We introduce a new measure of antigenic distance between influenza A vaccine and circulating strains. The measure correlates well with efficacies of the H3N2 influenza A component of the annual vaccine between 1971 and 2004, as do results of a theory of the immune response to influenza following vaccination. This new measure of antigenic distance is correlated with vaccine efficacy to a greater...
Rapid tests for influenza antigen detection are frequently used, but it is not known how receipt of intranasal influenza vaccine affects results of these tests. We tested healthy adults who received either intranasal or intramuscular influenza vaccine. Of the 14 intranasal vaccine recipients, 7 (50%) had a direct fluorescent antibody test (DFA) result and 2 (14%) had an enzyme immunoassay (EIA)...
BACKGROUND Influenza vaccine composition is reevaluated each year due to the frequency and accumulation of genetic changes that influenza viruses undergo. The beginning of the 2016-2017 influenza surveillance period in Israel has been marked by the dominance of influenza A(H3N2). OBJECTIVES To evaluate the type, subtype, genetic evolution and amino acid substitutions of influenza A(H3N2) viru...
INTRODUCTION Pandemic influenza A H1N1 infections occurred worldwide from 2009. Children were particularly vulnerable. Novel vaccines were used during the pandemic. OBJECTIVE To assess the persistence of antibody to H1N1 influenza 1 year after children aged 6 months to 12 years had been immunised with two doses of either a non-adjuvanted whole-virion H1N1 influenza vaccine or an AS03B-adjuvan...
background and aims: virus-like particles (vlps) have been suggested to be a promising recombinant vaccine approach. several studies have reported that the influenza vlps produced in insect cells is an effective vaccine candidate. due to crucial role of matrix m1 protein in assembly and budding of influenza particles, in all vlps structures, m1 protein have been considered as a main component. ...
Interim Estimates of 2017–18 Seasonal Influenza Vaccine Effectiveness — United States, February 2018
In the United States, annual vaccination against seasonal influenza is recommended for all persons aged ≥6 months (1). 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 report uses data from 4,562 children and adults enrol...
A live attenuated influenza vaccine has been available in Germany since the influenza season 2012/13, which is approved for children aged 2-17 years. Using data from our laboratory-based surveillance system, we described the circulation of influenza and non-influenza respiratory viruses during the influenza season 2012/13 in Saxony-Anhalt. We estimated the effectiveness of live and inactivated ...
We studied anti-influenza cytotoxicity by bulk peripheral blood mononuclear leukocyte (PBL) cultures derived from older, chronically ill volunteers undergoing vaccination. Vaccinees received either cold-recombinant, live-attenuated influenza A/Korea/1/82 (H3N2) virus intranasally or inactivated monovalent influenza A/Taiwan/1/86 (H1N1) subvirion vaccine intramuscularly. PBL were collected pre- ...
High morbidity and mortality of influenza virus infection makes it an important disease world-wide. Mouse is a very well-studied animal model for this disease with similar manifestation to human disease. It would be desirable to induce mucosal as well as circulating immune responses to obtain protection from infection and to decrease the spread of the virus. Cell mediated immunity (proliferativ...
