Table 1 Definition of each indicator

COVID-19 vaccine doses administered per 100 people

Total number of COVID-19 vaccinations received per 100 people in the country's total population

COVID-19 vaccination rate

The proportion of the country's total population who have received at least one dose of COVID-19 vaccine, including the proportion of the population who have been fully vaccinated and the proportion of the population who have been partially vaccinated

share of people with fully vaccinated

The total number of people who received all doses prescribed by the initial vaccination protocol (e.g. 2 doses for Pfizer/BioNTech, Moderna, Oxford/AstraZeneca, etc. and 1 dose for Johnson & Johnson), divided by the country's total population

share of people only partly vaccinated

The total number of people who have received only their first vaccine dose, divided by the country's total population

cumulative confirmed cases per million

The cumulative total of confirmed COVID-19 cases per 1 million people in the country. The count can include reported possible cases

cumulative confirmed COVID-19 deaths per million

The cumulative total COVID-19 deaths per 1 million people in the country. The count may include reported possible deaths

daily cases per million

The total number of COVID-19 cases diagnosed per 1 million people per day in the country. The count can include reported possible cases

daily deaths per million

The total number of COVID-19 deaths per 1 million people per day in the country. The count may include reported possible deaths

the effective reproduction rate (Rt)

The reproduction rate represents the average number of new infections caused by a single infected individual. If the rate is greater than 1, the infection is able to spread in the population. If it is below 1, the number of cases occurring in the population will gradually decrease to zero

The moving-average case fatality rate (CFR)

The case fatality rate (CFR) is the ratio between confirmed deaths and confirmed cases. The moving-average CFR is calculated as the ratio between the 7-day average number of deaths and the 7-day average number of cases 10 days earlier
