The United States is among the countries expected to miss the WHO’s 2022 vaccine target for Covid, researchers have said, along with many other countries in Europe, Asia and Africa.
In October, WHO set a target for countries to immunize 70% of their populations by mid-2022.
According to projections from Our World in Data, last updated on Tuesday, more than 100 countries are not on track to meet this target.
Our World in Data projections were compiled using official data, with the current immunization rate for each country calculated as the average number of people who received their second dose of vaccine in the past 14 days. The researchers then assumed that these vaccination rates would remain constant until the WHO target of mid-2022.
“By adding this expected share to the share of the population that has already been fully vaccinated, we predict how much of people will be fully vaccinated on July 1, 2022,” the researchers said. “We exclude from our projections countries which have not provided figures for more than 30 days.”
They recognized that their method did not take into account variables such as potential vaccine shortages, changes in vaccination deployment speeds, or new government policies.
Some of the countries that were not expected to immunize 70% of their population by the middle of this year included Estonia, Jamaica and Nigeria.
Less than 50 countries have already reached the 70% threshold, including Qatar, Portugal and Japan.
Saudi Arabia, Russia and Hong Kong were among those who had not yet surpassed the 70% threshold, but were considered on track to meet the WHO target by mid-2022 .
