The researchers said the United States is among the countries predicted to fall short of WHO’s 2022 COVID vaccination target, along with many other countries in Europe, Asia and Africa.
In October, WHO set a goal for countries to vaccinate 70% of their populations by mid-2022.
More than 100 countries are not on track to meet this goal, according to forecasts made by Our World in Data, last updated Tuesday.
Our World in Data projections have been compiled using official data, with the current vaccination rate for each country calculated as the average number of people who received the second dose of vaccine in the last 14 days. The researchers then suggested that these vaccination rates would remain unchanged until the WHO’s mid-2022 target is met.
“By adding this expected proportion to the proportion of the population that has already been fully vaccinated, we predict what proportion of people will be fully vaccinated on July 1, 2022,” the researchers said. “We are excluding from our projections countries that have not reported figures for more than 30 days.”
They acknowledged that their method did not account for variables such as potential vaccine shortages, changes in vaccination roll-out rates, or new government policies.
Some of the countries that were not projected to vaccinate 70% of the population by the middle of this year include Estonia, Jamaica and Nigeria.
Fewer than 50 countries have already reached the 70% threshold, including Qatar, Portugal and Japan.
Saudi Arabia, Russia and Hong Kong were among those still under the 70 percent threshold, but they felt they were on track to meet the WHO target by mid-2022.
