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.

Time and labour costs of preventive health care, including vaccinations, in Finnish child health clinics.

In Finland all children are entitled to regular health check-up visits at child health clinics (CHC). During the visits public health nurses and physicians follow-up the growth and development of the child, evaluate the welfare of the family, give health counselling and vaccinate the children. The aim of this study was to measure the time used by the nurses and physicians for different tasks during the visits and evaluate the costs of preventive health care procedures.

Understanding coronavirus disease (COVID-19) risk perceptions among the public to enhance risk communication efforts: a practical approach for outbreaks, Finland, February 2020.

Understanding risk perceptions of the public is critical for risk communication. In February 2020, the Finnish Institute for Health and Welfare started collecting weekly qualitative data on coronavirus disease (COVID-19) risk perception that informs risk communication efforts. The process is based on thematic analysis of emails and social media messages from the public and identifies factors linked to appraisal of risk magnitude, which are developed into risk communication recommendations together with health and communication experts.

Serological and molecular findings during SARS-CoV-2 infection: the first case study in Finland, January to February 2020.

The first case of coronavirus disease (COVID-19) in Finland was confirmed on 29 January 2020. No secondary cases were detected. We describe the clinical picture and laboratory findings 3-23 days since the first symptoms.

Outbreak of invasive pneumococcal disease among shipyard workers, Turku, Finland, May to November 2019.

We report an outbreak of invasive pneumococcal disease and pneumococcal pneumonia among shipyard workers, in Turku, Southwest Finland. In total, 31 confirmed and six probable cases were identified between 3 May and 28 November 2019. serotypes 12F, 4 and 8 were isolated from blood cultures of 25 cases.

Public health response to large influx of asylum seekers: implementation and timing of infectious disease screening.

Background: Infectious disease screening of migrants at increased risk is a feature of national infection prevention and control measures. Asylum seekers in Finland are offered screening of tuberculosis (TB), hepatitis B, human immunodeficiency virus infection (HIV) and syphilis based on individual risk assessment. We aimed to evaluate the public health response to a large influx of asylum seekers to Finland in 2015-2016 with respect to national guidelines on initial health services and infectious disease screening.

Vaccine-preventable disease incidence of pneumococcal conjugate vaccine in the Finnish invasive pneumococcal disease vaccine trial.

Estimation of the full disease burden caused by Streptococcus pneumoniae is challenging due to the difficulties in assigning the aetiology especially in lower and upper respiratory infections. We estimated the pneumococcal disease burden by using the vaccine-preventable disease incidence (VPDI) of PHiD-CV10 vaccine (GSK) in our clinical trial setting. Finnish Invasive Pneumococcal disease (FinIP) trial was a cluster-randomized, double-blind trial in children <19 months who received PHiD-CV10 in 52 clusters or hepatitis B/A vaccine as control in 26 clusters according to 3+1 or 2+1 schedules (infants < 7 months) or catch-up schedules (children 7-18 months).

A cluster of measles linked to an imported case, Finland, 2017.

One imported and five secondary cases of measles were detected in Finland between June and August 2017. The measles sequences available for five laboratory-confirmed cases were identical and belonged to serotype D8. The large number of potentially exposed Finnish and foreign individuals called for close cooperation of national and international public health authorities and other stakeholders.

Establishing and maintaining the National Vaccination Register in Finland.

Computerised, population-based vaccination registers are valuable tools for assessing the vaccine uptake and impact in populations. However, reliable impact assessment is only possible if the data quality can be reviewed and monitored continuously. This report describes the establishment and maintenance of the National Vaccination Register (NVR) in Finland.

Effectiveness of the 10-Valent Pneumococcal Nontypeable Haemophilus influenzae Protein D-Conjugated Vaccine (PHiD-CV) Against Carriage and Acute Otitis Media-A Double-Blind Randomized Clinical Trial in Finland.

Unlabelled: After administering the 10-valent pneumococcal polysaccharide nontypeable Haemophilus influenzae protein D-conjugated vaccine (PHiD-CV) to children aged 2-18 months, we observed a reduction in vaccine-type nasopharyngeal carriage, resulting in a reduction of overall pneumococcal nasopharyngeal carriage, which may be important for indirect vaccine effects. We noted a trend toward reduction of acute otitis media.

Background: This trial (ClinicalTrials.

Respiratory diphtheria in an asylum seeker from Afghanistan arriving to Finland via Sweden, December 2015.

In December 2015, an asylum seeker originating from Afghanistan was diagnosed with respiratory diphtheria in Finland. He arrived in Finland from Sweden where he had already been clinically suspected and tested for diphtheria. Corynebacterium diphtheriae was confirmed in Sweden and shown to be genotypically and phenotypically toxigenic.

Effectiveness of the Ten-valent Pneumococcal Conjugate Vaccine Against Tympanostomy Tube Placements in a Cluster-randomized Trial.

Background: We evaluated the impact of the new pneumococcal Haemophilus influenzae protein D conjugate vaccine (PHiD-CV10, GSK Vaccines) on tympanostomy tube placements (TTPs).

Methods: Finnish Invasive Pneumococcal disease vaccine trial was a nationwide phase III/IV cluster-randomized, double-blind trial. Children younger than 19 months received PHiD-CV10 in two thirds of clusters (N = 52) or hepatitis B or A vaccine as control in 26 clusters according to 3 + 1 or 2 + 1 schedules (infants younger than 7 months) or catch-up schedules.

Health benefit for the child and promotion of the common good were the two most important reasons for participation in the FinIP vaccine trial.

Background And Aims: The Finnish Invasive Pneumococcal disease (FinIP) vaccine trial was a nationwide cluster-randomised double-blind trial designed to demonstrate the effectiveness of pneumococcal conjugate vaccine in vaccinated children and indirect effects in unvaccinated populations. Together with the parallel carriage/AOM trial, over 47,000 children were enrolled, 52% of the initial target. We conducted a questionnaire study to find out which factors affected parents' decision on their child's study participation.

Lipid-based nutrient supplements do not affect the risk of malaria or respiratory morbidity in 6- to 18-month-old Malawian children in a randomized controlled trial.

Background: There is evidence to support the use of lipid-based nutrient supplements (LNSs) to promote child growth and development in low-income countries, but there is also a concern regarding the safety of using iron-fortified products in malaria-endemic areas.

Objective: The objective of this study was to test the hypothesis that 6- to 18-mo-old rural Malawian children receiving iron-containing (6 mg/d) LNSs would not have excess morbidity compared with infants receiving no supplementation.

Methods: A randomized controlled trial allocated 840 children to receive daily supplementation with 54 g/d LNS with milk protein base (milk-LNS), 54 g/d LNS with soy protein base (soy-LNS), 71 g/d corn-soy blend (CSB), or no supplementation from 6 to 18 mo of age.

Distance to health services affects local-level vaccine efficacy for pneumococcal conjugate vaccine (PCV) among rural Filipino children.

Pneumococcal conjugate vaccines (PCVs) have demonstrated efficacy against childhood pneumococcal disease in several regions globally. We demonstrate how spatial epidemiological analysis of a PCV trial can assist in developing vaccination strategies that target specific geographic subpopulations at greater risk for pneumococcal pneumonia. We conducted a secondary analysis of a randomized, placebo-controlled, double-blind vaccine trial that examined the efficacy of an 11-valent PCV among children less than 2 y of age in Bohol, Philippines.

Effect of pneumococcal Haemophilus influenzae protein D conjugate vaccine (PHiD-CV10) on outpatient antimicrobial purchases: a double-blind, cluster randomised phase 3-4 trial.

Background: Antimicrobial drugs are frequently prescribed to children for respiratory tract infections such as otitis, tonsillitis, sinusitis, and pneumonia. We assessed the effect of the ten-valent pneumococcal Haemophilus influenzae protein D conjugate vaccine (PHiD-CV10; GlaxoSmithKline) on antimicrobial purchases.

Methods: In this nationwide phase 3-4 cluster-randomised, double-blind trial, children younger than 19 months were randomly assigned to receive PHiD-CV10 in 52 of 78 clusters or hepatitis B or A vaccine as control in 26 clusters according to three plus one or two plus one schedules (infants younger than 7 months) or catch-up schedules (children aged 7-18 months).

Providing lipid-based nutrient supplements does not affect developmental milestones among Malawian children.

Aim: To assess whether using lipid-based nutrient supplements (LNS) to complement the diets of infants and young children affected when they achieved selected developmental milestones.

Methods: In rural Malawi, 840 6-month-old healthy infants were enrolled to a randomised trial. Control participants received no supplements, others were provided with milk-containing LNS, soy-containing LNS or corn-soy blend (CSB) for 12 months.

Effect of complementary feeding with lipid-based nutrient supplements and corn-soy blend on the incidence of stunting and linear growth among 6- to 18-month-old infants and children in rural Malawi.

Low nutritional value of complementary foods is associated with high incidence of childhood growth stunting in low-income countries. This study was done to test a hypothesis that dietary complementation with lipid-based nutrient supplements (LNS) promotes linear growth and reduces the incidence of severe stunting among at-risk infants. A total of 840 6-month-old healthy infants in rural Malawi were enrolled to a randomised assessor-blinded trial.

Effectiveness of the ten-valent pneumococcal Haemophilus influenzae protein D conjugate vaccine (PHiD-CV10) against invasive pneumococcal disease: a cluster randomised trial.

Background: The Finnish Invasive Pneumococcal disease (FinIP) vaccine trial was designed to assess the effectiveness of a pneumococcal vaccine containing ten serotype-specific polysaccharides conjugated to Haemophilus influenzae protein D, tetanus toxoid, and diphtheria toxoid as the carrier proteins (PHiD-CV10) against invasive pneumococcal disease.

Methods: In this cluster-randomised, double-blind trial, children aged younger than 19 months received PHiD-CV10 in 52 clusters or hepatitis vaccines as control in 26 clusters. Infants aged younger than 7 months at the first vaccination received either a 3+1 or a 2+1 vaccination schedule, children aged 7-11 months received a 2+1 schedule, and those 12-18 months of age received a two-dose schedule.

A lipid-based nutrient supplement but not corn-soy blend modestly increases weight gain among 6- to 18-month-old moderately underweight children in rural Malawi.

Although widely used, there is little information concerning the efficacy of corn-soy blend (CSB) supplementation in the treatment of moderate underweight in African children. Lipid-based nutrient supplements (LNS), which have proven to be beneficial treatment for severely wasted children, could offer benefits to less severely affected individuals. We conducted a clinical randomized trial to determine whether LNS or CSB supplementation improves weight gain of moderately underweight children.

Efficacy of an 11-valent pneumococcal conjugate vaccine against radiologically confirmed pneumonia among children less than 2 years of age in the Philippines: a randomized, double-blind, placebo-controlled trial.

Background: Pneumococcus is a leading cause of childhood pneumonia worldwide. Pneumococcal conjugate vaccines (PCV) have demonstrated efficacy against childhood invasive pneumococcal disease (IPD) and pneumonia in the United States and Africa. No information is available from Asia on the impact of PCV on childhood pneumonia.

Clinical case review: a method to improve identification of true clinical and radiographic pneumonia in children meeting the World Health Organization definition for pneumonia.

Background: The World Health Organization's (WHO) case definition for childhood pneumonia, composed of simple clinical signs of cough, difficult breathing and fast breathing, is widely used in resource poor settings to guide management of acute respiratory infections. The definition is also commonly used as an entry criteria or endpoint in different intervention and disease burden studies.

Methods: A group of paediatricians conducted a retrospective review of clinical and laboratory data including C-reactive protein concentration and chest radiograph findings among Filipino children hospitalised in the Bohol Regional Hospital who were enrolled in a pneumococcal vaccine efficacy study and had an episode of respiratory disease fulfilling the WHO case definition for clinical pneumonia.

Similar antibody concentrations in Filipino infants at age 9 months, after 1 or 3 doses of an adjuvanted, 11-valent pneumococcal diphtheria/tetanus-conjugated vaccine: a randomized controlled trial.

In Filipino infants, 1 dose of an adjuvanted, 11-valent pneumococcal conjugate vaccine (serotypes 1, 4, 5, 7F, 9V, 19F, and 23F conjugated to tetanus protein; and serotypes 3, 6B, 14, and 18C conjugated to diphtheria toxoid) administered alone at age 18 weeks (11PncTD1) elicited similar antibody concentrations at age 9 months as those elicited by 3 doses (11PncTD3) administered concomitantly with national program vaccines, at ages 6, 10, and 14 weeks. Geometric mean antibody concentrations ranged from 0.36 microg/mL (for serotype 18C) to 5.

Safety and immunogenicity of three doses of an eleven-valent diphtheria toxoid and tetanus protein--conjugated pneumococcal vaccine in Filipino infants.

Background: An 11-valent pneumococcal conjugate vaccine could provide significantly larger reduction in pneumococcal disease burden than the currently available 7-valent vaccine formulation in many countries.

Methods: In total, 50 infants were enrolled to this open, uncontrolled study, which evaluated the safety and immunogenicity of an aluminium adjuvanted 11-valent mixed-carrier diphtheria toxoid or tetanus protein-conjugated vaccine (11-PncTD) when administered in three doses at 6, 10 and 14 weeks of age simultaneously with DTwP//PRP-T and OPV vaccines in Filipino infants.

Results: The rates of local reactions between the two injection sites, those associated with the 11-PncTD vaccine and those with the DTwP//PRP-T were almost of equal frequency for all three vaccine doses except for induration, which was significantly more common in the DTP//PRP-T injection site.

Functional antibodies elicited by an 11-valent diphtheria-tetanus toxoid-conjugated pneumococcal vaccine.

The aluminium-adjuvanted 11-valent pneumococcal conjugate vaccine containing polysaccharides 1, 4, 5, 7F, 9V, 19F, and 23F (coupled to tetanus protein) and polysaccharides 3, 6B, 14, and 18C (coupled to diphtheria toxoid) elicits high antibody concentrations in Filipino infants when given at ages 6, 10, and 14 weeks and 9 months simultaneously with the national vaccination program. We evaluated functional activity of these antibodies by using a viable cell opsonophagocytic assay (OPA). The OPA titers correlated (r=0.
