Introduction
In 2008, following a rubella epidemic, the Egyptian Ministry of Health implemented a Measles Rubella (MR) catch-up campaign, based on WHO recommendations for supplementary immunization activities to eliminate measles by 2010. The age group targeted was 10–20 years. This campaign was unique in Egypt as it was the first national vaccination campaign which included university students.Aim
To report uptake of MR vaccine and reasons for declining the vaccine among medical and non-medical students in the campaign and to assess the knowledge about the vaccine and the diseases.Methods
The study was conducted in two stages. In the first stage during the vaccination sessions, medical and other students (N = 310) were given a questionnaire to assess their knowledge of the campaign and the vaccine. The second stage (N = 341) was carried out when the campaign was completed to assess vaccine uptake among medical students.Results
Posters displayed inside the university were reported to be the main source of information about the campaign. Students were generally poorly informed about both vaccine adverse effects, and contraindications although medical students tended to be better informed than other students. Overall 64.8% medical students accepted the vaccine with higher uptake among females than males (85.9 and 58.3% respectively). Non-compliant students had a significantly higher mean age. Almost half of students who did not accept the vaccine gave their reason as having little information about the vaccine (43.3%).Conclusion
The MR campaign in Ain Shams University may have been more successful with better use of health education messages. 相似文献2.

Background
In October 2012, the Meningococcal A conjugate vaccine MenAfriVac was granted a label variation to allow for its use in a controlled temperature chain (CTC), at temperatures of up to 40 °C for not more than four days. This paper describes the first field use of MenAfriVac in a CTC during a campaign in Benin, December 2012, and assesses the feasibility and acceptability of the practice.Methods
We implemented CTC in one selected district, Banikoara (target population of 147,207; 1–29 years of age), across 14 health facilities and 150 villages. We monitored the CTC practice using temperature indicators and daily monitoring sheets. At the end of the campaign we conducted a face-to-face survey to assess vaccinators’ and supervisors’ experience with CTC.Findings
A mix of strategies were implemented in the field to maximize the benefits from CTC practice, depending on the distance from health centre to populations and the availability of a functioning refrigerator in the health centre. Coverage across Banikoara was 105.7%. Over the course of the campaign only nine out of approx. 15,000 vials were discarded due to surpassing the 4 day CTC limit and no vial was discarded because of exposure to a temperature higher than 40 °C or due to the Vaccine Vial Monitor (VVM) reaching its endpoint. Overall confidence and perceived usefulness of the CTC approach were very high among vaccinators and supervisors.Interpretation
Vaccinators and supervisors see clear benefits from the CTC approach in low income settings, especially in hard-to-reach areas or where cold chain is weak. Taking advantage of the flexibility offered by CTC opens the door for the implementation of new immunization strategies to ensure all those at risk are protected. 相似文献3.
Introduction
During the 2009–2010 H1N1 pandemic, children and high-risk adults had priority for vaccination. Vaccine in short supply was allocated to states pro-rata by population, but vaccination rates as of January 2010 varied among states from 21.3% to 84.7% for children and 10.4% to 47.2% for high-risk adults. States had different campaign processes and decisions.Objective
To determine program and system factors associated with higher state pandemic vaccination coverage for children and high-risk adults during an emergency response with short supply of vaccine.Methods
Regression analysis of factors predicting state-specific H1N1 vaccination coverage in children and high-risk adults, including state campaign information, demographics, preventive or health-seeking behavior, preparedness funding, providers, state characteristics, and surveillance data.Results
Our modeling explained variation in state-specific vaccination coverage with an adjusted R-squared of 0.82 for children and 0.78 for high-risk adults. We found that coverage of children was positively associated with programs focusing on school clinics and with a larger proportion of doses administered in public sites; negatively with the proportion of children in the population, and the proportion not visiting a doctor because of cost. The coverage for high-risk adults was positively associated with shipments of vaccine to “general access” locations, including pharmacy and retail, with the percentage of women with a Pap smear within the past 3 years and with past seasonal influenza vaccination. It was negatively associated with the expansion of vaccination to the general public by December 4, 2009. For children and high-risk adults, coverage was positively associated with the maximum number of ship-to-sites and negatively associated with the proportion of medically underserved population.Conclusion
Findings suggest that distribution and system decisions such as vaccination venues and providers targeted can positively impact vaccination rates for children and high-risk adults. Additionally, existing health infrastructure, health-seeking behaviors, and access affected coverage. 相似文献4.
Introduction
During the 2009–2010 H1N1 pandemic, vaccine in short supply was allocated to states pro rata by population, yet the vaccination rates of adults differed by state. States also differed in their campaign processes and decisions. Analyzing the campaign provides an opportunity to identify specific approaches that may result in higher vaccine uptake in a future event of this nature.Objective
To determine supply chain and system factors associated with higher state H1N1 vaccination coverage for adults in a system where vaccine was in short supply.Methods
Regression analysis of factors predicting state-specific H1N1 vaccination coverage in adults. Independent variables included state campaign information, demographics, preventive or health-seeking behavior, preparedness funding, providers, state characteristics, and H1N1-specific state data.Results
The best model explained the variation in state-specific adult vaccination coverage with an adjusted R-squared of 0.76. We found that higher H1N1 coverage of adults is associated with program aspects including shorter lead-times (i.e., the number of days between when doses were allocated to a state and were shipped, including the time for states to order the doses) and less vaccine directed to specialist locations. Higher vaccination coverage is also positively associated with the maximum number of ship-to locations, past seasonal influenza vaccination coverage, the percentage of women with a Pap smear, the percentage of the population that is Hispanic, and negatively associated with a long duration of the epidemic peak.Conclusion
Long lead-times may be a function of system structure or of efficiency and may suggest monitoring or redesign of distribution processes. Sending vaccine to sites with broad access could be useful when covering a general population. Existing infrastructure may be reflected in the maximum number of ship-to locations, so strengthening routine influenza vaccination programs may help during emergency vaccinations also. Future research could continue to inform program decisions. 相似文献5.

Background
The risk factors of underutilization of childhood vaccines in populations with high access to health services are not fully understood.Objectives
To determine vaccination coverage and factors associated with underutilization of childhood vaccines in a population with sub-optimal vaccination compliance, despite a high health care access.Methods
The study was conducted among 430 children from ultraorthodox Jewish communities in the Bnei Brak city and Jerusalem district. Data on immunization status, socio-demographic factors and on parents’ attitudes regarding vaccines were obtained from medical records and through parents’ interviews.Results
The proportion of fully vaccinated children was 65% in 2- to 5-year-old ultraorthodox children from Jerusalem district, and 86% in 2.5-year-old children from Bnei Brak city. The factors that were significantly associated with vaccines underutilization in Bnei Brak were having >6 siblings, maternal academic education, parental religious beliefs against vaccination, perceived risk of vaccine preventable diseases as low, and mistrust in the Ministry of Health (MOH). Similarly, in Jerusalem, religious beliefs against vaccination, and the perceived low risk of vaccine preventable diseases significantly increased the likelihood of under-immunization, while having a complementary health insurance was inversely related with vaccines underutilization.Conclusions
The risk factors of under-immunization are in part modifiable, by means of health education on the risks of vaccine preventable diseases and by improving the trust in the MOH. The leaders of the ultraorthodox communities could play an important role in such interventions. 相似文献6.
Background
In September 2007, a school-based human papillomavirus (HPV) vaccination program targeting grade 8 girls (approximately 13 years old) and delivered by public health was implemented in Ontario, Canada. We assessed reports of adverse events following immunization (AEFI) from the school-based program as part of quadrivalent HPV (HPV4) vaccine safety surveillance and to contribute to a comprehensive HPV vaccine program evaluation.Methods
AEFIs following HPV4 vaccine (Gardasil®) administered between September 1, 2007 and December 31, 2011 were extracted from the province's reportable disease system. Confirmed AEFI reports among females 12–15 years old (i.e. assumed to have received vaccine through the program) were included. Events were grouped according to provincial AEFI case definitions. Rates were calculated using doses distributed as the denominator.Results
Between 2007 and 2011, 133 confirmed AEFIs were reported while 691,994 HPV4 vaccine doses were distributed in the school-based program. The overall reporting rate was 19.2 HPV4 AEFI per 100,000 doses distributed. Annual reporting rates decreased from 30.0 to 18.3 per 100,000 doses distributed. Frequently reported events included ‘allergic reaction—dermatologic/mucosa’ (25%), ‘rash’ (22%), and ‘local/injection site reaction’ (20%); 26% of reports had a non-specific event of ‘other severe/unusual events’ selected. Ten serious AEFIs were reported (7.5% of reports) including 2 anaphylaxis, 2 seizures, 1 thrombocytopenia and 1 death. Further review found that the reports of anaphylaxis did not meet the Brighton anaphylaxis definition and the death was attributed to a preexisting cardiac condition.Conclusions
Overall these findings are consistent with the safety profile of HPV4 vaccine from pre-licensure clinical trials and post-marketing surveillance reports and importantly, no new safety signals were identified, especially no reports of VTE in this younger female population. Continued assessment of HPV4 AEFI surveillance data may be important to detect and investigate safety signals. 相似文献7.
Introduction
Home health aides (HAs) receive limited training and reach many older patient populations highly susceptible to influenza virus. We sought to examine socio-demographic correlates of seasonal flu vaccination receipt among HAs.Methods
We analyzed data from the 2007 U.S. National Home Health Aide Survey, a nationally representative sample of HAs reporting on occupational status, job and demographic characteristics and receipt of seasonal flu vaccine (n = 3377).Results
Seasonal flu vaccine receipt was low among all types of HAs (43.9%). After adjustment for socio-demographic indicators (i.e. age, gender, race and health insurance), home health, home care, hospice and personal care attendants were significantly less likely to report receiving seasonal flu vaccine as compared to licensed nursing assistants (adjusted odds ratio, AOR = 0.42, 95% CI [0.20–0.85]; 0.41, [0.17–0.99]; 0.50, [0.26–0.97], and 0.53, [0.26–0.99], respectively).Conclusion
Targeted effective vaccination campaigns are needed to improve vaccination rates among home health aides. 相似文献8.
Introduction
Cervical screening has helped decrease the incidence of cervical cancer, but the disease remains a burden for women. Human Papillomavirus (HPV) vaccination is now a promising tool for control of cervical cancer. Nordic countries (Denmark, Finland, Greenland, Iceland, Norway and Sweden) are relatively wealthy with predominantly publicly paid health care systems. The aim of this paper was to provide an update of the current status of introduction of HPV vaccine into the childhood vaccination programs in this region.Methods
Data on cervical cancer, cervical screening programs, childhood immunization and HPV vaccination programs for Nordic countries were searched via PubMed and various organizations. We furthermore contacted selected experts for information.Results
The incidence of cervical cancer is highest in Greenland (25 per 100,000, age standardized, World Standard Population, ASW) and lowest in Finland (4 per 100,000 ASW) and rates in the other Nordic countries vary between 7 and 11 per 100,000 ASW. Greenland and Denmark were first to introduce HPV vaccination, followed by Norway. Vaccination programs are underway in Sweden and Iceland, while Finland has just recently recommended introduction of vaccination. HPV vaccination has been intensively debated, in particular in Denmark and Norway.Discussion
In Nordic countries with a moderate risk of cervical cancer and a publicly paid health care system, the introduction of HPV vaccination was a priority issue. Many players became active, from the general public to health professionals, special interest groups, and the vaccine manufacturers. These seemed to prioritize different health care needs and weighed differently the uncertainty about the long-term effects of the vaccine.Conclusion
HPV vaccination posed a pressure on public health authorities to consider the evidence for and against it, and on politicians to weigh the wish for cervical cancer protection against other pertinent health issues. 相似文献9.
Background
The aim of this study was to assess factors influencing 2009 H1N1 influenza vaccination among a demographically diverse group of day care-aged children. Day care children were chosen because they were an initial target group for vaccination and are at higher risk of influenza infection than children cared for at home.Methods
A cross-sectional study was conducted from March to May 2010 among parents of day care aged children in 13 day care facilities in Miami-Dade County. Data was collected by an anonymous self-administered two-page 20 question survey which consisted of demographic variables and information regarding 2009 H1N1 influenza vaccine knowledge, attitude and acceptance. Data was analyzed using SAS to conduct both bivariate and multivariate analyses.Results
There were 773 participants in the study. The response rate ranged from 42% to 72.2% among day care centers. A total of 172 parents (22.3%) and 225 (29.1%) children had received the 2009 H1N1 influenza vaccine. Non-Hispanic White and Black parents were more likely to vaccinate their children than Hispanic and Haitian parents. Primary reasons for non-vaccination included vaccine safety (36.7%) and side effects (27.1%). Among parents who spoke with a health care professional, 274 (61.4%) stated the health care professional recommended the vaccine.Conclusion
Misperceptions about influenza vaccination among parents created a barrier to 2009 H1N1 influenza vaccination. Parents who got the vaccine, who believed the vaccine was safe and whose children had a chronic condition were more likely to immunize their children. Clear, reliable and consistent vaccine information to the public and health care providers and initiatives targeting minority groups may increase vaccination coverage among this population. 相似文献10.

Objective
Human papillomavirus (HPV) vaccine uptake in many countries has been sub-optimal. We examine several issues associated with non-vaccination that have received particular attention, including fears about sexual risk compensation, concerns about vaccine safety, inadequate vaccination recommendations by health care providers (HCPs), and distrust due to the perceived “newness” of HPV vaccines.Methods
Selective review of behavioral and social science literature on HPV vaccine attitudes and uptake.Results
There is no evidence of post-vaccination sexual risk compensation, HPV vaccines are quite safe, and they can no longer be considered “new”. Nonetheless, research findings point to these issues and, most importantly, to the failure of HCPs to adequately recommend HPV vaccine as major drivers of non-vaccination.Conclusion
Most fears related to HPV vaccine are more related to myth than reality. In the absence of major health policy initiatives, such as those implemented in Canada, the U.K., and Australia, a multi-level, multi-faceted approach will be required to achieve high rates of HPV vaccination. It will be essential to focus on the education of HCPs regarding indications for HPV vaccination and approaches to communicating most effectively with parents and patients about the safety and benefits of vaccination and the risks associated with non-vaccination. 相似文献11.
Active surveillance for influenza vaccine adverse events: the integrated vaccine surveillance system
Objectives
We conducted a pilot study of the Integrated Vaccine Surveillance System (IVSS), a novel active surveillance system for monitoring influenza vaccine adverse events that could be used in mass vaccination settings.Methods
We recruited 605 adult vaccinees from a convenience sample of 12 influenza vaccine clinics conducted by public health departments of two U.S. metropolitan regions. Vaccinees provided daily reports on adverse reactions following immunization (AEFI) using an interactive voice response system (IVR) or the internet for 14 consecutive days following immunization. Followup with nonrespondents was conducted through computer-assisted telephone interviewing (CATI). Data on vaccinee reports were available real-time through a dedicated secure website.Results
90% (545) of vaccinees made at least one daily report and 49% (299) reported consecutively for the full 14-day period. 58% (315) used internet, 20% (110) IVR, 6% (31) CATI, and 16% (89) used a combination for daily reports. Of the 545 reporters, 339 (62%) reported one or more AEFI, for a total of 594 AEFIs reported. The majority (505 or 85%) of these AEFIs were mild symptoms.Conclusions
It is feasible to develop a system to obtain real-time data on vaccine adverse events. Vaccinees are willing to provide daily reports for a considerable time post vaccination. Offering multiple modes of reporting encourages high response rates. Study findings on AEFIs showed that the IVSS was able to exhibit the emerging safety profile of the 2008 seasonal influenza vaccine. 相似文献12.

Introduction
Two rotavirus vaccines have been licensed globally since 2006. In China, only a lamb rotavirus vaccine is licensed and several new rotavirus vaccines are in development. Data regarding the projected health impact and cost-effectiveness of vaccination of children in China against rotavirus will assist policy makers in developing recommendations for vaccination.Methods
Using a Microsoft Excel model, we compared the national health and economic burden of rotavirus disease in China with and without a vaccination program. Model inputs included 2007 data on burden and cost of rotavirus outcomes (deaths, hospitalizations, outpatient visits), projected vaccine efficacy, coverage, and cost. Cost-effectiveness was measured in US dollars per disability-adjusted life-year (DALY) and US dollars per life saved.Results
A 2-dose rotavirus vaccination program could annually avert 3013 (62%) deaths, 194,794 (59%) hospitalizations and 1,333,356 (51%) outpatient visits associated with rotavirus disease in China. The medical break-even price of the vaccine is $1.19 per dose. From a societal perspective, a vaccination program would be highly cost-effective in China at the vaccine price of $2.50 to $5 per dose, and be cost-effective at the price of $10 to $20 per dose.Conclusions
A national rotavirus vaccination program could be a cost-effective measure to effectively reduce deaths, hospitalizations, and outpatient visits due to rotavirus disease in China. 相似文献13.
Introduction
The yellow-fever vaccination center of the Tourcoing Hospital (France) has been accessible to Belgian travelers since its opening in 1994.Method
The authors reported the specificities of these consultations during the year 2010, by retrospectively analyzing electronic medical records.Results
Some medical issues encountered during the consultation were due to differences in vaccination schedules: for the polio vaccine, since the last dose is administered between 5 and 7 years of age in Belgium; and for the measles vaccine since a late two-dose schedule (second dose between 12 and 13 years of age) is recommended in this country. Moreover, some specific vaccines are available only in Belgium: a diphtheria-tetanus bivalent vaccine, and a live attenuated oral typhoid vaccine.Discussion
The specificities of the Belgian border traveler consultation in our French yellow-fever center are due to a difference in European vaccination schedules; the physician must be aware of these.Conclusion
The physician has to propose updates on vaccination schedules, and be aware of yellow-fever vaccine compatibility with vaccines recently administered in Belgium. 相似文献14.
Background
Influenza vaccine uptake rates are low compared with uptake rates of many other vaccines. It is unclear how this differs between risk groups in the population and between pandemic and non-pandemic influenza vaccines.Aim
This study sought to estimate uptake rates of pandemic and seasonal influenza vaccines among clinical risk groups in the UK during the 2009/2010 influenza season and to identify predictors of vaccine uptake in this cohort.Methods
Uptake rates were calculated using data from the UK General Practice Research Database (GPRD). Predictors of vaccination were identified using a modified Poisson regression with robust standard error estimates.Results
Uptake of pandemic influenza vaccine in clinical risk groups was 40.3% and uptake of seasonal influenza vaccine was 61.3%. Factors found to be predictive of seasonal and pandemic influenza vaccination included age and the total number of underlying health conditions an individual had. At risk individuals in those age groups in which universal vaccination of the general population was recommended were more likely to have been vaccinated than individuals in age groups in which only clinical risk groups were recommended for vaccination; hence children in clinical risk groups were more likely to receive pandemic than seasonal influenza vaccine. In older people, having a history of Guillain Barré syndrome was associated with a reduced likelihood of receipt of both seasonal (IRRadj 0.83, CI95 0.77–0.90) and pandemic influenza vaccines (IRRadj 0.82, CI95 0.73–0.92).Discussion
Uptake of pandemic influenza vaccine was lower than that of seasonal influenza vaccine among those at a clinically high risk of influenza related morbidity. This suggests that vaccination strategies may need to be altered during future pandemics. Recommending universal vaccination within age categories in which there is a large proportion of high risk individuals could be considered as this may result in higher uptake among clinical risk groups. 相似文献15.
Objective
The purpose of the study was to quantitatively evaluate the effect of the hepatitis B vaccine based on 33 years of data published on the HBsAg- and anti-HBs-positive rates.Methods
All data were obtained from studies in published Chinese scientific journals from 1977 to 2009. The HBsAg- or anti-HBs-positive rate over a certain observation period was presented.Results
When the anti-HBs-positive rate was low, the ability of anti-HBs to control the HBsAg-positive rate is not apparent. When the anti-HBs level is high, the ability of anti-HBs to control the HBsAg-positive rate increases gradually, and a linear relationship was observed between the HBsAg-positive rate and the anti-HBs-positive rate. However, the rate of decrease of HBsAg positivity was markedly higher than the theoretical rate.Conclusion
The effect of other known or unknown factors, in addition to the vaccination campaign, could have contributed to the decrease in the prevalence of HBV infection. 相似文献16.
Objectives
Influenza vaccination is recommended to all health care professionals (HCPs). However, vaccination rate among HCPs is low and may be due to uncertainty about the effectiveness of the vaccine and fear of its adverse effects. Therefore, this study aimed to investigate the awareness, knowledge, and attitude of HCPs towards influenza vaccination and we ascertain reasons for not getting vaccinated.Method
A cross-sectional conducted in 6 major hospitals in Saudi Arabia. 245 anonymous questionnaires were distributed to a convenient sample of staff during the 2012–2013 influenza season. The validated questionnaire consists of five sections that collect information about: demographics, attitude towards influenza vaccination, knowledge about influenza virus and vaccination, current practice and awareness of published guidelines.Results
242 completed questionnaires were received, a response rate of 98%. 38% of HCPs reported getting vaccinated. The most common reasons given by HCPs for not getting vaccinated were: fear of contracting illness (16%), belief that they are not at risk from influenza because they are young and healthy (13%) and being unaware of vaccine availability (13%). Non-availability of vaccine (43%) was the highest barrier for not providing vaccine for patients and HCPs followed by safety concerns for the patients (35%) and the respondents (33%). Almost 75% of HCPs were not aware of the influenza immunization guidelines published by the Advisory Committee on Immunization Practices and Centre for Disease Control.Conclusion
Despite the recommendations, only low percentage of HCPs in Saudi Arabian hospitals is vaccinated against influenza. The attention of health policy makers is needed to improve compliance of HCPs with guidelines on influenza vaccination. 相似文献17.

Objective
We aimed to explore the impacts of new vaccine introductions on immunization programmes and health systems in low- and middle-income countries.Methods
We conducted case studies of seven vaccine introductions in six countries (Cameroon, PCV; Ethiopia, PCV; Guatemala, rotavirus; Kenya, PCV; Mali, Meningitis A; Mali, PCV; Rwanda, HPV). Interviews were conducted with 261 national, regional and district key informants and questionnaires were completed with staff from 196 health facilities. Routine data from districts and health facilities were gathered on vaccination and antenatal service use. Data collection and analysis were structured around the World Health Organisation health system building blocks.Findings
The new vaccines were viewed positively and seemed to integrate well into existing health systems. The introductions were found to have had no impact on many elements within the building blocks framework. Despite many key informants and facility respondents perceiving that the new vaccine introductions had increased coverage of other vaccines, the routine data showed no change. Positive effects perceived included enhanced credibility of the immunisation programme and strengthened health workers’ skills through training. Negative effects reported included an increase in workload and stock outs of the new vaccine, which created a perception in the community that all vaccines were out of stock in a facility. Most effects were found within the vaccination programmes; very few were reported on the broader health systems. Effects were primarily reported to be temporary, around the time of introduction only.Conclusion
Although the new vaccine introductions were viewed as intrinsically positive, on the whole there was no evidence that they had any major impact, positive or negative, on the broader health systems. 相似文献18.
Background
In this study, we modeled the cost benefit analysis for three different measles vaccination strategies based upon three different measles-containing vaccines in Korea, 2001. We employed an economic analysis model using vaccination coverage data and population-based measles surveillance data, along with available estimates of the costs for the different strategies. In addition, we have included analysis on benefit of reduction of complication by mumps and rubella.Methods
We evaluated four different strategies: strategy 1, keep-up program with a second dose measles-mumps-rubella (MMR) vaccine at 4–6 years without catch-up campaign; strategy 2, additional catch-up campaign with measles (M) vaccine; strategy 3, catch-up campaign with measles-rubella (MR) vaccine; and strategy 4, catch-up campaign with MMR vaccine. The cost of vaccination included cost for vaccines, vaccination practices and other administrative expenses. The direct benefit of estimated using data from National Health Insurance Company, a government-operated system that reimburses all medical costs spent on designated illness in Korea.Results
With the routine one-dose MMR vaccination program, we estimated a baseline of 178,560 measles cases over the 20 years; when the catch-up campaign with M, MR or MMR vaccines was conducted, we estimated the measles cases would decrease to 5936 cases. Among all strategies, the two-dose MMR keep-up program with MR catch-up campaign showed the highest benefit-cost ratio of 1.27 with a net benefit of 51.6 billion KRW.Conclusion
Across different vaccination strategies, our finding suggest that MR catch-up campaign in conjunction with two-dose MMR keep-up program was the most appropriate option in terms of economic costs and public health effects associated with measles elimination strategy in Korea. 相似文献19.
Background
Since 2006 Human papillomavirus (HPV) vaccination has become available to adolescent girls and women in an increasing number of countries, to protect against the virus causing cervical cancer. The vaccine series is offered in three doses over 6 months, and this study aimed to identify factors associated with initiation and/or completion of the 3 dose series in (pre-) adolescent girls. Previous studies have considered intention to vaccinate rather than actual vaccination uptake.Methods
A systematic search of Medline, Medline in process, Embase and CINAHL, from 2006 to March 2011 for articles related to HPV-vaccine uptake among adolescent girls and factors potentially associated with uptake yielded 25 studies.Results
The majority of studies were surveys or retrospective reviews of data, only 5 studies reported data on program completion. Most were conducted in the United States (20/25). Higher vaccine uptake was associated with having health insurance, of older age, receipt of childhood vaccines, a higher vaccine related knowledge, more healthcare utilization, having a healthcare provider as a source of information and positive vaccine attitudes. In US settings, African American girls were less likely to have either initiated or completed the three dose vaccination series.Conclusions
HPV vaccination programs should focus on narrowing disparities in vaccine receipt in ethnic and racial groups and on providing correct information by a reliable source, e.g. healthcare providers. School-based vaccination programs have a high vaccine uptake. More studies are required to determine actual vaccine course completion and factors related to high uptake and completion, and information from a broader range of developed and developing settings is needed. 相似文献20.
