Table 2.

Negative topics by mentions.

Topic group	Example mention
Pfizer	“(I am) oddly hesitant to let them inject me. Not sure why but I am positive it has something to do with Trump. I know Pfizer and Moderna refused to take part in Operation Warp Speed, and that's the only reason I will let them blast the stuff into me.”
FDA	“I wasn't going to hesitate taking the new COVID vaccine. But, now that I read the FDA must approve it today under threat of the FDA chief being fired, I'm very much inclined to wait.”
Found vaccine	“A PEW study found that 58% of African-Americans would not take the Covid vaccine. Local leaders in these communities say a lack of trust is the reason.”
Growing hesitancy about vaccines in general	“Mr Rocca said there was a growing hesitancy about vaccines in general, and about a Covid vaccine in particular.”
Federation	“Governments around the world need to combat ‘fake news’ around Covid-19 vaccines which has become ‘a second pandemic’, the International Federation of Red Cross president said.”
Cross	“Francesco Rocca, who works as president of the International Federation of Red Cross and Red Crescent Societies, appeared before the United Nations Correspondents on Monday in a virtual call where he endorsed Orwellian measures to prevent resistance to COVID-19 inoculations.”
Lack of trust	“A new study finds a lack of trust in a #COVID19 vaccine among Black and Latino communities. This sentiment isn't surprising but reflects a long history of mistreatment by the health community.”
Side effects	“I’m reluctant to get the covid vaccine cause it's so new. They don’t even know if a booster would be needed or what long term side effects might be. I would rather they didn’t learn all of that from me.”
COVID-19 vaccine	“Our effort is that everyone in our priority list takes COVID vaccine. We will address the issue of #vaccine hesitancy. But if anyone decides not to take it, we can't force them.”
Public	“Many, if not most, doctors and nurses are thrilled to have a COVID vaccine. But just like the public at large, some healthcare workers have doubts and fears.”
