Health care workers and those who care for young children are refusing flu shots at a considerable rate with 28 percent saying they would not get vaccinated, according to a recently released poll by Consumer Reports.

The survey polled 1,500 American adults via telephone. Participants were divided into subsections, one of which was the “work risk” category, comprising people who work in health care environments and care for young children.

Overall, adults were split over whether to get a flu shot or not: 37 percent of adults polled said they would definitely get vaccinated, and 30 percent said they would definitely not get the vaccine. 31 percent were unsure, the press release noted.

Less than half of participants considered “at risk” of infection, including those with lung, heart, immune system, or neurological conditions, said they would get the flu vaccine. 51 percent of poll participants aged 65 and older said they would do the same.

Among all adults who said they would not get a flu shot, the leading reasons for avoiding a vaccine included belief that the effects of a flu outbreak are exaggerated (45 percent), concern over the vaccine’s side effects (44 percent), and concern over the vaccine’s safety (41 percent).
