Hum Vaccin Immunother 2025; 21:2477384. [PMID: 40066621 PMCID: PMC11901372 DOI: 10.1080/21645515.2025.2477384] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2024] [Revised: 02/10/2025] [Accepted: 03/05/2025] [Indexed: 03/14/2025] Open
Abstract
The World Health Organization (WHO) has recently declared another global health emergency due to the rapidly spreading monkeypox (Mpox) outbreak in numerous African countries. To address the unmet need to contain the outbreak using the existing vaccines, this study developed a lyophilization process for an effective, scalable and affordable Mpox mRNA-LNP vaccine candidate to address the global health crisis. A comprehensive evaluation and optimization of the vaccine formulation (the type/concentration of cryoprotectants, the type/concentration of buffer system, as well as the mRNA concentration and reconstitution solvent) and the freeze-drying process parameters (freezing method, temperature, cooling rate and primary/secondary drying conditions) were conducted. The freeze-dried product exhibits a uniform appearance and a moisture content of less than 1%. Reconstitution of the lyophilized mRNA-LNP resulted in equivalent particle size/polydispersity index, encapsulation efficiency and mRNA integrity compared to that of freshly prepared mRNA-LNP. Furthermore, the lyophilization process can be scaled up 100-fold to 2000 vials/batch. Notably, the lyophilized mRNA-LNP demonstrated a storage stability of at least 12 months at 4°C, and at ambient temperature for a minimum of 8 h post-reconstitution, exhibiting minimal deterioration in product quality. The in vitro biological activity and in vivo immunogenicity of the lyophilized mRNA-LNP was comparable to that of the freshly prepared mRNA-LNP. These results provide a compelling rationale for the utilization of lyophilization technology in enhancing the accessibility of the Mpox mRNA vaccine in developing countries, a strategy that is crucial for containing the global epidemic of Mpox infection.

Promoting risk communication and community engagement during Mpox outbreak in fragile conflict zones of Eastern DRC. One Health 2025; 20:101012. [PMID: 40160936 PMCID: PMC11951864 DOI: 10.1016/j.onehlt.2025.101012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2024] [Revised: 03/10/2025] [Accepted: 03/11/2025] [Indexed: 04/02/2025] Open
Abstract
The Democratic Republic of the Congo (DRC) declared a national outbreak of monkeypox (Mpox) in December 2022, and in February 2023, an incident management system was implemented. As of May 26, 2024, the DRC had recorded 7851 cases of Mpox, with 384 fatalities. The number of confirmed cases in the province has been increasing. Of all cases, 117 (36 %) were individuals living in camps for Internally Displaced People (IDP) in North and South Kivu provinces. These provinces are currently considered as foci of the outbreak. The challenges of this outbreak in Eastern DRC, where there exist high levels of general insecurity, distrust of government and foreign actors, and ongoing violence, have contributed to widespread community resistance to potentially lifesaving interventions. The complex relationship between armed conflict and public health highlights the need for a One Health approach to address both short-term and long-term health challenges in conflict-affected regions. Armed conflict often disrupts healthcare systems, making it difficult for people to access diagnosis, treatment, and prevention services, thus leading to increased disease transmission and severe outcomes. An effective Risk Communication and Community Engagement (RCCE) strategy is the bedrock to addressing these specific needs of people in conflict zones and improving their acceptability of health interventions. A One Health approach integrating RCCE would empower communities to manage risks, identify outbreaks and avoid infected animals, improving community acceptability to public health interventions. In the delicate war zones of the DRC, conveying emergency concerns related to Mpox is a worry in terms of preserving and fostering trust in the government. This paper seeks to highlight the need for urgent intervention by the local and global public health communities to work together to put stronger policies and long-term plans into place that prioritize building a resilient healthcare system, encouraging risk communication, and engaging the community in order to combat the Mpox outbreak in the Eastern DRC fragile conflict zones.

Abstract
Mpox (Monkeypox) is a highly contagious viral disease that can be transmitted from animal-to-human or human-to-human through intimate contact, Mpox is caused by the monkeypox virus (MPXV), which is an enveloped double-stranded DNA that belongs to the genus Orthopoxvirus, Poxviridae family, and subfamily Chordopoxvirinae. Mpox cases were previously only reported in West and Central Africa, however in recent times non-endemic countries including Saudi Arabia (SA) also reported confirmed Mpox cases. The first laboratory-confirmed human Mpox case in SA was reported on 14 July 2022, since then a number of confirmed Mpox cases have been reported by WHO in SA. These confirmed Mpox cases in SA were observed among individuals with a history of visiting European Union countries. SA is not only at risk of importation of Mpox cases owing to travel to such countries, but also there are various other risk factors including geographic proximity to the African continent, trade in exotic animals, and massive inflow of tourists. Therefore, government health authorities of SA should continue to collaborate with various international health organizations including WHO to prevent, manage or monitor potential health risks at most of the entry points in SA including highways, seaports, and airports by ensuring adherence to hygiene protocols, vaccinations, and health screenings. There are a range of diagnostic tests are currently available that can be used in SA to confirm Mpox infections, including real-time PCR, loop-mediated isothermal amplification, serological testing, clustered regularly interspaced short palindromic repeat-CRISPR-associated protein (CRISPR-Cas)-based systems, whole-genome sequencing, electron microscopy, and virus isolation and culture. There is no approved treatment specifically for Mpox, however multiple approved antiviral agents for smallpox treatment were found to be useful in Mpox treatment and in the management of Mpox outbreaks, such as- trifluridine, brincidofovir, tecovirimat, and cidofovir. The aim of this review is to provide valuable insights regarding virology, pathogenesis, epidemiology, transmissions, clinical presentation, diagnostic tests, prophylactic measures and therapeutic options of Mpox from SA perspective. Moreover, a side-by-side discussion on the global trend and scenarios of Mpox has been provided for comparison and further improvement in measures against Mpox in SA.

Abstract
Monkeypox virus (MPXV) poses a global health emergency, necessitating rapid, simple, and accurate detection to manage its spread effectively. The Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) technique has emerged as a promising next-generation molecular diagnostic approach. Here, we developed a highly sensitive and specific CRISPR-Cas12a assisted nanopore (SCAN) with isothermal recombinase polymerase amplification (RPA) for MPXV detection. The RPA-SCAN method offers a sensitivity unachievable with unamplified SCAN while also addressing the obstacles of PCR-SCAN for point-of-care applications. We demonstrated that size-counting of single molecules enables analysis of reaction-time dependent distribution of the cleaved reporter. Our MPXV-specific RPA assay achieved a limit of detection (LoD) of 19 copies in a 50 μL reaction system. By integrating 2 μL of RPA amplifications into a 20 μL CRISPR reaction, we attained an overall LoD of 16 copies/μL (26.56 aM) of MPXV at a 95% confidence level using the SCAN sensor. We also verified the specificity of RPA-SCAN in distinguishing MPXV from cowpox virus with 100% accuracy. These findings suggest that the isothermal RPA-SCAN device is well-suited for highly sensitive and specific Monkeypox detection. Given its electronic nature and miniaturization potential, the RPA-SCAN system paves the way for diagnosing a wide array of other infectious pathogens at the point of care.

Abstract
Objective In May 2022, an unprecedented Mpox outbreak was reported in several non-endemic countries with unknown epidemiological links. Since May 2022, more than 20,000 cases have been reported in Europe. Spain has been the most affected country in Europe. We aim to describe the Mpox epidemiological profile in Spain, identify its outbreak risks, and describe public health interventions implemented by the Spanish authorities. Methods A literature review was conducted, using specific selection criteria to obtain relevant publications describing Mpox clinical presentation and risk factors and the public health response in Spain to the ongoing outbreak. Results 63.1% of the cases presented an anogenital rash, considered a specific and early symptom in this outbreak. Low case fatality rate is observed, mainly in risk groups, such as the immunocompromised population. Patients evolution was generally favorable, although 3-8% required hospitalization and two deaths occurred; 40% of patients were previously diagnosed with HIV infection. Most of the cases were seen among young population and concentrated in men who had sex with other men, mainly with multiple sexual partners, who did not practice safe sex such as using condoms, and those attending mass event parties. Conclusion To date, the Mpox outbreak is not considered a public health emergency of international concern. The epidemiological trend of the virus in Spain shows that public health response interventions (health education, contact tracing, vaccination, etc.) have adequately controlled the epidemic curve in high-risk populations and avoided spreading the virus to other groups within the community.

Abstract
Mpox (human mpox) is an opportunistic viral zoonosis that bears a strong resemblance to smallpox. The virus is divided into 2 distinct clades, clade I and clade II, which were originally confined to the moist forest regions of Africa. However, due to air travel and the exotic pet trade, these clades have spread globally. As immunity from smallpox vaccination declined, Mpox emerged as the most significant viral infection affecting humans within the Orthopoxvirus genus. While sporadic cases occurred worldwide, the largest Mpox outbreak outside Africa took place in 2022, prompting the WHO to declare a global public health emergency. Asia plays a pivotal role in both hosting and contributing to the spread of Mpox, driven by socio-economic factors such as high population density, widespread illegal wildlife trade, and a continuous rise in air travel. The increasing number of Mpox cases in Asia poses a significant challenge to healthcare systems, especially during times of global economic crisis. Strengthening diagnostic capabilities and infrastructure, while sustainably utilizing available resources to target high-risk populations, will be essential in addressing the Mpox threat in the region.

Abstract
The 2022 Monkeypox virus, an evolved DNA strain originating in Africa, exhibits heightened human-to-human transmissibility and potential animal transmission. Its host remains unidentified. While its initial slow transmission rate restrained global impact, 2022 saw a surge in cases, causing widespread concern in over 103 countries by September. This virus's distinctive human-to-human transmission marks a crucial shift, demanding a prompt revaluation of containment strategies. However, the host source for this shift requires urgent research attention. Regrettably, no universal preventive or curative methods have emerged for this evolved virus. Repurposed from smallpox vaccines, only some vaccinations offer a partial defense. Solely one therapeutic drug is available. The article's essence is to provide a comprehensive grasp of the virus's epidemiology, morphology, immune invasion mechanisms, and existing preventive and treatment measures. This knowledge equips researchers to devise strategies against its spread and potential public health implications.

Abstract
The 2022 mpox outbreak predominantly impacted gay, bisexual, and other men who have sex with men (gbMSM). Two models were developed to support situational awareness and management decisions in Canada. A compartmental model characterized epidemic drivers at national/provincial levels, while an agent-based model (ABM) assessed municipal-level impacts of vaccination. The models were parameterized and calibrated using empirical case and vaccination data between 2022 and 2023. The compartmental model explored: (1) the epidemic trajectory through community transmission, (2) the potential for transmission among non-gbMSM, and (3) impacts of vaccination and the proportion of gbMSM contributing to disease transmission. The ABM incorporated sexual-contact data and modeled: (1) effects of vaccine uptake on disease dynamics, and (2) impacts of case importation on outbreak resurgence. The calibrated, compartmental model followed the trajectory of the epidemic, which peaked in July 2022, and died out in December 2022. Most cases occurred among gbMSM, and epidemic trajectories were not consistent with sustained transmission among non-gbMSM. The ABM suggested that unprioritized vaccination strategies could increase the outbreak size by 47%, and that consistent importation (≥5 cases per 10 000) is necessary for outbreak resurgence. These models can inform time-sensitive situational awareness and policy decisions for similar future outbreaks.

Int J Mol Sci 2023; 24:11524.

Abstract
The exceptionally widespread outbreak of human monkeypox, an emerging zoonosis caused by the monkeypox virus (MPXV), with more than 69,000 confirmed cases in 100 non-endemic countries since 2022, is a major public health concern. Codon usage patterns reflect genetic variation and adaptation to new hosts and ecological niches. However, detailed analyses of codon usage bias in MPXV based on large-scale genomic data, especially for strains responsible for the 2022 outbreak, are lacking. In this study, we analyzed codon usage in MPXV and its relationship with host adaptation. We confirmed the ongoing outbreak of MPXVs belonging to the West Africa (WA) lineage by principal component analysis based on their codon usage patterns. The 2022 outbreak strains had a relatively low codon usage bias. Codon usage of MPXVs was shaped by mutation and natural selection; however, different from past strains, codon usage in the 2022 outbreak strains was predominantly determined by mutation pressure. Additionally, as revealed by the codon adaptation index (CAI), relative codon deoptimization index (RCDI), and similarity index (SiD) analyses, the codon usage patterns of MPXVs were also affected by their hosts. In particular, the 2022 outbreak strains showed slightly but significantly greater adaptation to many primates, including humans, and were subjected to stronger selection pressure induced by hosts. Our results suggest that MPXVs contributing to the 2022 outbreak have unique evolutionary features, emphasizing the importance of sustained monitoring of their transmission and evolution.

[PMID: 37293201 PMCID: PMC10245557 DOI: 10.3389/fcimb.2023.1188763] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Accepted: 04/26/2023] [Indexed: 06/10/2023] Open
Abstract
The increasing incidence of Monkeypox virus (Mpox) and Marburg virus (MARV) infections worldwide presents a significant challenge to global health, as limited treatment options are currently available. This study investigates the potential of several O-rhamnosides and Kaempferol-O-rhamnosides as Mpox and MARV inhibitors using molecular modeling methods, including ADMET, molecular docking, and molecular dynamics/MD simulation. The effectiveness of these compounds against the viruses was assessed using the Prediction of Activity Spectra for Substances (PASS) prediction. The study's primary focus is molecular docking prediction, which demonstrated that ligands (L07, L08, and L09) bind to Mpox (PDB ID: 4QWO) and MARV (PDB ID: 4OR8) with binding affinities ranging from -8.00 kcal/mol to -9.5 kcal/mol. HOMO-LUMO based quantum calculations were employed to determine the HOMO-LUMO gap of frontier molecular orbitals (FMOs) and to estimate chemical potential, electronegativity, hardness, and softness. Drug similarity and ADMET prediction assessments of pharmacokinetic properties revealed that the compounds were likely non-carcinogenic, non-hepatotoxic, and rapidly soluble. Molecular dynamic (MD) modeling was used to identify the most favorable docked complexes involving bioactive chemicals. MD simulations indicate that varying types of kaempferol-O-rhamnoside are necessary for successful docking validation and maintaining the stability of the docked complex. These findings could facilitate the discovery of novel therapeutic agents for treating illnesses caused by the Mpox and MARV viruses.

Travel Med Infect Dis 2023; 53:102574. [PMID: 37061148 PMCID: PMC10102563 DOI: 10.1016/j.tmaid.2023.102574] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2022] [Revised: 04/03/2023] [Accepted: 04/11/2023] [Indexed: 04/17/2023]
Abstract
BACKGROUND The re-emerging human monkeypox virus (MPXV) poses a global threat. The rising number of confirmed MPXV cases worldwide is a significant reason for concern. This study aims to investigate (1) hotel employees' knowledge in Egypt of MPXV source, signs/symptoms, transmission, prevention, and treatment, (2) the primary sources of their information about MPXV, (3) whether or not they received information about MPXV from their hotels, and (4) the differences of employees' knowledge in terms of gender, age, marital status, level of education, type of contract, professional category, hotel department, type of hotel, seniority in the hotel, and the number of hotel rooms. METHODS Using a quantitative approach, we collected data from 453 employees in Egyptian hotels via a web-based questionnaire. The survey included questions regarding the MPXV source, signs/symptoms, transmission, prevention, and treatment, as well as its primary information sources. The questionnaire also included questions regarding participants' demographics and hotel characteristics. RESULTS The findings indicated that more than half of hotel employees have inadequate knowledge of MPXV. Additionally, the majority of employees selected social media as their primary source of MPXV-related information. Surprisingly, most participants reported that their hotels neglected to provide them with the MPXV's information. Age, marital status, education, professional category, and tenure in the hotel all have a significant impact on their MPXV knowledge level. CONCLUSION The current paper presents significant implications for both theory and practice. This study provides government agencies and hotels with guidelines for preventing the outbreak of MPXV. According to our knowledge, this is the first study conducted with hotel employees in the MPXV Egyptian context.

Abstract
Monkeypox (mpox), is a disease from the Poxviridae family that can cause several serious medical issues. This mini-review sought to analyze the existing literature regarding the current mpox outbreak with a focus on the prevalence, diagnostics, and containment measures. Mpox cases have been reported to World Health Organization (WHO) from 85 Member States in all six WHO regions during the period of January 1, 2022, through August 3, 2022. Standardized or optimized guidelines for the clinical care of patients with mpox are limited, particularly in low-resource settings. In an effort to achieve guidance and meet standards, special attention should be paid to this outbreak in order to eradicate such a rare infectious disease by analyzing prevention and control measures. Patient outcomes may also be poor, and their illnesses may last for a long time. The spectrum of clinical symptoms, including complications and sequelae, as well as aspects of the illness may be indicators of sickness severity and complications; therefore, its clinical presentation must be better understood to improve containment measures. In addition, it is important to create and evaluate a standard of care that takes a variety of parameters into account, including antiviral, immune therapies, and clinical metrics that are particular to mpox. The global emergence of mpox has presented new challenges for public health and has called for further investigation into its epidemiological profile across international contexts.

Abstract
The sudden unexpected rise in monkeypox cases worldwide has become an increasing concern. The zoonotic disease characterized by smallpox-like symptoms has already spread to nearly twenty countries and several continents and is labeled a potential pandemic by experts. monkeypox infections do not have specific treatments. However, since smallpox viruses are similar to monkeypox viruses administering antiviral drugs and vaccines against smallpox could be used to prevent and treat monkeypox. Since the disease is becoming a global concern, it is necessary to analyze its impact and population health. Analyzing key outcomes, such as the number of people infected, deaths, medical visits, hospitalizations, etc., could play a significant role in preventing the spread. In this study, we analyze the spread of the monkeypox virus across different countries using machine learning techniques such as linear regression (LR), decision trees (DT), random forests (RF), elastic net regression (EN), artificial neural networks (ANN), and convolutional neural networks (CNN). Our study shows that CNNs perform the best, and the performance of these models is evaluated using statistical parameters such as mean absolute error (MAE), mean squared error (MSE), mean absolute percentage error (MAPE), and R-squared error (R2). The study also presents a time-series-based analysis using autoregressive integrated moving averages (ARIMA) and seasonal auto-regressive integrated moving averages (SARIMA) models for measuring the events over time. Comprehending the spread can lead to understanding the risk, which may be used to prevent further spread and may enable timely and effective treatment.

Abstract
Background The reemergence of the monkeypox epidemic has aroused great concern internationally. Concurrently, the COVID-19 epidemic is still ongoing. It is essential to understand the temporal dynamics of the monkeypox epidemic in 2022 and its relationship with the dynamics of the COVID-19 epidemic. In this study, we aimed to explore the temporal dynamic characteristics of the human monkeypox epidemic in 2022 and its relationship with those of the COVID-19 epidemic. Methods We used publicly available data of cumulative monkeypox cases and COVID-19 in 2022 and COVID-19 at the beginning of 2020 for model validation and further analyses. The time series data were fitted with a descriptive model using the sigmoid function. Two important indices (logistic growth rate and semi-saturation period) could be obtained from the model to evaluate the temporal characteristics of the epidemic. Results As for the monkeypox epidemic, the growth rate of infection and semi-saturation period showed a negative correlation (r = 0.47, p = 0.034). The growth rate also showed a significant relationship with the locations of the country in which it occurs [latitude (r = -0.45, p = 0.038)]. The development of the monkeypox epidemic did not show significant correlation compared with the that of COVID-19 in 2020 and 2022. When comparing the COVID-19 epidemic with that of monkeypox, a significantly longer semi-saturation period was observed for monkeypox, while a significant larger growth rate was found in COVID-19 in 2020. Conclusions This novel study investigates the temporal dynamics of the human monkeypox epidemic and its relationship with the ongoing COVID-19 epidemic, which could provide more appropriate guidance for local governments to plan and implement further fit-for-purpose epidemic prevention policies.

Abstract
In addition to the COVID-19 waves, the globe is facing global monkeypox (MPX) outbreak. MPX is an uncommon zoonotic infection characterized by symptoms similar to smallpox. It is caused by the monkeypox virus (MPXV), a double-stranded DNA virus that belongs to the genus Orthopoxvirus (OPXV). MPXV, which causes human disease, has been confined to Africa for many years, with only a few isolated cases in other areas. Outside of Africa, the continuing MPXV outbreak in multiple countries in 2022 is the greatest in recorded history. The current outbreak, with over 10 000 confirmed cases in over 50 countries between May and July 2022, demonstrates that MPXV may travel rapidly among humans and pose a danger to human health worldwide. The rapid spread of such outbreaks in recent times has elevated MPX to the status of a rising zoonotic disease with significant epidemic potential. While the MPXV is not as deadly or contagious as the variola virus that causes smallpox, it poses a threat because it could evolve into a more potent human pathogen. This review assesses the potential threat to the human population and provides a brief overview of what is currently known about this reemerging virus. By analyzing the biological effects of MPXV on human health, its shifting epidemiological footprint, and currently available therapeutic options, this review has presented the most recent insights into the biology of the virus. This study also clarifies the key potential causes that could be to blame for the present MPX outbreak and draw attention to major research questions and promising new avenues for combating the current MPX epidemic.

Abstract
The monkeypox disease is a zoonotic-infectious disease that transmits between animals and humans. It is caused by a double-stranded DNA virus belonging to the Orthopoxvirus genus that is closely related to the variola virus -the causative agent of smallpox. Although monkeypox infections were endemic to Western and Central Africa, the newly emerging monkeypox outbreak spread to more than 90 non-African countries. With the exception of the PCR-confirmed case of a return from Nigeria to the United Kingdom, the ongoing outbreak is largely unrelated to travel. In the most recent wave, cases are characteristically males in their thirties. Risk factors include close and particularly sexual contact with an infected person, and contact with fomites, infected animals or aerosolized-infectious material. Clinical diagnosis of monkeypox is confirmed with nucleic-acid amplification testing of samples originating from vesicles or genital lesions and using real-time or conventional PCR. Other methods, such as electron microscopy, immunohistochemistry, and virus culture are costly and time-consuming. In addition to timely diagnosis and contact tracing, restrictive measures to limit spread, such as isolation of infected patients, preventing contact with wild animals, and isolation of animals suspected to be viral reservoirs have shown promise. Although there are no specific treatments for monkeypox disease, the experience with smallpox suggests that the vaccinia vaccine, cidofovir, tecovirimat, and vaccinia immune globulin (IVG) may be beneficial for monkeypox treatment. In this review, we provide an update on the human-monkeypox disease with a special emphasis on its pathogenesis, prevention, diagnostics, and therapeutic measures.

Abstract
Background The burden of Human Papilloma Virus (HPV)-associated cancer remains high in developing nations.
Aims To assess the impact of self-reported awareness and attitudes on vaccination practices, and the perception on self-sampling for cervical cancer screening. Methods A 12-month survey using purposive sampling of females attending an urban public university was conducted. SPSS version 25 was used to compare the responses for students enrolled in health vs non-health related programmes.
Results Of the 290 questionnaires distributed, 240 were returned (response rate = 83%) in approximately equal proportion from the faculties of Health Science and Pharmacy (n = 127), and from the Hotel and Tourism, Business Management, and Art and Design (n = 113) faculties. About one-third (28.8%) had completed 3 shots, 19.6% received the first shot, 11.4% had scheduled appointments for first shots while 40.2% were both unvaccinated and had not scheduled any appointment. Most (71%) were aware of the HPV vaccines while 50.5% were unaware that HPV vaccines were also available for men. Students enrolled in health-related programmes were 3.2 times more perceptive to the benefits of vaccination particularly in preventing spread to their partners (OR 3.2, 95% CI 1.3–3.41, p = 0.006) than their counterparts. A weak-positive correlation was observed between knowledge and vaccination practices (r = 0.2, p = 0.001). The level of knowledge on HPV and its vaccine was greater for health-related (Mdn = 6.5) than for students of non-health related (Mdn = 1.5) programmes (U = 2790.5, p-value = 0.00). Attitudes towards immunisation were influenced by perceived benefits versus risks for side effects, cost barriers, and influences of primarily their doctors and parents. The study was limited in that relationship statuses were used to estimate sexual history as direct questions were unanswered in the pilot survey. Conclusion HPV vaccine uptake for an immunisation-targeted young female population is low despite moderate knowledge levels. It is plausible that the low rates among females enrolled in particularly the non-health programmes were impacted by misperceived vaccine-associated risks, and misconception that testing and vaccination for HPV and cervical cancer were for those married or sexually active. Self-sampling could offer a potential alternative to sampling via pelvic examination, particularly for societies where premarital sex is seen as a taboo.

Abstract
COVID-19 vaccines are possibly the most effective medical countermeasures to mitigate and ultimately bring to a halt the COVID-19 pandemic. As we transition to endemicity, inequitable access to vaccines, and particularly in low- and middle-income countries (LMICs), still poses risks of unprecedented disruptions and the emergence of viral mutations, which potentially lead to notorious vaccine-resistant variants. The missteps learned from the previous responses to the human immunodeficiency virus (HIV) and influenza outbreaks founded the hypothetical plan to ensure that vaccine accessibility to LMICs is not impeded. The SARS-CoV-2 vaccines' social promise was to lessen the underlying racial, ethnic, and geographic inequities that COVID-19 has both made apparent and intensified. Vaccine nationalism was evident throughout the COVID-19 crisis. Many high-income countries directly negotiated large advance orders for the vaccines, leaving resource-limited countries scrambling for access. This occurred despite international initiatives to structure the development and equitable distribution of vaccines, channeled through a vaccine pillar: COVID-19 Vaccines Global Access (COVAX). The serious supply shortages and national procurement methods of some countries that bypassed the vaccine pillar hindered the optimal function of COVAX in delivering timely and adequate doses to participating countries. COVAX strategized its approach by promoting fundraising, coordinating vaccine donations from countries with surplus doses, expediting reviews of vaccine candidates, and facilitating the expansion of the manufacturing capacity. While increasing capacity for production, technology transfer led to lesser siloes, enhanced manufacturing standardization, and less secrecy over production data. Ultracold storage requirements for leading vaccines were a considerable hurdle to the global immunization efforts, and particularly in LMICs with limited equipment and resources to support sophisticated cold-chain systems. Manufacturers strived to ease cold-chain restrictions on the basis of stability data submitted to national regulatory bodies. The development of single-dose vaccines offered promising solutions to simplify the administrative and logistic complexities that existed within the COVID-19 vaccination programs. As such, the requirements for both ultracold storage conditions were eased, and concerns over booster doses were addressed. To expand coverage, the dosing intervals of the Oxford/AstraZeneca vaccines were extended according to data from Phase III clinical trials on effectiveness. In addition, with the recent outbreak of monkeypox, the lessons from past experiences of curbing infectious diseases, including COVID-19, must be learned and acted upon. The review summarizes the global efforts with respect to vaccine development, production, allocation, and deployment to achieve equitable access.
