Rationale

The COVID-19 vaccine has been shown to be effective in preventing COVID-19 infections and reducing the transmission of the virus.

Definition

This metric shows the daily percentage uptake of booster vaccinations given as part of the spring booster campaign in 2023. Data is shown by vaccination date.

Methodology

Vaccinations carried out in England are reported in the National Immunisation Management Service (NIMS). This is the system of record for the vaccination programme in England, including both hospital hubs and local vaccination services. Data are extracted at midnight on the date of report. Geographic locations of vaccinations are based on where the people who were vaccinated live, and not where the vaccination was given. Vaccinations to England residents that were given outside of England are included if they have been recorded in NIMS. Only people who have an NHS number and are currently alive are included. Age is defined as a person's age at the time the data were extracted. This metric shows the daily total percentage uptake of spring booster 2023 vaccinations and is calculated as the total number of spring booster 2023 vaccinations given to people aged 75 years and over, divided by the number of people who are currently aged 75 years and over.

Caveats

It is possible that the number of people vaccinated may reduce over time, due to people dying or moving out of a resident population. People who are eligible for a spring booster vaccination but are less than 75 years old (e.g. immunocompromised individuals) are not included in the count.
