Rates of influenza vaccination in older adults and factors associated with vaccine use: A secondary analysis of the Canadian Study of Health and Aging

Background  

Influenza vaccination has been shown to reduce morbidity and mortality in the older adult population. In Canada, vaccination rates remain suboptimal. We identified factors predictive of influenza vaccination, in order to determine which segments of the older adult population might be targeted to increase coverage in influenza vaccination programs.     

A comparison of populations vaccinated in a public service and in a private hospital setting in the same area

Background  

Improving immunisation rates in risk groups is one of the main objectives in vaccination strategies. However, achieving high vaccination rates in children with chronic conditions is difficult. Different types of vaccine providers may differently attract high risk children.     

Influenza vaccination among healthcare workers in a multidisciplinary University hospital in Italy

Background  

Annual influenza vaccination is recommended for healthcare workers (HCWs) in order to reduce the morbidity associated with influenza in healthcare settings. The aim of this study was to evaluate the current vaccination status of the HCWs in one of Italy's largest multidisciplinary University Hospitals.     

Assessment of measles immunity among infants in Maputo City,Mozambique

Background  

The optimum age for measles vaccination varies from country to country and thus a standardized vaccination schedule is controversial. While the increase in measles vaccination coverage has produced significant changes in the epidemiology of infection, vaccination schedules have not been adjusted. Instead, measures to cut wild-type virus transmission through mass vaccination campaigns have been instituted. This study estimates the presence of measles antibodies among six- and nine-month-old children and assesses the current vaccination seroconversion by using a non invasive method in Maputo City, Mozambique.     

Factors associated with influenza vaccination status of residents of a rural community in Japan

Background  

The rate of influenza vaccination in Japan has declined over the past several decades. It is essential to identify community-specific factors that affect attitudes toward vaccination, but such parameters have not yet been fully determined in Japan. The present study used the Health Belief Model (HBM) to identify perceptions of influenza vaccination in a rural Japanese community.     

Influenza vaccination coverage against seasonal and pandemic influenza and their determinants in France: a cross-sectional survey

Background  

Following the emergence of the influenza A(H1N1)2009 virus, the French ministry of health decided to offer free vaccination against pandemic influenza to the entire French population. Groups of people were defined and prioritised for vaccination.     

Vaccination coverage of healthcare professionals in an infectious diseases department

Objectives

The study's objective was to evaluate with a standardized questionnaire the knowledge of healthcare workers (HCWs) regarding occupational vaccinations and their vaccination coverage.

Population and Methods

This cross-sectional survey was conducted in the department of infectious diseases of a 1796 bed-teaching hospital in Dijon, France.

Results

Fifty-seven (93%) out of 61 HCPs completed the questionnaire. Vaccination against HVB was the most frequently mentioned vaccination (79%), followed by BCG (66%), and combine vaccine against diphteria, tetanus, and polio (DTP) (66 %). Influenza was the most often quoted among recommended vaccinations (70%), followed by measles (61%), pertussis (39%), and varicella (14%). The number of correct answers was significantly correlated with age of participants, being a physician, and having had courses on vaccination. Almost all HCPs were up to date for mandatory vaccinations. In 2009 to 2010, vaccination rates against seasonal flu and H1N1 flu reached 88%. Only 52% of HCPs knew about their pertussis immunization and only a third of those born before 1980 had been tested for measles.

Conclusions

HCPs knowledge of mandatory vaccinations is adequate but more limited for recommended vaccinations. Information on influenza vaccination has significantly improved its perception among HCPs resulting in a better adhesion to vaccination.     

Parents' perceived vulnerability and perceived control in preventing Meningococcal C infection: a large-scale interview study about vaccination

Background  

Parents' reported ambivalence toward large-scale vaccination programs for childhood diseases may be related to their perception of the risks of side-effects or safety of vaccination and the risk of contracting the disease. The aim of this study is to evaluate parents' perceptions of their child's risk contracting a Meningococcal C infection and parents' perceived control in preventing infection in relation to their evaluation of the safety, effectiveness and usefulness of vaccination.     

Fathers' intentions to accept human papillomavirus vaccination for sons and daughters: exploratory findings from rural Honduras

Objectives  

Little is known about fathers’ attitudes toward human papillomavirus (HPV) vaccination in low-resource settings. We sought to determine the awareness of HPV vaccination among Honduran fathers, and to assess their intention to accept HPV vaccination for their sons and daughters.     

Parental knowledge of paediatric vaccination

Background  

Although routine vaccination is a major tool in the primary prevention of some infectious diseases, there is some reluctance in a proportion of the population. Negative parental perceptions of vaccination are an important barrier to paediatric vaccination. The aim of this study was to investigate parental knowledge of paediatric vaccines and vaccination in Catalonia.     

Burden of paediatric Rotavirus Gastroenteritis (RVGE) and potential benefits of a universal Rotavirus vaccination programme with a pentavalent vaccine in Spain

Background  

Rotavirus is the most common cause of gastroenteritis in young children worldwide. The aim of the study was to assess the health outcomes and the economic impact of a universal rotavirus vaccination programme with RotaTeq, the pentavalent rotavirus vaccine, versus no vaccination programme in Spain.     

Risk factors for hepatitis B virus infection in Rio de Janeiro,Brazil

Background  

Despite international efforts to prevent hepatitis B virus (HBV) infection through global vaccination programs, new cases are still being reported throughout the world.     

Variations in influenza vaccination coverage among the high-risk population in Sweden in 2003/4 and 2004/5: a population survey

Background  

In Sweden, the vaccination campaign is the individual responsibility of the counties, which results in different arrangements. The aim of this study was to find out whether influenza vaccination coverage rates (VCRs) had increased between 2003/4 and 2004/5 among population at high risk and to find out the influence of personal preferences, demographic characteristics and health care system characteristics on VCRs.     

Logistics of community smallpox control through contact tracing and ring vaccination: a stochastic network model

Background  

Previous smallpox ring vaccination models based on contact tracing over a network suggest that ring vaccination would be effective, but have not explicitly included response logistics and limited numbers of vaccinators.     

Childhood vaccination in informal urban settlements in Nairobi,Kenya: Who gets vaccinated?

Background  

Recent trends in global vaccination coverage have shown increases with most countries reaching 90% DTP3 coverage in 2008, although pockets of undervaccination continue to persist in parts of sub-Saharan Africa particularly in the urban slums. The objectives of this study were to determine the vaccination status of children aged between 12-23 months living in two slums of Nairobi and to identify the risk factors associated with incomplete vaccination.     

Determinants of vaccination coverage in rural Nigeria

Background  

Childhood immunization is a cost effective public health strategy. Expanded Programme on Immunisation (EPI) services have been provided in a rural Nigerian community (Sabongidda-Ora, Edo State) at no cost to the community since 1998 through a privately financed vaccination project (private public partnership). The objective of this survey was to assess vaccination coverage and its determinants in this rural community in Nigeria     

Défaut de couverture vaccinale pneumococcique chez l’adulte à risque

Objective

This study had for aim to assess pneumococcal vaccination rates in hospitalized patients.

Design

A prospective study was carried out in two medical wards of the Nice University Hospital, France. Patients were included from December 31, 2007 to February 12, 2008.

Results

Hundred and thirty-seven patients, aged 62 ± 20 years, were included. Pneumococcal vaccination was indicated for 62 patients (45 %). Among these 62 patients, 53 (85 %) had not been vaccinated in the previous 5 years, for the following reasons: no medical advice on vaccination (36 cases), no medical consultation in the past years (nine cases), patient opposed to vaccination (two cases), physician opposed to vaccination (one case), miscellaneous (five cases). Among the 53 patients, seven were vaccinated during their hospital stay and 13 were advised to be vaccinated by their general practitioner.

Conclusions

This study highlights a low rate of pneumococcal vaccination in hospitalized patients, mainly due to insufficient counseling from physicians, both in community or in hospital practice.     

Evaluating human papillomavirus vaccination programs in Canada: should provincial healthcare pay for voluntary adult vaccination?

Background  

Recently, provincial health programs in Canada and elsewhere have begun rolling out vaccination against human papillomavirus for girls aged 9–13. While vaccination is voluntary, the cost of vaccination is waived, to encourage parents to have their daughters vaccinated. Adult women who are eligible for the vaccine may still receive it, but at a cost of approximately CAN$400. Given the high efficacy and immunogenicity of the vaccine, the possibility of eradicating targeted types of the virus may be feasible, assuming the vaccination programs are undertaken strategically.     

Development and psychometric validation of a self-administered questionnaire assessing the acceptance of influenza vaccination: the Vaccinees' Perception of Injection (VAPI?) questionnaire

Background  

Influenza is among the most common infectious diseases. The main protection against influenza is vaccination. A self-administered questionnaire was developed and validated for use in clinical trials to assess subjects' perception and acceptance of influenza vaccination and its subsequent injection site reactions (ISR).
