Resumo: BACKGROUND: Uptake of influenza vaccination in Canada remains suboptimal despite widespread public funding. To increase access, several provinces have implemented policies permitting pharmacists to administer influenza vaccines in community pharmacies. We examined the impact of such policies on the uptake of seasonal influenza vaccination in Canada. METHODS: We pooled data from the 2007-2014 cycles of the Canadian Community Health Survey ( = 481 526). To determine the impact of influenza va (mais)

Reassortment of high-yield influenza viruses in vero cells and safety assessment as candidate vaccine strains.

Autor(es): Zhou, Jian; Yang, Fan; Yang, Jinghui; Ma, Lei; Cun, Yina; Song, Shaohui; Liao, Guoyang

MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27648636
Resumo: Vaccination is the practiced and accessible measure for preventing influenza infection. Because chicken embryos used for vaccine production have various insufficiencies, more efficient methods are needed. African green monkey kidney (Vero) cells are recommended by the World Health Organization (WHO) as a safe substitute for influenza vaccine production for humans. However, the influenza virus usually had low-yield in Vero cells, which limits the usage of Vero cellular vaccines. This study u (mais)

Sociocultural determinants of anticipated acceptance of pandemic influenza vaccine in Pune, India: a community survey using mixed-methods.

Autor(es): Sundaram, Neisha; Schaetti, Christian; Grize, Leticia; Purohit, Vidula; Joseph, Saju; Schindler, Christian; Kudale, Abhay; Weiss, Mitchell G

MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27658812
Resumo: OBJECTIVES: To investigate community priority and determinants of pandemic influenza vaccine acceptance in Pune, India. Community willingness to accept vaccines is often neglected in pandemic preparedness. Despite an acknowledged need, few such studies have been done in lower income countries. METHODS: A cross-sectional, mixed-methods study used semi-structured explanatory model interviews to assess anticipated acceptance of nasal and injectable vaccines at different prices among 436 urban (mais)

Construction of a recombinant duck enteritis virus vaccine expressing hemagglutinin of H9N2 avian influenza virus and evaluation of its efficacy in ducks.

MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27709401
Resumo: H9 subtype avian influenza viruses (AIVs) remain a significant burden in the poultry industry and are considered to be one of the most likely causes of any new influenza pandemic in humans. As ducks play an important role in the maintenance of H9 viruses in nature, successful control of the spread of H9 AIVs in ducks will have significant beneficial effects on public health. Duck enteritis virus (DEV) may be a promising candidate viral vector for aquatic poultry vaccination. In this study, (mais)

Immunogenicity of trivalent influenza vaccine in patients with lung cancer undergoing anticancer chemotherapy.

MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27820665
Resumo: Lung cancer is a leading cause of cancer-related death, and patients with lung cancer are a priority group for influenza vaccination. However, few studies have assessed the immunogenicity of the influenza vaccine in these patients. Here, we performed a prospective study to evaluate the immunogenicity of the influenza vaccine in patients with lung cancer undergoing anticancer chemotherapy. Twenty-five patients with lung cancer undergoing anticancer chemotherapy and 26 patients with chronic o (mais)

Review of seasonal influenza in Canada: Burden of disease and the cost-effectiveness of quadrivalent inactivated influenza vaccines.

MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27858509
Resumo: In the 2015/16 influenza season, the Canadian National Advisory Committee on Immunization (NACI) recommended vaccination with quadrivalent inactivated influenza vaccine (QIV) for infants aged 6-23 months and trivalent inactivated influenza vaccines (TIVs) or QIVs in adults. The objective of this review (GSK study identifier: HO-13-14054) is to examine the epidemiology and disease burden of influenza in Canada and the economic benefits of vaccination. To inform this review, we performed a s (mais)

Estimating vaccine effectiveness in preventing laboratory-confirmed influenza in outpatient settings in South Africa, 2015.

MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27865064
Resumo: Trivalent seasonal influenza vaccine effectiveness during the 2015 season in South Africa was assessed using a test-negative case control study design. Influenza A(H1N1)pdm09 was the dominant circulating strain. Overall influenza vaccine coverage was 3.2% (29/899). The vaccine effectiveness estimate, against any influenza virus infection, adjusted for age, underlying conditions and timing within season was 46.2% (95% CI: -23.5 to 76.5), and 53.6% (95% CI: -62.6 to 80.3) against influenza A(H1N1)pdm09.

Protection against Streptococcus pneumoniae Invasive Pathogenesis by a Protein-Based Vaccine Is Achieved by Suppression of Nasopharyngeal Bacterial Density during Influenza A Virus Coinfection.

Autor(es): Khan, M Nadeem; Xu, Qingfu; Pichichero, Michael E
Fonte: Infect Immun;85(2)2017 Feb.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27895132
Resumo: An increase in Streptococcus pneumoniae nasopharynx (NP) colonization density during a viral coinfection initiates pathogenesis. To mimic natural S. pneumoniae pathogenesis, we commensally colonized the NPs of adult C57BL/6 mice with S. pneumoniae serotype (ST) 6A or 8 and then coinfected them with mouse-adapted H1N1 influenza A virus (PR/8/34). S. pneumoniae established effective commensal colonization, and influenza virus coinfection caused S. pneumoniae NP density to increase, resulting (mais)

Fonte: Hum Vaccin Immunother;13(4): 895-902, 2017 Apr 03.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 27905835
Resumo: This study aimed to assess the 1-y immunogenicity of influenza vaccines and the association between immunogenicity at 1 m and further influenza infections in children aged 6 m to 18 y. Serum hemagglutination inhibition (HI) antibody titers and GMTs were determined for the recommended influenza strains 0, 1, 6, and 12 m post-vaccination. The serological evidence of influenza infections were defined as the increase of HI titer (HI ≥1:40 and 4-fold rise). The seroprotection rates for str (mais)
