Question: Paragraph: Vaccination programs against infectious bronchitis virus (IBV) in Egypt depend on both classical and/or imported variant IBV strain vaccines. However, many IBV outbreaks associated with respiratory distress, nephropathy, and high mortalities were attributed to the circulation of both classical and new nephropathogenic IBV variant 2 strains. In the present study, we report the development of attenuated IBV candidate vaccines using the classic IBV strains (IBM41 and IB2) and a nephropathogenic strain (IBvar2). The wild-type (WT) viruses were attenuated through serial passages in embryonated specific pathogen free (SPF) chicken eggs. Virulence of the attenuated viruses was then tested via the ocular route inoculation and the in vivo back passage in day-old SPF chickens. Efficacy against homologous challenge was investigated also in day-old SPF chickens. Results showed that the viruses were successfully adapted to the embryo by the 100th (IBM41 and IB2) and 110th passages (IBvar2). The attenuated viruses were safe and showed no change of virulence in day-old SPF chickens up to the 10th back passages. The efficacy experiment showed that the attenuated vaccines showed 90 to 100% protection against the homologous challenge based on ciliostasis score and protection percent. The att-IBM41 and att-IB2 vaccines were able to reduce the shedding of the challenge at 3 days post-infection (DPI) and no virus shedding was detected in both vaccinated groups by 5 DPI. In the att-IBvar2 vaccinated birds, only 20% of vaccinated birds shed the challenge virus with low titers (10 2.10±0.3 EID 50 /mL) at 3 DPI. In conclusion, the attenuated strains IBM41, IB2, and IBvar2 are efficient vaccine candidates against currently circulating classic and variant IB viruses, respectively. Further studies to evaluate the field efficacy and combining these attenuated IBV strains to induce a wider protection against heterologous IBV challenge are suggested.

Question: Paragraph: Ageing individuals are immunologically characterized by loss of immunological protection and responsiveness, and autoimmunity occurs with increased incidence. Here we review studies on specific age-related changes in B cell generation, activation, and maintenance as well as characteristics of B cell responses and antibody levels during ageing in relation to other cells and factors that are interwoven with B cell biological processes. In the elderly, fewer new B cells are generated, B cell responsiveness to antigens is impaired, and smaller and fewer germinal centers are formed within an immune response with participation of less potent T cells and follicular dendritic cells, leading to the production of reduced, often insufficient plasma cell numbers. Recall responses in the elderly appear to be limited by the cells' proliferative capacity. Hence, vaccine responsiveness is often insufficient and autoantibody production emerges in the elderly. In total, B cells appear to be less affected by age as compared with T cells. Recently, new concepts have been developed to counteract immunosenescence beyond active vaccination, comprising the generation of specific monoclonal antibodies for passive vaccination, immune rejuvenation by immunoablation followed by autologous stem cell transplantation, and modulation of lifestyle.

The aim of this work is to describe the 2017-2018 influenza season and how it affected elderly population in Catalonia despite moderate vaccine coverage among this age group. Methods: Influenza surveillance based on a primary care sentinel surveillance, virological indicators systematic sampling of ILI attended and severe influenza confirmed cases (SHLCI) admitted to hospital. Analysis of data by Chi-squared, ANOVA, multiple regression and negative control test or case to case for vaccine effectiveness assessment in primary care and SHLCI respectively. Results: Moderate-high intensity and early onset season with predominance of influenza B virus (IVB) (63%) followed by an increase of circulation of influenza A virus (IVA). A total of 419 IV from primary care samples. Vaccine effectiveness (VE) in primary care setting was 14% (95%CI: 0-47%). 1306 severe cases (adjusted cumulative incidence 18.54/100,000 inhabitants (95%CI: 17.54-19.55)). The highest proportion of severe cases were in the >64 (65.1%) (aOR 15.70; 95%CI: 12.06-20.46; p < 0.001) followed by 45-64 yo (25.4%) (aOR 6.03; 95%CI: 4.57-7.97). VE in preventing intensive care unit (ICU) admission was 35% (95%CI: 10-54%). Final outcome death while hospitalized occurred in 175 SHLCI cases with a case fatality rate of 13.4%. Conclusions: 2017-2018 influenza season was an unusual epidemic season with an early onset, great predominance of influenza B (Yamagata strain) virus with a high hospitalization rate of severe cases among elderly stressing the need to upgrade vaccine uptake in this age group. Conclusiones: La temporada de gripe 2017-2018 fue una temporada epidémica inusual con un inicio temprano, gran predominio del VGB (cepa Yamagata) con una elevada tasa de hospitalización de casos graves en ancianos, lo que subraya la necesidad de mejorar la aceptación de la vacuna en este grupo de edad.
