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.
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3.
Background
Germany introduced routine varicella (V) vaccination in 2004. Due to a slightly increased risk of febrile convulsions after first-dose application of combined measles–mumps–rubella–varicella (MMRV) vaccine separate first-dose vaccinations with MMR and monovalent V vaccine were recommended in September 2011.Methods
We compared V and MMR vaccinations in paediatric practices from two surveillance regions (Munich and Würzburg) one year before and after the change in the recommendation.Results
A total of 1405/326 monthly reports were provided by a monthly average of 79/14 practices participating in Munich/Würzburg. V first-dose vaccinations (monovalent V or MMRV vaccine) declined by 12% in Munich (from 10.1 to 8.9 vaccinations per month and practice; p < 0.005) and by 4% in Würzburg (from 9.9 to 9.5; p = 0.620), respectively. First-dose vaccinations for MMR (MMR or MMRV vaccine) did not change significantly in both regions.Conclusion
Acceptance of V vaccination depends in part on the use of combination vaccine. 相似文献4.
Introduction
Healthcare personnel (HCP) are often under-vaccinated. The aim of this study was to evaluate occupational physicians’ potential role by assessing relations between their knowledge and attitudes regarding HCP vaccination and the extent to which official vaccination recommendations are communicated.Methods
Cross-sectional survey, n = 135 occupational physicians.Results
Occupational physicians who treat HCP recommend vaccinations more often to HCP when they have better knowledge of official vaccination recommendations and a more positive attitude towards vaccination compared to physicians with less such knowledge or a more negative attitude. The attitude towards vaccination most strongly affects whether occupational physicians recommend the measles, mumps, and rubella (MMR) vaccination: physicians with less positive attitudes recommend MMR to HCP in a more restricted way. A more positive attitude towards vaccination also relates to fewer misconceptions. Occupational physicians’ knowledge and attitude further influence the extent to which pregnant HCP receive vaccinations against influenza. Knowledge about official recommendations does not influence the recommendation of influenza vaccination for pregnant women.Conclusions
Reasons for vaccination gaps in HCP might have their roots in occupational physicians’ incomplete knowledge of vaccination recommendations. Attitudes, which are related to misperceptions, also influence which vaccinations are recommended to HCP. Official recommendations, and not personal attitudes and misconceptions, should guide occupational vaccination behavior. 相似文献5.
Background
Pertussis can cause severe illness and death in infants. Immunization of family members with the tetanus toxoid, reduced diphtheria toxoids, and acellular pertussis (Tdap) vaccine can decrease risk of pertussis infection among infants. A community pharmacy on a women's hospital campus implemented a Tdap vaccination pilot program.Objective
To investigate the rate of Tdap vaccination among close contacts of neonates in a women's hospital pharmacy and to assess the impact of a coordinated pharmacy and hospital Tdap vaccination program.Methods
The intervention entailed education from hospital staff who explained the risks of pertussis, advocated the benefits of vaccination, and encouraged family members to be vaccinated. In the on-site clinic or in the pharmacy, pharmacists administered vaccine to eligible patients. Rates of Tdap vaccinations in the intervention pharmacy with in-hospital vaccination were compared to comparison pharmacies without Tdap interventions.Results
In the pre-study period (December 2008–November 2010), there were 31 Tdap vaccinations administered at the intervention pharmacy (mean = 1.3/month); during the study period (December 2010–November 2012), 2045 Tdap vaccinations were administered (mean = 85.2/month). In four comparison hospital-campus pharmacies, there were 77 vaccinations (mean = 0.8/month) during the pre-study period and 817 vaccinations (mean = 8.5/month) during the study period. There were 155 vaccinations administered in 44 area-community pharmacies (mean = 0.1/month) during the pre-study period and 2930 (mean = 2.8/month) during the study period. The intervention pharmacy had the highest average monthly rate of change in Tdap volume from pre-study to study period (83.9), compared to comparison hospital-campus pharmacies (7.7, p < .001) and area-community pharmacies (2.7, p < .001). During the study period, the estimated Tdap vaccination coverage per live births was 8.1% in the intervention pharmacy versus 5.5% in the comparison hospital-campus pharmacies (p < .001).Conclusions
Tdap vaccination rates increased after implementation of the intervention program. This project illustrates how health systems and community pharmacists can collaborate to improve patient care. 相似文献6.

Objective
The aim of this study was to evaluate flu vaccination rates and influencing factors in patients with systemic inflammatory diseases.Methods
All patients presenting with a systemic inflammatory disease and taking immunosuppressants, who were hospitalized or had consulted in our internal medicine department between January 2 and 31, 2006, were included in the study. The information concerning flu vaccination was collected with a standardized form.Results
One hundred and thirty-seven patients (mean age 53.1 ± 17.6 years; 40 [29%] male patients) were included: 39 (28%) had received flu vaccination in 2005 including 14 (16.7%) of the 84 patients with no other indication for flu vaccination than IS-induced immunodepression and 25 (47.2%) of the 53 patients with other flu vaccination indication(s) (p < 0.001). The most frequent reasons for non-vaccination were: absence of physician recommendation (58%), fear of adverse effects (35%) and concern on vaccine clinical effectiveness (5%). The vaccination rate was significantly higher (49%) among patients who remembered having received a voucher from the French National Health Insurance Agency versus 18% among those who did not (OR = 4.2 [95%CI, 1.92–9.19] p < 0.05). This correlation remained significant after adjustment for confounding factors in a logistic regression model.Conclusion
Influenza-vaccination coverage is low in patients receiving immunosuppressive therapy for systemic inflammatory diseases. We have to increase the influenza-vaccination coverage in this population. 相似文献7.

Background
Roughly half of U.S. adults do not receive recommended booster vaccinations, but protective antibody levels are rarely measured in adults. Demographic factors, vaccination history, and responses to other vaccinations could help identify at-risk individuals. We sought to characterize rates of seroconversion and determine associations of humoral responses to multiple vaccinations in healthy adults.Methods
Humoral responses toward measles, mumps, tetanus toxoid, pertussis, hepatitis B surface antigen, and anthrax protective antigen were measured by ELISA in post-immunization samples from 1465 healthy U.S. military members. We examined the effects of demographic and clinical factors on immunization responses, as well as assessed correlations between vaccination responses.Results
Subsets of boosted adults did not have seroprotective levels of antibodies toward measles (10.4%), mumps (9.4%), pertussis (4.7%), hepatitis B (8.6%) or protective antigen (14.4%) detected. Half-lives of antibody responses were generally long (>30 years). Measles and mumps antibody levels were correlated (r = 0.31, p < 0.001), but not associated with select demographic features or vaccination history. Measles and mumps antibody levels also correlated with tetanus antibody response (r = 0.11, p < 0.001).Conclusions
Vaccination responses are predominantly robust and vaccine specific. However, a small but significant portion of the vaccinated adult population may not have quantitative seroprotective antibody to common vaccine-preventable infections. 相似文献8.

Background
In 2009 the pandemic influenza virus A(H1N1)pdm09 emerged with guidance that people at risk should be vaccinated. It is unclear how this event affected the underlying seasonal vaccination rate in subsequent years.Purpose
To investigate the association of pandemic influenza A(H1N1)pdm09 and seasonal flu vaccination status in 2009 with vaccination rates in 2010 and 2011.Methods
Data were collected in 40 Dutch family practices on patients at risk for influenza during 2009–2011; data analysis was conducted in 2012.Results
A multilevel logistic regression model (n = 41,843 patients) adjusted for practice and patient characteristics (age and gender, as well as those patient groups at risk), showed that people who were vaccinated against A(H1N1)pdm09 in 2009 were more likely to have been vaccinated in 2010 (OR 6.02; 95%CI 5.62–6.45, p < .0001). This likelihood was even more for people who were vaccinated against seasonal flu in 2009 (OR 13.83; 95%CI 12.93–14.78, p < .0001). A second analysis on the uptake rate in 2011 (n = 39,468 patients) showed that the influence of the vaccination state in 2009 declined after two years, but the diminishing effect was smaller for people vaccinated against A(H1N1)pdm09 than for seasonal flu (OR 5.50; 95%CI 5.13–5.90, p < .0001; OR 10.98; 95%CI 10.26–11.75, p < .0001, respectively).Conclusion
Being vaccinated against A(H1N1)pdm09 and seasonal influenza in the pandemic year 2009 enhanced the probability of vaccination in the next year and this was still effective in 2011. This suggests that peoples’ vaccination routines were not changed by the rumor around the outbreak of A(H1N1)pdm09, but rather confirmed underlying behavior. 相似文献9.

Background
Intervals longer than recommended are frequently encountered between doses of tick borne encephalitis virus (TBE) vaccines in both residents of and travelers to endemic regions. In clinical practice the management of individuals with lapsed TBE vaccination schedules varies widely and has in common that the underlying immunological evidence is scarce.Study purpose and methods
The aim of this study was to generate data reliable enough to derive practical recommendations on how to continue vaccination with FSME-IMMUN in subjects with an irregular TBE vaccination history. Antibody response to a single catch-up dose of FSME-IMMUN was assessed in 1115 adults (age ≥16 years) and 125 children (age 6–15 years) with irregular TBE vaccination histories.Results
Subjects of all age groups developed a substantial increase in geometric mean antibody concentration after a single catch-up TBE vaccination which was consistently lower in subjects with only one previous TBE vaccination compared to subjects with two or more vaccinations. Overall, >94% of young adults and children, and >93% of elderly subjects with an irregular TBE vaccination history achieved antibody levels ≥25 U/ml irrespective of the number of previous TBE vaccinations.Conclusion
We conclude that TBE vaccination of subjects with irregular vaccination histories should be continued as if the previous vaccinations had been administered in a regular manner, with the stage of the vaccination schedule being determined by the number of previous vaccinations. Although lapsed vaccination schedules may leave subjects temporarily with inadequate protection against TBE infection, adequate protection can quickly be re-established in >93% of the subjects by a single catch-up dose of FSME-IMMUN, irrespective of age, number of previous vaccinations, and time interval since the last vaccination. 相似文献10.

Background
Studies from Africa have suggested marked non-specific effects (NSEs) of routine vaccinations with effects on child survival. There have been few studies from Asia. We re-analyzed a study from Maharashtra, India, which had collected information on vaccinations during infancy and survival until 5 years of age.Design
4138 children born between 1987 and 1989 were visited at home every three months to collect information on nutritional status and vaccinations. Since nutritional status was a determinant of time to vaccinations, we adjusted for nutritional status in the analyzes of the association between vaccinations and mortality.Setting
45 contiguous villages in Shirur Administrative Block in Pune District.Main outcome measures
Mortality rate ratios (MRR) for different vaccination status groups.Results
The study area has male preferential treatment, but the female–male mortality ratio varied between age groups with different pre-dominant vaccines; it was high in the age group in which diphtheria–tetanus–pertussis (DTP) vaccine predominates and low in the age group in which measles vaccine (MV) is given. Children who followed the WHO recommended schedule of first BCG and then DTP vaccination were vaccinated earlier than other children (p < 0.01). Two-thirds of the children had received BCG and DTP out-of-sequence, i.e. BCG and DTP simultaneously or BCG after DTP. Children who received BCG and DTP simultaneously or BCG as most recent vaccination had significantly lower mortality than children having DTP as the most recent vaccination, the mortality rate ratio being 0.15 (0.03–0.70).Conclusions
BCG out-of-sequence may be associated with lower mortality than DTP as the most recent vaccination. Given the public health implications, this possibility should be tested in randomized trials. Excess female mortality may also be related to vaccination policy. 相似文献11.

Objective
The aim of this study was to compare the cost of vaccination for the Clermont-Ferrand University hospital (CHU) personnel and the cost of sick leave among vaccinated and non-vaccinated employees in 2003, 2004, and 2005.Design
The study included 7256 CHU staff (medical and non-medical personnel). The cost of sick leave was calculated on the basis of short-term disease (four to nine days) over the three months of the epidemic season in 2004, 2005, and 2006.Results
In 2005, the overall cost of vaccination was 4.02 € per vaccinated employee. Over the three years, the total sick leave reached 804 days for employees vaccinated against 5670 for non-vaccinated employees. In 2003, 2004, and 2005, the vaccinal coverage was 13, 20.5, and 30.1%, the mean duration of sick leave was 0.16, 0.17, and 0.18 day among vaccinated staff, and 0.26, 0.39, and 0.34 day among non-vaccinated staff corresponding to a benefit per vaccinated employee of 5, 26, and 20 €, respectively for each year. The total benefit for the institution was 86,458 € (4630 + 38,168 + 43,660). If the vaccinated rate of 75% recommended by the Haute Autorité de santé (HAS) had been reached, the additional benefit would have been 250,193 € (33,157 + 152,256 + 65,180).Conclusions
The number of sick leave days and the related cost were approximately twice less important for vaccinated employees, economically justifying this vaccination including a period of weak epidemic, as checked over three consecutive years. 相似文献12.
Objective
Millions of children in North America receive an annual flu vaccination, many of whom are at risk of experiencing severe distress. Millions of children also use technologically advanced devices such as computers and cell phones. Based on this familiarity, we introduced another sophisticated device – a humanoid robot – to interact with children during their vaccination. We hypothesized that these children would experience less pain and distress than children who did not have this interaction.Method
This was a randomized controlled study in which 57 children (30 male; age, mean ± SD: 6.87 ± 1.34 years) were randomly assigned to a vaccination session with a nurse who used standard administration procedures, or with a robot who was programmed to use cognitive-behavioral strategies with them while a nurse administered the vaccination. Measures of pain and distress were completed by children, parents, nurses, and researchers.Results
Multivariate analyses of variance indicated that interaction with a robot during flu vaccination resulted in significantly less pain and distress in children according to parent, child, nurse, and researcher ratings with effect sizes in the moderate to high range (Cohen's d = 0.49–0.90).Conclusion
This is the first study to examine the effectiveness of child–robot interaction for reducing children's pain and distress during a medical procedure. All measures of reduction were significant. These findings suggest that further research on robotics at the bedside is warranted to determine how they can effectively help children manage painful medical procedures. 相似文献13.

Background
Timely vaccination, i.e., the receipt of all scheduled vaccinations in an age-appropriate fashion, is critical for the prevention of deadly diseases in infants and achievement of the UN Millennium Development Goal to reduce infant mortality. Infants, especially in rural or underprivileged settings often receive delayed vaccinations leaving them susceptible to vaccine-preventable illnesses early in the first year of life. In this study, we examined rates of timely vaccination among 24,435 infants born in Gaibandha and Rangpur rural districts of Bangladesh from 2001 to 2007.Methods
Vaccinations due by 14 weeks of age and administered through routine government immunization services were assessed using interviews with enrolled mothers between 11 and 18 weeks postpartum. We created a Timely Vaccination (TV) score to classify infants as vaccinated fully and on schedule (TV = 1) or not (TV = 0), and used multivariable logistic regression to identify maternal characteristics associated with infant's timely vaccination status.Results
Our results suggest that only 19% of infants in this cohort received scheduled vaccinations on time by 11–18 weeks postpartum. Mothers’ engagement in paid employment [OR = 1.13, 95% CI: 1.03–1.23], receipt of tetanus toxoid vaccination [OR = 1.24, 95% CI: 1.11–1.38], history of antenatal care [OR = 1.22, 95% CI: 1.12–1.32], or higher socioeconomic status [OR = 1.07, 95% CI: 1.03–1.11] were positively associated with timely vaccination of their infants. Mother's perception of small infant size at birth was negatively associated with timely vaccination [OR = 0.89, 95% CI: 0.82–0.97].Conclusion
Timely vaccination coverage of infants in rural Gaibandha and Rangpur districts is extremely low. This analysis identifies important shortcomings associated with the 1-year vaccination benchmark of routine immunization performance and suggests the need for specific interventions based on potential maternal determinants as well as known system and programmatic barriers of timely vaccination among infants in rural Bangladesh. 相似文献14.
Objectives
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15.
Objectives
Hepatitis A (HAV) and Hepatitis B (HBV) infections can cause serious morbidity in patients with liver disease, including cystic fibrosis associated liver disease (CFALD). HAV and HBV vaccinations are recommended in CFALD, and maintenance of detectable antibody levels is also recommended with chronic liver disease. A better understanding of factors predicting low HAV and HBV antibodies may help physicians improve protection from these viruses in CFALD patients.Methods
We examined HAV and HBV vaccine protection in children at risk for CFALD. Clinical and vaccine histories were reviewed, and HAV and HBV antibody titers measured. Those with no vaccination history or low HAV or HBV titers received primary or booster vaccinations, and responses were measured.Results
Thirty-four of 308 children were at risk for CFALD per project criteria. Ten had previous HAV vaccination, of which 90% had positive anti-HAV antibodies. Thirty-three of 34 had previously received primary HBV vaccination (most in infancy), but only 12 (35%) had adequate anti-HBs levels (≥10 mIU/mL). Children with adequate anti-HBs levels were older at first HBV vaccine (median 2.3 vs. 0.1 years, p < 0.01), and at final HBV vaccine (median 4.0 vs. 0.8 years, p = 0.01). Fourteen of 19 (74%) responded to HBV boosters. Z-scores for BMI at HBV booster were significantly lower in booster non-responders (p = 0.04).Conclusions
Children at increased risk of CFALD have inadequate HAV and HBV antibody levels, and HBV antibody protection can be enhanced through vaccine boosters. HBV antibody titers should be assessed in CFALD patients with a history of vaccination, particularly in those who received HBV vaccines in infancy or who are malnourished. 相似文献16.
Objective
This study identifies factors that influence repeated influenza vaccination among people aged 65 years and older in Taiwan.Methods
Data of this retrospective cohort study were drawn from the 2005 National Health Interview Survey and the 2005–2007 National Health Insurance claims data; a sample of 1384 older people was analyzed. The pattern of repeated influenza vaccination was divided into 3 groups: unvaccinated all 3 years, vaccinated 1–2 times over 3 years, and vaccinated all 3 years. Multinomial logistic regression analyses were performed.Results
Only 20.6% of older people were vaccinated all 3 years. Those 70–74 years of age (odds ratio [OR] = 1.81), living in rural areas (OR = 2.47), having one (OR = 2.07) or more (OR = 2.41) chronic conditions, frequent outpatient visits (OR = 1.48), and undergoing preventive health examinations (OR = 2.22) were more likely to have repeated vaccinations. However, those with difficulties performing one or more activities of daily living (ADL difficulty) (OR = 0.41) and seeking care from alternative medicine (OR = 0.48) were less likely to undergo regular vaccinations.Conclusion
The repeated influenza vaccination rates in our Taiwan sample were far from optimal. Factors identified in this analysis may help to improving influenza vaccination programs. 相似文献17.

Background
Elderly patients with chronic obstructive pulmonary disease (COPD) are at a higher risk of hospitalization for cardiovascular complications, especially during respiratory infections. Previous studies showed that vaccination for influenza may reduce the risk of recurrent major cardiovascular events in patients with acute coronary syndrome (ACS). The purpose of this study was to evaluate the hypothesis that influenza vaccination could reduce hospitalizations for ACS in elderly patients with COPD.Method
Using the Taiwan Longitudinal Health Insurance Database 1996–2008, this cohort study comprised elderly patients (≥55 years old) with a recorded diagnosis of COPD (n = 7722) between January 1, 2000 and December 31, 2007. Each patient was followed until the end of 2007. A propensity score was derived by using a logistic regression model to reduce vaccine therapy selection bias. The hazard ratio (HR) and 95% confidence interval (CI) for the association between the influenza vaccination and the occurrence of first hospitalization for ACS in elderly COPD patients was examined by Cox proportional hazards regression analysis. In addition, we categorized the patients into four groups according to vaccination status (unvaccinated, total number of vaccinations: 1, 2−3, and ≥4).Results
We found that elderly patients with COPD receiving influenza vaccination had a lower risk of hospitalization for ACS (adjusted HR = 0.46, 95% CI (0.39–0.55), p < 0.001). We observed similar protective effects in both sexes and all age groups (55−64, 65−74, ≥75) regardless of influenza seasonality. When the patients were stratified according to the total number of vaccinations, the adjusted HRs for hospitalization because of ACS were 0.48 (0.38−0.62) and 0.20 (0.14−0.28) for patients who received 2−3 and ≥4 vaccinations during the follow-up period.Conclusion
Our data showed that there was a lower risk of ACS hospitalization in elderly patients with COPD receiving annual influenza vaccination. 相似文献18.

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. 相似文献19.

Background
Data on long-term response rates after successful primary hepatitis B (HBV) vaccination in HIV-infected patients are scarce.Objective
To evaluate the durability of an effective anti-HBs titer up to 5 years after primary vaccination in a cohort of 155 HIV-infected adults.Methods
From a previous multicenter HBV vaccination trial we selected patients with an anti-HBs titer of ≥10 IU/l 28 weeks after the first vaccination. The anti-HBs titer was measured in annually stored plasma samples up to 5 years after vaccination. Patients with decreasing anti-HBs titers <10 IU/I were defined as transient responders (TR*) and with persistent anti-HBs titers ≥10 IU/I as long-term responders (LTR^).Results
We included 155 patients, 87 were TR and 68 LTR. Mean age, percentage of female participants and duration of HAART use at primary vaccination were similar in LTR and TR. Anti-HBs level after primary vaccination was the strongest predictor for the durability of anti-HBs. Anti-HBs >100–1000 IU/I and >1000 resulted in an OR 8.3, 95% CI 3.38–20.16; p < 0.0001 and OR 75.6, 95% CI 13.41–426.45; p < 0.0001 versus anti-HBs titer of 10–100 IU/I after primary vaccination respectively. The mean time to loss of an effective anti-HBs titer was 2.0, 3.7 and 4.4 years respectively, for patients with an anti-HBs titer of 10–100 IU/I, >100–1000 IU/I and >1000 IU/I at primary vaccination. An undetectable HIV-RNA load and use of HAART during vaccination and at follow-up were, though not significantly, associated a higher long-term persistence of an effective antibody titer.Conclusion
The durability of an effective anti-HBs level appears to be significantly related to the height of the antibody titers after the primary immunization procedure. Schedules to improve the vaccination response in HIV-infected patients therefore seem to be justified. Whether a HBV booster is indicated remains to be elucidated. 相似文献20.
