Introduction. Influenza is a widespread acute respiratory disease and represents a serious Public Health problem, both from the NHS and society perspectives. The High Dose quadrivalent influenza vaccine (QIV HD) is a flu vaccine containing 4 times the antigens of a Standard Dose vaccine, resulting in demonstrated superior protection in the population aged 65 years and over.
Methods. The analysis has been conducted from the perspective of the NHS. The CEA focuses on the comparison between QIV HD and the QIV SD vaccine. The BIM aims to estimate the potential economic impact for the National Health Service (NHS) resulting from the use of QIV HD in clinical practice in subjects aged 65 or over, when considering its introduction in combination with currently used vaccines, QIV SD and adjuvanted TIV.
Results. In a scenario which considers hospitalizations possibly related to influenza, so including cardio-respiratory events, a dominant cost-effectiveness profile emerges in the comparison with QIV SD. In terms of budget impact, overall savings obtained by comparing the two scenarios regarding hospitalizations are equal to 92,766,429 € over the three years’ time horizon considered in the analysis.
Conclusions. Nowadays, also considering the state of emergency due to the spread of the SARS-CoV-2 virus, it is crucial to implement innovative health technologies that improve the efficiency and sustainability of the health system. Also, it is essential to protect the elderly population, helping to avoid overload and healthcare systems disruption due to the many COVID-19 hospitalizations.
