A new poll by researchers at the Harvard School of Public Health (HSPH) shows the shortage of H1N1 vaccine for children is easing.

As of late last week, three-quarters of parents who tried to get the vaccine for their children were able to do so. Overall, six in 10 parents have gotten or expect to get their children vaccinated, but more than a third do not. More than half (60 percent) of those parents who do not expect to get the vaccine cite their concerns about the safety of the vaccine as the major reason. The Centers for Disease Control and Prevention considers all children ages 6 months to 18 years a high-priority group for H1N1 vaccination.

The poll, which examines the U.S. public's response to the distribution of H1N1 vaccines this fall, is the seventh in a series on public views concerning the H1N1 flu outbreak undertaken by the Harvard Opinion Research Program at HSPH. The poll was conducted December 16 and 17, 2009.

"Now that the H1N1 vaccine is more widely available, public health officials who want to increase vaccination rates will need to focus more attention on convincing people who most need it of its safety," said Professor Robert Blendon, director of the Harvard Opinion Research Program. "Findings here--like past polls--suggest that beliefs about safety have been difficult to change for a segment of the public."

The poll also found an increase in adult uptake of the vaccine since early November, but 55 percent of adults said they do not intend to get it. "Overall the poll results indicate that even with further efforts from public health officials, many people will not seek the H1N1 vaccine or get vaccinated," said Gillian SteelFisher, research scientist in the HSPH Department of Health Policy and Management and assistant director of the Harvard Opinion Research Program.

This current poll of the U.S. public suggests public concern about the personal risks of H1N1 have declined since a high in September. In September, 52 percent of people said they were concerned they or someone in their immediate family may become sick from H1N1 during the next 12 months; only 40 percent of people said the same in the current December poll.

In November of this year, almost a month after vaccine distribution began, more than three-quarters of respondents (82 percent) said the U.S. was experiencing shortages of the vaccine. In the most recent December poll, about half (52 percent) said this. Asked about shortages in their own community, in November, 60 percent cited a local shortage, whereas in the most recent December poll, only about a third (34 percent) said this.

Parents' experiences appear to mirror their sense that the vaccine shortage is declining. Three-quarters (74 percent) of parents who tried to get the vaccine for their children were able to do so. This means that in total nearly four in 10 parents (38 percent) got the vaccine for their children. These figures compare to the November poll, when only a third of parents (34 percent) who tried to get the vaccine for their children were able to do so, and 14 percent of children older than 6 months in total received the vaccine. (The phrase, "parents" refers to parents of children 6 months and older, except in cases where the term "all parents" is used.)

More than a third of parents (35 percent) do not intend to get the vaccine for their children. The lead reason they give is safety concerns, which is cited by 60 percent of these parents as a "major reason" for their decision. Other factors cited as "major reasons" by parents:

  • They don't think the outbreak is as serious as public health officials once thought (28 percent)
  • They don't believe their child is at risk for a serious case (25 percent)
  • Tthey believe they can get medication to treat H1N1 if their child does get ill (24 percent)

Poll findings indicate that less than a quarter (22 percent) of adults the CDC has indicated should definitely get the H1N1 flu vaccine have received it so far. These high-priority adults include pregnant women, adults with chronic conditions that make them more vulnerable to flu complications, health care and emergency personnel, adults who care for or live with children younger than 6 months of age and young adults ages 18 to 24.

In total, 53 percent of high-priority adults say they have gotten the vaccine (22 percent) or intend to get it (31 percent), while 44 percent do not intend to get the H1N1 vaccine. This group cites these major reasons for not getting the vaccine:
