Historical data on COVID-19 vaccination doses administered in Germany, per state.

COVID-19 vaccination doses administered in Germany, per state

The year is 2021. The RKI is sharing vaccination statistics through an Excel spreadsheet. The spreadsheet only contains detailed data for a single day at a time — meaning historical data is lost every time the sheet gets updated.

This repository aims to…

1. extract the data into CSV for easier machine-readability
2. pull in hourly, automated updates
3. preserve the historical data for each German state
4. visualize the data with charts

As of 2021-02-11, this repository also provides data on vaccine orders being delivered into Germany.

CSV details

pubDate vs. date

The CSV contains two date columns:

• pubDate refers to the “last modified” date of the source sheet, as found in the Excel file’s metadata.
• date refers to the date of the vaccination statistics, as listed in the Excel sheet’s contents.

Usually, the spreadsheets containing the statistics for day X are published on day X + 1, but there have been exceptions where the stats got published on the same day. In case multiple spreadsheets are released containing data for the same date, we only consider the latest version.

initialDoses* vs. finalDoses*

• Any columns with the initialDoses prefix refer exclusively to first doses of vaccines that require two doses in total (i.e. Pfizer/BioNTech, Moderna, or AstraZeneca).
• Any columns with the finalDoses prefix refer exclusively to
  • second doses of vaccines that require two doses in total (i.e. Pfizer/BioNTech, Moderna, or AstraZeneca), and
  • doses of vaccines that only require a single dose (i.e. Johnson & Johnson).

Partially vs. fully vaccinated

There’s been some confusion about what “partial” vaccination means. Given that there are multiple potentially interesting metrics that RKI does not report directly, we derive and expose the following additional columns:

• onlyPartiallyVaccinatedCumulative: the number of people who are partially vaccinated but still need a second shot. (They received exactly 1 dose of Pfizer/BioNTech, Moderna, AstraZeneca, and still need a second dose to become fully vaccinated.)
• onlyPartiallyVaccinatedPercent
• atLeastPartiallyVaccinatedCumulative: the number of people who received at least one vaccination. (They received at least 1 dose of Pfizer/BioNTech, Moderna, AstraZeneca, or Johnson & Johnson. This includes people who received 2 doses of Pfizer/BioNTech, Moderna, or AstraZeneca.)
• atLeastPartiallyVaccinatedPercent
• fullyVaccinatedCumulative: the number of people who received either 1 dose of Johnson & Johnson; or 2 doses of Pfizer/BioNTech, Moderna, or AstraZeneca.
• fullyVaccinatedPercent

Deprecated columns

As of 2021-04-08, RKI stopped reporting the following data points:

• initialDosesDueToAge
• initialDosesDueToProfession
• initialDosesDueToMedicalReasons
• initialDosesToNursingHomeResidents
• finalDosesDueToAge
• finalDosesDueToProfession
• finalDosesDueToMedicalReasons
• finalDosesToNursingHomeResidents

These columns are still included in the CSV as they contain potentially useful data for prior dates.

Anomalies in the data

Cumulative vaccination metrics cannot decrease over time, yet sometimes the reported data contains such a “drop” (as reflected in the charts). These anomalies match the data reported by the RKI, which sometimes overreports statistics and then corrects the numbers for the next day, or vice versa. (Sadly, the RKI doesn’t publish corrected numbers for the previous day, else we could retroactively correct our data.)

This repository complements the incredible owid/covid-19-data project, which includes vaccination data for Germany as a whole, but not for individual German states. The sociepy/covid19-vaccination-subnational project offers a global collection of regional vaccination data, and relies on our data (❤️).
