Do tell? The only people that I've seen questioning the safety of the vaccine are people like Kantala Harris and other radical dems that have used the virus for political purposes. It only becomes safe after Jan. 20.
Without getting into the association between Trump, Qannon and antivaxers.....I can find some info if you are unaware.
"Even before the announcements made by Pfizer and BioNTech on Nov. 9 and by Moderna on Nov. 16 about the development of highly effective vaccines for COVID-19, Americans were already more willing to get a vaccine than they were in September. The recent increase is primarily due to a
jump in willingness among Democrats."However, Americans overall are still less likely than they were earlier this year to say they'd get a COVID-19 vaccine. Four in 10 remain unwilling to get a vaccine, indicating public health officials face an uphill climb in convincing a good share of the public to do so.
A longer period of development and clinical testing may help to address three of the four most common reasons for hesitancy among those who are unwilling. However, convincing the 12% of Americans who refuse to get a COVID-19 vaccine due to a general distrust of vaccines may prove more difficult."
