States utilized a range of tools to manage infectious-disease outbreaks, including vaccination rules, incentives, and communication strategies. This database includes online publications from state governors and departments of health across all 50 U.S. states and the District of Columbia. It spans from December 2020, when Phase 1a of the COVID-19 vaccination allocation began, to September 2021, when vaccines were widely available and often mandated. In total, 5,223 unique publications were collected, each classified by type: Flyer, Milestone, Info, and Policy. We also address key considerations for analyzing this data and suggest potential research questions that can be explored with it.<\/jats:p>","DOI":"10.1038\/s41597-026-06975-0","type":"journal-article","created":{"date-parts":[[2026,3,20]],"date-time":"2026-03-20T06:56:33Z","timestamp":1773989793000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["COVID Diaries, State Response to COVID Vaccination Program, December 2020 to September 2021"],"prefix":"10.1038","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8109-6723","authenticated-orcid":false,"given":"Avalon S.","family":"Moore","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bridget","family":"Vitu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felicia","family":"Fraizer-Bisner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter J.","family":"Williams","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucy","family":"van der Merwe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdelrhman","family":"Gouda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dessislava","family":"Kirilova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2117-9321","authenticated-orcid":false,"given":"Christopher","family":"Pittenger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helen","family":"Pushkarskaya","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,3,20]]},"reference":[{"key":"6975_CR1","unstructured":"Centers for Disease Control and Prevention.
