We introduce a new method of analyzing the potential of Twitter’s impact on vaccine hesitancy. We create bots that significantly differ in the initial seed set of followed accounts. Each seed set has varying percentages of vaccine skeptics and vaccine advocates. We allow our bots to access Twitter’s timeline a few times a day. If the bot reads any tweet related to COVID-19 vaccines, it will follow the author of the tweet. After the end of the experiments, we carefully examine the profile of tweets observed during the experiment.
