Every season, circulating influenza viruses change; therefore, vaccines must be reformulated each year. We aimed to estimate vaccine effectiveness (VE) against severe influenza infection for the 2018/19 season in Italy. We conducted a test-negative design case-control study at five Italian hospitals. We estimated influenza VE against severe acute respiratory infection (SARI) requiring hospitalisation overall, and by virus subtype, vaccine brand, and age. The 2018/19 season was characterised by A(H1N1)pmd09 and A(H3N2) influenza viruses. Vaccine coverage among <18 years recruited SARI cases was very low (3.2%). Seasonal vaccines were moderately effective against type A influenza overall (adjusted VE = 40.5%; 95% confidence interval (CI) = 18.7–56.4%) and subtype A(H1N1)pmd09 viruses (adjusted VE = 55%; 95% CI = 34.5–69.1%), but ineffective against subtype A(H3N2) viruses (adjusted VE = 2.5%; 95% CI = −50.0–36.7%). Both Fluad and Fluarix Tetra vaccines were effective against type A influenza overall and subtype A(H1N1)pdm09 viruses. VE appeared to be similar across age groups (0–64 years, ≥65 years). Seasonal influenza vaccines in the 2018/19 season were moderately effective in preventing SARI caused by A(H1N1)pdm09 influenza but ineffective against A(H3N2).

Abstract Background The burden of influenza and severe acute respiratory infection (SARI) in conflict countries such as Yemen is exacerbated due to limited resources and the collapse of the health system. The aims are to describe epidemiology of SARI, determine influenza detection and case fatality rates among SARI patients. Methods We used a descriptive analytical study design. All SARI patients who meet WHO case definition during 2018-2019 from Sana'a city were included. Nasopharyngeal samples were examined by polymerase chain reaction. A soft copy of data that collected by surveillance staff was obtained from the National Influenza Control Program (NICP). Case fatality rate and detection rate were calculated and P value &lt; 0.05 used for statistical significant. Results 1447 SARI patients were reported: 73% males, 54% aged 15- &lt; 50 years. Comorbidity was among 27% (387) of them: (57% cardio-vascular diseases and 50% diabetes). Samples of 934 (64%) SARI patients were tested and influenza viruses were detected in 141 (15%) patients (13% type A and 2% type B). Higher influenza viruses were detected in winter months (November – February) (17% vs 9%, P &lt; 0.001). Overall SARI fatality rate was 19% (276), significantly higher among patients with comorbidity (26% vs 16%, P &lt; 0.001) confirmed influenza (30% Vs 15%, P value &lt; 0.001) and not receiving antiviral (51% vs 17%, P &lt; 0.001) than relevant groups. Conclusions SARI patients in Yemen had a high case-fatality rate particularly SARI patients with confirmed influenza. Introduce influenza vaccination for the risk group should be considered. Key messages Influenza and SARI cases are high in Yemen and progress to death.

ObjectiveTo estimate the proportion of SARS-CoV-2 and influenza virus coinfection among severe acute respiratory infection (SARI) cases-patients during the first wave of COVID-19 pandemic in Bangladesh.DesignDescriptive study.SettingNine tertiary level hospitals across Bangladesh.ParticipantsPatients admitted as SARI (defined as cases with subjective or measured fever of ≥38 C° and cough with onset within the last 10 days and requiring hospital admission) case-patients.Primary and secondary outcomesProportion of SARS-CoV-2 and influenza virus coinfection and proportion of mortality among SARI case-patients.ResultsWe enrolled 1986 SARI case-patients with a median age: 28 years (IQR: 1.2–53 years), and 67.6% were male. Among them, 285 (14.3%) were infected with SARS-CoV-2; 175 (8.8%) were infected with the influenza virus, and five (0.3%) were coinfected with both viruses. There was a non-appearance of influenza during the usual peak season (May to July) in Bangladesh. SARS-CoV-2 infection was significantly more associated with diabetes (14.0% vs 5.9%, p<0.001) and hypertension (26.7% vs 11.5%, p<0.001). But influenza among SARI case-patients was significantly less associated with diabetes (4.0% vs 7.4%, p=0.047) and hypertension (5.7% vs 14.4%, p=0.001). The proportion of in-hospital deaths among SARS-CoV-2 infected SARI case-patients were higher (10.9% (n=31) vs 4.4% (n=75), p<0.001) than those without SARS-CoV-2 infection; the proportion of postdischarge deaths within 30 days was also higher (9.1% (n=25) vs 4.6% (n=74), p=0.001) among SARS-CoV-2 infected SARI case-patients than those without infection. No in-hospital mortality or postdischarge mortality was registered among the five coinfected SARI case-patients.ConclusionsOur findings suggest that coinfection with SARS-CoV-2 and influenza virus was not very common and had less disease severity considering mortality in Bangladesh. There was no circulating influenza virus during the influenza peak season during the COVID-19 pandemic in 2020. Future studies are warranted for further exploration.
