When will the pandemic end? This is the question asked since the first part of 2020. The answer depends on the speed which the population is immunized. A Bloomberg analysis shows that it could take about 7 years for the world’s states to vaccinate 75% of the population.

Scientists estimate that an immunization of between 70% and 85% of the population is needed for things to return to normal. Some countries are making much faster progress than others, but so far the vaccine has only been administered to about 120 million people worldwide.

Israel, the country with the highest vaccination rate in the world, is heading for 75% coverage in just two months. The United States will immunize 75% of the population by the end of 2021, if it maintains the current rate of 1.3 million doses administered daily.

But while rich Western countries are vaccinating at a higher rate, poor countries are still waiting for access to the vaccine.

For example, Canada needs almost 10 years to immunize its population at the current rate, while China 7 years to vaccinate 75% of its 1.4 billion population.
