Before revision: We monitor online conversations of Italian users around vaccineson Twitter, and we provide public access to the on-going data collectionwhich will run continuously throughout the vaccination campaign taking place in Italy . We started collecting tweets matching vaccine-related keywords (in Italian) on December 20th 2020 using Twitter APIs, capturing the Italian vaccine rollout (27th December 2020), and at the time of this writing (13th January 2020) we collected over 1.8 M tweets, with an average number of 30k tweets shared on a daily basis. We report a consistent amount of low-credibility information already circulating on Twitter alongside vaccine-related conversations, whose prevalence is smaller yet comparable to high-credibility information.
After revision: We present VaccinItaly, a project which monitors Italian online conversations around vaccines, on Twitter and Facebook. We describe the ongoing data collection, which follows the SARS-CoV-2 vaccination campaign roll-out in Italy and we provide public access to the data collected. We show results from a preliminary analysis of the spread of low- and high-credibility information.
