We monitor online conversations of Italian users around vaccines on Twitter, and we provide public access to the on-going data collection which will run continuously throughout the vaccination campaign  in Italy. We started collecting tweets matching vaccine-related keywords (in Italian) on December 20th 2020 using Twitter APIs, capturing the official start of the Italian vaccination campaign (27th December 2020), and at the time of this writing ( 5th January 2020) we collected over 1.3 M tweets, with over 25k tweets shared on a daily basis. We report a consistent amount of low-credibility information shared on Twitter , whose prevalence is  comparable to high-credibility information with a 1:4 ratio in the number of shared tweets . We believe that our data will allow researchers to understand the interplay between public discourse on online social media and the evolution of the on-going vaccination campaign against SARS-CoV-2 taking place in Italy. An up-to-date collection of tweets will be available here: URL
