RESUMEN

INTRODUCTION: During the coronavirus disease of 2019 (COVID-19) pandemic, routine childhood immunization rates dropped dramatically across the world, and the Military Health System (MHS) was no exception. In the MHS, which is a large, universally covered, low-to-no-cost health system, the immunization rates with the measles, mumps, and rubella (MMR) vaccine remain below the rate necessary to prevent community transmission of measles. We aimed to improve childhood immunization rates in the MHS with an expansive quality improvement project. MATERIALS AND METHODS: Measles, mumps, and rubella immunization rates served as proxy outcome measures for routine immunization rates tracked by the Center for Disease Control multi-immunization combination measures. The tracked measure was the percentage of 16- to 18-month olds and 6-year olds who had received MMR #1 and MMR #2, respectively. Various countermeasures were implemented throughout the study period, and standard quality improvement analyses informed the effect of countermeasures. RESULTS: By January 2023, the percentage of 16- to 18-month olds and 6-year olds who had received MMR #1 and MMR #2 was 85% and 91%, respectively, with no positive shift in immunization rates despite various countermeasures introduced during the study period. For reference, the MMR immunization rates of commercial health maintenance organization and commercial preferred provider organization for 24-month-old populations were 92% and 90.3%, respectively. On chart review, the most common cause for under-immunization (55%) was vaccine abandonment. MMR #1 rates rose to 92% in 24-month olds. CONCLUSIONS: Measles, mumps, and rubella immunization rates within the MHS remained below commercial health system rates and below public health standards required for herd immunity despite various countermeasures throughout the COVID-19 pandemic. Immunization rates increased with age, suggesting that children within the MHS eventually catch up despite potential barriers.

RESUMEN

Encounters for infertility care are opportunities to assess and update immunization status. Individuals of reproductive age are often unaware of their need for immunization, their immunization status, and the potentially severe consequences of preventable disease on pregnancy outcome. The purpose of this American Society for Reproductive Medicine (ASRM) Practice Committee document is to summarize current recommendations regarding vaccinations for individuals of reproductive age. This document replaces the ASRM Practice Committee document titled "Vaccination guidelines for female infertility patients," last published in 2018 (Fertil Steril 2018;110:838-41).

RESUMEN

During pregnancy, physiological changes in the immune response make pregnant women more susceptible to serious infection, increasing the risk for the mother as well as the foetus, newborn and infant. All women should be correctly and fully vaccinated as they enter their reproductive years, especially against diseases such as tetanus, hepatitis B, measles, rubella and varicella. In addition to the recommended vaccines, in risk situations, inactivated vaccines could be administered to women who were not correctly vaccinated before, while attenuated vaccines are contraindicated. Despite the fact that vaccination during pregnancy is a very important preventive measure and the existing recommendations from public health authorities, scientific societies and health professionals, the vaccination coverage could clearly be improved, especially against influenza and SARS-CoV-2, so any health professional involved in the care of pregnant women should proactively recommend these vaccines. The Spanish Association of Pediatrics (AEP), through its Advisory Committee on Vaccines, and the Spanish Society of Gynaecology and Obstetrics (SEGO) recommend vaccination against the following diseases during pregnancy: against influenza and COVID-19, in any trimester of pregnancy and during the postpartum period (up to 6 months post birth) in women not vaccinated during pregnancy; against pertussis, with the Tdap vaccine, between weeks 27 and 36 of gestation (in the CAV-AEP recommendations, preferably between weeks 27 and 28); and against RSV, with RSVPreF, between weeks 24 and 36 of gestation, preferably between weeks 32 and 36.

RESUMEN

BACKGROUND: As acceptance of artificial intelligence [AI] platforms increases, more patients will consider these tools as sources of information. The ChatGPT architecture utilizes a neural network to process natural language, thus generating responses based on the context of input text. The accuracy and completeness of ChatGPT3.5 in the context of inflammatory bowel disease [IBD] remains unclear. METHODS: In this prospective study, 38 questions worded by IBD patients were inputted into ChatGPT3.5. The following topics were covered: [1] Crohn's disease [CD], ulcerative colitis [UC], and malignancy; [2] maternal medicine; [3] infection and vaccination; and [4] complementary medicine. Responses given by ChatGPT were assessed for accuracy [1-completely incorrect to 5-completely correct] and completeness [3-point Likert scale; range 1-incomplete to 3-complete] by 14 expert gastroenterologists, in comparison with relevant ECCO guidelines. RESULTS: In terms of accuracy, most replies [84.2%] had a median score of ≥4 (interquartile range [IQR]: 2) and a mean score of 3.87 [SD: ±0.6]. For completeness, 34.2% of the replies had a median score of 3 and 55.3% had a median score of between 2 and <3. Overall, the mean rating was 2.24 [SD: ±0.4, median: 2, IQR: 1]. Though groups 3 and 4 had a higher mean for both accuracy and completeness, there was no significant scoring variation between the four question groups [Kruskal-Wallis test p > 0.05]. However, statistical analysis for the different individual questions revealed a significant difference for both accuracy [p < 0.001] and completeness [p < 0.001]. The questions which rated the highest for both accuracy and completeness were related to smoking, while the lowest rating was related to screening for malignancy and vaccinations especially in the context of immunosuppression and family planning. CONCLUSION: This is the first study to demonstrate the capability of an AI-based system to provide accurate and comprehensive answers to real-world patient queries in IBD. AI systems may serve as a useful adjunct for patients, in addition to standard of care in clinics and validated patient information resources. However, responses in specialist areas may deviate from evidence-based guidance and the replies need to give more firm advice.

RESUMEN

INTRODUCTION: This study examined the effectiveness of mobile phone reminders in improving the completeness and timeliness of childhood immunization. METHOD: We conducted a parallel arm cluster randomized controlled trial in four primary health care facilities in Nigeria. Reminders were sent to eligible participants in the intervention group at specific intervals when their children were scheduled to receive the vaccines administered at the sixth, 10, and 14 weeks after birth. Immunization records of all participants' children were then tracked to assess their immunization status. RESULTS: The immunization status of the intervention (n = 275) and control (n = 261) arms was analyzed. Completeness and timeliness of the vaccine series were significantly higher (p < .001) among children of participants in the intervention (n = 169, 61.5% and n = 138, 50.2%) than those in the control group (n = 35, 13.4% and n = 13, 5%) arm. DISCUSSION: Mobile phone reminders were established to be effective in increasing the completeness and timeliness of childhood immunization.

RESUMEN

INTRODUCTION: Vaccinations are an essential aspect of preventive medicine. In October 2021, the pneumococcal conjugate vaccine-20 (PCV-20) and PCV-15 were authorized for use in adults by the U.S. FDA. In 2022, the Advisory Committee on Immunization Practices (ACIP) subsequently published updated pneumococcal vaccination recommendations that incorporate both PCV-20 and PCV-15. Pneumococcal vaccination is effective in reducing pneumococcal disease, particularly in high-risk patient groups such as those with chronic lung disease; however, the updated dosing schedule for pneumococcal vaccinations can be quite confusing, especially if patients have previously received "older" vaccinations, such as pneumococcal polysaccharide vaccine-23 or PCV-13. The purpose of this quality improvement project was to increase providers' knowledge of current ACIP pneumococcal vaccination recommendations, including indications and dosing schedule, and to improve pneumococcal vaccination rates among eligible adults and children. MATERIALS AND METHODS: Focused education sessions were presented to primary care and subspecialty residents, fellows, and staff at Brooke Army Medical Center and Wilford Hall Ambulatory Surgical Center regarding current ACIP pneumococcal vaccination recommendations. Sessions included information about PCV-15 and PCV-20 vaccines, indications for vaccination, and dosing schedules. Subjective knowledge of updated ACIP pneumococcal vaccination recommendations was assessed among primary care and subspecialty residents, fellows, and staff via an anonymous survey both pre- and post-intervention. Number of PCV-20 vaccinations given and estimated vaccination rates of patients aged 19 to 64 years with asthma were assessed pre- and post-intervention over a 6 month time span. RESULTS: Of surveyed providers, only 9% discussed vaccinations at every visit and 11% did not discuss vaccinations at all. There was a statistically significant increase in providers' knowledge of pneumococcal vaccination guidelines for children post-intervention (P = .01) but no statistically significant increase in knowledge for guidelines for adults, for patients that have received prior pneumococcal vaccines, or in overall confidence in recommending pneumococcal vaccines. There was a 17% increase in the number of PCV-20 vaccinations given post-intervention (198 pre-intervention, 232 post-intervention). The estimated PCV-20 vaccination rate for adults aged 19 to 64 years with asthma increased from 14.9% pre-intervention to 19.5% post-intervention (P = .33). CONCLUSIONS: There is a significant knowledge gap regarding ACIP pneumococcal vaccination recommendations among military providers and a low pneumococcal vaccination rate for adults aged 19 to 64 years with asthma at Joint Base-San Antonio MTFs. Focused education sessions were effective in increasing providers' knowledge of updated pneumococcal vaccination recommendations, confidence in recommending vaccines, total number of pneumococcal vaccinations given, and estimated pneumococcal vaccination rate for adults with asthma. The validity of conclusions drawn from our data were limited because of discordant numbers of survey respondents as well as potentially inaccurate estimates of pneumococcal vaccination rates pre- and post-intervention. Despite this, the results warrant continued education of pneumococcal vaccines, indications, and dosing schedules.

RESUMEN

PURPOSE: To guide the vaccination of adults with solid tumors or hematologic malignancies. METHODS: A systematic literature review identified systematic reviews, randomized controlled trials (RCTs), and nonrandomized studies on the efficacy and safety of vaccines used by adults with cancer or their household contacts. This review builds on a 2013 guideline by the Infectious Disease Society of America. PubMed and the Cochrane Library were searched from January 1, 2013, to February 16, 2023. ASCO convened an Expert Panel to review the evidence and formulate recommendations. RESULTS: A total of 102 publications were included in the systematic review: 24 systematic reviews, 14 RCTs, and 64 nonrandomized studies. The largest body of evidence addressed COVID-19 vaccines. RECOMMENDATIONS: The goal of vaccination is to limit the severity of infection and prevent infection where feasible. Optimizing vaccination status should be considered a key element in the care of patients with cancer. This approach includes the documentation of vaccination status at the time of the first patient visit; timely provision of recommended vaccines; and appropriate revaccination after hematopoietic stem-cell transplantation, chimeric antigen receptor T-cell therapy, or B-cell-depleting therapy. Active interaction and coordination among healthcare providers, including primary care practitioners, pharmacists, and nursing team members, are needed. Vaccination of household contacts will enhance protection for patients with cancer. Some vaccination and revaccination plans for patients with cancer may be affected by the underlying immune status and the anticancer therapy received. As a result, vaccine strategies may differ from the vaccine recommendations for the general healthy adult population vaccine.Additional information is available at www.asco.org/supportive-care-guidelines.

RESUMEN

BACKGROUND: For psoriatic patients who need to receive nonlive or live vaccines, evidence-based recommendations are needed regarding whether to pause or continue systemic therapies for psoriasis and/or psoriatic arthritis. OBJECTIVE: To evaluate literature regarding vaccine efficacy and safety and to generate consensus-based recommendations for adults receiving systemic therapies for psoriasis and/or psoriatic arthritis receiving nonlive or live vaccines. METHODS: Using a modified Delphi process, 22 consensus statements were developed by the National Psoriasis Foundation Medical Board and COVID-19 Task Force, and infectious disease experts. RESULTS: Key recommendations include continuing most oral and biologic therapies without modification for patients receiving nonlive vaccines; consider interruption of methotrexate for nonlive vaccines. For patients receiving live vaccines, discontinue most oral and biologic medications before and after administration of live vaccine. Specific recommendations include discontinuing most biologic therapies, except for abatacept, for 2-3 half-lives before live vaccine administration and deferring next dose 2-4 weeks after live vaccination. LIMITATIONS: Studies regarding infection rates after vaccination are lacking. CONCLUSION: Interruption of antipsoriatic oral and biologic therapies is generally not necessary for patients receiving nonlive vaccines. Temporary interruption of oral and biologic therapies before and after administration of live vaccines is recommended in most cases.

RESUMEN

The number of people with immunosuppression is increasing considerably due to their greater survival and the use of new immunosuppressive treatments for various chronic diseases. This is a heterogeneous group of patients in whom vaccination as a preventive measure is one of the basic pillars of their wellbeing, given their increased risk of contracting infections. This consensus, developed jointly by the Sociedad Española de Infectología Pediátrica (Spanish Society of Pediatric Infectious Diseases) and the Advisory Committee on Vaccines of the Asociación Española de Pediatría (Spanish Association of Paediatrics), provides guidelines for the development of a personalised vaccination schedule for patients in special situations, including general recommendations and specific recommendations for vaccination of bone marrow and solid organ transplant recipients, children with inborn errors of immunity, oncologic patients, patients with chronic or systemic diseases and immunosuppressed travellers.

RESUMEN

OBJECTIVE: To evaluate the effect of a health maintenance reminder (HMR) on human papillomavirus (HPV) vaccine administration and completion across different age, insurance, and race cohorts. STUDY DESIGN: Retrospective pre-post analysis. SETTING: Academic primary care. METHODS: Patients aged 9 to 26 who had initiated the HPV vaccine series from 2016 to 2021 were analyzed, based on current age-based standards. The cohort was divided based on vaccine uptake before and after the implementation of the HMR program in February 2020. The multivariate analysis estimated the odds of vaccine completion based on sociodemographic factors, and variable interactions were investigated to determine independent associations between sociodemographic factors and HMR implementation. RESULTS: There were 7654 individual patients (mean age was 15.8 years; 46.7 were males; and 50.7% were white). HPV vaccine completion rates increased post-HMR implementation by 59.2% (37% pre-, and 58.9% post-HMR; p < .001) in the entire cohort. Overall, black patients (adjusted odds ratio [aOR] = 0.68; 95% confidence interval [CI]: 0.60, 0.70) and patients ≥18 years (aOR = 0.13; 95% CI: 0.11, 0.15) were significantly less likely to complete their vaccine series; however, this improved significantly following HMR in these groups (p < .001). Post-HMR, race, and insurance status were not independently associated with disparate vaccine completion rates, however, age was, and patients ≤14 or younger had higher odds of vaccine completion (aOR = 3.54; 95% CI: 2.91, 4.32). CONCLUSION: The implementation of an HMR was associated with increased HPV vaccine uptake across age and race groups in this single-institution study. Future research should explore barriers to implementing HMRs in different health care settings.

RESUMEN

Importance: Given limited COVID-19 vaccine availability early in the pandemic, optimizing immunization strategies was of paramount importance. Ring vaccination has been used successfully to control transmission of other airborne respiratory viruses. Objective: To assess the association of a ring vaccination intervention on COVID-19 spread in the initial epicenter of SARS-CoV-2 Alpha variant transmission in Montreal, Canada. Design, Setting, and Participants: This cohort study compared COVID-19 daily disease risk in 3 population-based groups of neighborhoods in Montreal, Canada, defined by their intervention-specific vaccine coverage at the neighborhood level: the primary intervention group (500 or more vaccinated persons per 10 000 persons), secondary intervention group (95 to 499), and control group (0 to 50). The groups were compared within each of 3 time periods: before intervention (December 1, 2020, to March 16, 2021), during and immediately after intervention (March 17 to April 17, 2021), and 3 weeks after the intervention midpoint (April 18 to July 18, 2021). Data were analyzed between June 2021 and November 2021. Exposures: Vaccination targeted parents and teachers of children attending the 32 schools and 48 childcare centers in 2 adjacent neighborhoods with highest local transmission (case counts) of Alpha variant shortly after its introduction. Participants were invited to receive 1 dose of mRNA vaccine between March 22 and April 9, 2021 (before vaccine was available to these age groups). Main Outcomes and Measures: COVID-19 risk in 3 groups of neighborhoods based on intervention-specific vaccine coverage. Results: A total of 11 794 residents were immunized, with a mean (SD) age of 43 (8) years (range, 16-93 years); 5766 participants (48.9%) lived in a targeted neighborhood, and 9784 (83.0%) were parents. COVID-19 risk in the primary intervention group was significantly higher than in the control group before (unadjusted risk ratio [RR], 1.58; 95% CI 1.52-1.65) and during (RR, 1.63; 95% CI, 1.52-1.76) intervention, and reached a level similar to the other groups in the weeks following the intervention (RR, 1.03; 95% CI, 0.94-1.12). A similar trend was observed when restricting to SARS-CoV-2 variants and persons aged 30 to 59 years (before: RR, 1.72; 95% CI, 1.63-1.83 vs after: RR, 1.01; 95% CI, 0.88-1.17). Conclusions and Relevance: Our findings show that ring vaccination was associated with a reduction in COVID-19 risk in areas with high local transmission of Alpha variant shortly after its introduction. Ring vaccination may be considered as an adjunct to mass immunization to control transmission in specific areas, based on local epidemiology.

RESUMEN

Various commercial anti-Spike SARS-CoV-2 antibody tests are used for studies and in clinical settings after vaccination. An international standard for SARS-CoV-2 antibodies has been established to achieve comparability of such tests, allowing conversions to BAU/mL. This study aimed to investigate the comparability of antibody tests regarding the timing of blood collection after vaccination. For this prospective observational study, antibody levels of 50 participants with homologous AZD1222 vaccination were evaluated at 3 and 11 weeks after the first dose and 3 weeks after the second dose using two commercial anti-Spike binding antibody assays (Roche and Abbott) and a surrogate neutralization assay. The correlation between Roche and Abbott changed significantly depending on the time point studied. Although Abbott provided values three times higher than Roche 3 weeks after the first dose, the values for Roche were twice as high as for Abbott 11 weeks after the first dose and 5 to 6 times higher at 3 weeks after the second dose. The comparability of quantitative anti-Spike SARS-CoV-2 antibody tests was highly dependent on the timing of blood collection after vaccination. Therefore, standardization of the timing of blood collection might be necessary for the comparability of different quantitative SARS-COV-2 antibody assays. IMPORTANCE This work showed that the comparability of apparently standardized SARS-CoV-2 antibody assays (Roche, Abbott; both given in BAU/mL) after vaccination depends on the time of blood withdrawal. Initially (3 weeks after the first dose AZD1222), there were 3 times higher values in the Abbott assay, but this relationship inversed before boosting (11 weeks after the first dose) with Roche 2 times greater than Abbott. After the booster, Roche quantified ca. 5 times higher levels than Abbott. This must be considered by clinicians when interpreting SARS-CoV-2 antibody levels.
