Facebook discussions on Covid-19 Vaccine

A total of 63,396 postings (98% are replies) from 1,311 threads posted between 2 January and 14 March 2021 on a now-deleted public Facebook group, ‘Covid-19 Vaccine Side Effects’. The group was established around December 2020 when vaccination programs first started in various countries, and was terminated at an unknown time in 2021. According to the group profile, it was aimed for users to share their first-hand experience of Covid-19 vaccines, with the group admins regularly reminding users not to post anti-vaccination theories or third-party URLs (e.g., ‘Please Keep complaints about government overreach, or speculation about what vaccinations could do in the future off of this group! This is for personal accounts of vaccinations and the effects it has had on you directly!’).
