Monthly routine and SARS-CoV-2 campaign vaccine doses per vaccinator, by WHO Region estimated nurse density. Notes: 1. Data points represent the total monthly vaccines delivered divided by the total number of vaccinators in a country. Vaccinators = nurse density per capita × country population (20,000,000) × percent of nurses that provide immunization services (46%). 2. Nurse data are from WHO Global Health Workforce Statistics [18]. We used the median value from countries at the most recent available date and divided by country population estimates [14] to calculate per capita values and then categorized by WHO Region. 3. Routine immunization programs account for 3% absenteeism (baseline). SARS-CoV-2 vaccination programs account for 3% absenteeism (baseline) and an additional 8% absenteeism (during pandemic). 4. HCWs target group removed because volume contribution was too small to depict in the figure.
