Most US Adults Have Not Gotten A Flu Shot For This Mild Season

(CNN) — Most US adults have not gotten a flu shot this season, according to a new survey from NORC, a research organization at the University of Chicago. As of mid-November, only 43% of surveyed people 18 or older said they had gotten vaccinated against the flu, according to NORC, which has conducted the National Immunization Survey for the US Centers for Disease Control and Prevention since 2005. Another 14% who remain unvaccinated claim that they will get the shot, the survey indicates. Even if they do as they intend, that leaves considerably more than a third of adults (41%) who have not — and will not — get a flu shot, according to NORC. (The remaining 2% either did not answer or responded, “I don’t know.”) The report comes early in what has been a mild season. Thirty-eight states, the District of Columbia and Puerto Rico experienced minimal flu activity for the week ending December 1, while New York City and 10 states experienced low or moderate activity, according to Friday’s weekly flu report from the CDC. Only two states, Georgia and Louisiana, experienced high activity during the week. The mild season is a dramatic shift from the previous flu season, which was the deadliest in decades, with more than 80,000 flu-related deaths in the United States. ‘It’s still very, very early’ “We cannot claim that the 43% of vaccinated people is the reason for the mild flu season so far,” said Richard Webby, a f...

CONCLUSIONS: Influenza-associated mortality was substantial during this period, especially in the elderly. By subtype, influenza A(H3N2) virus made the largest contribution to influenza-associated mortality. PMID: 31588700 [PubMed - in process]

Abstract Influenza virus is activated by proteolytic cleavage of hemagglutinin by trypsin. After determining the optimal trypsin concentration, intracellular and extracellular influenza A/PR/8/34 (H1N1) and A/Victoria/361/2011 (H3N2) virus productions were compared in cultures treated with T-705 (favipiravir) and GS 4071 (an active form of oseltamivir). Although both drugs efficiently inhibited extracellular viral RNA release in a dose-dependent manner, T-705 inhibited it to the level of the inoculum without trypsin treatment, while GS 4071 inhibited it to a final level 10 times higher than that without trypsin. T...

Conclusions: Human challenge studies and systems biology approaches are important tools that should be used in concert to advance our understanding of influenza infection and provide targets for novel therapeutics and immunizations. Introduction Although influenza virus was recognized as an important pathogen over a century ago, influenza continues to cause a significant burden of disease. In the United States alone, it's estimated that in the 2017–2018 season there were 959,000 hospitalizations related to influenza illness, and 79,400 deaths (CDC, 2018). Worldwide, WHO estimates that annual influenza...

(CNN) — Flu activity remains high across the nation, and there’s a second wave of severe infections striking some states. There were as many as 26.3 million flu illnesses, 12.4 million medical visits and 347,000 flu hospitalizations between October 1 and March 2, according to the weekly flu report released Friday by the US Centers for Disease Control and Prevention. “We’re still having flu. And we’re still seeing a steady stream of patients who are being admitted to hospital with influenza,” said Dr. William Schaffner, medical director of the National Foundation for Infectious Diseases. ...

Abstract CDC collects, compiles, and analyzes data on influenza activity and viruses in the United States. During September 30, 2018-February 2, 2019,* influenza activity† in the United States was low during October and November, increased in late December, and remained elevated through early February. As of February 2, 2019, this has been a low-severity influenza season (1), with a lower percentage of outpatient visits for influenza-like illness (ILI), lower rates of hospitalization, and fewer deaths attributed to pneumonia and influenza, compared with recent seasons. Influenza-associated hospitalization r...

The 2018-2019 flu season has been a relatively mild one — and a pretty effective flu shot is part of the reason why. Mid-season estimates suggest that the flu shot has reduced the risk of illness by around 47% in vaccinated people, according to a report from the Centers for Disease Control and Prevention (CDC) released Thursday. During the severe 2017-2018 flu season, vaccine efficacy was estimated at just 36%. The difference is partly because the dominant influenza virus last year, H3N2, is known to cause more serious illnesses and to be less responsive to vaccination than other strains. This year, H1N1 — whic...

AbstractWe evaluated the anti-influenza-virus effects ofMelia components and discuss the utility of these components. The effects of leaf components ofMelia azedarach L. on viruses were examined, and plaque inhibition tests were performed. Thein vivo efficacy ofM. azedarach L. was tested in a mouse model. Leaf components ofMelia azedarach L. markedly inhibited the growth of various influenza viruses. In an initial screening, multiplication and haemagglutination (HA) activities of H1N1, H3N2, H5, and B influenza viruses were inactivated by the liquid extract of leaves ofM. azedarach L. (MLE). Furthermore, plaque inhibition ...
