Optimising assessments of the epidemiological impact in The Netherlands of paediatric immunisation with 13-valent pneumococcal conjugate vaccine using dynamic transmission modelling.

ABSTRACT: This work is the first attempt to quantify the overall effects of a 13-valent pneumococcal conjugate vaccine (PCV13) vaccination programme in the Dutch population taking into account all the direct and indirect effects of the vaccine on invasive pneumococcal disease. Using available Dutch data, a dynamic transmission model for the spread of pneumococci and potential subsequent invasive pneumococcal disease has been adapted to the Dutch setting. Overall, invasive pneumococcal disease cases in the Netherlands are predicted to decrease from a pre-vaccination level of 2623 cases annually to 2475, 2289, 2185, 2179, and 2178 cases annually 5-, 10-, 20-, 30-, and 40-years, respectively, post-vaccination. Therefore, vaccination with PCV13 in the Netherlands is predicted to lower invasive pneumococcal disease cases per year by up to 445 cases in the medium- to long-term. The results are quite robust for the sensitivity analyses performed on the parameters that regulate herd immunity and competition between vaccine and non-vaccine types.

Project description:ObjectiveThe Ministry of Health (MOH), Mongolia, is considering introducing 13-valent pneumococcal conjugate vaccine (PCV13) in its national immunization programme to prevent the burden of disease caused by Streptococcus pneumoniae. This study evaluates the cost-effectiveness and budget impact of introducing PCV13 compared to no PCV vaccination in Mongolia.MethodsThe incremental cost-effectiveness ratio (ICER) of introducing PCV13 compared to no PCV vaccination was assessed using an age-stratified static multiple cohort model. The risk of various clinical presentations of pneumococcal disease (meningitis, pneumonia, non-meningitis non-pneumonia invasive pneumococcal disease and acute otitis media) at all ages for thirty birth cohorts was assessed. The analysis considered both health system and societal perspectives. A 3+0 vaccine schedule and price of US$3.30 per dose was assumed for the baseline scenario based on Gavi, the Vaccine Alliance's advance market commitment tail price.ResultsThe ICER of PCV13 introduction is estimated at US$52 per disability-adjusted life year (DALY) averted (health system perspective), and cost-saving (societal perspective). Although indirect effects of PCV have been well-documented, a conservative scenario that does not consider indirect effects estimated PCV13 introduction to cost US$79 per DALY averted (health system perspective), and US$19 per DALY averted (societal perspective). Vaccination with PCV13 is expected to cost around US$920,000 in 2016, and thereafter US$820,000 every year. The programme is likely to reduce direct disease-related costs to MOH by US$440,000 in the first year, increasing to US$510,000 by 2025.ConclusionIntroducing PCV13 as part of Mongolia's national programme appears to be highly cost-effective when compared to no vaccination and cost-saving from a societal perspective at vaccine purchase prices offered through Gavi. Notwithstanding uncertainties around some parameters, cost-effectiveness of PCV introduction for Mongolia remains robust over a range of conservative scenarios. Availability of high-quality national data would improve future economic analyses for vaccine introduction.

Project description:BackgroundCurrently in Japan, both 23-valent pneumococcal polysaccharide vaccine (PPSV-23) and 13-valent pneumococcal conjugate vaccine (PCV-13) are available for the elderly for the prevention of S. pneumoniae-related diseases. PPSV-23 was approved in 1988, while the extended use of PCV-13 was approved for adults aged 65 and older in June 2014. Despite these two vaccines being available, the recently launched national immunisation programme for the elderly only subsidised PPSV-23. The framework of the current immunisation programme lasts for five years. The elderly population eligible for the subsidised PPSV-23 shot for the 1st year are those aged 65, 70, 75, 80, 85, 90, 95 and ≥ 100. While from the 2nd year to the 5th year, those who will age 65, 70, 75, 80, 85, 90, 95 and 100 will receive the same subsidised shot.MethodsWe performed economic evaluations to (1) evaluate the efficiency of alternative strategies of PPSV-23 single-dose immunisation programme, and (2) investigate the efficiency of PCV-13 inclusion in the list for single-dose pneumococcal vaccine immunisation programme. Three alternative strategies were created in this study, namely: (1) current PPSV-23 strategy, (2) 65 to 80 (as "65-80 PPSV-23 strategy"), and (3) 65 and older (as "≥ 65 PPSV-23 strategy"). We constructed a Markov model depicting the S. pneumoniae-related disease course pathways. The transition probabilities, utility weights to estimate quality adjusted life year (QALY) and disease treatment costs were either calculated or cited from literature. Cost of per shot of vaccine was ¥ 8,116 (US$74; US$1 = ¥ 110) for PPSV-23 and ¥ 10,776 (US$98) for PCV-13. The model runs for 15 years with one year cycle after immunisation. Discounting was at 3%.ResultsCompared to current PPSV-23 strategy, 65-80 PPSV-23 strategy cost less but gained less, while the incremental cost-effectiveness ratios (ICERs) of ≥ 65 PPSV-23 strategy was ¥ 5,025,000 (US$45,682) per QALY gained. PCV-13 inclusion into the list for single-dose subsidy has an ICER of ¥ 377,000 (US$3,427) per QALY gained regardless of the PCV-13 diffusion level. These ICERs were found to be cost-effective since they are lower than the suggested criterion by WHO of three times GDP (¥ 11,000,000 or US$113,636 per QALY gained), which is the benchmark used in judging the cost-effectiveness of an immunisation programmne.ConclusionsThe results suggest that switching current PPSV-23 strategy to ≥ 65 PPSV-23 strategy or including PCV-13 into the list for single-dose subsidy to the elderly in Japan has value for money.
