Insights
Infant rotavirus vaccination with Rotarix is cost-effective in the UK, considering all infections. This vaccination strategy offers value for money from both societal and National Health Service (NHS) perspectives.
Area of Science:
- Public Health
- Health Economics
- Vaccinology
Background:
- Rotavirus infection poses a significant burden on healthcare systems and society.
- Estimating the full economic impact requires considering infections outside of formal healthcare encounters.
- Rotavirus vaccination is a key public health intervention.
Purpose of the Study:
- To evaluate the cost-effectiveness of Rotarix infant rotavirus vaccination in the UK.
- To incorporate community-acquired rotavirus infections into the economic model.
- To assess vaccination from both National Health Service (NHS) and societal perspectives.
Main Methods:
- A lifetime Markov model was developed for a hypothetical UK birth cohort.
- Costs and Quality-Adjusted Life-Years (QALYs) were estimated for vaccinated and unvaccinated scenarios.
- Societal costs included work absence and parental travel; NHS costs included healthcare utilisation.
Main Results:
- The base case cost-effectiveness ratios were £23,298/QALY (NHS perspective) and £11,459/QALY (societal perspective).
- Sensitivity analyses identified hospitalisation costs and GP consultation numbers as key drivers.
- Rotavirus vaccination is projected to be cost-effective within NICE thresholds.
Conclusions:
- Rotavirus vaccination with Rotarix is a cost-effective policy for the UK.
- The inclusion of community rotavirus infections strengthens the economic case for vaccination.
- This supports the integration of Rotarix into the routine paediatric vaccination schedule.
Abstract:
This study estimated the cost-effectiveness of infant rotavirus vaccination with Rotarix in the UK, taking into account community rotavirus infections that do not present to the healthcare system. A Markov model compared the costs and outcomes of vaccination versus no vaccination in a hypothetical birth cohort of children followed over a lifetime, from a societal perspective and the perspective of the National Health Service (NHS). The model estimated costs and quality-adjusted life-years (QALYs) lost due to death, hospitalisation, general practitioner (GP) consultation, emergency attendance and calls to NHS Direct for rotavirus infection in children aged <5 years. Time lost from work and parents' travel costs were also included in the societal perspective. The base case cost-effectiveness ratio for vaccination compared with no vaccination was pound23,298/QALY from the NHS perspective and pound11,459 from the societal perspective. In sensitivity analysis, the most important parameters were hospitalisation cost and number of GP consultations. Addition of Rotarix to the paediatric vaccination schedule would be a cost-effective policy option in the UK at the threshold range ( pound20,000-30,000/QALY) currently adopted by the National Institute for Health and Clinical Excellence.
