Hybrid Immunity Improves the Immune Response after the Fourth COVID-19 Vaccine Dose in Individuals with Medical Conditions Predisposing to Severe COVID-19.

Data on immune responses following COVID-19 booster vaccinations and subsequent infections in the immunocompromised are limited. We studied antibody responses after the fourth dose and subsequent infections to define patient groups benefiting most from boosters. Fourth vaccine (booster) doses were, in Finland, first recommended for severely immunocompromised individuals, whom we invited to participate in our study in 2022. We assessed spike protein-specific IgG and neutralizing antibodies (NAb) against the ancestral and Omicron BA.1 strains one month after the fourth dose from 488 adult participants and compared them to the levels of 35 healthy controls after three doses. We used Bayesian generalized linear modeling to assess factors explaining antibody levels and assessed vaccine-induced and hybrid immunity six months after the last vaccine dose. Chronic kidney disease (CKD) and immunosuppressive therapy (IT) were identified as factors explaining sub-optimal antibody responses. The proportion of participants with a normal antibody response and NAbs was significantly lower regarding CKD patients compared to the controls. By the 6-month sampling point, one-third of the participants became infected (documented by serology and/or molecular tests), which notably enhanced antibody levels in most immunocompromised participants. Impaired antibody responses, especially NAbs against the Omicron lineage, suggest limited protection in individuals with CKD and highlight the need for alternative pharmaceutical preventive strategies. Vaccination strategies should take into account the development of robust hybrid immunity responses also among the immunocompromised.

Urinary incontinence associates with poor work ability in middle-aged women: A Northern Finland Birth cohort 1966 study.

INTRODUCTION: Urinary incontinence is a common ailment in women and is likely to affect their work ability. We investigated the associations between the different subtypes of urinary incontinence and several dimensions of perceived work ability in middle-aged general population. MATERIAL AND METHODS: Cross-sectional survey at age 46 among participants of the Northern Finland Birth Cohort 1966 study (n = 3706, response rate 72%). Urinary incontinence symptoms and several items of Work Ability Index were collected by postal questionnaire. Work ability was dichotomized as good or poor work ability in general, in relation to physical job demands, to diseases and own 2-year prospect of work ability. The associations between urinary incontinence and work ability measures were assessed using logistic regression models, with further adjustments for biological, behavioral and work-related factors as well as general health. RESULTS: The odds ratio (OR), from lowest to highest, for poor work ability were 1.4-fold among women with stress urinary incontinence (OR 1.37, 95% confidence interval [CI] 1.09-1.72), 2.5-fold with mixed urinary incontinence (OR 2.51, 95% CI 1.68-3.74) and 3.3-fold with urgency urinary incontinence (OR 3.34, 95% CI 1.95-5.70). We note that our results reflect work ability in a Nordic society. CONCLUSIONS: Especially urgency and mixed types of urinary incontinence are associated with poor work ability among middle-aged women.

Prices of paediatric vaccines in European vaccination programmes.

Objective: To compare the vaccine prices per vaccinated child under 18 and vaccine funding and procurement systems in the national vaccination programmes (NVPs) in Europe. Methods: The on-line survey targeted to NVP managers collected data referred to the information available on 31 December 2016. The prices of vaccines were categorised into three groups. The price per child 1) fully vaccinated comprised all vaccines and doses offered in the NVP; 2) vaccinated with standard vaccines comprised the vaccines included in the NVP in all countries; 3) vaccinated with recent vaccines comprised the pneumococcal conjugate, human papillomavirus and rotavirus vaccines. Results: In the 23 out of 32 countries that answered the survey, 17 funded the vaccines by taxes and six by social insurance. 18 countries procured the vaccines through public tenders or negotiations. Five countries purchased the vaccines by healthcare providers and reimbursed from the health insurance system.In the countries with vaccine procurement through public tenders the price per child vaccinated with standard vaccines ranged from €59 to €117 when using pentavalent and from €98 to €220 when using hexavalent vaccines. The mean price per child vaccinated with recent vaccines was €130 for the countries that offered pneumococcal conjugate and human papillomavirus vaccines and €142 for the countries that in addition included rotavirus vaccine.In the countries that purchased the vaccines by healthcare providers and reimbursed from the health insurance system the price per child vaccinated with standard vaccines ranged from €136 to €427. Conclusions: The vaccine prices differ notably in Europe. Prices were lower in countries where vaccines in the NVP were tax-funded and nationally or regionally procured. Improved procurement systems could lead to substantial savings or possibilities to introduce more vaccines into the NVP.

Decline in varicella cases contacting primary health care after introduction of varicella vaccination in Finland - A population-based register study.

A two-dose varicella vaccination programme at the age of 18 months and 6 years started in September 2017 in Finland with catch-up vaccinations, based on earlier modelling results, for children <12 years (born in 2006 or later) with no history of varicella. Nationwide population-based register data were used to assess the age-specific vaccination coverage and the annual incidence rates of varicella cases contacting public primary health care in 2014-2020. Age-specific incidence rates after (2022) and before (2014-2016) the implementation of the vaccination programme was compared by incidence rate ratios (IRR) with 95 % confidence interval. In 2019-2022, the first-dose coverage of varicella vaccination among children following the routine vaccination programme ranged from 85 to 87 % (children born in 2016 or later). The second-dose coverage was 58 % for the children born in 2016. The coverage of the catch-up vaccinations ranged from 18 % (children born in 2006) to 82 % (children born in 2015) for the first dose and from 10 % to 64 % for the second dose in the respective birth cohorts. In 2022, compared to the pre-vaccination period (2014-2016) the annual incidence rate of varicella cases contacting public primary health care declined in all age groups. The reduction ranged from 92 % to 98 % among the children eligible for the vaccinations (born 2006 or later). The 87 % reduction in the incidence rate among the unvaccinated children < 1 year suggests the indirect effect of the vaccinations. Introducing varicella vaccinations with catch-up was associated with rapid reduction in the varicella cases contacting primary health care in all ages. However, the coverage of the routine programme needs to be improved further as presently susceptibles accumulate and enable thus further outbreaks in coming decades.

Long-term results of a prospective randomized trial comparing tension-free vaginal tape versus transobturator tape in stress urinary incontinence.

INTRODUCTION AND HYPOTHESIS: This study was aimed at investigating the long-term effectiveness of minimally invasive mid-urethral sling (MUS) surgery and at comparing the outcomes between retropubic (tension-free vaginal tape, TVT) and transobturator tape (TOT) methods in the treatment of stress urinary incontinence (SUI) and mixed urinary incontinence (MUI) with a predominant stress component in a long-term follow-up of a randomized controlled trial. METHODS: This work is a long-term follow-up study of a previous prospective randomized trial conducted in the Department of Obstetrics and Gynecology at Oulu University Hospital between January 2004 and November 2006. The original 100 patients were randomized into the TVT (n=50) or TOT (n=50) group. The median follow-up time was 16 years, and the subjective outcomes were evaluated using internationally standardized and validated questionnaires. RESULTS: Long-term follow-up data were obtained from 34 TVT patients and 38 TOT patients. At 16 years after MUS surgery, the UISS significantly decreased from a preoperative score in the TVT (11.88 vs 5.00, p<0.001) and TOT (11.05 vs 4.95, p<0.001) groups, showing a good long-term success of the MUS surgery in both groups. In comparing the TVT and TOT procedures, the subjective cure rates did not differ significantly between the study groups in long-term follow-up according to validated questionnaires. CONCLUSION: Midurethral sling surgery had good long-term outcomes in the treatment of SUI and MUI with a predominant stress component. The subjective outcomes of the TVT and TOT procedures were similar after a 16-year follow-up.

Health care costs related to hepatitis B in Finland are mostly due to chronic infections: a register-based study.

BACKGROUND: Finland is among the countries with low hepatitis B endemicity. We evaluate the hepatitis B-related disease and economic burden needed for evidence-based immunisation policy decision-making. METHODS: Hepatitis B-related cases in 2004-2012 were retrieved from population-based nationwide registers. We evaluated the incidence, health care resource use, health care costs, and life years lost due to hepatitis B-related outcomes. An episode of care was constructed from each individual's hepatitis B-related events retrieved from individually linkable registers. RESULTS: The mean health care costs per an acute hepatitis B case were €450 (SD 240), €2030 (SD 350), and €5400 (SD 3370) in those aged 0-14, 15-64, and ≥65 years, respectively. For chronic infection, the mean cost per case among Finnish-born individuals was €990 and among foreign-born €1360. The costs per case of liver cirrhosis were €15,350 and liver cancer €19,080. In addition, the annual antiviral medication costs per case receiving antiviral medication were €4710 to €5530. Annually <10% of the chronic and approximately 20% of liver cirrhosis cases received antiviral medication. We identified annually 21 acute, 264 chronic, three liver cirrhosis, and four liver cancer cases and 63.7 life years lost due to hepatitis B per 5.3 million inhabitants. The total annual health care costs were €1.2 million of which 60% were antiviral medication costs and 86% accounted for chronic hepatitis B. CONCLUSIONS: When planning prevention of hepatitis B infection, it is pivotal to notice that the overall disease and economic burden due to hepatitis B is mostly due to chronic infection.

Predictors of hospitalisation and death due to SARS-CoV-2 infection in Finland: A population-based register study with implications to vaccinations.

INTRODUCTION: The aim of this study was to investigate how age and underlying medical conditions affect the risk of severe outcomes following SARS-CoV-2 infection and how they should be weighed while prioritising vaccinations against COVID-19. METHODS: This population-based register study includes all SARS-CoV-2 PCR-test-positive cases until 24 Feb 2021, based on the Finnish National Infectious Diseases Register. The cases were linked to other registers to identify presence of predisposing factors and severe outcomes (hospitalisation, intensive care treatment, death). The odds of severe outcomes were compared in those with and without the pre-specified predisposing factors using logistic regression. Furthermore, population-based rates were compared between those with a given predisposing factor and those without any of the specified predisposing factors using negative binomial regression. RESULTS: Age and various comorbidities were found to be predictors of severe COVID-19. Compared to 60-69-year-olds, the odds ratio (OR) of death was 7.1 for 70-79-year-olds, 26.7 for 80-89-year-olds, and 55.8 for ≥ 90-year-olds. Among the 20-69-year-olds, chronic renal disease (OR 9.4), malignant neoplasms (5.8), hematologic malignancy (5.6), chronic pulmonary disease (5.4), and cerebral palsy or other paralytic syndromes (4.6) were strongly associated with COVID-19 mortality; severe disorders of the immune system (8.0), organ or stem cell transplant (7.2), chronic renal disease (6.7), and diseases of myoneural junction and muscle (5.5) were strongly associated with COVID-19 hospitalisation. Type 2 diabetes and asthma, two very common comorbidities, were associated with all three outcomes, with ORs from 2.1 to 4.3. The population-based rate of SARS-CoV-2 infection decreased with age. Taking the 60-69-year-olds as reference, the rate ratio was highest (3.0) for 20-29-year-olds and < 1 for 70-79-year-olds and 80-89-year-olds. CONCLUSION: Comorbidities predispose for severe COVID-19 among younger ages. In vaccine prioritisation both the risk of infection and the risk of severe outcomes, if infected, should be considered.

Information nudges for influenza vaccination: Evidence from a large-scale cluster-randomized controlled trial in Finland.

BACKGROUND: Vaccination is the most effective means of preventing the spread of infectious diseases. Despite the proven benefits of vaccination, vaccine hesitancy keeps many people from getting vaccinated. METHODS AND FINDINGS: We conducted a large-scale cluster randomized controlled trial in Finland to test the effectiveness of centralized written reminders (distributed via mail) on influenza vaccination coverage. The study included the entire older adult population (aged 65 years and above) in 2 culturally and geographically distinct regions with historically low (31.8%, n = 7,398, mean age 75.5 years) and high (57.7%, n = 40,727, mean age 74.0 years) influenza vaccination coverage. The study population was randomized into 3 treatments: (i) no reminder (only in the region with low vaccination coverage); (ii) an individual-benefits reminder, informing recipients about the individual benefits of vaccination; and (iii) an individual- and social-benefits reminder, informing recipients about the additional social benefits of vaccination in the form of herd immunity. There was no control treatment group in the region with high vaccination coverage as general reminders had been sent in previous years. The primary endpoint was a record of influenza vaccination in the Finnish National Vaccination Register during a 5-month follow-up period (from October 18, 2018 to March 18, 2019). Vaccination coverage after the intervention in the region with historically low coverage was 41.8% in the individual-benefits treatment, 38.9% in the individual- and social-benefits treatment and 34.0% in the control treatment group. Vaccination coverage after the intervention in the region with historically high coverage was 59.0% in the individual-benefits treatment and 59.2% in the individual- and social-benefits treatment. The effect of receiving any type of reminder letter in comparison to control treatment group (no reminder) was 6.4 percentage points (95% CI: 3.6 to 9.1, p < 0.001). The effect of reminders was particularly large among individuals with no prior influenza vaccination (8.8 pp, 95% CI: 6.5 to 11.1, p < 0.001). There was a substantial positive effect (5.3 pp, 95% CI: 2.8 to 7.8, p < 0.001) among the most consistently unvaccinated individuals who had not received any type of vaccine during the 9 years prior to the study. There was no difference in influenza vaccination coverage between the individual-benefit reminder and the individual- and social-benefit reminder (region with low vaccination coverage: 2.9 pp, 95% CI: -0.4 to 6.1, p = 0.087, region with high vaccination coverage: 0.2 pp, 95% CI: -1.0 to 1.3, p = 0.724). Study limitations included potential contamination between the treatments due to information spillovers and the lack of control treatment group in the region with high vaccination coverage. CONCLUSIONS: In this study, we found that sending reminders was an effective and scalable intervention strategy to increase vaccination coverage in an older adult population with low vaccination coverage. Communicating the social benefits of vaccinations, in addition to individual benefits, did not enhance vaccination coverage. The effectiveness of letter reminders about the benefits of vaccination to improve influenza vaccination coverage may depend on the prior vaccination history of the population.

Cohort study of Covid-19 vaccine effectiveness among healthcare workers in Finland, December 2020 - October 2021.

Recently, Covid-19 vaccine effectiveness has decreased especially against mild disease due to emergence of the Delta variant and waning protection. In this register-based study among healthcare workers in Finland, the vaccine effectiveness of two-dose mRNA vaccine series against SARS-CoV-2 infection decreased from 82% (95% CI 79-85%) 14-90 days after vaccination to 53% (43-62%) after 6 months. Similar trend was observed for other series. Waning was not observed against Covid-19 hospitalization. These results facilitate decision-making of booster doses for healthcare workers.

Effectiveness of vaccination against SARS-CoV-2 infection and Covid-19 hospitalisation among Finnish elderly and chronically ill-An interim analysis of a nationwide cohort study.

BACKGROUND: In Finland, both mRNA and adenovirus vector (AdV) Covid-19 vaccines have been used after the vaccination campaign started on December 27, 2020. Vaccination of the elderly and chronically ill was prioritized and the interval between doses set to 12 weeks. The objective of this interim analysis was to evaluate first and second dose vaccine effectiveness (VE) in a real-world setting. METHODS: During the first five months of the campaign, a register-based cohort study was conducted in the Finnish elderly aged 70+ years and those aged 16-69 years with medical conditions predisposing to severe Covid-19 (chronically ill). Using Cox regression, VE against SARS-CoV-2 infection and Covid-19 hospitalisation was estimated comparing the hazard in the vaccinated with that in the unvaccinated. RESULTS: The cohorts included 901092 elderly (89% vaccinated) and 774526 chronically ill (69% vaccinated) individuals. Three weeks after the first dose, mRNA VE against infection was 45% (95% confidence interval, 36-53%) and 40% (26-51%) in elderly and chronically ill; mRNA VE against hospitalisation was 63% (49-74%) and 82% (56-93%). In chronically ill, AdV VE was 42% (32-50) and 62% (42-75%) against infection and hospitalisation, respectively. One week after the second dose, mRNA VE against infection was 75% (65-82%) and 77% (65-85%) in elderly and chronically ill; mRNA VE against hospitalisation was 93% (70-98%) and 90% (29-99%). CONCLUSIONS: Covid-19 vaccines protect against SARS-CoV-2 infection and Covid-19 hospitalisation. A single dose provides moderate protection in elderly and chronically ill, although two doses are clearly superior.

National vaccination program - a success story of public health and economy.

The savings in treatment costs generated by disease cases prevented by the national vaccination program exceed the costs of the vaccination program by at least 60 million euros. In addition, other costs due to contracting the illness are avoided. Vaccinations serve the purpose of both increasing well-being and releasing resources for other uses. Financial support of vaccinations through the health insurance system would be costly and targetted to those with the ability to pay. Public funds should be directed to the development of a vaccination program. New vaccines coming on the market are expensive. Adding a new vaccine to the vaccination program is based on scientific evidence-based expert assessments and cost-effectiveness. In addition to preliminary assessments carried out in support of decision-making, the National Institute of Health and Welfare monitors by using population-based health registers the effectiveness and cost-effectiveness of the vaccination program. From the standpoint of transparency of decision-making it would be preferred that the decision-makers define a willingness to pay threshold below which an intervention would be accepted and lead to funding.

Impact of five years of rotavirus vaccination in Finland - And the associated cost savings in secondary healthcare.

INTRODUCTION: This study aimed to estimate the impact of the national rotavirus (RV) vaccination programme, starting 2009, on the total hospital-treated acute gastroenteritis (AGE) and severe RV disease burden in Finland during the first five years of the programme. This study also evaluated the costs saved in secondary healthcare by the RV vaccination programme. METHODS: The RV related outcome definitions were based on ICD10 diagnostic codes recorded in the Care Register for Health Care. Incidences of hospitalised and hospital outpatient cases of AGE (A00-A09, R11) and RVGE (A08.0) were compared prior (1999-2005) and after (2010-2014) the start of the programme among children less than five years of age. RESULTS: The reduction in disease burden in 2014, when all children under five years of age have been eligible for RV vaccination, was 92.9% (95%CI: 91.0%-94.5%) in hospitalised RVGE and 68.5% (66.6%-70.3%) in the total hospitalised AGE among children less than five years of age. For the corresponding hospital outpatient cases, there was a reduction of 91.4% (82.4%-96.6%) in the RVGE incidence, but an increase of 6.3% (2.7%-9.9%) in the AGE incidence. The RV vaccination programme prevented 2206 secondary healthcare AGE cases costing €4.5 million annually. As the RV immunisation costs were €2.3 million, the total net savings just in secondary healthcare costs were €2.2 million, i.e. €33 per vaccinated child. DISCUSSION: The RV vaccination programme clearly controlled the severe, hospital-treated forms of RVGE. The total disease burden is a more valuable end point than mere specifically diagnosed cases as laboratory confirmation practises usually change after vaccine introduction. The RV vaccination programme annually pays for itself at least two times over.

Methods for Health Economic Evaluation of Vaccines and Immunization Decision Frameworks: A Consensus Framework from a European Vaccine Economics Community.

BACKGROUND: Incremental cost-effectiveness and cost-utility analyses [health economic evaluations (HEEs)] of vaccines are routinely considered in decision making on immunization in various industrialized countries. While guidelines advocating more standardization of such HEEs (mainly for curative drugs) exist, several immunization-specific aspects (e.g. indirect effects or discounting approach) are still a subject of debate within the scientific community. OBJECTIVE: The objective of this study was to develop a consensus framework for HEEs of vaccines to support the development of national guidelines in Europe. METHODS: A systematic literature review was conducted to identify prevailing issues related to HEEs of vaccines. Furthermore, European experts in the field of health economics and immunization decision making were nominated and asked to select relevant aspects for discussion. Based on this, a workshop was held with these experts. Aspects on 'mathematical modelling', 'health economics' and 'decision making' were debated in group-work sessions (GWS) to formulate recommendations and/or--if applicable--to state 'pros' and 'contras'. RESULTS: A total of 13 different aspects were identified for modelling and HEE: model selection, time horizon of models, natural disease history, measures of vaccine-induced protection, duration of vaccine-induced protection, indirect effects apart from herd protection, target population, model calibration and validation, handling uncertainty, discounting, health-related quality of life, cost components, and perspectives. For decision making, there were four aspects regarding the purpose and the integration of HEEs of vaccines in decision making as well as the variation of parameters within uncertainty analyses and the reporting of results from HEEs. For each aspect, background information and an expert consensus were formulated. CONCLUSIONS: There was consensus that when HEEs are used to prioritize healthcare funding, this should be done in a consistent way across all interventions, including vaccines. However, proper evaluation of vaccines implies using tools that are not commonly used for therapeutic drugs. Due to the complexity of and uncertainties around vaccination, transparency in the documentation of HEEs and during subsequent decision making is essential.

[Evidence-based cesarean section]. / Tutkimusnäyttöön perustuva keisarileikkaus.

Cesarean delivery is the most frequent major surgery in Finland: in 2013 over 16% of the deliveries were via cesarean route. 27% of the mothers are estimated to face complications. Optimal surgical techniques and other operation-related measures aim to reduce the incidence of complications. Recommendations favor preoperative antibiotics, vaginal preparation, transversal skin incision, non-development of bladder flap, blunt cephalo-caudad uterine extension, spontaneous placental removal, late cord clamping, continuous sutures for uterine closure and subcutaneous skin sutures. Optimal measures will not only reduce complications in cesarean deliveries but bring cost savings and unify the clinical routines and training in specialization programs.

Divergent coverage, frequency and costs of organised and opportunistic Pap testing in Finland.

We evaluated the overall coverage, frequency and costs of Pap testing by screening modality and health care provider in Finland. Information about Pap testing in the Finnish female population of 2.7 million was obtained from nationwide population-based registry data. Among women aged 25-69 years, 87% had had a Pap test taken within or outside the organised programme at least once during the last 5 years and half of those screened in the organised programme had also had at least one Pap test taken outside the programme. Of the annual average of 530,000 Pap tests taken, 84% were taken for screening purposes and 16% as follow-up. Forty percent of the 446,000 annual screening tests were taken in the organised programme, 55% as opportunistic tests in public primary or student health care or by private providers and 5% in public secondary health care. One-fifth of all opportunistic screening Pap tests were taken from women aged <25. The voluminous opportunistic Pap testing in public primary health care was concentrated in young women aged 25-29 whereas the bulk of opportunistic testing in private health occurred in age groups eligible for organised screening. The total cost of all screening Pap tests was €22.4 million, of which 71% incurred in opportunistic screening. Of the 84,000 annual follow-up Pap tests and their €8.3 million total costs, ∼60% incurred in organised screening or in secondary health care.

Impact of vaccination on 14 high-risk HPV type infections: a mathematical modelling approach.

The development of high-risk human papillomavirus (hrHPV) infection to cervical cancer is a complicated process. We considered solely hrHPV infections, thus avoiding the confounding effects of disease progression, screening, and treatments. To analyse hrHPV epidemiology and to estimate the overall impact of vaccination against infections with hrHPVs, we developed a dynamic compartmental transmission model for single and multiple infections with 14 hrHPV types. The infection-related parameters were estimated using population-based sexual behaviour and hrHPV prevalence data from Finland. The analysis disclosed the important role of persistent infections in hrHPV epidemiology, provided further evidence for a significant natural immunity, and demonstrated the dependence of transmission probability estimates on the model structure. The model predicted that vaccinating girls at 80% coverage will result in a 55% reduction in the overall hrHPV prevalence and a higher 65% reduction in the prevalence of persistent hrHPV infections in females. In males, the reduction will be 42% in the hrHPV prevalence solely by the herd effect from the 80% coverage in girls. If such high coverage among girls is not reached, it is still possible to reduce the female hrHPV prevalence indirectly by the herd effect if also boys are included in the vaccination program. On the other hand, any herd effects in older unvaccinated cohorts were minor. Limiting the epidemiological model to infection yielded improved understanding of the hrHPV epidemiology and of mechanisms with which vaccination impacts on hrHPV infections.

The burden and costs of prevention and management of genital disease caused by HPV in women: a population-based registry study in Finland.

The aim of this study was to evaluate the total burden and health care provider costs of prevention, management and treatment of HP-related genital disease outcomes including all organized and opportunistic screening tests. Information about HPV-related disease outcomes in the Finnish female population of 2.7 million was obtained from nationwide population-based registry data. We estimated the incidence, health care resource use, health provider costs and life years lost due to cervical, vaginal and vulvar cancer and intraepithelial neoplasia (CIN, VaIN, VIN), cervical adenocarcinoma in situ, and external genital warts. The average annual disease burden of HPV-related genital disease in the female population of Finland comprises altogether 241 cases of cervical, vaginal and vulvar cancer, 2,898 new cases of CIN, 34,432 cases of minor cytological abnormalities, and almost 4,000 cases of external genital warts. The total annual costs of screening, further diagnostics and treatment of HPV-related genital disease were € 44.7 million of which the annual costs due to cervical cancer screening were € 22.4 million and due to diagnostics, management and treatment of HPV-related genital disease outcomes were € 22.3 million. The latter included € 8.4 million due to minor cervical abnormalities detected by the current cervical screening practice. The extensive opportunistic Pap testing fails to keep the incidence of cervical cancer from increasing among women aged 30-34. In addition opportunistic screening among this and younger age group detects a significant number of cytological abnormalities, most of which are probably treated unnecessarily.

First year experience of rotavirus immunisation programme in Finland.

INTRODUCTION: This study aimed to estimate the impact of rotavirus (RV) immunisation programme on the total hospital treated acute gastroenteritis (AGE) burden, as well as, on severe RV disease burden in Finland during the first year after immunisation programme introduction. Such studies can also be considered as a vaccine-probe-study, where unspecific disease burden prevented by immunisation is assumed to be caused by the agent the vaccine is targeted against. METHODS: The RV related outcome definitions were based on data registered in the National Hospital Discharge Register coded using ICD 10 codes. Incidences of hospitalised and hospital outpatient cases of AGE and RVGE were compared prior (1999-2005) and after (2010) the start of the programme among children under 5 years of age. ICD 10 codes utilised were A00-A09, R11 and K52. RESULTS: The reductions in disease burden, when the post-introduction year was compared to pre-vaccine era, were 80.3% (95% CI 74.5-84.7) in hospital inpatient RVGE among toddlers less than 1 year of age and 53.9% (95% CI 49.8-57.7) when the total inpatient AGE burden was considered in the same age group. For the corresponding hospital outpatient cases the reductions were 78.8% (95% CI 48.4-91.3) and 12.5% (7.1-17.7). The overall vaccine impact against confirmed RVGE in age cohorts eligible for vaccination before the RV season 2010 was 97% (95% CI 90.7-99.0). If the total reductions, both in diagnosed RVGE, as well as in cases without definite microbial diagnosis, were expected to be RVGE, population based estimates for the total disease burden can be obtained: for inpatient RVGE in children less than 1 year of age the estimate is 10.5/1000 pyrs, while the diagnosed specific incidence was less than half of that, 4.9/1000 pyrs. DISCUSSION: During the first post-vaccination year 2010, RV immunisation programme clearly managed to control the severe, hospital treated, forms of RVGE. The total disease burden is a more valuable end point than mere diagnosed cases as laboratory confirmation practises change after vaccine introduction. Our study is limited by the very short post-introduction follow up.

An update to "The cost-effectiveness of rotavirus vaccination: comparative analyses for five European countries and transferability in Europe".

A cost-effectiveness analysis of rotavirus vaccination in Belgium, England and Wales, Finland, France and the Netherlands published in 2009 was updated based on recent studies on rotavirus burden of disease and vaccine efficacy. All the qualitative conclusions in the previous study were found to remain valid. Vaccination remains cost-effective in Finland only when using plausible tender prices.

The cost-effectiveness of rotavirus vaccination: Comparative analyses for five European countries and transferability in Europe.

Cost-effectiveness analyses are usually not directly comparable between countries because of differences in analytical and modelling assumptions. We investigated the cost-effectiveness of rotavirus vaccination in five European Union countries (Belgium, England and Wales, Finland, France and the Netherlands) using a single model, burden of disease estimates supplied by national public health agencies and a subset of common assumptions. Under base case assumptions (vaccination with Rotarix, 3% discount rate, health care provider perspective, no herd immunity and quality of life of one caregiver affected by a rotavirus episode) and a cost-effectiveness threshold of euro30,000, vaccination is likely to be cost effective in Finland only. However, single changes to assumptions may make it cost effective in Belgium and the Netherlands. The estimated threshold price per dose for Rotarix (excluding administration costs) to be cost effective was euro41 in Belgium, euro28 in England and Wales, euro51 in Finland, euro36 in France and euro46 in the Netherlands.
