COVID-19 vaccine

The Wikipedia article on COVID-19 vaccine has been edited 5,672 times since it was created in 2020, by 895 distinct accounts and IP addresses. That averages about 879 recorded changes a year, or several every day, which puts it among the more actively maintained pages on the encyclopedia.

Within the revisions retrieved for this report, the ten busiest contributors account for about 60% of the changes. Editing that concentrated usually means a small group of regulars is doing the maintenance, which tends to produce consistent wording — and also means the page reflects a narrow set of contributors. In the same window, about 13% of the retrieved revisions came from bot accounts, which handle routine work such as link repair and reference formatting.

Within the retrieved window, 2023 carries the most recorded activity, with 137 changes. 14 of those revisions fall in the last 90 days. The most recent recorded edit was 29 days ago.

This report is built from the 500 most recent revisions retrieved from Wikipedia, about 9% of the 5,672 recorded edits. Figures drawn from that window describe the window only, and the report cannot establish why a change was made or whether it was correct.
