Immunization of healthcare workers (HCWs) is a major issue for infection control in healthcare facilities. The aim of this study was to evaluate knowledge regarding occupational vaccinations, HBV, varicella and influenza vaccination rates and attitudes towards influenza vaccine among HCWs.Design and setting
A cross-sectional survey was conducted in two wards (Medicine and Paediatrics) of a 1182-bed teaching hospital in Paris, France.Methods
A standardized, anonymous, self-administered questionnaire was used.Results
Of 580 HCWs, 395 (68%) completed the questionnaire. Knowledge about the occupational vaccinations of HCWs was low. HBV (69%), tuberculosis (54%) and influenza (52%) were the most cited vaccinations. Paediatric staff was more aware of influenza and pertussis immunizations (p < .05). HBV vaccination rate was 93%, among whom 65% were aware of their immune status. Influenza vaccination rate for 2006–2007 was 30% overall, ranging from 50% among physicians to 20% among paramedical staff (p < .05). Physicians based their refusal on doubts about vaccine efficacy, although paramedics feared side effects. Influenza vaccination was associated with knowledge of vaccine recommendations [OR = 1.75, 95% CI: 1.13–2.57] and contact with patients [OR = 3.05, 95% CI: 1.50–5.91].Conclusions
Knowledge of recommended occupational vaccinations is insufficient in HCWs, except for HBV and influenza. Although the HBV vaccine coverage of HCWs is satisfactory, a large proportion of them is unaware of immune status. Influenza vaccine coverage remains low, especially among paramedical staff because of fear of side effects. As vaccine coverage is associated with knowledge, educational campaigns should be strengthened to increase the adhesion of HCWs to vaccinations. 相似文献2.

Background
Vaccination of healthcare students is important to protect them from acquiring and transmitting vaccine-preventable diseases (VPDs) to high-risk patients and other healthcare workers (HCWs). The aim of the current study was to estimate the vaccination coverage, the susceptibility against VPDs, the knowledge and attitudes toward vaccinations of healthcare students studying at the Athens Technological Educational Institute.Methods
The study was conducted during the academic year 2012–2013 using a standardized questionnaire.Results
The mean knowledge score (correct answers) of healthcare students about the vaccines that are recommended by the Greek Ministry of Health for HCWs was 41%. Completed vaccination rates range from 19.6% for varicella to 80.2% for tetanus-diphtheria. A history of measles, mumps, rubella, varicella, hepatitis A, hepatitis B, or pertussis was reported by 8.2%, 4%, 5.4%, 70.4%, 1.5%, 0%, and 3% of students, respectively. Susceptibility rates were 20.5% against measles, 26.4% against mumps, 13.9% against rubella, 15.7% against varicella, 47.8% against hepatitis A, 17.3% against hepatitis B, and 19.8% against tetanus–diphtheria. Mandatory vaccination of HCWs was supported by 145 (96.7%) students.Conclusions
There are significant immunity gaps against all VPDs among healthcare students in Athens. A system to easily identify non-immune students should be established in association with efficient reminder systems. Education of healthcare students about VPDs and vaccines will improve their attitudes toward vaccinations and their vaccination coverage. Mandatory vaccinations should be considered for HCWs in order to promote safety within healthcare facilities. 相似文献3.

Objective
To evaluate Rhode Island's revised vaccination regulations requiring healthcare workers (HCWs) to receive annual influenza vaccination or wear a mask during patient care when influenza is widespread.Design
Semi-structured telephone interviews conducted in a random sample of healthcare facilities.Setting
Rhode Island healthcare facilities covered by the HCW regulations, including hospitals, nursing homes, community health centers, nursing service agencies, and home nursing care providers.Participants Staff responsible for collecting and/or reporting facility-level HCW influenza vaccination data to comply with Rhode Island HCW regulations.Methods
Interviews were transcribed and individually coded by interviewers to identify themes; consensus on coding differences was reached through discussion. Common themes and illustrative quotes are presented.Results
Many facilities perceived the revised regulations as extending their existing influenza vaccination policies and practices. Despite variations in implementation, nearly all facilities implemented policies that complied with the minimum requirements of the regulations. The primary barrier to implementing the HCW regulations was enforcement of masking among unvaccinated HCWs, which required timely tracking of vaccination status and additional time and effort by supervisors. Factors facilitating implementation included early and regular communication from the state health department and facilities’ ability to adapt existing influenza vaccination programs to incorporate provisions of the revised regulations.Conclusions
Overall, facilities successfully implemented the revised HCW regulations during the 2012–2013 influenza season. Continued maintenance of the regulations is likely to reduce transmission of influenza and resulting morbidity and mortality in Rhode Island's healthcare facilities. 相似文献4.
Introduction
Vaccination of health care workers (HCW) reduces transmission of influenza among patients, yet uptake of vaccination remains low. If vaccination education is integrated into the early medical school curriculum, will student attitudes toward the vaccine change? The objectives of the study were to: (1) Determine influenza vaccination rates among entering medical students; (2) Assess the attitudes toward influenza vaccination; (3) Evaluate the effects of a multifaceted educational intervention on attitudes to vaccination.Methods
Entering medical students were surveyed before and after an intervention at the beginning of the influenza season. This intervention provided by an inter-professional team, included education about influenza, importance of vaccination for HCWs, followed by vaccination administration practice, and ended with students vaccinating consenting classmates.Results
The pre-intervention surveys and intervention were completed by 124 of 125 (99%) students. Pre-intervention survey revealed 60 (48%) of students had been previously vaccinated. Of the vaccinated students 91% had been recommended vaccination by their healthcare provider compared to 43% of non-vaccinated students. More positive attitudes were noted in the vaccinated students compared to non-vaccinated students: importance of vaccination (p < 0.01); HCWs should be vaccinated (p < 0.01); recommendation of vaccine to family and friends (p < 0.01). 97 (78%) students completed post-intervention surveys. Significant improvement in these attitudes was noted post-intervention compared to pre-intervention: importance of vaccination 93% versus 71% (p < 0.01); HCWs should be vaccinated 95% versus 83% (p < 0.01); recommendation to family and friends 93% versus 73% (p < 0.01); comfort with vaccine counseling 92% versus 41%; comfort with vaccine administration 84% versus 22% (p < 0.01).Conclusion
Educating medical students and promoting the importance of vaccination early in a medical student's career using such an intervention is relatively simple and easily integrated into the curriculum. This intervention was successful in vaccinating all students, and demonstrated a marked positive shift in attitudes toward influenza vaccination. 相似文献5.

We surveyed the vaccination status of family physicians (FP) in the Loire district (France) in 2010.Subjects and methods
A self-administered questionnaire was proposed to a panel of 460 FP; 288 (64%) answered.Results
The vaccination coverage for Diphtheria-Tetanus-Polio in the previous 10 years, BCG, pertussis, seasonal influenza, A/H1N1 2009 influenza, and hepatitis B was 81, 74, 59, 73, 65, and 87% respectively. Sixty-four percent of FP reported they were vaccinated against measles and 49% against chicken pox; 76% were aware of vaccination recommendations for healthcare professionals but 41% wanted more information on the subject. The younger physicians were better vaccinated for Diphtheria-Tetanus-Polio, measles, hepatitis B, and influenza according to a multivariate analysis.Conclusions
The vaccinations of FP (knowledge, practice) must be improved, especially by yearly updates, continuous medical education, and medical follow-up of healthcare professionals. 相似文献6.

Objectives
We aim to describe influenza vaccination coverage for the Spanish population across four consecutive campaigns (2008/2009 to 2011/2012). The data was analyzed by high risk groups and health care workers (HCWs). Also, coverage trends were analyzed to assess uptake in post-pandemic seasons.Methods
We used data from two nation-wide representative health surveys namely the 2009/10 European Health Interview Survey for Spain (N = 22,188) and the 2011–12 Spanish National Health Survey (N = 21,007) Influenza vaccination status was self-reported. We analyzed influenza vaccine coverage by age, sex, number of chronic conditions, being a heath care worker (HCWs) and nationality. Time trends for campaigns among high risk groups were estimated by a multivariate logistic regression model.Results
We analyzed data from 43,072 subjects aged ≥16 years. As a whole, coverage decreased by 3.31% (22.57–19.26%) between the 2008/2009 and 2011/2012 campaigns with a significant decreasing trend (OR 0.92; 95% CI: 0.90–0.94).Coverage in people under 60 years with a chronic disease decreased significantly (OR 0.92: 95% CI: 0.85–0.99) during the analyzed period from 21.02% in 2008/2009 to 17.40% in 2011/2012. Among HCWs, the highest influenza vaccination coverage was achieved in 2009/2010 (31.08%) in the latest campaign coverage has almost halved (17.88%). For the 2011/2012 season and for all age groups the variables associated with a higher probability of having received the influenza vaccine were older age and presence of associated chronic conditions. Among those aged ≥60 years, immigrants had lower uptake (OR 0.60; 95% CI: 0.32–0.99).Conclusions
Seasonal influenza vaccine uptake rates in the recommended target groups in Spain are unacceptably low and seem to be decreasing in the post pandemic seasons. Further studies are necessary to precisely identify reasons for non-compliance and barriers to influenza vaccination. Meanwhile urgent strategies to improve seasonal vaccination uptake must be discussed and implemented. 相似文献7.

Objectives
To determine vaccination coverage against seasonal influenza and the new A (H1N1) influenza virus among healthcare personnel during the 2009-2010 season and to identify its determining factors.Methods
We performed a cross-sectional study among healthcare staff at the General University Hospital in Alicante (Spain) during the 2008-2009 and 2009-2010 influenza vaccination campaigns. The 2009-2010 vaccination campaign was subdivided into two phases. In the first phase, from 1st October to 19th November, 2009, the seasonal influenza vaccine was administered; in the second phase, from 16th November to 30th December, 2009, vaccination against the new A (H1N1) influenza virus was performed. Each of the vaccine programs was preceded by a specific vaccination promotion campaign. Healthcare staff were asked to complete a brief self-administered questionnaire containing a list of reasons for being vaccinated. Coverage during both vaccination campaigns was calculated, and the results, both overall and for each profession, were then compared using a Chi-square test.Results
Coverage against seasonal influenza was 31% and that against the new A (H1N1) influenza virus was 22.2% (p < 0.05); these percentages were 36% and 34% respectively in medical personnel (NS), 33% and 24% respectively in nursing personnel (p < 0.001), and 21% and 12% respectively in nursing assistants (p < 0.001). The main reason given for being vaccinated was self-protection.Conclusions
The low coverage achieved is a public health problem. Specific intervention programs should be implemented. 相似文献9.

In 2009, the Dutch government advised pregnant women to get vaccinated against influenza A (H1N1). A study was set up to gain insight into vaccination coverage and reasons why pregnant women seek vaccination or not.Methods
We invited 14,529 pregnant women to complete an internet survey on vaccination during pregnancy in general and against 2009 influenza A (H1N1). Differences in background characteristics between unvaccinated and vaccinated women were investigated. Prediction analyses were carried out to determine which survey statement had the greatest impact on vaccination status or intention to get vaccinated during pregnancy.Results
Of the 2993 included respondents, 63% reported to be vaccinated against 2009 influenza A (H1N1). Vaccination coverage was higher among older birth cohorts, women who had been pregnant before, women with underlying medical conditions, and women who reported no defined ‘life philosophy’. Protection of the child (after birth), the government's advice and possible harmful effects of the vaccine for the unborn child had the greatest predictive value for vaccination status. With regards vaccination during future pregnancies, 39% had a positive intention to obtain vaccination and 45% were neutral. The government's advice was the strongest predictor for intention. Furthermore, women expressed concern over lack of sufficient knowledge about vaccine safety.Conclusions
A considerable number of pregnant women in the Netherlands reported to be vaccinated against 2009 influenza A (H1N1). The challenge for the government in the future will be to provide pregnant women and health care professionals with sufficient and clear information about disease severity and the benefits and safety of vaccination. 相似文献10.

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11.
Introduction
Immunization guidelines from many countries recommend influenza vaccination of health care workers (HCW). However, influenza vaccination rates among HCW are universally low. To aid in designing effective immunization programs we reviewed the literature for studies reporting on (1) self-reported reasons of HCW regarding vaccination against influenza and (2) predictive factors for influenza vaccination in HCW.Methods
We searched PUBMED for relevant publications from 1980 to 2008 with predetermined search strategies and applied pre-defined criteria for inclusion or exclusion. To be included in the review as a predictor study, a multivariate analysis must have been conducted.Results
We included 25 studies relevant to self-reported reasons for rejecting or accepting vaccination. These studies identified two major reasons for lack of vaccine uptake by HCW: firstly, a wide range of misconceptions or lack of knowledge about influenza infection; and secondly, a lack of convenient access to vaccine. In contrast, among studies reporting on reasons for vaccination acceptance, all but two found that HCW stated self-protection was the most important reason. In the area of “predictive factors for influenza vaccination”, we included 13 studies. At least five of them identified the following three factors: previous receipt of influenza vaccine, belief in the vaccine's effectiveness, and older age.Conclusion
Our findings indicate that if HCW get immunized against influenza, they do so primarily for their own benefit and not for the benefit to their patients. Misconceptions about influenza and influenza vaccine could be improved by education, and organizational barriers could be bridged with sustainable, structural changes to allow flexible and workplace vaccine delivery. 相似文献12.

Introduction
Seasonal influenza is a viral transmissible infectious disease causing increased morbidity or mortality in frail subjects, especially those living in institutions. Measures to prevent the impact of infectious diseases were proposed based on the use of influenza vaccination among health-care professionals. We wanted to evaluate the acceptance of our institutional vaccination procedure initiated in 2005 and possible improvement.Methods
A questionnaire was sent in May 2007 to all health-care professionals (n = 730) to identify their current vaccine status in 2006 and their opinion concerning vaccination against influenza in 2007.Results
Subsequently, 369 (50.2%) responses were obtained. Amongst those responding, 31.7% were vaccinated in 2006, 77.8% using the institutional procedure. Also, 221 (87.7%) nonvaccinated health-care professionals indicated their position concerning influenza vaccination: 37% of them would accept the vaccination in 2007 (on the condition that our current institutional procedure be improved), 63% of them would refuse influenza vaccines in spite of any improvement.Conclusion
Our study emphasizes that the use of an adapted procedure for influenza vaccination among health-care professionals could improve vaccine coverage. It also emphasizes that a margin of those professionals are still reluctant to vaccination. 相似文献13.
Background
Knowledge and beliefs about influenza vaccine that differ across racial or ethnic groups may promote racial or ethnic disparities in vaccination.Objective
To identify associations between vaccination behavior and personal beliefs about influenza vaccine by race or ethnicity and education levels among the U.S. elderly population.Methods
Data from a national telephone survey conducted in 2004 were used for this study. Reponses for 3875 adults ≥65 years of age were analyzed using logistic regression methods.Results
Racial and ethnic differences in beliefs were observed. For example, whites were more likely to believe influenza vaccine is very effective in preventing influenza compared to blacks and Hispanics (whites, 60%; blacks, 47%, and Hispanics, 51%, p < 0.01). Among adults who believed the vaccine is very effective, self-reported vaccination was substantially higher across all racial/ethnic groups (whites, 93%; blacks, 76%; Hispanics, 78%) compared to adults who believed the vaccine was only somewhat effective (whites 67%; blacks 61%, Hispanics 61%). Also, vaccination coverage differed by education level and personal beliefs of whites, blacks, and Hispanics.Conclusions
Knowledge and beliefs about influenza vaccine may be important determinants of influenza vaccination among racial/ethnic groups. Strategies to increase coverage should highlight the burden of influenza disease in racial and ethnic populations, the benefits and safety of vaccinations and personal vulnerability to influenza disease if not vaccinated. For greater effectiveness, factors associated with the education levels of some communities may need to be considered when developing or implementing new strategies that target specific racial or ethnic groups. 相似文献14.

Objective
The main aim of this study was to determine how much staff at the Clermont-Ferrand university hospital, France, knew about influenza and its relation with the vaccinal rate. The other aim was to develop better-targeted information campaigns and prevention policy in the work place.Design
A self-administered questionnaire was sent to the 7601 salaried staff of the hospital in May 2005. The staff was asked to give details on socioprofessional characteristics, vaccinal status, and knowledge about the influenza virus (mode of transmission, contagiousness, measures of prevention, populations affected, mortality, vaccination schedule, and vaccination target populations). Multiple-choice questions on knowledge of influenza were scored according to the answer given.Results
The response rate was 26.5%. The 2011 completed questionnaires were representative of the working staff. They showed a positive correlation between the rate of vaccination and knowledge of influenza, with a 0.98 coefficient. They also showed that the staff was very largely unaware of population groups most at risk for influenza (1% of correct answers).Conclusions
Primary prevention campaigns will only be effective if the target population has a better awareness of the issues involved. This study highlights the areas in which knowledge was heterogeneous or inadequate, and the information that could be decisive in increasing vaccinal coverage among staff. This information should focus on modes of transmission, contagiousness, mortality, and above all on populations at risk. 相似文献15.
Introduction
A novel H1N1 vaccine was manufactured in response to the pandemic in 2009. This study describes the willingness to be vaccinated for H1N1 among healthcare workers (HCWs) in primary healthcare clinics with and without chronic medical conditions, their reasons for refusing vaccination and whether they sought additional information to make an informed decision for the vaccination.Materials and methods
An anonymous survey was conducted in November 2009 among all medical, nursing, allied health and operations HCWs in nine primary care clinics in Singapore. Participants were asked if they had any chronic medical conditions associated with influenza-related complications (example: asthma, stroke, heart disease, cancer, diabetes mellitus, renal disease), their perception towards vaccination for H1N1 and against seasonal influenza within the preceding 2 years.Results
The initial response rate was 80%, of which 711 (54.7%) of the completed surveys were analysed. Among the 711 respondents, 16.6% reported having at least 1 chronic disease. Asthma (10.8%), hypertension (10.4%) and dyslipidaemia (9.8%) were the main chronic conditions. Only 39.4% of respondents were willing to be vaccinated against H1N1. Males were 2.07 (95% CI 1.19-3.62) times more likely than females to receive the H1N1 vaccination; the 45-54 and 55+ years old were 2.12 (95% CI 1.06-4.24) and 2.44 (95% CI 1.13-5.27) times more willing than those below 25 years old; and those who considered accepting the seasonal influenza vaccine were 7.0 times more likely than those who did not (95%CI 4.48-10.92). The 2 principal barriers were “fear of side effects” and “unsure of vaccine's effectiveness”. Although 78% attended some H1N1-related talks, only 7% of all HCWs felt that they had sufficient information. Most wanted more information about the vaccine's safety profile and contraindications.Conclusion
Fewer than 40% of HCWs expressed willingness to receive the H1N1 vaccination, lower than past rates of influenza vaccine. HCWs in primary care clinics who had a chronic condition did not perceive themselves to be at higher risk of developing H1N1-related complications and were not more willing than the rest of the HCWs to accept H1N1 vaccination. Vaccine's side effects and effectiveness were the main concerns. Uptake of H1N1 vaccine may improve with targeted health information covering the vaccine's safety profile. 相似文献16.

Background
The use of intradermal vaccination or virosomal vaccines could increase protection against influenza among the vulnerable population of older adults. Studies assessing the comparative effectiveness of these two influenza vaccine types in this age group are lacking.Methods
We conducted a retrospective cohort study to estimate the comparative effectiveness of intradermal seasonal trivalent-influenza vaccine (TIV) delivered by a microneedle injection system and a virosomal-TIV intramuscularly delivered for prevention of influenza hospitalization in non-institutionalized adults aged ≥65 years. We obtained administrative data on immunization status and influenza hospitalization for the 2011–2012 influenza season, and used Cox regression models to assess comparative effectiveness. We estimated crude and adjusted (age, sex, comorbidity, pharmaceutical claims, recent pneumococcal vaccination and number of hospitalizations for all causes other than influenza between the previous and current influenza seasons) hazard ratios (HR).Results
Overall, 164,021 vaccinated subjects were evaluated. There were 127 hospitalizations for influenza among 62,058 subjects, contributing 914,740 person-weeks at risk in the virosomal-TIV group, and 133 hospitalizations for influenza among 101,963 subjects, contributing 1,504,570 person-weeks at risk in the intradermal-TIV group. The crude HR of intradermal-TIV relative to virosomal-TIV was 0.64 (95% confidence interval (CI): 0.50–0.81), and the adjusted Cox estimated HR was 0.67 (95% CI: 0.52–0.85).Conclusions
During the 2011–2012 influenza season the risk of hospitalization for influenza was reduced by 33% in non-institutionalized elderly adults who were vaccinated with intradermal-TIV compared with virosomal-TIV. 相似文献17.

Background
Pregnant women have an increased risk of complications from influenza. Influenza vaccination during pregnancy is considered effective and safe; however estimates of vaccine coverage are low. This study aimed to determine influenza vaccination coverage and factors associated with vaccine uptake in pregnant women in two Sydney-based health districts.Methods
A random sample of women who delivered a baby in a public hospital in Sydney and South-Western Sydney Local Health Districts between June and September 2012 were surveyed using a computer assisted telephone interviewing service.Results
Of the 462 participants (participation rate 92%), 116 (25%) reported receiving the influenza vaccine during their pregnancy. In univariate analysis, vaccination coverage varied significantly depending on antenatal care type, hospital of birth, and parity (p<0.05), but not for age category, highest level of education, country of birth, language spoken at home, or Aboriginal status. Women who received antenatal care through a general practitioner (GP) had 2.3 (95% CI 1.4–3.6) times the odds (unadjusted) of receiving the influenza vaccination than those who received their antenatal care through a public hospital. The main reason cited for vaccination was GP recommendation (37%), while non-recommendation (33%) and lack of knowledge (26%) were cited as main reasons for not receiving the vaccination. 30% of women recalled receiving a provider recommendation for the vaccination and these women had 33.0 times the odds (unadjusted) of receiving the vaccination than women who had not received a recommendation. In a multivariate model a provider recommendation was the only variable that was significantly associated with vaccination (OR 41.9; 95% CI 20.7–84.9).Conclusion
Rates of influenza vaccination during pregnancy are low. There is a significant relationship between healthcare provider recommendation for the vaccination and vaccine uptake. Increasing provider recommendation rates has the potential to increase coverage rates of influenza vaccination in pregnant women. 相似文献18.

Objective
A questionnaire was used on 44 public and private hospital physicians in Paris to evaluate their knowledge of and adherence to Vaccination Guidelines, three years after their introduction.Results
Eighty per cent of the physicians answered and 92.5% were aware of the vaccination guidelines but only 2 out of 4 respected the targeted vaccination in young adults even when the vaccine was available. A policy of pertussis vaccination was applied only in 12 institutions, but even in these, the rate of vaccinated healthcare workers remained low or was not documented.Conclusion
Pertussis is a potential risk to newborns not or partially vaccinated in France. Even if the vaccine is available, adherence to pertussis vaccination guidelines must be improved. Efforts should be made to better publicize and apply pertussis vaccination guidelines. 相似文献19.
Background
Mathematical models of disease transmission and vaccination typically assume that protective vaccine efficacy (i.e. the relative reduction in the transmission rate among vaccinated individuals) is equivalent to direct effectiveness of vaccine. This assumption has not been evaluated.Methods
We used dynamic epidemiological models of influenza and measles vaccines to evaluate the common measures of vaccine effectiveness in terms of both the protection of individuals and disease control within populations. We determined how vaccine-mediated reductions in attack rates translate into vaccine efficacy as well as into the common population measures of ‘direct’, ‘indirect’, ‘total’, and ‘overall’ effects of vaccination with examples of compartmental models of influenza and measles vaccination.Results
We found that the typical parameterization of vaccine efficacy using direct effectiveness of vaccine can lead to the underestimation of the impact of vaccine. Such underestimation occurs when the vaccine is assumed to offer partial protection to every vaccinated person, and becomes worse when the level of vaccine coverage is low. Nevertheless, estimates of ‘total’, ‘indirect’ and ‘overall’ effectiveness increase with vaccination coverage in the population. Furthermore, we show how the measures of vaccine efficacy and vaccine effectiveness can be correctly calculated.Conclusions
Typical parameterization of vaccine efficacy in mathematical models may underestimate the actual protective effect of the vaccine, resulting in discordance between the actual effects of vaccination at the population level and predictions made by models. This work shows how models can be correctly parameterized from clinical trial data. 相似文献20.
