COVID-19 Vaccine Doses: Who’s Got At Least One?

With COVID-19 vaccine rollouts well underway in some countries, a return to ‘normal life’ could come sooner than later.

That said, many jurisdictions have experienced serious delays and supply shortages that have made it difficult to distribute COVID-19 vaccine doses to their populations. As of mid-February, 130 countries had not been able to begin vaccinating at all.

This interactive chart from Our World in Data tracks the share of people in each country that have received COVID-19 vaccine doses so far.

The Global Vaccine Rollout

As of publication date, roughly 100 countries have begun vaccine distribution, with about seven different vaccines available for public use at this stage.

The sheer logistical challenge of doling out vaccines is immense. Experts estimate that 70-80% of the world’s population will need to be vaccinated to reach herd immunity. Additionally, some of the vaccines require two doses which adds extra time and complexity to the process.

Here’s how the various vaccines compare in terms of required doses and levels of effectiveness.

Pfizer/BioNTech295%
Moderna295%
Oxford/AstraZeneca270%
