MONTREAL, QC, May 7, 2021 (Press Release) – Numera today released the latest update of its Herd Immunity Tracker. This report will be published weekly for the remainder of the year. Its purpose is to complement available information on COVID-19 vaccination rates with timely estimates on projected times remaining until 70%+ immunity for all major economies.

Worldwide vaccination rates stalled over the past week, increasing the number of months towards 70%+ immunity by 4.3% to 11 months. In developed markets, the slowdown occurred primarily in countries with high vaccine coverage, now starting to experience lower demand from the unvaccinated population.

In the US, daily vaccination rates are down 35% since mid-April, pushing back the projected timeline to 70%+ immunity by one month to mid-July. The slowdown coincides with the temporary suspension of the J&J single-dose vaccine. In other developed markets with high vaccine coverage, like Britain or Israel, the slowdown this week reflects primarily a low take-up rate among the unvaccinated population.
