NEW YORK (CNN) – According to a recent survey by NORC, a research organization at the University of Chicago, most US adults did not receive flu this season.
There were only 43 percent in mid-November According to NORC, which has been conducting the National Immunization Survey for the US Centers for Disease Control and Prevention since 2005, they said they had been vaccinated against the flu. Another 14 percent of respondents say they would get the vaccine shot, the poll shows.
Even if they do what they intend to do, NORC says that well over a third of adults (41 percent) are left who have not or will not get a flu shot. (The remaining 2 percent either did not answer or responded, "I do not know.")
The report comes early in a mild season. Thirty-eight states, the District of Columbia and Puerto Rico, experienced minimal flu activity during the week leading up to December 1
The mild season is a dramatic shift from the previous flu season, which has been the deadliest for decades, with more than 80,000 flu deaths in the United States
"We can not claim that the 43% of vaccinated people in the United States Reason for the mild flu season, "said Richard Webby, a flu scientist and adviser to the World Health Organization, on recommendations for the composition of flu vaccines. Webby, who was not involved in the NORC survey, said the vaccination rates are similar to those of years when the flu effect was widespread and severe in many people.
"We have to keep in mind that it's still very, very early, and even at this time last year, not much has been done," said Webby, a member of the St. Jude Children's Division of Infectious Diseases. s Research Hospital.
Result of flu during the week that ended on December 1, although five children died earlier this season, the CDC reported. In adults, flu deaths from pneumonia and other flu-related illnesses are estimated. The proportion of deaths from pneumonia and the flu was below the usual threshold for this season, the CDC said.
Among those who attended a doctor's office, only 2.2 percent said the reason for their visit was a flu-like illness; According to the CDC, this is the normal rate for this season.
The report also showed a total of 383 hospitalizations reported since October 1, with slightly more than one flu-related hospital treatment per 100,000 people during the week ended December 1. The highest hospitalizations were in adults over 65 years and children under 4 years old. In both age groups, there were just over 3 flu hospitalizations per 100,000 people.
Webby said a "reassuring signal" this year is that the H1N1 strain is the predominant strain of the flu.
"That's the strain a bit better to match our vaccine," he said. "It does not usually have the same impact as in the H3N2 season, and we did that last year." Influenza B viruses, which have the same symptoms as A viruses, circulate as usual this season, according to the CDC.
In the week ending December 1, there were 1,105 new laboratory-confirmed cases on 6,170 calculated by the CDC. These numbers do not include all persons who are infected with the flu, as many people do not seek medical help in case of illness and therefore remain uncounted.
The main response to seasonal flu is 6 months or older for anyone to get vaccinated, according to the CDC. As long as flu is circulating in the area where you live, it is not too late to get vaccinated.
Webby is worried about "the quarter of over 60 no longer living people" given the new NORC report. "Adults over the age of 65, children under 2 years old, and people with discomfort should not only get a flu shot but also a pneumococcal vaccine to prevent pneumonia, the CDC says." Flu is more severe or even fatal in these groups than in healthy adults
About half of people in the 18-44 age group have not been on flu, Webby notes, believing it is likely to be a tough fight, "trying to increase vaccination coverage. Influenza infections usually do not cause any serious illness in this age group.
"We fight a bit because the flu is not really a deadly disease, which we know of course," he said. "Maybe healthy adults have a relatively low risk of getting a very serious flu infection, but if they become infected, they may still infect others, and how many people in this age group have young children or older parents?"
Older people are at a higher risk of getting a serious illness. Webby said, "If you get yourself vaccinated, you protect yourself not just by yourself, but also by herd immunity."
The overall effectiveness of last year's flu shot was estimated at 40 percent, meaning that the vaccine puts a person at risk of receiving medical help claim, according to CDC has reduced by 40 percent. In children, efficacy rates were higher: in children who shot, 59 percent sought medical help for the virus, the CDC reported this year.
Although the vaccine is incomplete, it reduces the severity and duration of symptoms and those who do so after receiving a vaccine require less chance of hospitalization and also die less frequently.
Webby added that the vaccine is safe too. Although some people report a painful arm after the shot, the overwhelming majority do not experience any extreme side effects.
"The vaccine has been given to many people each year with a very good safety record," he said.
