[PMID: 38503662 DOI: 10.1016/j.vaccine.2024.03.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 03/02/2024] [Accepted: 03/14/2024] [Indexed: 03/21/2024]
Abstract
INTRODUCTION Healthcare workers are more likely to contract measles than the general population. Our study aimed to assess measles vaccination and immunization levels among nurses, examine the influencing factors and implement an intervention program to increase immunization coverage. MATERIALS AND METHODS Our study was conducted in a university hospital in Türkiye. The study included 1012 nurses. It was an intervention study, continued between 01/11/2021 and 30/10/2023. Measles IgG and vaccination status of the participants were evaluated. Participants with negative measles IgG results who had not been vaccinated against measles or received a single dose of the vaccine were invited to the outpatient clinic to receive two doses. Participants who had received two doses of the measles vaccine and had negative measles IgG results were invited to the outpatient clinic for one dose of the measles vaccine. Nine hundred seventy-eight people participated in our study. The access frequency was 96.6%. RESULTS Among the participants aged 21-30, 68.4 % were Measles IgG (+). Measles IgG (+) prevalence was higher in women than men (85.3 % vs. 61.0 %). The department with the lowest measles IgG positivity was intensive care (75.8 %). Measles IgG (+) prevalence became higher as the duration of employment increased. The measles seropositivity in total population rose from 83.1 % before the intervention to 94.3 % after, to 91.8 % in the 21-30 age group, and to 90.2 % in male. Sixteen people had never received measles vaccination. Of the 37 participants who had previously received two doses of measles vaccine, 22 received a single dose and after the intervention 16 (72.7 %) were positive. Only 1 person was found to have vaccine refusal during the intervention. CONCLUSION Expanding the immunization scope in hospitals by screening for measles antibodies among healthcare personnel and vaccinating those who are seronegative can be considered an effective public health strategy.

Vaccine 2023:S0264-410X(23)00664-3. [PMID: 37349224 DOI: 10.1016/j.vaccine.2023.06.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Accepted: 06/02/2023] [Indexed: 06/24/2023]
Abstract
OBJECTIVE To examine the seroprevalence of measles and varicella zoster virus (VZV) among healthcare workers (HCW) and evaluate the concordance between self-reported history of previous disease or vaccination and seropositivity. DESIGN A seroprevalence study and survey. SETTING A university-affiliated tertiary care hospital. PARTICIPANTS All HCWs working in high-risk services in 2017 underwent serologic tests and survey; all new HCWs employed in the subsequent years, serologic tests only. METHODS A serologic study was conducted using chemiluminescence immunoassay (2017) or enzyme immunoassays (2018 and later). HCWs who underwent serological testing in 2017 completed a self-administered questionnaire on their history of infection and vaccination. RESULTS A total of 10,278 and 9607 HCWs underwent serologic tests for measles and VZV IgG, respectively, from 2017 to 2022. The overall seropositivity rates for measles and VZV were 78.1 % and 92.8 %, respectively. Measles seropositivity declined gradually from >90 % in the HCWs born in the 1960s to <80 % in those born in the 1990s. There was a significant difference in measles seropositivity between the birth cohorts (BCs) 1967-1984 and 1985-1999 (P < 0.001; odds ratio, 1.16; 95 % confidence interval, 1.14-1.18). The seropositivity for VZV was stable, at >90 % in all BCs. The self-reported vaccination history was not independently associated with seropositivity, and the negative predictive value of the survey was very low (9.6 % and 13.1 %, respectively). CONCLUSIONS Measles seropositivity showed a substantial decline among HCWs born in 1985 or later, while varicella seropositivity remained high. The self-reported vaccination history was not sufficiently reliable for screening HCWs.

Abstract
Life-course immunization holds significant benefit for population health by reducing the burden of vaccine-preventable diseases (VPD) through vaccinating individuals at different stages and circumstances in life. The study aimed to determine the epidemiologic, clinical, economic, and societal burden of VPDs among at-risk adult subpopulations in the United States. A systematic literature review was conducted for articles published between January 2010 and June 2020, which identified 72 publications. There was heterogeneity in available epidemiology data, with the prevalence of VPDs ranging from 1.1% to 68.7%. Where the disease burden was described, outcomes were typically worse among high-risk subpopulations than in the general population. Several VPDs, including herpes zoster, meningococcal, and pneumococcal infections were associated with increased costs. This review suggests that subpopulations may not frequently interact with the healthcare system, or their risk factors may not be recognized by healthcare providers, and therefore individuals may not be appropriately targeted for vaccination.

The Clinical and Economic Impact of Measles-Mumps-Rubella Vaccinations to Prevent Measles Importations From US Pediatric Travelers Returning From Abroad. J Pediatric Infect Dis Soc 2022; 11:257-266.

Abstract
BACKGROUND Pediatric international travelers account for nearly half of measles importations in the United States. Over one third of pediatric international travelers depart the United States without the recommended measles-mumps-rubella (MMR) vaccinations: 2 doses for travelers ≥12 months and 1 dose for travelers 6 to <12 months. METHODS We developed a model to compare 2 strategies among a simulated cohort of international travelers (6 months to <6 years): (1) No pretravel health encounter (PHE): travelers depart with baseline MMR vaccination status; (2) PHE: MMR-eligible travelers are offered vaccination. All pediatric travelers experience a destination-specific risk of measles exposure (mean, 30 exposures/million travelers). If exposed to measles, travelers' age and MMR vaccination status determine the risk of infection (range, 3%-90%). We included costs of medical care, contact tracing, and lost wages from the societal perspective. We varied inputs in sensitivity analyses. Model outcomes included projected measles cases, costs, and incremental cost-effectiveness ratios ($/quality-adjusted life year [QALY], cost-effectiveness threshold ≤$100 000/QALY). RESULTS Compared with no PHE, PHE would avert 57 measles cases at $9.2 million/QALY among infant travelers and 7 measles cases at $15.0 million/QALY among preschool-aged travelers. Clinical benefits of PHE would be greatest for infants but cost-effective only for travelers to destinations with higher risk for measles exposure (ie, ≥160 exposures/million travelers) or if more US-acquired cases resulted from an infected traveler, such as in communities with limited MMR coverage. CONCLUSIONS Pretravel MMR vaccination provides the greatest clinical benefit for infant travelers and can be cost-effective before travel to destinations with high risk for measles exposure or from communities with low MMR vaccination coverage.

Abstract
During the measles epidemic in 2019, in-hospital transmission of measles contributed to more than two-thirds of measles cases in South Korea, where measles is declared eliminated. This study aimed to examine measles seropositivity among healthcare workers (HCWs) in South Korea to help develop an effective measles prevention strategy for hospital settings. Measles IgG titer was tested in 1,579 HCWs working in a university-affiliated hospital and the measles-containing vaccine (MCV) immunization records of 870 HCWs were identified. The overall seropositivity was 92.0%, but the seropositivity and antibody titers were significantly low among HCWs aged 20-25 years (78.6%) and among one-dose vaccine recipients (86.7%). Among two-dose recipients, seropositivity was lower among young HCWs who received two doses during their childhood than among those who received the catch-up vaccination as part of job requirements (70.3% vs. 98.0%). Among 87 seronegative HCWs who received two-dose MMR vaccination, the seroconversion rate was 98.9%. A considerable proportion of young HCWs were potentially susceptible to measles despite receiving the two-dose vaccination during childhood because of the waning immunity against measles in a country with measles-eliminated status. Serological screening for measles of newly employed HCWs and MCV immunization of seronegative HCWs appears to be an effective prevention strategy.

Abstract
Preventing occupational health exposures in the emergency room. Prompt isolation of infectious patients. Performance Improvement project to prevent disease transmission.
Background Preventing respiratory infectious disease exposures is a performance improvement project to reduce the incidence of occupational health exposures among health care workers. This project encouraged registered nurses to quickly identify and isolate potentially infectious patients in the emergency room, to prevent exposures to airborne and droplet transmitted communicable diseases, including meningitis, tuberculosis, and measles. Methods This pre- and postintervention model implemented a quasi-experimental designed project in the emergency room (ER). The Centers for Disease Control's empiric transmission-based isolation precautions were implemented to prevent occupational health exposures. Eighty registered nurses (RN's) received education on the new intervention. The assumption of this project was, the new process will decrease occupational health exposures. Results Eight ER RNs reported an occupational health exposure, preintervention in quarter 2 of 2019, compared to zero occupational health exposures, postintervention in quarter 3 of 2019. A χ² independence test was used to determine if the categorical variables of the capstone intervention and disease exposure were related in the same RN population. An association between the capstone intervention and disease exposure was observed, X2 (1) = 8.421, P = .004, indicating the result is statistically significant. Conclusions The preventing respiratory infectious disease exposures project effectively reduced occupational health exposures to airborne and droplet transmitted diseases in the emergency room by 100%. These results should encourage Infection Preventionists to adapt the Centers for Disease Control's empiric transmission isolation precautions in their emergency rooms and urgent cares to prevent airborne and droplet transmitted disease exposures.

A cross-sectional survey of measles preparedness in critical-access hospitals of Idaho. Am J Infect Control 2020; 48:795-797.

Abstract
BACKGROUND Patients with measles can precipitate outbreaks in health care facilities where they seek care. Rural critical-access hospitals (CAHs) may be at higher risk of outbreaks given their size and potentially limited infection prevention resources. METHODS We surveyed CAHs in Idaho to ascertain their levels of preparedness for managing measles cases. A 25-item questionnaire was sent to infection preventionists at all 27 Idaho CAHs. The questionnaire covered organizational structure, resources for managing measles cases, and hospital policies for ensuring immunity among health care workers. RESULTS A total of 22 (82%) CAHs responded, reporting varying availability of facilities and resources for managing measles cases and disparate procedures for testing clinical samples and providing vaccines to nonimmune, exposed staff. DISCUSSION With measles incidence on the rise in the United States, our survey found that most of the responding hospitals had the basic organizational structure for facility-wide prevention and management efforts in case a patient with suspected or confirmed measles presented to that facility. Most of the hospitals also had at least some available resources to manage measles cases, as well as policies for ensuring immunity to measles among at least some groups of health care workers. CONCLUSIONS This study provides initial perspectives on measles preparedness among Idaho CAHs, despite limited generalizability. Future studies should explore whether self-reported preparedness measures reflect the ability of the CAHs to control measles spread when cases present for care.

Abstract
INTRODUCTION Endemic measles persists in China, despite >95% reported coverage of two measles-containing vaccine doses and nationwide campaign that vaccinated >100 million children in 2010. An increasing proportion of infections now occur among adults and there is concern that persistent susceptibility in adults is an obstacle to measles elimination in China. We performed a case-control study in six Chinese provinces between January 2012 to June 2013 to identify risk factors for measles virus infection and susceptibility among adults. METHODS Persons ≥15 years old with laboratory-confirmed measles were age and neighborhood matched with three controls. Controls had blood specimens collected to determine their measles IgG serostatus. We interviewed case-patients and controls about potential risk factors for measles virus infection and susceptibility. Unadjusted and adjusted matched odds ratios and 95% confidence intervals (CIs) were calculated via conditional logistic regression. We calculated attributable fractions for infection for risk factors that could be interpreted as causal. RESULTS 899 cases and 2498 controls were enrolled. Among controls, 165 (6.6%) were seronegative for measles IgG indicating persistent susceptibility to infection. In multivariable analysis, hospital visit and travel outside the prefecture in the prior 1-3 weeks were significant risk factors for measles virus infection. Occupation and reluctance to accept measles vaccination were significant risk factors for measles susceptibility. The calculated attributable fraction of measles cases from hospital visitation was 28.6% (95% CI: 20.6-38.8%). CONCLUSIONS Exposure to a healthcare facility was the largest risk factor for measles virus infection in adults in China. Improved adherence to hospital infection control practices could reduce risk of ongoing measles virus transmission and increase the likelihood of achieving and sustaining measles elimination in China. The use of control groups stratified by serological status identified distinct risk factors for measles virus infection and susceptibility among adults.

Abstract
BACKGROUND Healthcare personnel (HCP) are at risk of being exposed to or transmitting infections in hospitals, and vaccination against vaccine-preventable diseases (VPDs) is a well-known preventive strategy. Vaccination against influenza, hepatitis B virus, measles-mumps-rubella, varicella, and pertussis is recommended for HCP. However, there is no information on the current status of hospitals' vaccination policies for HCP in Korea. METHODS We conducted a nationwide survey on hospital vaccination policies and barriers to implementing recommended vaccination programs in 2018. The online survey questionnaire was distributed to 652 hospitals, and 200 of them responded. RESULTS Of the 200 surveyed hospitals, 151 (75.5%) conducted a pre-employment screening program for at least one VPD, and 196 (98%) had vaccination programs that included at least one vaccine. Influenza vaccine was most commonly included in their programs (97.5%, n = 195), followed by hepatitis B vaccines (69%, n = 138). However, < 25% of the hospitals included other vaccines in their policies (measles-mumps-rubella, 24.5%; varicella, 18.5%; pertussis, 11%). Only 13 hospitals (6.5%) included the five recommended vaccines for HCP in their policies. Influenza vaccination coverage had a mean of 89.9% and was significantly higher in hospitals fully funding the vaccination cost (91.8% vs. 80.4%, P < 0.001). Among hospitals funding influenza vaccines, the coverage was lower in hospitals with ≥ 700 beds (-6.5%, P = 0.003). Hospitals' financial burden was the most important barrier to implementing vaccination polices as recommended (78.6%, 121/154), followed by lack of awareness (21%) or campaign (21%) and lack of leadership (17%). CONCLUSION Despite the recommendations on vaccination for HCP, the vaccination policies for HCP differ in hospitals and appear to be insufficient to protect HCP and prevent nosocomial transmission. Strong leadership of each hospital to protect HCP and financial support from the government are required to implement appropriate vaccination policies in hospitals.

Abstract
PURPOSE OF REVIEW Familial hypercholesterolemia has long been considered a monogenic disorder. However, recent advances in genetic analyses have revealed various forms of this disorder, including polygenic and oligogenic familial hypercholesterolemia. We review the current understanding of the genetic background of this disease. RECENT FINDINGS Mutations in multiple alleles responsible for low-density lipoprotein regulation could contribute to the development of familial hypercholesterolemia, especially among patients with mutation-negative familial hypercholesterolemia. In oligogenic familial hypercholesterolemia, multiple rare genetic variations contributed to more severe familial hypercholesterolemia. SUMMARY Familial hypercholesterolemia is a relatively common 'genetic' disorder associated with an extremely high risk of developing coronary artery disease. In addition to monogenic familial hypercholesterolemia, different types of familial hypercholesterolemia, including polygenic and oligogenic familial hypercholesterolemia, exist and have varying degrees of severity. Clinical and genetic assessments for familial hypercholesterolemia and clinical risk stratifications should be performed for accurate diagnosis, as should cascade screening and risk stratification for the offspring of affected patients.

Public health responses during measles outbreaks in elimination settings: Strategies and challenges. Hum Vaccin Immunother 2018; 14:2222-2238.

Abstract
In late September 2016, the Americas became the first region in the world to have eliminated endemic transmission of measles virus. Several other countries have also verified measles elimination, and countries in all six World Health Organization regions have adopted measles elimination goals. The public health strategies used to respond to measles outbreaks in elimination settings are thus becoming relevant to more countries. This review highlights the strategies used to limit measles spread in elimination settings: (1) assembly of an outbreak control committee; (2) isolation of measles cases while infectious; (3) exclusion and quarantining of individuals without evidence of immunity; (4) vaccination of susceptible individuals; (5) use of immunoglobulin to prevent measles in exposed susceptible high-risk persons; (6) and maintaining laboratory proficiency for confirmation of measles. Deciding on the extent of containment efforts should be based on the expected benefit of reactive interventions, balanced against the logistical challenges in implementing them.

Abstract
Control of measles was the focus of a national workshop held in 2015 in Sydney, Australia, bringing together stakeholders in disease control and immunisation to discuss maintaining Australia's measles elimination status in the context of regional and global measles control. The global epidemiology of measles was reviewed, including outbreaks in countries that have achieved elimination, such as the Disneyland outbreak in the United States and large outbreaks in Sydney, Australia. Transmission of measles between Australia and New Zealand occurs, but has not been a focus of control measures. Risk groups, the genetic and seroepidemiology of measles as well as surveillance, modelling and waning vaccine-induced immunity were reviewed. Gaps in policy, research and practice for maintaining measles elimination status in Australia were identified and recommendations were developed. Elimination of measles globally is challenging because of the infectiousness of measles and the need for 2-dose vaccine coverage rates in excess of 95% in all countries to achieve it. Until this occurs, international travel will continue to permit measles importation from endemic countries to countries that have achieved elimination. When measles cases are imported, failure to diagnose and isolate cases places the health system at risk of measles outbreaks. Vaccine funding models can result in gaps in vaccine coverage for adults and migrants. Australia introduced a whole-of-life immunisation register in 2016 and catch-up vaccination for at-risk communities, which will improve measles control. Research on diagnosis, immunology, case management and modelling of vaccination strategies are important to ensure continued control of measles.

Abstract
Les infections associées aux soins (IAS) constituent un véritable problème de santé publique. Escherichia coli, Staphylococcus aureus, Clostridium difficile sont les plus souvent à l’origine des IAS. L’antibiorésistance fréquente complique encore la prise en charge et des impasses thérapeutiques existent à présent. Les mesures d’hygiène hospitalière bien qu’essentielles sont insuffisantes pour diminuer drastiquement les IAS. Ainsi, des stratégies alternatives à l’antibiothérapie s’avèrent nécessaires pour prévenir et traiter les IAS. Parmi celles-ci, la vaccination et l’immunisation passive sont probablement les plus prometteuses. Nous avons fait une mise au point sur les vaccins disponibles et en développement clinique pour lutter contre les IAS, chez les patients à risque d’IAS et les soignants. L’intérêt de la vaccination grippale et rotavirus chez les patients pour prévenir ces IAS virales a été examiné. Le développement d’un vaccin anti-S. aureus, déjà émaillé de 2 échecs est complexe. Toutefois, ces échecs ont permis d’améliorer les connaissances sur l’immunité anti-S. aureus. La mise à disposition d’un vaccin préventif anti-C. difficile semble plus proche. Pour les autres bactéries gram négatif responsables d’IAS, le développement est moins avancé. La vaccination des patients à risques d’IAS pose également des problèmes de réponse vaccinale qu’il faudra résoudre pour utiliser cette stratégie. Ainsi, la vaccination des soignants, de par l’effet de groupe permet également de prévenir les IAS. Nous faisons ici le point sur l’intérêt de la vaccination des soignants contre la rougeole, la coqueluche, la grippe, la varicelle, l’hépatite B pour réduire les IAS avec des vaccins déjà disponibles.

Abstract
Background Measles outbreaks continue to occur in the United States and are mostly due to infections in returning travelers. Objective To describe how providers assessed the measles immunity status of departing U.S. adult travelers seeking pretravel consultation and to assess reasons given for nonvaccination among those considered eligible to receive the measles, mumps, rubella (MMR) vaccine. Design Observational study in U.S. pretravel clinics. Setting 24 sites associated with Global TravEpiNet (GTEN), a Centers for Disease Control and Prevention-funded consortium. Patients Adults (born in or after 1957) attending pretravel consultations at GTEN sites (2009 to 2014). Measurements Structured questionnaire completed by traveler and provider during pretravel consultation. Results 40 810 adult travelers were included; providers considered 6612 (16%) to be eligible for MMR vaccine at the time of pretravel consultation. Of the MMR-eligible, 3477 (53%) were not vaccinated at the visit; of these, 1689 (48%) were not vaccinated because of traveler refusal, 966 (28%) because of provider decision, and 822 (24%) because of health systems barriers. Most MMR-eligible travelers who were not vaccinated were evaluated in the South (2262 travelers [65%]) or at nonacademic centers (1777 travelers [51%]). Nonvaccination due to traveler refusal was most frequent in the South (1432 travelers [63%]) and in nonacademic centers (1178 travelers [66%]). Limitation These estimates could underrepresent the opportunities for MMR vaccination because providers accepted verbal histories of disease and vaccination as evidence of immunity. Conclusion Of U.S. adult travelers who presented for pretravel consultation at GTEN sites, 16% met criteria for MMR vaccination according to the provider's assessment, but fewer than half of these travelers were vaccinated. An increase in MMR vaccination of eligible U.S. adult travelers could reduce the likelihood of importation and transmission of measles virus.

Abstract
BACKGROUND Measles, a vaccine-preventable disease that can cause severe complications, was declared eliminated from the United States in 2000. The last published summary of US measles epidemiology was during 2001-2008. We summarized US measles epidemiology during 2009-2014. METHODS We compared demographic, vaccination, and virologic data on confirmed measles cases reported to the Centers for Disease Control and Prevention during January 1, 2009-December 31, 2014 and January 1, 2001-December 31, 2008. RESULTS During 2009-2014, 1264 confirmed measles cases were reported in the United States, including 275 importations from 58 countries and 66 outbreaks. The annual median number of cases and outbreaks during this period was 130 (range, 55-667 cases) and 10 (range, 4-23 outbreaks), respectively, compared with an annual median of 56 cases (P = .08) and 4 outbreaks during 2001-2008 (P = .04). Among US-resident case-patients during 2009-2014, children aged 12-15 months had the highest measles incidence (65 cases; 8.3 cases/million person-years), and infants aged 6-11 months had the second highest incidence (86 cases; 7.3 cases/million person-years). During 2009-2014, 865 (74%) of 1173 US-resident case-patients were unvaccinated and 188 (16%) had unknown vaccination status; of 917 vaccine-eligible US-resident case-patients, 600 (65%) were reported as having philosophical or religious objections to vaccination. CONCLUSIONS Although the United States has maintained measles elimination since 2000, measles outbreaks continue to occur globally, resulting in imported cases and potential spread. The annual median number of cases and outbreaks more than doubled during 2009-2014 compared with the earlier postelimination years. To maintain elimination, it will be necessary to maintain high 2-dose vaccination coverage, continue case-based surveillance, and monitor the patterns and rates of vaccine exemption.

Abstract
In addition to host genetic and environmental factors, variations in immune responses to vaccination are influenced by demographic variables, such as race and sex. The influence of genetic race and sex on measles vaccine responses is not well understood, yet important for the development of much-needed improved measles vaccines with lower failure rates. We assessed associations between genetically defined race and sex with measles humoral and cellular immunity after measles vaccination in three independent and geographically distinct cohorts totaling 2872 healthy racially diverse children, older adolescents, and young adults. We found no associations between biological sex and either humoral or cellular immunity to measles vaccine, and no correlation between humoral and cellular immunity in these study subjects. Genetically defined race was, however, significantly associated with both measles vaccine-induced humoral and cellular immune responses, with subjects genetically classified as having African-American ancestry demonstrating significantly higher antibody and cell-mediated immune responses relative to subjects of Caucasian ancestry. This information may be useful in designing novel measles vaccines that are optimally effective across human genetic backgrounds.
