Understand

Over 12 billion doses of COVID-19 vaccines have been administered at the time of writing.

• However, public perceptions of vaccines have been complex.
• We analyzed COVID-19 vaccine-related tweets to understand the evolving perceptions of COVID-19 vaccines.
• We finetuned a deep learning classifier using a state-of-the-art model, XLNet, to detect each tweet's sentiment automatically.
