Many still hesitate to get vaccine, but reluctance is easing

So few people came for COVID-19 vaccinations in one county in North Carolina that hospitals there now allow anyone 16 or older to get a shot, regardless of where they live. Get a shot, get a free doughnut, the governor said.

Alabama, with the country's lowest vaccination rate, launched a campaign to convince people the shots are safe. Doctors and pastors joined the effort.

On the national level, the Biden administration this week launched a “We Can Do This” campaign to encourage holdouts to get vaccinated against the virus that has claimed over 550,000 lives in the U.S.

The race is on to vaccinate as many people as possible, but a significant number of Americans are so far reluctant to get the shots, even in places where they are plentiful. Twenty-five percent of Americans say they probably or definitely will not get vaccinated, according to a new poll from The Associated Press-NORC Center for Public Affairs Research.

They are leery about possible side effects. They tend to be Republican, and they are usually younger and less susceptible to becoming critically ill or dying if they catch COVID-19.
