Please be careful about spreading misinformation. Vaccines were not widely available until spring of 2021, after the election. Only select few essential healthcare staff were eligible in 2020, and US deliveries began December 14th, 2020.[1] During the 2020 election season you describe it was actually the opponents of President Trump who were encouraging vaccine skepticism.[2]
Thank you for the correction. the resistance to COVID vaccination coincided with its availability. What was killing Trump supporters was his calling the virus media hype and hosting superspreader events, while he and his wife were among the first vaccinated before he left the White House.
