Project description

Our research group has been monitoring tweets related to COVID-19 vaccines since November 2020. This website is a constantly updated dashboard to visualize what the crowd is talking about and what pieces of information are being shared. Data collection ended on July 12, 2023.

Why is it relevant?

With the recent approval of COVID-19 vaccines, a large debate about safety has emerged on social media. Positions in favor and against the vaccines have fueled such a discussion with arguments that are often based on unreliable sources, when not on fake news.

Where in the World

Which countries are tweeting about COVID-19 vaccines?

not present
infrequent
very frequent

This map shows from which countries people are tweeting about COVID-19 vaccines. The project is currently analyzing only tweets written in English, so it is normal that more English-speaking states are highlighted. Darker colours mean a higher concentration of tweets.


This Week in Hashtags

What were the most tweeted hashtags in the last 7 days?

Here is a glance at the hottest hashtags when it comes to tweets about COVID-19 vaccines. The larger and darker the rectangle is, the more the hashtag was tweeted.

Most shared Web Pages and Websites

What sources of information have people used in the last week?

What are the sources from which people get their information? This is an issue that in recent years has reached high importance given the significant increase in fake news and misleading information.

Here we highlight the most popular URLs shared in the last week by tweets mentioning COVID-19 vaccines.

Through a constantly updated classification we can monitor the domains that have been tweeted the most, which are the websites from which the users recover information about the vaccines.


Symptom Discussed by the Users

What possible symptoms are being discussed?

What symptoms or medical terms are mentioned when people tweet about COVID-19 vaccines? This Word Cloud shows what the people of Twitter have focused since we started monitoring it.

The algorithm that this module is based on has been developed by the same research group and has been recently published in two of the most important conferences in the field of Artificial Intelligence and Natural Language Processing: EACL 2021 and W3PHIAI (Best Short Paper - sponsored by IBM), workshop co-located with AAAI 2021.
