Mettenleiter, Jürgen StechAbstractInfluenza A viruses (IAV) have caused seasonal epidemics and severe pandemics in humans. Novel pandemic strains as in 2009 may emerge from pigs, serving as perpetual virus reservoir. However, reliably effective vaccination has remained a key issue for humans and swine. Here, we generated a novel double-attenuated inf...

(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. ...

The flu season is up and running in the Northern Hemisphere, and early signs in both the United States and Europe are that the effects might not be quite as severe as the brutal 2017/18 season. The United States is predominantly seeing H1N1 circulating, while monitoring in Europe has identified co-circulation of H1N1 and H3N2—both varieties of Influenza A that should be covered by the seasonable vaccine. What if they weren’t though? Influenza A can be found in both human and animal populations, and it evolves rapidly through genetic mutation. Each year many humans rely on their country&a...

CONCLUSION: The intranasal inactivated influenza vaccine is generally safe, and the LTh(αK)-adjuvanted vaccine is more immunogenic than non-adjuvanted control vaccine. ClinicalTrials.gov Identifier: NCT03293732. PMID: 30837170 [PubMed - as supplied by publisher]

Abstract In the United States, annual vaccination against seasonal influenza is recommended for all persons aged ≥6 months (https://www.cdc.gov/flu/protect/whoshouldvax.htm). Effectiveness of seasonal influenza vaccine varies by season. During each influenza season since 2004-05, CDC has estimated the effectiveness of seasonal influenza vaccine to prevent laboratory-confirmed influenza associated with medically attended acute respiratory illness (ARI). This interim report uses data from 3,254 children and adults enrolled in the U.S. Influenza Vaccine Effectiveness Network (U.S. Flu VE Network) during November 2...

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...

By Susan Scutti, CNN (CNN) — Don’t let your guard down: The US flu season is expected to continue for several more weeks, with activity across the nation now elevated, the US Centers for Disease Control and Prevention reported Thursday. A flu shot is still recommended for those who have neglected to get one, but the CDC estimated this year’s vaccine’s overall effectiveness in preventing an infection at just 47%. The shot’s success varies based on your age, the CDC noted. Among children up to 17, its overall effectiveness against flu was 61%, while just 24% of adults 50 and older who received t...

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...
