A new CBS poll has found that seven out of 10 Americans consider H1N1 virus a 'very' or 'somewhat' serious problem.
In May, just 49 percent described H1N1 as "very" or "somewhat" serious. The percentage of Americans who say swine flu, is a "very serious" problem has more than doubled since May, rising from 12 percent to 28 percent.
Just twenty-one percent of Americans now think that H1N1 is "not too serious" in comparison to last May's 35 percent.
Forty-five percent of parents with kids under 18 say they are "very likely" to have their kids vaccinated, and another 22 percent are "somewhat likely" to do so.
Another 31 percent say they are "not very" or "not at all" likely to have their children vaccinated.
Older Americans are particularly concerned about H1N1, despite some evidence that younger people may be more susceptible to the virus.
Eighty-two percent of those 65 or older describe the outbreak as serious.
Women are slightly more likely than men to view it as serious.
