Objectives: This study assesses the effectiveness of nirsevimab, a monoclonal antibody, in preventing medically attended respiratory syncytial virus-lower respiratory tract infections (RSV-LRTI) in a large primary care network in Spain, in both overall and catch-up infants under ten months of age., Methods: The 2023-24 immunization campaign with nirsevimab in Spain targeted all infants born after April 1st, 2023. Those born after October 1st received it at birth in hospitals, while others received it through a catch-up program. The MEDIPRIM network of primary care centers recruited all infants with LRTI for RSV PCR testing and employed a test-negative design (TND) approach to estimate the effectiveness of nirsevimab., Results: The study included 160 infants, 141 (88%) of them received nirsevimab and 128 belonged to the catch-up group (88% received nirsevimab). Overall, RSV was detected in 44 infants (27.5%). Within the catch-up group, 37 (28.9%) were positive for RSV. The overall effectiveness was 75.8% (95% CI: 40.4-92.7), and 80.2% (95% CI: 44.3-95.4) in infants belonging to the catch-up group., Conclusions: This study underscores the effectiveness of nirsevimab in preventing medically attended LRTI in infants in outpatient settings and emphasizes the importance of a catch-up immunization program to reduce the disease burden in primary care., Competing Interests: CONFLICT OF INTEREST DISCLOSURES: Cintia Muñoz-Quiles, Mónica López-Lacort, Javier Díez-Domingo, and Alejandro Orrico-Sánchez have attended several congresses, whose registration, travel, and accommodation costs covered by MSD, GSK, AZ, and SP.

Purpose: To evaluate the influence of viewing the Olfatín Project video on the assessment of school LAIV-associated pain in three and four-year-old children through the Wong Baker Faces® pain classification scale., Design and Methods: A three-arm randomized multicenter clinical trial with a placebo control group was carried out. The main variable measured was pain, assessed through the score on the Wong Baker Faces® Pain Rating Scale. There were a total population of 4591 children three and four-year-olds (born in 2019 and 2020) and who attended the 1st and 2nd year of early childhood education. Before the school vaccination, researchers randomly assigned participant schools corresponding to each of the basic health areas to each of the three study groups: Olfatín's video viewing, a control video viewing not related to influenza and no video viewing., Results: No significant differences according to sex, age or the minor's grade according to the assigned intervention were detected. 72.3% of those vaccinated assigned a 0 from the Wong Baker Faces® scale: 75.4% of those who watched Olfatín's video, 68.3% for those in Drilo's group and 72.8% for those who didn't watch any video, but without significant differences (p = 0.08). There were no significant differences either stratifying by sex., Conclusion: LAIV is a painless vaccine for children, which has to be taken into account by the health authorities when planning the pediatric influenza vaccination campaign., Practice Implications: Olfatín's cartoon video can be used by professionals to create a greater experience for children and therefore a better acceptance., Competing Interests: Declaration of competing interest J.J.P.M. and M.Z.M. have collaborated in teaching activities subsidized by AstraZeneca, having also received financial aid to attend national and international teaching activities.

Respiratory syncytial virus (RSV) is the main cause of low respiratory tract infections in infants under one year of age. In the 2023/2024 season, the monoclonal antibody nirsevimab was available to protect children from RSV, and Spain has become one of the first countries worldwide to implement this strategy. It is essential to evaluate the results of this first campaign and different characteristics of the immunized population in order to plan next campaigns, especially for countries that are going to include this immunization. Our coverage was high (91.5% for those born during the season and 88.3% globally). For those born during the season, only 4.9% preferred not to immunize at the maternity hospital, which meant an average delay of 27.45 days. We observed a lower coverage in the population of immigrant origin. There was a rapid pace of immunization, since for those born before the beginning of the campaign the mean to be immunized was 15.63 days, without differences between healthy and at-risk children. This allows immunization before the RSV season (90% of the catch-up children had been immunized on November 3). The average age at which all the immunized children have received nirsevimab was lower in healthy children compared to those with risk conditions (49.65 versus 232.85 days). For those born during the campaign, the average age was also lower in healthy children (3.14 versus 14.58 days). In conclusion, we consider that the implementation of the immunization strategy with nirsevimab in the Region of Murcia, Spain, has been a success.

Respiratory syncytial virus (RSV) is the leading cause of lower respiratory tract infections in young children and associated with most bronchiolitis- and pneumonia-related hospitalizations. A new preventive monoclonal antibody (MAb), nirsevimab, has been launched in the United States, Luxembourg, and France, and was recently approved to be given in a population-based manner throughout Spain. This study aimed to have a first pre-immunization insight into the Spanish parental knowledge about bronchiolitis, RSV, and nirsevimab immunization. Parents in Murcia with children <2 years of age up to the date of September 1, 2023, were selected to complete a questionnaire. The primary endpoint was the parental knowledge about bronchiolitis, RSV, and nirsevimab. A total of 3,217 responses were analyzed. The majority (95.8%) were aware of bronchiolitis. Meanwhile, 46.6% of the respondents knew about RSV, most of them only after the first child's birth. Information about RSV or bronchiolitis was mainly obtained from family members, with only 4.8% reporting having been informed by Health care Professionals (HCPs). Only 11.2% of respondents were aware of nirsevimab. Nonetheless, these were not entirely satisfied with the information received (score of 3.3 out of 5) and shared that HCPs should be the primary source of information. The present survey then highlights the need for better and more efficient educational strategies directed to all parents/legal guardians. It also sheds some light on the different factors that should be considered to improve awareness of RSV immunization to decrease its burden in Spain and beyond.

Background: During the 2022-23 season, three autonomous communities recommended influenza vaccination for all children between 6 and 59 months. The objective is to evaluate the adverse effects associated with the administered influenza vaccines in the Region of Murcia, as well as their influence on the recommendation of the same to acquaintances or repetition in future seasons., Material and Methods: Cross-sectional descriptive study with an online questionnaire sent to the parents of vaccinated minors of 6-23 months of age receiving inactivated intramuscular vaccine (IIV) or 24-59 months of age receiving live-attenuated intranasal vaccine (LAIV)., Results: Among 4971 surveys received, the most common adverse effect for LAIV and IIV was runny nose (40.90%) and local pain (31.94%), respectively. Sixty percent of adverse effects lasted ≤ 1 day, and around 10% lasted ≥ 3 days. The interference of adverse effects with the minor's daily life was very infrequent (3.32%), as was the need for visiting the medical office (2.68%). Overall, 96.44% of parents would recommend influenza vaccination to friends and relatives after the experience. Only 3.56% would not recommend it, while 1.68% would not vaccinate their child against influenza again. The most frequently cited reason being adverse effects., Conclusions: Our study shows the safety of influenza vaccines. Despite the low impact of adverse effects, they influence some parents in their intention to continue vaccinating or recommending it to acquaintances, which remarks the need to reinforce the information given to parents so that this fact does not influence decision-making., (© 2024 The Author(s).

In the 2022-2023 influenza season, three autonomous communities anticipated the document approved by the Public Health Commission recommending influenza vaccination for all children aged 6 to 59 months. The primary objective of this study was to evaluate the attitude of healthcare professionals towards the first universal vaccination campaign in our region, as well as the acceptability of the vaccines used and their attitude towards pilot school vaccination. This was a cross-sectional, survey-based, descriptive study. All healthcare professionals involved in the campaign were invited to participate. Overall, 91.9% of surveyed professionals thought that influenza vaccination from 6 to 59 months was important or very important, and 89.8% had previous experience regarding the intramuscular vaccine. Healthcare professionals rated the intranasal vaccine significantly more positively, but there were no differences when asking about each vaccine without comparison. The inhaled vaccine was preferred by 97.5% for the following campaign. Pilot school vaccination had a 75% acceptance rate. The inhaled vaccine was preferred by most professionals, and pilot school vaccination was highly accepted and independently associated with the importance of vaccination as considered by physicians, being a medical doctor, and participation in the pilot programme.

Background: With more than 7500 cases reported since April 2022, Spain has experienced the highest incidence of mpox in Europe. From 12 July onward, the modified vaccinia Ankara-Bavaria Nordic (MVA-BN) smallpox vaccine was offered as pre-exposure prophylaxis for those receiving pre-exposure prophylaxis for human immunodeficiency virus (HIV-PrEP). Our aim was to assess the effectiveness of 1 dose of MVA-BN vaccine as pre-exposure prophylaxis against mpox virus (MPXV) infection in persons on HIV-PrEP., Methods: National retrospective cohort study between 12 July and 12 December 2022. Individuals aged ≥18 years receiving HIV-PrEP as of 12 July with no previous MPXV infection or vaccination were eligible. Each day, we matched individuals receiving a first dose of vaccine and unvaccinated controls of the same age and region. We used a Kaplan-Meier estimator, calculated risk ratios (RR) and vaccine effectiveness (VE = [1 - RR]x100)., Results: We included 5660 matched pairs, with a median follow-up of 62 days (interquartile range, 24-97). Mpox cumulative incidence was 5.6 per 1000 (25 cases) in unvaccinated and 3.5 per 1000 (18 cases) in vaccinated. No effect was found during days 0-6 post-vaccination (VE, -38.3; 95% confidence interval [CI], -332.7 to 46.4), but VE was 65% at ≥7 days (95% CI, 22.9 to 88.0) and 79% at ≥14 days (95% CI, 33.3 to 100.0) post-vaccination., Conclusions: One dose of MVA-BN vaccine offered protection against mpox in most-at-risk population shortly after the vaccination. Further studies need to assess the VE of a second dose and the duration of protection over time., Competing Interests: Potential conflicts of interest. A. G. T. reports financial support for expert testimony from Moderna and GSK and for attending meetings and/or travel from Pfizer and MSD. All other authors report no potential conflicts.

The high burden of influenza in children has driven numerous countries towards universal vaccination of healthy children from 6 to 59 months of age. The Region of Murcia was one of the pioneer Spanish regions to conduct a universal vaccination campaign and to use live-attenuated intranasal vaccine (LAIV) if age appropriate. This study aims to evaluate the parents' likeliness to vaccinate their children and to compare the profile of vaccinating/non-vaccinating parents. This study was designed as a prospective, real-world, survey-based data collection in the 2022-2023 season campaign. This study's sample was selected from those children whose information was available in the local Public Health System databases PERSAN and VACUSAN. Children received LAIV or intramuscular vaccine (IIV) depending on their age as per standard practice. The parent self-vaccination/intention to vaccinate themselves in this campaign (OR = 4.75), the compliance with the official vaccination schedule (OR = 3.41), and the prescription of antibiotics more than twice in the previous year (OR = 2.24) were strongly associated with children's vaccination. Overall, vaccinating parents were very satisfied with the vaccine (IIV: 67.5% vs. LAIV: 68.8%, p = 0.320), and most parents would rather have their children vaccinated with LAIV for the next campaign (43.0%). The main reasons for vaccinating were to protect the child (LAIV: 85.9% vs. IIV: 89.4%), and the predominant reasons for not vaccinating were a lack of healthcare professional recommendation (30.9%), and lack of information about the vaccination campaign (21.5%) and the vaccine itself (21.0%). The clinical context of parents and children was determinant in decision making, which was also influenced by the presence or absence of recommendation by healthcare professionals. Parents were generally very satisfied with the vaccine and showed their preference towards LAIV for future campaigns.

The monoclonal antibody nirsevimab was at least 70% effective in preventing hospitalisations in infants with lower respiratory tract infections (LRTI) positive for respiratory syncytial virus (RSV) in Spain (Oct 2023-Jan 2024), where a universal immunisation programme began late September (coverage range: 79-99%). High protection was confirmed by two methodological designs (screening and test-negative) in a multicentre active surveillance in nine hospitals in three regions. No protection against RSV-negative LRTI-hospitalisations was shown. These interim results could guide public-health decision-making.

The influenza virus has accompanied humans since time immemorial, in the form of annual epidemics and occasional pandemics. It is a respiratory infection with multiple repercussions on people's lives at an individual and social level, as well as representing a significant burden on the health system. This Consensus Document arises from the collaboration of various Spanish scientific societies involved in influenza virus infection. The conclusions drawn are based on the highest quality evidence available in the scientific literature and, failing that, on the opinion of the experts convened. The Consensus Document addresses the clinical, microbiological, therapeutic, and preventive aspects (with respect to the prevention of transmission and in relation to vaccination) of influenza, for both adult and pediatric populations. This Consensus Document aims to help facilitate the clinical, microbiological, and preventive approach to influenza virus infection and, consequently, to reduce its important consequences on the morbidity and mortality of the population., (Copyright © 2023 The Authors.

The most effective means of preventing seasonal influenza is through strain-specific vaccination. In this study, we investigated the efficacy, effectiveness and safety of cell-based trivalent and quadrivalent influenza vaccines. A systematic literature search was conducted in electronic databases and grey literature sources up to 7 February 2020. Randomised controlled trials (RCTs) and non-randomised studies of interventions (NRSIs) were eligible for inclusion. Two reviewers independently screened, extracted data and assessed the risk of bias of included studies. Certainty of evidence for key outcomes was assessed using the GRADE methodology. The search returned 28,846 records, of which 868 full-text articles were assessed for relevance. Of these, 19 studies met the inclusion criteria. No relative efficacy data were identified for the direct comparison of cell-based vaccines compared with traditional vaccines (egg-based). Efficacy data were available comparing cell-based trivalent influenza vaccines with placebo in adults (aged 18-49 years). Overall vaccine efficacy was 70% against any influenza subtype (95% CI 61%-77%, two RCTS), 82% against influenza A(H1N1) (95% CI 71%-89%, 2 RCTs), 72% against influenza A(H3N2) (95% CI 39%-87%, 2 RCTs) and 52% against influenza B (95% CI 30%-68%, 2 RCTs). Limited and heterogeneous data were presented for effectiveness when compared with no vaccination. One NRSI compared cell-based trivalent and quadrivalent vaccination with traditional trivalent and quadrivalent vaccination, finding a small but significant difference in favour of cell-based vaccines for influenza-related hospitalisation, hospital encounters and physician office visits. The safety profile of cell-based trivalent vaccines was comparable to traditional trivalent influenza vaccines. Compared with placebo, cell-based trivalent influenza vaccines have demonstrated greater efficacy in adults aged 18-49 years. Overall cell-based vaccines are well-tolerated in adults, however, evidence regarding the effectiveness of these vaccines compared with traditional seasonal influenza vaccines is limited., (© 2022 John Wiley & Sons Ltd.)

This review sought to assess the efficacy, effectiveness and safety of high-dose inactivated influenza vaccines (HD-IIV) for the prevention of laboratory-confirmed influenza in individuals aged 18 years or older. A systematic literature search was conducted in electronic databases and grey literature sources up to 7 February 2020. Randomised controlled trials (RCTs) and non-randomised studies of interventions (NRSIs) were included. The search returned 28,846 records, of which 36 studies were included. HD-IIV was shown to have higher relative vaccine efficacy in preventing influenza compared with standard-dose influenza vaccines (SD-IIV3) in older adults (Vaccine effectiveness (VE) = 24%, 95% CI 10-37, one RCT). One NRSI demonstrated significant effect for HD-IIV3 against influenza B (VE = 89%, 95% CI 47-100), but not for influenza A(H3N2) (VE = 22%, 95% CI -82 to 66) when compared with no vaccination in older adults. HD-IIV3 showed significant relative effect compared with SD-IIV3 for influenza-related hospitalisation (VE = 11.8%, 95% CI 6.4-17.0, two NRSIs), influenza- or pneumonia-related hospitalisation (VE = 13.7%, 95% CI 9.5-17.7, three NRSIs), influenza-related hospital encounters (VE = 13.1%, 95% CI 8.4-17.7, five NRSIs), and influenza-related office visits (VE = 3.5%, 95% CI 1.5-5.5, two NRSIs). For safety, HD-IIV were associated with significantly higher rates of local and systemic adverse events compared with SD-IIV (combined local reactions, pain at injection site, swelling, induration, headache, chills and malaise). From limited data, compared with SD-IIV, HD-IIV were found to be more effective in the prevention of laboratory-confirmed influenza, for a range of proxy outcome measures, and associated with more adverse events., (© 2022 John Wiley & Sons Ltd.)

Despite the impact of the COVID-19 vaccination, vaccine hesitancy is a matter of concern. Despite a lower disease incidence, people continue to start primo-vaccination late. The aim of this study is to characterize people late primo-vaccinated and the reasons that led them to start vaccination. A quantitative, descriptive and prospective study was performed on the basis of phone surveys of people vaccinated from February to May 2022 in the Region of Murcia (Spain). The survey included socio-demographic and COVID-19 information, self-perception risk, vaccine security, Fear of COVID-19 Scale, reasons for not being vaccinated and reasons that have led them to vaccination. From a total of 1768 people receiving primo-vaccination, 798 people were contacted, and 338 people completed the survey. Among the interviewed people, 57% reported non-health-related reasons to get vaccinated, travel reasons being the primary one. The most reported health-related reason was a fear of COVID-19. There was a significant positive association between vaccination for health-related reasons and female gender (β = 0.72), cohabiting with a vulnerable person (β = 0.97), higher self-perceived risk (β = 0.13) and vaccine security dimension (β = 0.14). We identified two different profiles of people with late COVID-19 primo-vaccination, with health-related or non-health-related reasons. This work can be useful in designing specific communication strategies.

Introduction: The state of alarm was declared in Spain due to the COVID-19 epidemic on March 14, 2020, and established population confinement measures. The objective is to describe the process of lifting these mitigation measures., Methods: The Plan for the Transition to a New Normality, approved on April 28, contained four sequential phases with progressive increase in socio-economic activities and population mobility. In parallel, a new strategy for early diagnosis, surveillance and control was implemented. A bilateral decision mechanism was established between the Spanish Government and the autonomous communities (AC), guided by a set of qualitative and quantitative indicators capturing the epidemiological situation and core capacities. The territorial units were established ad-hoc and could be from Basic Health Zones to entire AC., Results: The process run from May 4 to June 21, 2020. AC implemented plans for reinforcement of core capacities. Incidence decreased from a median (50% of territories) of 7.4 per 100,000 in 7 days at the beginning to 2.5 at the end. Median PCR testing increased from 53% to 89% of suspected cases and PCR total capacity from 4.5 to 9.8 per 1000 inhabitants weekly; positivity rate decreased from 3.5% to 1.8%. Median proportion of cases with traced contacts increased from 82% to 100%., Conclusion: Systematic data collection, analysis, and interterritorial dialogue allowed adequate process control. The epidemiological situation improved but, mostly, the process entailed a great reinforcement of core response capacities nation-wide, under common criteria. Maintaining and further reinforcing capacities remained crucial for responding to future waves., (Copyright © 2021 Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

The 2019 coronavirus disease pandemic can have an alarming impact on vaccination coverage. WHO, UNICEF and Gavi warn that at least 80 million children under the age of 1 are at risk of contracting diseases such as diphtheria, measles and polio due to the interruption of routine immunization and the temporary suspension of 93 campaigns of large-scale vaccination.In Spain, a new healthcare scenario, which prioritizes telematics over in person, fear of contagion by going to health centers, and recommendations for physical distance and restricted mobility, reduce attendance at primary care centers. Despite recommendations established by the health authorities, vaccination coverage has decreased in all Autonomous Communities between 5% and 60%, depending on the age and type of vaccine. School vaccinations have been suspended and only vaccination of pregnant women against tetanus, diphtheria and pertussis has been maintained. The decrease has been more evident for non gratuity vaccines: the first dose of meningococcal vaccine B has decreased by 68.4% in the Valencian Community, and Andalusia has observed a 39% decrease in the total doses of this vaccine and of 18% for that of rotavirus.The recovering of vaccinations should be planned, organized and carried out in the shortest possible time.This article discusses some aspects of the recovery of vaccination coverage for different groups: children, adolescents and adults, and patients at risk and in special situations., (© 2020 Published by Elsevier España, S.L.U.)

Objective: Splenectomy patients have a high risk of suffering severe infections, many of them preventable by vaccination. The aim of the study was to analyse the clinical epidemiological characteristics and vaccine coverage of these patients in Health Area III of the Region of Murcia., Method: A cross-sectional study was conducted on a population of patients that were splenectomised during the period 1993-2012, according to the Register of the Basic Minimum Data Set. Patients were classified on the basis of splenectomy (neoplasm, haematological diseases, trauma, and others), vaccination, and vital status, using official records of health data. Statistical analysis was performed using SPSS 21.0 statistics program., Results: The sample consisted of 196 patients, of which 68.4% (n=134) were male. The mean age at which they underwent splenectomy was 50.1 years (SD: 22.2). The most common reason for removal of the spleen was neoplasia in 39.1% (n=59). Splenectomy due to trauma reasons was associated with lower patient age (p<.001) and male gender (p=.03). Vaccination coverage for Streptococcus pneumoniae was 23.8%, 5.7% for Neisseria meningitidis C, and 8.6% for Haemophilus influenzae B. Only 2.9% of patients were correctly vaccinated for all three., Conclusions: Vaccination coverage was insufficient for this fragile patient profile. It should be taken into account in the early detection and counselling in this group so susceptible to disease, with nurses being a decisive part in the process., (Copyright © 2017 Elsevier España, S.L.U.

Outbreaks in temporary camps are an important risk for the health of the displaced population. The town of Lorca (Murcia, Spain) suffered 2 earthquakes on May 2011 that required the re-housing of 1,424 victims in a temporary camp. Following 4 cases of chickenpox control measures were adopted among the displaced population. These measures included vaccination against chickenpox; due to the existence of cases of measles in adjacent regions, it was decided to offer measles, mumps and rubella (MMR) vaccination as well. The immunization campaign was performed during 2 d (3 to 4 d after the first case). The immunity status of 1,041 (73,1%) of the residents was reviewed. Being vaccinated 523 (67%) against chickenpox and MMR, 133 (17%) against only MMR and 124 (16%) against only chickenpox. We consider the action taken was a success, as only 4 additional cases of chickenpox were subsequently recorded in the campsite, being avoidable only one of them. There is a major risk of outbreaks in a disaster situation. Because of this, conducting preventive actions are indicated to avoid doing worse this critical.

Objective: To estimate the effectiveness of the varicella vaccine in school outbreaks during the academic year 2009-2010., Material and Method: Retrospective cohort study in public day-care centers and/or schools in an area in the region of Murcia. Spain. The participants were all children of 1 to 12 years who were in the same classroom where there was an outbreak of varicella. The main measurements were the sociodemographic, clinical and vaccination data, as well as variables related to varicella disease obtained through a questionnaire self-completed by parents, and from the computerized regional immunization registry (VACUSAN)., Results: A total of 51 varicella outbreaks were detected, with a median of 3 cases per outbreak at both educational levels. The overall vaccination coverage was 10.7% (95% CI 8.63 to 13.18), always being higher in Spanish schoolchildren versus foreign (OR: 21.21, 95% CI: 2.92 to 153.92, P<.001).
