Assessing the influence of the health system on access to cervical cancer prevention, screening, and treatment services at public health centers in Addis Ababa, Ethiopia.

BACKGROUND: Cervical cancer is the second leading cause of cancer death among Ethiopian women. This study aimed to assess the influence of the health system on access to cervical cancer prevention, screening, and treatment services at public health centers in Addis Ababa, Ethiopia. METHODS: This study used a cross-sectional survey design and collected data from 51 randomly selected public health centers in Addis Ababa. Open Data Kit was used to administer a semi-structured questionnaire on Android tablets, and SPSS version 26 was used to analyze the descriptive data. RESULTS: In the study conducted at 51 health centers, cervical cancer prevention and control services achieved 61% HPV vaccination for girls, 79% for cervical cancer awareness messages, 80% for precancer lesion treatment, and 71% for cervical screening of women. All health centers were performing cervical screening mostly through visual inspection with acetic acid due to the inconsistent availability of HPV DNA tests and the lack of Pap smear tests. In 94% of health centers, adequate human resources were available. However, only 78% of nurses, 75% of midwives, 35% of health officers, and 49% of health extension workers received cervical cancer training in the 24 months preceding the study. Women had provider choices in only 65% of health centers, and 86% of the centers lacked electronic health records. In 41% of the health centers, the waiting time was 30 minutes or longer. About 88% and 90% of the facilities lacked audio and video cervical cancer messages, respectively. CONCLUSION: This study revealed that the annual cervical cancer screening achievement was on track to fulfill the WHO's 90-70-90 targets by 2030. We recommend that decision-makers prioritize increasing HPV vaccination rates, enhancing messaging, reducing wait times, and implementing electronic health records to improve access to cervical cancer services in Addis Ababa.

Culturally Competent Education and Human Papillomavirus Self-Sampling Achieves Healthy People 2030 Cervical Screening Target Among Low-Income Non-Hispanic Black and Hispanic Women.

PURPOSE: Disparities in cervical cancer screening, incidence, and mortality exist in the United States. Cervical cancer incidence and mortality rates in Texas are 20% and 32% higher, respectively, than national averages. Within Texas, these rates are significantly higher among non-Hispanic (NH) Black and Hispanic women. Cervical cancer screening uptake is lower among NH Black and Hispanic women (72.9% and 75.9%, respectively) compared with White women (85.5%) in Texas. METHODS: During March-August 2023, we conducted a pilot study that offered culturally competent education and human papillomavirus (HPV) self-sampling kits to women in two public housing projects in Houston, TX, that have predominantly NH Black or Hispanic residents. Among those eligible for cervical cancer screening, 35% (n = 24) of the NH Black and 34% (n = 16) of the Hispanic women were found to be underscreened per the US Preventive Services Task Force Guideline. We recruited 40 (24 NH Black and 16 Hispanic) eligible women for our study. The study was approved by the MD Anderson institutional review board and registered with ClinicalTrials.gov (NCT04614155-March 11, 2020). RESULTS: Seventy-five percent of the NH Black and 87% of the Hispanic participants completed the HPV self-sampling procedures per protocol. Samples of 17% NH Black and 12% Hispanic participants showed a performance error. Overall, cervical cancer screening uptake improved from 65% to 91% among NH Black and from 66% to 96% among Hispanic participants. CONCLUSION: Culturally competent education and HPV self-sampling resulted in remarkable improvement in cervical cancer screening uptake among underscreened NH Black and Hispanic women residents of Houston public housing projects. Implementing this strategy could significantly reduce cervical cancer incidence and mortality among similar populations in the United States and globally.

HPV genotyping in clinical samples using long-read single-molecule real-time sequencing.

Human papillomavirus (HPV) genotyping is widely used, particularly in combination with high-risk (HR) HPV tests for cervical cancer screening. We developed a genotyping method using sequences of approximately 800 bp in the E6/E7 region obtained by PacBio single molecule real-time sequencing (SMRT) and evaluated its performance against MY09-11 L1 sequencing and after the APTIMA HPV genotyping assay. The levels of concordance of PacBio E6/E7 SMRT sequencing with MY09-11 L1 sequencing and APTIMA HPV genotyping were 100% and 90.8%, respectively. The sensitivity of PacBio E6/EA7 SMRT was slightly greater than that of L1 sequencing and, as expected, lower than that of HR-HPV tests. In the context of cervical cancer screening, PacBio E6/E7 SMRT is then best used after a positive HPV test. PacBio E6/E7 SMRT genotyping is an attractive alternative for HR and LR-HPV genotyping of clinical samples. PacBio SMRT sequencing provides unbiased genotyping and can detect multiple HPV infections and haplotypes within a genotype.

[Research progress on the differences between T and B cell responses to three different forms of human papilloma virus (HPV) vaccination].

One of the most prevalent malignancies in women is cervical cancer. Cervical cancer is mostly brought on by chronic high-risk human papillomavirus 16 (HPV16) and HPV18 infection. Currently, the widely used HPV vaccines are the bivalent Cervarix, the tetravalent Gardasil, and the 9-valent Gardasil-9.There are differences in T cell effector molecule changes, B cell antibody level, duration, age and the injection after vaccination of the three vaccines.

Cervical cancer screening practices in HIV positive females - a missing link in health care delivery in Pakistan.

Objectives: To probe cervical cancer screening practices in local women positive for human immunodeficiency virus, and to determine the cervical cytological changes in them. METHODS: The serial cross-sectional study was conducted at the Jinnah Hospital and Services Hospital, Lahore, Pakistan, from April 2019 to October 2020, and comprised female patients aged 18-45 years who were positive for human immunodeficiency virus or acquired immunodeficiency syndrome and were registered with the relevant programme being run by the provincial government in Punjab. Blood samples of all the patients were collected for the determination of human immunodeficiency virus viral load and cluster of differentiation 4+ count. Cervical smears were taken for cytopathological analysis, while the swabs were analysed for culture sensitivity. The same individuals were subjected to the same testing one year later, and the status of the disease and clinical stability or disease progression was explored. Data was analysed using SPSS 25. RESULTS: There were 150 women with mean age 32.08±7.13 years (range: 21-45 years). Age at marriage/sexual activity was 17.33±4.73 years in 15(10%) subjects. Cytological examination showed atypical squamous cells of undetermined significance in 6(4%) of the cases whereas 3(2%) cases showed atypical squamous cells, which cannot rule out high grade squamous intraepithelial lesion on cytology, while the rest were classified as negative for intraepithelial lesion or malignancy. Cervical microbial changes revealed methicillin-resistant staphylococcus aureus infection in 9(6%) cases, extended-spectrum beta-lactamase in 15(10%) cases, whereas fungal infection and trichomonas vaginalis infection were found in 30(20%) smears. There was a significant association between cluster of differentiation 4+ cell count and stability of high-risk patients (p<0.001). After one year, 84(56%) patients remained clinically stable, while 51(34%) developed some chronic illness. There was a significant association between cluster of differentiation 4+ cell count <200/mm3 and the risk of developing a chronic illness (p<0.001). CONCLUSIONS: There was a dire need to educate healthcare workers to offer regular cervical screening to patients with high-risk sexually-transmitted infections to prevent them from the morbidity and mortality related to cervical cancer.

Distribution of HPV types among women with HPV-related diseases and exploration of lineages and variants of HPV 52 and 58 among HPV-infected patients in China: A systematic literature review.

To summarize the distribution of types of human papillomavirus (HPV) associated with HPV-related diseases and investigate the potential causes of high prevalence of HPV 52 and 58 by summarizing the prevalence of lineages, sub-lineages, and mutations among Chinese women. We searched PubMed, EMBASE, CNKI, and WanFang from January, 2012 to June, 2023 to identify all the eligible studies. We excluded patients who had received HPV vaccinations. Data were summarized in tables and cloud/rain maps. A total of 102 studies reporting HPV distribution and 15 studies reporting HPV52/HPV58 variants were extracted. Among Chinese women, the top five prevalent HPV types associated with cervical cancer (CC) were HPV16, 18, 58, 52, and 33. In patients with vaginal cancers and precancerous lesions, the most common HPV types were 16 and 52 followed by 58. For women with condyloma acuminatum (CA), the most common HPV types were 11 and 6. In Chinese women with HPV infection, lineage B was the most prominently identified for HPV52, and lineage A was the most common for HPV58. In addition to HPV types 16, which is prevalent worldwide, our findings revealed the unique high prevalence of HPV 52/58 among Chinese women with HPV-related diseases. HPV 52 variants were predominantly biased toward lineage B and sub-lineage B2, and HPV 58 variants were strongly biased toward lineage A and sub-lineage A1. Further investigations on the association between the high prevalent lineage and sub-lineage in HPV 52/58 and the risk of cancer risk are needed. Our findings underscore the importance of vaccination with the nine-valent HPV vaccine in China.

Changes in intrahost genetic diversity according to lesion severity in longitudinal HPV16 samples.

Human papillomavirus type 16 (HPV16) is the most common cause of cervical cancer, but most infections are transient with lesions not progressing to cancer. There is a lack of specific biomarkers for early cancer risk stratification. This study aimed to explore the intrahost HPV16 genomic variation in longitudinal samples from HPV16-infected women with different cervical lesion severity (normal, low-grade, and high-grade). The TaME-seq deep sequencing protocol was used to generate whole genome HPV16 sequences of 102 samples collected over time from 40 individuals. Single nucleotide variants (SNVs) and intrahost SNVs (iSNVs) were identified in the viral genomes. A majority of individuals had a unique set of SNVs and these SNVs were stable over time. Overall, the number of iSNVs and APOBEC3-induced iSNVs were significantly lower in high-grade relative to normal and low-grade samples. A significant increase in the number of APOBEC3-induced iSNVs over time was observed for normal samples when compared to high-grade. Our results indicates that the lower incidence of iSNVs and APOBEC3-induced iSNVs in high-grade lesions may have implications for novel biomarkers discoveries, potentially aiding early stratification of HPV-induced cervical precancerous lesions.

Evaluation of YD MolecuTech Real HPV Assay in Comparison with Roche Cobas HPV Assay and BD Onclarity HPV Assay for Detection of HPV Infection.

OBJECTIVE: Human papillomavirus (HPV) is a double-stranded DNA virus that belongs to the papillomavirus family. High-risk (HR) genotypes of HPV are associated with cervical cancer. The combination of molecular HPV testing and cytology results in an increased detection of high-grade cervical lesions. This study compares the performance of a newly developed MolecuTech Real HPV 16/18/HR assay to that of the cobas HPV assay and Onclarity HPV Assay in Korea. METHODS: A SurePath liquid-based cytology device (BD diagnostics, NC, USA) was used to prospectively collect cervical swab specimens. Onclarity HPV Assay (Onclarity; BD diagnostics), Cobas 4800 HPV Test (Cobas; Roche, Rotkreuz, Switzerland), and MolecuTech Real HPV 16/18/HR (MolecuTech; YD, Yongin, Korea) were performed to detect HPV genotypes. RESULTS: Of the 438 cervical specimens, 13.7% showed the HR-HPV genotype. The concordance rates between Onclarity and MolecuTech, cobas and MolecuTech, and Onclarity and Cobas were 94.9% (kappa=0.754), 95.7% (kappa=0.768), and 95.5% (kappa=0.791), respectively. Moreover, no statistically significant differences in HPV genotyping results were observed in the cytology-positive specimens. CONCLUSIONS: The MolecuTech Real HPV 16/18/HR assay showed good agreement in the detection of HR HPV genotypes, and similar analytical performance for the detection of HR HPV genotypes in samples with abnormal cytological findings.

Cervical cancer: Part I human papilloma virus vaccination in Taiwan.

A significant decline in both incidence and prevalence of cervical cancers after widespread-introducing cervical screening strategy by Papanicolau test (Pap test) has been found in the world, but cervical cancer is still one of the most common female cancers, reporting the fourth prevalence and also one of the leading causes to result in main women-associated morbidity and mortality, particularly for those women living in low- and middle-income countries. Cervical cancer is one of the most important health concerns directly destroying the global health-care system, partly because of not only increasing the disability either secondary to diseases themselves of victims or mediated by treatment-related adverse events to the survivors but also acting as a leading cause of death of diseased patients worldwide, alarming the urgent need to do something to minimize the catastrophic diseases-related heavy socioeconomic burden. It is fortunate that cervical cancer is a preventable disease, based on its strong association with human papillomavirus (HPV) infection (more than 95%), particularly for those high-risk HPV (HR-HPV) and its high possibility by detecting HPV infection before the development of cervical cancer as well as an effective prevention by HPV vaccination. That is why WHO (World Health Organization) considers cervical cancer as a public problem and attempts to accelerate the elimination of cervical cancer program by three-pillar approach (90:70:90% targets), including (1) 90% of girls are fully vaccinated with HPV vaccine by 15 years of age; (2) 70% of women are screened with a high-performance test by 35 and 45 years of age and precancerous lesions are treated early; and (3) 90% of women identified with cervical diseases receive appropriate and adequate treatment. Herein, this review focuses on the HPV vaccination as Part I, including global recommendations and Taiwan government's policy for HPV vaccination.

Exploring the Role of E6 and E7 Oncoproteins in Cervical Oncogenesis through MBD2/3-NuRD Complex Chromatin Remodeling.

BACKGROUND: Cervical cancer is among the highest-ranking types of cancer worldwide, with human papillomavirus (HPV) as the agent driving the malignant process. One aspect of the infection's evolution is given by epigenetic modifications, mainly DNA methylation and chromatin alteration. These processes are guided by several chromatin remodeling complexes, including NuRD. The purpose of this study was to evaluate the genome-wide binding patterns of the NuRD complex components (MBD2 and MBD3) in the presence of active HPV16 E6 and E7 oncogenes and to determine the potential of identified genes through an experimental model to differentiate between cervical precursor lesions, with the aim of establishing their utility as biomarkers. METHODS: The experimental model was built using the CaSki cell line and shRNA for E6 and E7 HPV16 silencing, ChIP-seq, qRT-PCR, and Western blot analyses. Selected genes' expression was also assessed in patients. RESULTS: Several genes have been identified to exhibit altered transcriptional activity due to the influence of HPV16 E6/E7 viral oncogenes acting through the MBD2/MBD3 NuRD complex, linking them to viral infection and cervical oncogenesis. CONCLUSIONS: The impacted genes primarily play roles in governing gene transcription, mRNA processing, and regulation of translation. Understanding these mechanisms offers valuable insights into the process of HPV-induced oncogenesis.

High-Risk HPV CISH Detection in Cervical Biopsies with Weak and/or Focal p16 Immunohistochemical Positivity.

In cervical biopsies, for diagnosis of Human Papilloma Virus (HPV) related conditions, the immunohistochemical staining for p16 has a diagnostic value only if diffusely and strongly positive, pattern named "block-like". "Weak and/or focal (w/f) p16 expression" is commonly considered nonspecific. In our previous study, we demonstrated the presence of high-risk HPV (hrHPV) DNA by LiPa method in biopsies showing w/f p16 positivity. The aim of the present study was to investigate the presence of hrHPV-DNA by CISH in the areas showing w/f p16 expression. We assessed the presence of hrHPV16, 18, 31, 33, 51 by CISH in a group of 20 cervical biopsies showing w/f p16 expression, some with increased Ki67, and in 10 cases of block-like expression, employed as control. The immunohistochemical p16 expression was also assessed by digital pathology. hrHPV-CISH nuclear positivity was encountered in 12/20 cases of w/f p16 expression (60%). Different patterns of nuclear positivity were identified, classified as punctate, diffuse and mixed, with different epithelial distributions. Our results, albeit in a limited casuistry, show the presence of HPV in an integrated status highlighted by CISH in w/f p16 positive cases. This could suggest the necessity of a careful follow-up of the patients with "weak" and/or "focal" immunohistochemical patterns of p16, mainly in cases of increased Ki67 cell proliferation index, supplemented with molecular biology examinations.

Enhanced cervical cancer and HIV interventions reduce the disproportionate burden of cervical cancer cases among women living with HIV: A modeling analysis.

INTRODUCTION: Women living with HIV experience heightened risk of cervical cancer, and over 50% of cases in Southern Africa are attributed to HIV co-infection. Cervical cancer interventions tailored by HIV status delivered with HIV antiretroviral therapy (ART) for treatment can decrease cancer incidence, but impact on HIV-related disparities remains understudied. METHODS: Using a dynamic model calibrated to KwaZulu-Natal, South Africa, we projected HIV prevalence, cervical cancer incidence, and proportion of cancer cases among women living with HIV between 2021-2071. Relative to the status quo of moderate intervention coverage, we modeled three additive scenarios: 1) ART scale-up only; 2) expanded human papillomavirus (HPV) vaccination, screening, and treatment; and 3) catch-up HPV vaccination and enhanced screening for women living with HIV. RESULTS: Under the status quo, HIV prevalence among women aged 15+ decreased from a median of 35% [Uncertainty Range (UR): 26-42%] in 2021 to 25% [19-34%] in 2071. The proportion of cervical cancer cases that were women living with HIV declined from 73% [63-86%] to 58% [47-74%], but incidence remained 4.3-fold [3.3-5.7] that of women without HIV. ART scale-up reduced HIV prevalence in 2071, but increased the incidence rate ratio to 5.2 [3.7-7.3]. Disparities remained after expanding cancer interventions for all women (incidence rate ratio: 4.8 [3.6-7.6]), while additional catch-up HPV vaccination and screening for women living with HIV decreased the incidence rate ratio to 2.7 [1.9-3.4] in 2071. CONCLUSIONS: Tailored cervical cancer interventions for women living with HIV can counteract rising cancer incidence incurred by extended life expectancy on ART and reduce disparate cancer burden.

Human Papilloma Virus Infection and Gene Subtypes Analysis in Women Undergoing Physical Examinations: A 2015-2020 Study in Wenzhou, China.

BACKGROUND: Persistent infection with high-risk human papillomavirus (HPV) is closely related to cervical cancer. The epidemiologic characteristics of cervical HPV have regional differences. Therefore, it is necessary to develop the most favorable policies according to the actual situation of each region to prevent and reduce the prevalence of cervical cancer. This retrospective cross-sectional study investigated the prevalence, gene subtypes, and temporal trends of HPV in women undergoing physical examination in Wenzhou, to provide a decision-making basis for further prevention and control of HPV. METHODS: A total of 31 131 cervical exfoliated cell specimens obtained from physical examinations in Wenzhou, a coastal city of China, from 2015 to 2020 were collected. The age distribution was analyzed using the chi-squared test, and the time change trend was analyzed using the Mann-Kendall trend test. On this basis, the distribution characteristics of the HPV subtypes were analyzed. RESULTS: The total prevalence rate was 9.55%, and the prevalence rate in different age groups ranged from 7.77% to 14.16%. The prevalence rate in different years was 8.84%-11.83%. The prevalence rate was bimodal; it was highest in the group 25 years old, followed by the group >61 years old. The top five high-risk gene subtypes were HPV52, HPV58, HPV53, HPV16, and HPV39, whereas the low-risk subtypes were HPV61, HPV81, HPV44, HPV43, and HPV55. Of all the positive samples, 76.03% were infected with a high-risk subtype. CONCLUSION: Most female HPV patients in Wenzhou are infected with high-risk gene subtypes. Therefore, physical examination and screening for HPV should be further strengthened, and the corresponding vaccination policy should focus on high-risk gene subtypes.

RESULTS: The total prevalence rate was 9.55%, and the prevalence rate in different age groups ranged from 7.77% to 14.16%. The prevalence rate in different years was 8.84%-11.83%. The prevalence rate was bimodal; it was highest in the group less than or equal to 25 years old, followed by the group greater than 61 years old. The top five high-risk gene subtypes were HPV52, HPV58, HPV53, HPV16 and HPV39, while for low-risk were HPV61, HPV81, HPV44, HPV43 and HPV55, respectively. Of all the positive samples, 76.03% were infected with a high-risk subtype.

[Research progress of tumor-associated macrophages in cervical cancer].

Tumor-associated macrophages (TAM) can be differentiated into M1-type and M2-type macrophage phenotypes in the tumor microenvironment (TME), with M2-type macrophages playing a crucial role in malignant tumors. In cervical cancer, TAM exacerbates human papilloma virus (HPV) infection, promotes the proliferation, invasion, and metastasis of tumor cells, stimulates angiogenesis, and induces immune tolerance. TAM targeting strategies have emerged as a hot topic in cervical cancer immunotherapy.

Human papillomavirus and occupational exposure: The need for vaccine provision for healthcare providers.

To probe the understanding of healthcare providers regarding occupational exposure to human papillomavirus and their knowledge about human papillomavirus vaccination in relation to the American Society for Colposcopy and Cervical Pathology (ASCCP) recommendations. In this cross-sectional study, the healthcare providers at Mayo Clinic Arizona, Florida, and Minnesota were delivered an electronic survey. The survey was completed by 349 healthcare providers, with one respondent excluded for inconsistent entry. The mean age of respondents was 42.7 ± 10.9, and of those, 68% were female and 32% were male. Of the unvaccinated respondents, 43.3% were ≤ 45 y of age (eligible for vaccination), while those vaccinated formed 41% of the respondents. Healthcare providers are highly concerned about their cancer safety, as shown by their awareness of occupational human papillomavirus hazards and broad knowledge about vaccine efficacy. The use of personal protective equipment varied widely, including eyewear, double gloving, procedural face mask, N95 face mask, and/or nothing. Human papillomavirus and cancer risk was clearly perceived by healthcare providers. For professions, pairwise comparisons revealed that nurse practitioners, physician assistants, certified registered nurse anesthetists, and allied healthcare providers had lower scores than medical doctors. Despite the high level of understanding among healthcare providers of occupational human papillomavirus exposure, only a few of them knew of the recommendations of the ASCPP for vaccination of healthcare providers treating human papillomavirus-related diseases. In such cases, most of those surveyed embraced vaccination, which was considered 100% safe by medical doctors and allied health professionals.

Effect of the HPV vaccination programme on incidence of cervical cancer and grade 3 cervical intraepithelial neoplasia by socioeconomic deprivation in England: population based observational study.

OBJECTIVES: To replicate previous analyses on the effectiveness of the English human papillomavirus (HPV) vaccination programme on incidence of cervical cancer and grade 3 cervical intraepithelial neoplasia (CIN3) using 12 additional months of follow-up, and to investigate effectiveness across levels of socioeconomic deprivation. DESIGN: Observational study. SETTING: England, UK. PARTICIPANTS: Women aged 20-64 years resident in England between January 2006 and June 2020 including 29 968 with a diagnosis of cervical cancer and 335 228 with a diagnosis of CIN3. In England, HPV vaccination was introduced nationally in 2008 and was offered routinely to girls aged 12-13 years, with catch-up campaigns during 2008-10 targeting older teenagers aged <19 years. MAIN OUTCOME MEASURES: Incidence of invasive cervical cancer and CIN3. RESULTS: In England, 29 968 women aged 20-64 years received a diagnosis of cervical cancer and 335 228 a diagnosis of CIN3 between 1 January 2006 and 30 June 2020. In the birth cohort of women offered vaccination routinely at age 12-13 years, adjusted age standardised incidence rates of cervical cancer and CIN3 in the additional 12 months of follow-up (1 July 2019 to 30 June 2020) were, respectively, 83.9% (95% confidence interval (CI) 63.8% to 92.8%) and 94.3% (92.6% to 95.7%) lower than in the reference cohort of women who were never offered HPV vaccination. By mid-2020, HPV vaccination had prevented an estimated 687 (95% CI 556 to 819) cervical cancers and 23 192 (22 163 to 24 220) CIN3s. The highest rates remained among women living in the most deprived areas, but the HPV vaccination programme had a large effect in all five levels of deprivation. In women offered catch-up vaccination, CIN3 rates decreased more in those from the least deprived areas than from the most deprived areas (reductions of 40.6% v 29.6% and 72.8% v 67.7% for women offered vaccination at age 16-18 and 14-16, respectively). The strong downward gradient in cervical cancer incidence from high to low deprivation in the reference unvaccinated group was no longer present among those offered the vaccine. CONCLUSIONS: The high effectiveness of the national HPV vaccination programme previously seen in England continued during the additional 12 months of follow-up. HPV vaccination was associated with a substantially reduced incidence of cervical cancer and CIN3 across all five deprivation groups, especially in women offered routine vaccination.

The potential use of therapeutics and prophylactic mRNA vaccines in human papillomavirus (HPV).

Cervical cancer (CC) and other malignant malignancies are acknowledged to be primarily caused by persistent human papillomavirus (HPV) infection. Historically, vaccinations against viruses that produce neutralizing antibodies unique to the virus have been an affordable way to manage viral diseases. CC risk is decreased, but not eliminated, by HPV vaccinations. Since vaccinations have been made available globally, almost 90% of HPV infections have been successfully avoided. On the lesions and diseases that are already present, however, no discernible treatment benefit has been shown. As a result, therapeutic vaccines that elicit immune responses mediated by cells are necessary for the treatment of established infections and cancers. mRNA vaccines possess remarkable potential in combating viral diseases and malignancy as a result of their superior industrial production, safety, and efficacy. Furthermore, considering the expeditiousness of production, the mRNA vaccine exhibits promise as a therapeutic approach targeting HPV. Given that the HPV-encoded early proteins, including oncoproteins E6 and E7, are consistently present in HPV-related cancers and pre-cancerous lesions and have crucial functions in the progression and persistence of HPV-related diseases, they serve as ideal targets for therapeutic HPV vaccines. The action mechanism of HPV and HPV-related cancer mRNA vaccines, their recent advancements in clinical trials, and the potential for their therapeutic applications are highlighted in this study, which also offers a quick summary of the present state of mRNA vaccines. Lastly, we highlight a few difficulties with mRNA HPV vaccination clinical practice and provide our thoughts on further advancements in this quickly changing sector. It is expected that mRNA vaccines will soon be produced quickly for clinical HPV prevention and treatment.
