RESUMO
BACKGROUND: Yearly influenza vaccination is strongly recommended for older adults and patients with chronic diseases including cardiovascular disease (CVD); however, vaccination rates remain suboptimal, particularly among younger patients. Electronic letters incorporating behavioral nudges are highly scalable public health interventions which can potentially increase vaccination, but further research is needed to determine the most effective strategies and to assess effectiveness across different populations. The purpose of NUDGE-FLU-CHRONIC and NUDGE-FLU-2 are to evaluate the effectiveness of electronic nudges delivered via the Danish governmental electronic letter system in increasing influenza vaccination among patients with chronic diseases and older adults, respectively. METHODS: Both trials are designed as pragmatic randomized implementation trials enrolling all Danish citizens in their respective target groups and conducted during the 2023/2024 influenza season. NUDGE-FLU-CHRONIC enrolls patients aged 18-64 years with chronic diseases. NUDGE-FLU-2 builds upon the NUDGE-FLU trial conducted in 2022/2023 and aims to expand the evidence by testing both previously successful and new nudges among adults ≥65 years during a subsequent influenza season. Persons with exemptions from the electronic letter system are excluded from both trials. In both trials, participants are randomized in a 2.45:1:1:1:1:1:1 ratio to either receive no electronic letter (usual care) or to receive one of 6 different behaviorally informed electronic letters. NUDGE-FLU-CHRONIC has randomized 299,881 participants with intervention letters delivered on September 24, 2023, while NUDGE-FLU-2 has randomized 881,373 participants and delivered intervention letters on September 13, 2023. Follow-up is currently ongoing. In both trials, the primary endpoint is receipt of influenza vaccination on or before January 1, 2024, and the secondary endpoint is time to vaccination. Clinical outcomes including respiratory and cardiovascular hospitalizations, all-cause hospitalization, and mortality are included as prespecified exploratory endpoints. Prespecified individual-level pooled analyses will be conducted across NUDGE-FLU, NUDGE-FLU-CHRONIC, and NUDGE-FLU-2. DISCUSSION: NUDGE-FLU-CHRONIC is the first nationwide randomized trial of electronic nudges to increase influenza vaccination conducted among 18-64-year-old high-risk patients with chronic diseases. NUDGE-FLU-2 will provide further evidence on the effectiveness of electronic nudges among older adults ≥65 years. Collectively, the NUDGE-FLU trials will provide an extensive evidence base for future public health communications.

AIM: High-dose quadrivalent influenza vaccine (QIV-HD) has been shown to be more effective than standard-dose (QIV-SD) in reducing influenza infection, but whether diabetes status affects relative vaccine effectiveness (rVE) is unknown. We aimed to assess rVE on change in glycated haemoglobin [HbA1c (∆HbA1c)], incident diabetes, total all-cause hospitalizations (first + recurrent), and a composite of all-cause mortality and hospitalization for pneumonia or influenza. METHODS: DANFLU-1 was a pragmatic, open-label trial randomizing adults (65-79 years) 1:1 to QIV-HD or QIV-SD during the 2021/22 influenza season. Cox proportional hazards regression was used to estimate rVE against incident diabetes and the composite endpoint, negative binomial regression to estimate rVE against all-cause hospitalizations, and ANCOVA when assessing rVE against ∆HbA1c. RESULTS: Of the 12 477 participants, 1162 (9.3%) had diabetes at baseline. QIV-HD, compared with QIV-SD, was associated with a reduction in the rate of all-cause hospitalizations irrespective of diabetes [overall: 647 vs. 742 events, incidence rate ratio (IRR): 0.87, 95% CI (0.76-0.99); diabetes: 93 vs. 118 events, IRR: 0.80, 95% CI (0.55-1.15); without diabetes: 554 vs. 624 events, IRR: 0.88, 95% CI (0.76-1.01), pinteraction = 0.62]. Among those with diabetes, QIV-HD was associated with a lower risk of the composite outcome [2 vs. 11 events, HR: 0.18, 95% CI (0.04-0.83)] but had no effect on ∆HbA1c; QIV-HD adjusted mean difference: ∆ + 0.2 mmol/mol, 95% CI (-0.9 to 1.2). QIV-HD did not affect the risk of incident diabetes [HR 1.18, 95% CI (0.94-1.47)]. CONCLUSIONS: In this post-hoc analysis, QIV-HD versus QIV-SD was associated with an increased rVE against the composite of all-cause death and hospitalization for pneumonia/influenza, and the all-cause hospitalization rate irrespective of diabetes status.

OBJECTIVE: To estimate the economic burden of non-communicable diseases (NCDs) in people living with HIV (PLWH) in Denmark. METHODS: We conducted a cohort study using population-based Danish medical registries including all adult residents of the Central Denmark Region registered with a first-time HIV-diagnosis during the period 2006-2017. For each PLWH, we matched 10 persons without HIV from the background population by birth year, sex and municipality of residence. Information on healthcare utilization and costs for the PLWH and non-HIV cohorts was retrieved from register data. For each cohort, we estimated the annual costs for major disease categories (HIV care, other somatic care, and psychiatric care) in the period from 3 years before to 9 years after diagnosis/matching date. RESULTS: We identified 407 PLWH and 4070 persons from the background population. The total healthcare costs during the study period were approximately three times higher for PLWH compared to the non-HIV cohort (76 198 vs. 23 692). Average annual cost of hospital care, primary care and selected prescription medicine was estimated to be 6987 per year in the years after the diagnosis compared to 2083 per year in the non-HIV cohort. In PLWH, the cost of NCDs and psychiatric care was approximately two times higher than the cost of HIV care. CONCLUSION: PLWH have higher healthcare costs stemming from three areas: excess cost due to the HIV infection, the treatment of NCDs, and psychiatric care.

BACKGROUND: Kidney transplant recipients receive maintenance immunosuppressive therapy to avoid allograft rejection resulting in increased risk of infections and infection-related morbidity and mortality. Approximately 98% of adults are infected with varicella zoster virus, which upon reactivation causes herpes zoster. The incidence of herpes zoster is higher in kidney transplant recipients than in immunocompetent individuals, and kidney transplant recipients are at increased risk of severe herpes zoster-associated disease. Vaccination with adjuvanted recombinant glycoprotein E subunit herpes zoster vaccine (RZV) prevents herpes zoster in older adults with excellent efficacy (90%), and vaccination of kidney transplant candidates is recommended in Danish and international guidelines. However, the robustness and duration of immune responses after RZV vaccination, as well as the optimal timing of vaccination in relation to transplantation remain unanswered questions. Thus, the aim of this study is to characterize the immune response to RZV vaccination in kidney transplant candidates and recipients at different timepoints before and after transplantation. METHODS: The Herpes Virus Infections in Kidney Transplant Patients (HINT) study is a prospective observational cohort study. The study will include kidney transplant candidates on the waiting list for transplantation (n = 375) and kidney transplant recipients transplanted since January 1, 2019 (n = 500) from all Danish kidney transplant centers who are offered a RZV vaccine as routine care. Participants are followed with repeated blood sampling until 12 months after inclusion. In the case of transplantation or herpes zoster disease, additional blood samples will be collected until 12 months after transplantation. The immune response will be characterized by immunophenotyping and functional characterization of varicella zoster virus-specific T cells, by detection of anti-glycoprotein E antibodies, and by measuring cytokine profiles. DISCUSSION: The study will provide new knowledge on the immune response to RZV vaccination in kidney transplant candidates and recipients and the robustness and duration of the response, potentially enhancing preventive strategies against herpes zoster in a population at increased risk. TRIAL REGISTRATION: ClinicalTrials.gov (NCT05604911).

Functional antibody deficiency is clinically assessed from antibody responses to vaccination. However, diagnostic vaccination is complex and may fail in practice. We hypothesized that the levels of naturally occurring antibodies against galactose-α-1,3-galactose (αGal) may represent alternative markers of functional antibody capacity. We included data from 229 patients with suspected primary immunodeficiency in a retrospective study. Antibody levels against αGal and twelve pneumococcal serotypes were determined with solid-phase immunoassays. Pneumococcal vaccinations and treatment with normal human immunoglobulin were assessed from medical records. Anti-αGal antibody levels correlated positively with anti-pneumococcal antibody levels measured before and after pneumococcal vaccination. Contrary to the anti-pneumococcal antibody levels, the anti-αGal antibody level showed potential for predicting subsequent immunoglobulin treatment - a marker of disease severity. Naturally occurring antibodies may reflect the functional capacity tested by diagnostic vaccination but add more useful clinical data. The clinical utility of this easy test should be evaluated in prospective studies.

BackgroundMigrants face an increased risk of HIV infection and late presentation for HIV care.AimTo examine delays in HIV diagnosis, linkage to care (LTC), and risk of late presentation for migrants living with HIV in Denmark.MethodsWe conducted a population-based, nationwide study of adult migrants (n = 2,166) presenting for HIV care between 1 January 1995 and 31 December 2020 in Denmark. Time from immigration to HIV diagnosis and from diagnosis to LTC, and late presentation were assessed, stratified by migrants' geographical regions of origin, using descriptive statistics.ResultsThe demographics of the migrant population changed over time. Overall, migrants diagnosed with HIV after immigration to Denmark resided a median of 3.7 (IQR: 0.8-10.2) years in Denmark before diagnosis. Median time from HIV diagnosis to LTC was 6 (IQR: 0-24) days. Migrants diagnosed with HIV infection before immigration had a median of 38 (IQR: 0-105) days from arrival in Denmark to LTC. The corresponding median times for 2015-20 alone were 4.1 (IQR: 0.9-13.1) years, 0 (IQR: 0-8) days, and 62 (IQR: 25-152) days, respectively. The overall proportion of late presentation among migrants diagnosed with HIV after immigration was 60%, and highest among migrants from sub-Saharan Africa and East and South Asia.ConclusionHIV diagnosis is still substantially delayed in Danish migrants, while LTC is timely. The proportions with late presentation are high. These results call for targeted interventions to reduce the number of migrants with undiagnosed HIV infections and of late presenters.

BACKGROUND: The risk of skin cancer in patients with HIV has not been extensively studied. OBJECTIVE: We sought to determine the risk of skin cancer in patients with HIV and compare it with the risk in the background population. METHODS: In a matched, nationwide, population-based cohort study, we compared the risk of skin cancer in 4280 patients with HIV from the Danish HIV cohort study with a background population cohort, according to the level of immunosuppression and route of transmission. Primary outcomes were time to first basal cell carcinoma (BCC), squamous cell carcinoma (SCC), or malignant melanoma. RESULTS: Patients with HIV had an increased risk of BCC and SCC with incident rate ratios of 1.79 (95% confidence interval 1.43-2.22) and 5.40 (95% confidence interval 3.07-9.52), respectively, compared with the background population. We observed no increased risk of malignant melanoma. Low nadir CD4 cell count was associated with an increased risk of SCC. The increased risk of BCC among patients with HIV was restricted to men who had sex with men. LIMITATIONS: This study was observational and included a small number of patients with melanoma. CONCLUSION: Patients with HIV have an increased risk of BCC and SCC. Low nadir, but not current, CD4 cell count as a marker of immunosuppression was associated with an increased risk of SCC.

BACKGROUND: Invasive pneumococcal disease (IPD) is an important cause of morbidity among individuals infected with human immunodeficiency virus (HIV). We described incidence and risk factors for IPD in HIV-infected and uninfected individuals. METHODS: Nationwide population-based cohort study of HIV-infected adults treated at all Danish HIV treatment centers during 1995-2012. Nineteen population-matched controls per HIV-infected individual were retrieved. The risk of IPD was assessed using Poisson regression. RESULTS: The incidence of IPD was 304.7 cases per 100 000 person-years of follow-up (PYFU) in HIV-infected and 12.8 per 100 000 PYFU in HIV-uninfected individuals. After adjusting for confounders, HIV infection (relative risk [RR], 24.4 [95% confidence interval [CI], 23.7-25.1]), male sex (RR, 1.20 [95% CI, 1.16-1.24]), increasing age (per year) (RR, 1.03 [95% CI, 1.03-1.04]), and calendar period (pre-cART RR, 2.80 [95% CI, 2.70-2.91] compared with late cART) were significantly associated with an increased risk of IPD. Among HIV-infected individuals, male sex (RR, 1.57 [95% CI, 1.49-1.66]), smoking (RR, 1.34 [95% CI, 1.26-1.42]), and injecting drug use (RR, 2.51 [95% CI, 2.26-2.67]) were associated with an increased risk of IPD. Detectable viral loads (RR, 1.88 [95% CI, 1.79-1.98]) and a relative fall in CD4 T-cell counts were also associated with an increased risk (≥500 to 350-500 CD4 T cells/µL: RR, 1.29 [95% CI, 1.21-1.37] and <100 cells/µL: RR, 7.4 [95% CI, 6.87-8.02]). The risk of IPD declined over time, although this was not the case for IDUs where the risk remained unchanged. CONCLUSIONS: The incidence of IPD in HIV-infected individuals remained significantly higher than the incidence observed in non-HIV-infected subjects, despite the widespread use of cART. IDUs have a persistently high risk of IPD. Injecting drug use, smoking, and the receipt of cART are suitable targets for preventive measures in the future.

OBJECTIVES: The aim of this study was to assess hepatitis B virus (HBV) and hepatitis C virus (HCV) surveillance and management in HIV patients currently followed in an outpatient clinic at a Danish University Hospital. METHODS: Patient data, including demographic characteristics, clinical findings, and hepatitis serology, were reviewed at baseline. Patients with incomplete or non-updated serology within the last 2 y were retested in the next 6 months, and the results were reviewed again at follow-up. RESULTS: At baseline, 84% and 74% of the 574 HIV patients were found to have incomplete and/or non-updated HBV and HCV serology, respectively. At follow-up, updated HBV serology was achieved in 535 (93%) patients; 15 (3%) patients were found to have a chronic active infection and 156 (27%) had a resolved infection, whereas 65 (11%) were vaccinated against HBV and 299 (52%) were non-immune. No patients were found to have developed chronic HBV infection following HIV diagnosis (equal to 3649 patient-y). Updated HCV serology revealed that 25 (4%) had a chronic active HCV infection and 15 (3%) had a resolved HCV infection. The anti-HCV incidence rate was 0.27/100 patient-y. A liver pathology assessment had not been performed within the last 2 y in 80% of the HBV and 32% of the HCV co-infected patients. CONCLUSIONS: Hepatitis screening and assessment had been inadequately performed. New cases of chronic hepatitis seem to occur infrequently. However, a more proactive hepatitis surveillance and management strategy integrated into the overall HIV health care program is warranted.

INTRODUCTION: Tick-borne encephalitis (TBE) is rapidly spreading to new areas in many parts of Europe. While vaccination remains the most effective method of protection against the disease, vaccine uptake is low in many endemic countries. AREAS COVERED: We conducted a literature search of the MEDLINE database to identify articles published from 2018 to 2023 that evaluated the immunogenicity and effectiveness of TBE vaccines, particularly Encepur, when booster doses were administered up to 10 years apart. We searched PubMed with the MeSH terms 'Encephalitis, Tick-Borne/prevention and control' and 'Vaccination' for articles published in the English language. EXPERT OPINION: Long-term immunogenicity data for Encepur and real-world data on vaccine effectiveness and breakthrough infections following the two European TBE vaccines, Encepur and FSME-Immun, have shown that extending the booster interval from 3-5 years to 10 years does not negatively impact protection against TBE, regardless of age. Such extension not only streamlines the vaccination schedules but may also increase vaccine uptake and compliance among those living in endemic regions.

Respiratory syncytial virus (RSV is) a common respiratory virus responsible for considerable morbidity and mortality among infants, elderly with comorbidity, and immunocompromised adults. Two vaccines, Abrysvo and Arexvy, have been approved for prevention of severe RSV infection in adults ≥ 60 years of age. In addition, Abrysvo is approved for use during pregnancy to protect infants from RSV-associated lower respiratory tract infection. Currently, there is no national recommendation for the use of the vaccines, but vaccination of elderly at highest risk of severe RSV infection should be considered in a shared clinical decision making.

OBJECTIVE: To estimate the costs and cost-effectiveness of introducing highly active antiretroviral therapy (HAART) in Denmark based on real-world evidence for the three treatment eras pre-HAART (1985-1995), early HAART (1996-2005), and late HAART (2006-2017). METHODS: We performed a cohort study using Danish clinical and administrative registries to estimate costs, quality-adjusted life-years (QALYs), and life-years (LY) gained per person living with human immunodeficiency virus (PLHIV) in three treatment eras. The study utilized Markov modeling for a health economic evaluation, which summarized inputs from real-world evidence and estimated the cost-effectiveness in 2017 prices of the introduction of HAART in Denmark. We performed deterministic and probabilistic sensitivity analyses to assess the robustness of the results. RESULTS: The total annual costs per PLHIV increased with the introduction of HAART for the index year but decreased in the incremental years and the last year of life. The total lifetime discounted (and undiscounted) cost for an average PLHIV was 91,010 (128,981) in pre-HAART, 103,130 (199,062) in early HAART, and 126,317 (254,964) in late HAART. The estimated incremental cost-effectiveness ratios showed that early HAART was cost-effective compared with pre-HAART with an incremental cost-effectiveness ratio (ICER) of 1378 per QALY, and that late HAART was cost-effective compared with early HAART with an ICER of 7385 per QALY. Sensitivity analyses confirmed cost-effectiveness in all scenarios. CONCLUSIONS: The introduction and implementation of HAART in Danish healthcare was cost-effective, and in some scenarios, even disruptive, i.e., led to both cheaper and more effective care of PLHIV.
RESUMO
Background: Survival among people with HIV (PWH) has vastly improved globally over the last few decades but remains lower than among the general population. We aimed to estimate time trends of survival among PWH and their families from 1995 to 2021. Methods: We conducted a registry-based, nationwide, population-based, matched cohort study. We included all Danish-born PWH from 1995 to 2021 who had been on antiretroviral therapy for 90 days, did not report intravenous drug use, and were not co-infected with hepatitis C (n = 4168). We matched population controls from the general population 10:1 to PWH by date of birth and sex (n = 41,680). For family cohorts, we identified siblings, mothers, and fathers of PWH and population controls. From Kaplan-Meier tables with age as time scale, we estimated survival from age 25. We compared PWH with population controls and families of PWH with families of population controls to calculate mortality rate ratios adjusted for sex, age, comorbidities, and education (aMRR). Findings: The median age of death among PWH increased from 27.5 years in 1995-1997 to 73.9 years (2010-2014), but thereafter survival increased only marginally. From 2015 to 2021, mortality was increased among PWH (aMRR 1.87 (95% CI: 1.65-2.11)) and siblings (aMRR: 1.25 (95% CI: 1.07-1.47)), mothers (aMRR: 1.30 (95% CI: 1.17-1.43)), and fathers (aMRR: 1.15 (95% CI: 1.03-1.29)) of PWH compared to their respective control cohorts. Mortality among siblings of PWH who reported heterosexual route of HIV transmission (aMRR: 1.51 (95% CI: 1.16-1.96)) was higher than for siblings of PWH who reported men who have sex with men as route of HIV transmission (aMRR 1.19 (95% CI: 0.98-1.46)). Interpretation: Survival among PWH improved substantially until 2010, after which it increased only marginally. This may partly be due to social and behavioural factors as PWH families also had higher mortality. Funding: Preben and Anna Simonsen's Foundation and Independent Research Fund Denmark.
RESUMO
OBJECTIVES: To evaluate the relative effectiveness of high-dose quadrivalent influenza vaccine (QIV-HD) versus standard-dose quadrivalent influenza vaccine (QIV-SD) against recurrent hospitalizations and its potential variation in relation to influenza circulation. METHODS: We did a post-hoc analysis of a pragmatic, open-label, randomized trial of QIV-HD versus QIV-SD performed during the 2021-2022 influenza season among adults aged 65-79 years. Participants were enrolled in October 2021-November, 2021 and followed for outcomes from 14 days postvaccination until 31 May, 2022. We investigated the following outcomes: Hospitalizations for pneumonia or influenza, respiratory hospitalizations, cardio-respiratory hospitalizations, cardiovascular hospitalizations, all-cause hospitalizations, and all-cause death. Outcomes were analysed as recurrent events. Cumulative numbers of events were assessed weekly. Cumulative relative effectiveness estimates were calculated and descriptively compared with influenza circulation. The trial is registered at Clinicaltrials.gov: NCT05048589. RESULTS: Among 12,477 randomly assigned participants, receiving QIV-HD was associated with lower incidence rates of hospitalizations for pneumonia or influenza (10 vs. 33 events, incidence rate ratio [IRR] 0.30 [95% CI, 0.14-0.64]; p 0.002) and all-cause hospitalizations (647 vs. 742 events, IRR 0.87 [95% CI, 0.76-0.99]; p 0.032) compared with QIV-SD. Trends favouring QIV-HD were consistently observed over time including in the period before active influenza transmission; i.e. while the first week with a ≥10% influenza test positivity rate was calendar week 10, 2022, the first statistically significant reduction in hospitalizations for pneumonia or influenza was already observed by calendar week 3, 2022 (5 vs. 15 events, IRR 0.33 [95% CI, 0.11-0.94]; p 0.037). DISCUSSION: In a post-hoc analysis, QIV-HD was associated with lower incidence rates of hospitalizations for pneumonia or influenza and all-cause hospitalizations compared with QIV-SD, with trends evident independent of influenza circulation levels. Our exploratory results correspond to a number needed to treat of 65 (95% CI 35-840) persons vaccinated with QIV-HD compared with QIV-SD to prevent one additional all-cause hospitalization per season. Further research is needed to confirm these hypothesis-generating findings.
RESUMO
BACKGROUND: Efavirenz (EFV) is associated with neuropsychiatric manifestations that may compromise the course of HIV treatment. METHODS: Adverse effects leading to drug discontinuation among naïve HIV-1 patients starting on a first-line antiretroviral therapy (ART) regimen were investigated by a review of patient medical files. RESULTS: Among 276 patients, 168 (61%) were given EFV as part of the initial ART regimen. Female gender and past mental disorders were identified as predictors for selecting a non-EFV based regimen. EFV was later discontinued during the course of treatment for 90 (54%) patients. The EFV discontinuation rate due to neuropsychiatric disturbances, such as dizziness, abnormal dreams, mood changes, and anxiety, was 60%, versus 3% among patients on a third non-EFV agent based regimen (p < 0.0001). Half of the patients discontinued EFV later than 12 months after initiation of treatment, and in most cases at the discretion of the physician. Improvement in neuropsychiatric symptoms was reported by more than 90% of the patients for whom EFV discontinuation and follow-up outcome had been reported in the medical charts. CONCLUSIONS: Discontinuation of EFV occurs in more than half the treated patients. Neuropsychiatric adverse effects are by far the most common reasons for discontinuation. Discontinuation occurs late in the course of treatment suggesting persistence of central nervous system toxicity, which may impact quality of life negatively on a long-term basis. The role of EFV as a first-line ART agent should be reconsidered in the current guidelines, in particular due to the availability of other equally effective, but less toxic, ART agents.

Cutaneous larva migrans is a common disease in the tropics and among travelers. The itchy, serpentigious rash often appears within days to weeks after transmission. There are only few reported cases of late relapses. Here, we present a case of a relapse of cutaneous larva migrans more than one year after exposure.

RESUMO
Background: Despite the high frequency of international travel from Nordic countries annually, data describing demographics, patterns, and plans of travel among Nordic inhabitants are scarce. Methods: In 2018, an online questionnaire covering travel patterns, plans, and knowledge about travel-related diseases was sent to Nordic inhabitants 18-74 years of age. At-risk travelers were defined as those who had traveled outside Europe and North America during the previous 2 years. Results: Of the 5407 respondents included, 4371 (80.8%) had traveled abroad within the past 2 years. Among the respondents, 37.0% (n = 1999) were at-risk travelers. The most frequent travel destinations were Europe (n = 3907, 89.4%) and Asia (n = 1019, 23.3%). Russia/Eurasia was a more common destination for Finnish travelers than the other travelers (10.6% vs 2.3-4.1%). Most at-risk travelers had traveled for leisure/tourism (n = 1329, 66.5%). Visiting friends and relatives was more frequent among Norwegian and Swedish travelers (n = 105, 22.0% and n = 98, 19.4%, respectively) than Finnish travelers (n = 74, 12.7%). The elderly traveled often and made up 21.4% of at-risk travelers. Conclusions: Travel demographics, destinations, and future travel plans were similar across the Nordic countries. More than one third had traveled outside Europe/North America. One third were either elderly or visiting friends or relatives.
RESUMO
Immunocompromised women are at increased risk of having HPV detected and developing HPV-related diseases such as genital warts, anogenital dysplasia, and cancer. This review aims to summarize the current literature regarding the immunogenicity of the HPV vaccine in immunocompromised women and to discuss whether HPV vaccination may be able to reduce the risk of cervical dysplasia and cancer. HPV vaccination induces an immune response in these women; however, it is unknown whether vaccination is effective in reducing the risk of cervical dysplasia and cancer. Further research is needed.
