Abstract for: Antivax Movement Under Impact of COVID 19

Mass vaccination has been used as a crucial public health tool to bring diseases under control. The pandemic has created a unique opportunity to understand how attitudes change toward vaccination. By comparing with and without pandemic scenarios, the pandemic indeed increases the perceived risk of disease, and consequently increases the number of Pro Vaccine. However, the rise of vaccine misinformation, which is also amplified by social media filter bubbles, increases the perceived risk of vaccines, leading to a higher tendency of Undecided Individuals' becoming Antivaxxers. On the other hand, the new COVID-19 Recovered Individuals (with severe symptoms) may turn into Pro Vaccine, depletes the Undecided Individual and Antivaxxers number. To conclude, a competition emerges between Pro Vaccine and Antivaxxers in persuading Undecided Individuals to their sides, respectively. The short-term policy includes targeted and straightforward information to clarify Undecided Individuals' concerns, instead of the usual fact-based information. Long-term policy focuses on tackling misinformation from being amplified in social media filter bubbles, improving science and risk communication.
