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...

In this study, we investigated the protective effect of an attenuated bacterial outer membrane vesicle ­harboring modified lipid A moiety of lipopolysaccharide (fmOMV) against IAV infection and the underlying mechanisms. Administration of fmOMV conferred significant protection against a lethal dose of pandemic H1N1, PR8, H5N2, and highly pathogenic H5N1 viruses; this broad antiviral activity was dep endent on macrophages but independent of neutrophils. fmOMV induced recruitment and activation of macrophages and elicited type I IFNs. Intriguingly, fmOMV showed a more significant protective effect than other TLR ligands ...

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]

Y, Reichl U Abstract A cultivation strategy to increase the productivity of Modified Vaccinia Ankara (MVA) virus in high-cell density processes is presented. Based on an approach developed in shake flask cultures, this strategy was established in benchtop bioreactors, comprising the growth of suspension AGE1.CR.pIX cells to high cell densities in a chemically defined medium before infection with the MVA-CR19 virus strain. First, a perfusion regime was established to optimize the cell growth phase. Second, a fed-batch regime was chosen for the initial infection phase to facilitate virus uptake and cell-to-cell spre...

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...
