Elizabeth Graves, an ardent supporter of President Donald Trump, is not opposed to vaccines. She said she had taken flu shots and pneumonia shots and, having just turned 50, was interested in being vaccinated against shingles.

But Graves, a legal transcriptionist in Starkville, Mississippi, said she would not be taking a coronavirus vaccine — and the sight of Vice President Mike Pence rolling up his sleeve to get vaccinated on live television on Friday, she added, would not change her mind.

Lawrence Palmer, 51, a field service engineer in Boiling Springs, Pennsylvania, and Brandon Lofgren, 25, who works in his family’s trucking and construction business in rural Wisconsin, said they felt the same way. Both are fans of Trump, and they echoed Graves, who said she was "suspicious” of government and that Pence’s vaccination "doesn’t mean a thing to me.”
