Horton to The Jerusalem Post. “To reach herd immunity, about two-thirds of the world population – four billion to five billion people – need to be vaccinated. Each person has to have two doses – that is 10 billion doses of the vaccine.”
As such, the pandemic will not be solved by spring 2021, health experts said. It will not be over in 2022. And according to the most optimistic predictions, the skies will only really begin to open, and travel and tourism will resume, sometime between 2023 and 2024…
The unit predicts that the bulk of the adult population in advanced economies will have been vaccinated by mid-2022. Middle-income countries will take until late 2022 or early 2023.
“For poorer economies, mass immunization will take until 2024, if it happens at all,” the report said.
