Changes in influenza viruses require regular reformulation of strain-specific influenza vaccines. Vaccines based on conserved antigens provide broader protection. Influenza matrix protein 2 (M2) is highly conserved across influenza A subtypes. To evaluate its efficacy as a vaccine candidate, we vaccinated mice with M2 peptide of a widely shared consensus sequence. This vaccination induced antib...
A quantitative study of the antigenicity of various vaccines containing influenza A virus has been made in human beings. A complex vaccine prepared from chick embryos inoculated with both influenza A virus and the X strain of canine distemper virus was found to be more effective than other vaccines in stimulating the production of neutralizing antibodies against the former virus. The increased ...
BACKGROUND Influenza virus remains a significant health and social concern in part because of newly emerging strains, such as avian H5N1 virus. We have developed a prototype H5N1 vaccine using a recombinant, replication-competent Adenovirus serotype 4 (Ad4) vector, derived from the U.S. military Ad4 vaccine strain, to express the hemagglutinin (HA) gene from A/Vietnam/1194/2004 influenza virus ...
background: to assess the frequency and type of adverse events after influenza vaccination in iranian adults. methods: health care workers in 7 medical centers received the influenza vaccine from october 2006 to february 2007 and followed by phone regarding symptoms experienced after vaccination. results: of 897 adults who participated in the study, local and systemic reactions were reported b...
BACKGROUND The ectodomain of matrix protein 2 (M2e) of influenza A virus is a rationale target antigen candidate for the development of a universal vaccine against influenza as M2e undergoes little sequence variation amongst human influenza A strains. Vaccine-induced M2e-specific antibodies (Abs) have been shown to display significant cross-protective activity in animal models. M2e-based vaccin...
The development of novel human vaccines would be greatly facilitated by the development of in vivo models that permit preclinical analysis of human immune responses. Here, we show that nonobese diabetic severe combined immunodeficiency (NOD/SCID) beta(2) microglobulin(-/-) mice, engrafted with human CD34+ hematopoietic progenitors and further reconstituted with T cells, can mount specific immun...
BACKGROUND Influenza virus is a major infectious pathogen of the respiratory system causing a high degree of morbidity and mortality annually. The worldwide vaccines are decided and produced annually by World Health Organization and licensed companies based on the samples collected from all over the world. The aim of this study was to determine phylogenecity and heterogenecity of the circulatin...
Correlates of 2009 H1N1 influenza vaccine acceptability among parents and their adolescent children.
School-aged children were a priority group for receipt of the pandemic (2009) H1N1 influenza vaccine. Both parental and adolescent attitudes likely influence vaccination behaviors. Data were collected from surveys distributed to middle- and high-school students and their parents in two counties in rural Georgia. Multivariable logistic regression analyses were conducted to assess correlates of p...
BACKGROUND Influenza has an important public health impact worldwide with its considerable annual morbidity among persons with or without risk factors and its serious complications among persons in high-risk groups. The seasonal influenza vaccine is essential for preventing the burden of influenza in a population. Since the vaccine is reformulated each season according to the virus serotypes in...
In the present study, we assessed the incidence of adverse events and influenza-like symptoms in a working population in Switzerland that was vaccinated against influenza. A total of 12,582 individuals of working age (<65 years old) were offered a free influenza vaccine of their choice (injectable or intranasal vaccine) in October and November 2000. Of these individuals, 1600 were vaccinated ag...
