Wang B, Yin Q, Yi L, Su C, Wen Y, Qiao M, Ju Y, Liu Z, Xiong Y, Liu Z. Lyophilized monkeypox mRNA lipid nanoparticle vaccines with long-term stability and robust immune responses in mice. 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.

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 is a rapidly spreading transmissible disease induced by the monkeypox virus (MPXV), a major public health problem worldwide. The origin of monkeypox might be tracked to the continent of Africa, where it first afflicted primate species prior to spreading to the world. Severe health issues for the public have been raised as a result of the disease's current breakouts in nonendemic areas and its subsequent dissemination to several nations throughout the globe. Monkeypox spreads by having contact with infected creatures or people, as well as respiratory droplets and contaminated things. Symptoms of monkeypox in young children and adults are different. While the symptoms are similar to smallpox, monkeypox has a reduced mortality rate. Proper diagnosis, suitable care, and focused preventative efforts all depend on becoming cognizant of those distinctions. Numerous promising therapeutic approaches have been recently investigated. Antiviral drugs such as tecovirimat, cidofovir, and brincidofovir, which were initially developed to treat smallpox, were found to have been effective in treating MPXV cases. Moreover, vaccinations continue to be an important preventative step. The purpose of this article is to offer the most recent and thorough information available on monkeypox, including its possible causes, modes of transfer, and potential treatments. By identifying the distinct forms of monkeypox and exploring potential treatment options, this work contributes to the ongoing battle against MPXVs and the management of this novel viral disease. To stop the propagation of monkeypox, greater research and communication are needed to provide stronger treatments and effective vaccinations.

Abstract
The recent global resurgence of Mpox (formerly monkeypox), primarily transmitted via close contact and respiratory droplets, highlights a significant shift in its epidemiology, particularly among men who have sex with men (MSM). This resurgence underscores the need for robust public health responses and improved surveillance. This comprehensive review of current literature focuses on recent outbreaks, virology, and available treatments. Epidemiological data were gathered from various international health reports and analysed to understand transmission dynamics and outbreak patterns. Mpox, characterised by symptoms like fever and rash, has shown variable clinical presentations, particularly among immunocompromised individuals. Recent outbreaks have prompted the development of new diagnostic methods and treatments, including antivirals like Tecovirimat and vaccines such as MVA-BN. Studies have demonstrated the effectiveness of these vaccines in preventing infection, which is crucial for outbreak containment. The global response to the Mpox resurgence requires integrated strategies combining vaccination, antiviral treatments, and public health policies tailored to high-risk populations. Future efforts should focus on vaccine distribution equity and enhancing diagnostic capabilities to effectively manage and mitigate the impact of Mpox.

Abstract
The monkeypox outbreak has grown beyond the regions in which it was considered endemic. It has spread from central and west Africa to non-endemic regions like Europe, America, and other parts of the world. It has recently been classified as a public health emergency of international concern. This study evaluated the challenges faced globally and equitable access to monkeypox vaccines. Global competition has been observed in the race to obtain vaccines, with low- and middle-income countries being disadvantaged. Great inequity exists in the distribution of vaccines globally through advance purchase agreements, vaccine stockpiling, vaccine nationalism, the inequitable distribution of existing resources, and insufficient surveillance and reporting mechanisms. To address some of these challenges, there is a need for strengthening the global vaccine manufacturing capacity, targeting countries with elevated risk profiles and limited resources, strengthening surveillance systems, and addressing vaccine hesitancy.

Abstract
This review delves into the historical context, current epidemiological landscape, genomics, and pathobiology of monkeypox virus (MPXV). Furthermore, it elucidates the present vaccination status and strategies to curb the spread of monkeypox. Monkeypox, caused by the Orthopoxvirus known as MPXV, is a zoonotic ailment. MPXV can be transmitted from person to person through respiratory droplets during prolonged face-to-face interactions. While many cases of monkeypox are self-limiting, vulnerable groups such as young children, pregnant women, and immunocompromised individuals may experience severe manifestations. Diagnosis predominantly relies on clinical presentations, complemented by laboratory techniques like RT-PCR. Although treatment is often not required, severe cases necessitate antiviral medications like tecovirimat, cidofovir, and brincidofovir. Vaccination, particularly using the smallpox vaccine, has proven instrumental in outbreak control, exhibiting an efficacy of at least 85% against mpox as evidenced by data from Africa. Mitigating transmission requires measures like wearing surgical masks, adequately covering skin lesions, and avoiding handling wild animals.

Mpox knowledge and vaccination hesitancy among healthcare workers in Beijing, China: A cross-sectional survey. Vaccine X 2024; 16:100434. [PMID: 38304877 PMCID: PMC10831242 DOI: 10.1016/j.jvacx.2024.100434] [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: 10/10/2023] [Revised: 01/03/2024] [Accepted: 01/08/2024] [Indexed: 02/03/2024] Open
Abstract
Background Mpox, one of the most serious threats to global health, is now being seen in small but rising numbers in Beijing, China. Our study aimed to investigate healthcare workers' (HCWs) knowledge of Mpox and to explore reasons associated with their hesitancy to vaccinate against Mpox in Beijing, China. Methods A cross-sectional study was conducted among HCWs in Beijing from July 24 to August 2, 2023, through an online questionnaire. Participants answered questions about sociodemographic characteristics, Mpox information sources, Mpox knowledge, perception of vaccines, and attitudes toward Mpox vaccination. We used Chi-squared test to compare difference in Mpox vaccination hesitancy between different groups. Multivariable logistic regression models were applied to analyze correlates of vaccination hesitancy among HCWs. Results A total of 2331 HCWs completed the questionnaire, with an effective response rate of 92.45 % (2155/2331). Most of the HCWs in this study worked at tertiary hospitals (89.65 %), with a mean age of 36.69 ± 9.08 years. Among the 2155 participants, 52.99 % had over ten years of working experience, and 16.66 % were from high-risk departments relevant to Mpox treatment. Approximately 84.41 % knew about Mpox before this study, 80.79 % exhibited a high level of knowledge about Mpox, whereas 42.37 % were hesitant to be vaccinated against Mpox. Moreover, the hesitancy rate of HCWs in high-risk departments (47.91 %) was higher than in lower-risk departments (41.26 %). Higher educational level (aOR = 1.75, 95 %CI: 1.17-2.62), longer working years (1.71, 1.32-2.22), working at high-risk departments (1.34, 1.05-1.71), and lower level of knowledge about Mpox (1.78, 1.13-2.85) appeared as the most significant determinants of Mpox vaccination hesitancy among HCWs who knew about Mpox. For the HCWs who did not know about Mpox, longer working years (1.96, 1.02-3.78) were significant factors associated with their hesitancy. The predominant reason for hesitancy toward Mpox vaccination among HCWs encompassed apprehensions about vaccine side effects. Conclusion HCWs had good knowledge of Mpox, whereas their Mpox vaccination hesitancy was also relatively high in Beijing, China. Increasing HCWs' vaccination confidence and knowledge level about Mpox, especially for those working in high-risk departments, may be an essential way of reducing their hesitancy.

Abstract
BACKGROUND The recent re-emergence of the monkeypox (mpox) epidemic in nonendemic regions has raised concerns regarding a potential global outbreak. The mpox virus (MPV) is a smallpox-like virus belonging to the genus Orthopoxvirus (family: Poxviridae). Although studies suggest that MPV infection suppresses the Toll-like receptor-3- and tumor necrosis factor-α-related signaling pathways, whether MPV regulates other immune-related pathways remains unclear. METHODS In this study, two distinct temporal patterns were used for establishing an MPV-infected human immortal epithelial cancer cell line (HeLa). These two durations 2 and 12 h of incubation were selected to identify the coregulated genes and pathways affected by MPV infection. RESULTS The use of the Gene Ontology framework, Kyoto Encyclopedia of Genes and Genome database, and MetaCore software yielded valuable insights. Specifically, various pathways were found to be enriched in HeLa cells infected with MPV for 2 and 12 h. These pathways included Notch, CD40, CD95, hypoxia-inducible factor-1-α, interleukin (IL)- 1, IL-6, phosphoinositide 3-kinase, nuclear factor-κB, mitogen-activated protein kinase, and oxidative stress-induced signalling pathways. Clusters and pathways of metabolism and viral replication cycles were significantly associated with the 2-hour infection group. This association was identified based on the regulation of genes such as HSPG2, RHPN2, MYL1, ASPHD2, CA9, VIPR1, SNX12, MGC2752, SLC25A1, PEX19, and AREG. Furthermore, clusters and pathways related to immunity and cell movement were found to be associated with the 12-hour infection group. This association was identified based on the regulation of genes such as C1orf21, C19orf48, HRK, IL8, GULP1, SCAND2, ATP5C1, FEZ1, SGSH, TACC2, CYP4X1, MMP1, CPB1, P2RY13, WDR27, PRPF4, and ENDOD1. CONCLUSIONS This study can improve our understanding of the mechanisms underlying the pathophysiology and post-infection sequelae of mpox. Our findings provide valuable insights into the various modes of MPV infection.

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
In May 2022, World Health Organization (WHO) reported an outbreak of Mpox in several European countries which were previously Mpox free. Mpox (formerly known as monkeypox) is a zoonotic viral disease endemic in Central and West Africa. The sudden emergence of Mpox outside Africa and its subsequent rapid spread lead the WHO to declare the outbreak as Public Health Emergency of International Concern. By 15 May 2023, a total of 87,704 confirmed cases and 140 deaths had been reported from 111 countries and territories worldwide. Looking back on this outbreak 1 year later, several important questions have arisen. Here, we address these questions using the classic 5 Ws: What, When, Where, Who and Why? We discuss these questions to understand how this outbreak emerged and how it was effectively managed. We outline what needs to be done to prevent, or at least minimise, outbreaks due to emerging and re-emerging viral infections.

Abstract
Background Monkeypox, as a significant public health concern, warrants a thorough investigation into public knowledge and understanding. Especially in non-endemic areas like China, exploring the factors contributing to knowledge and understanding gaps is crucial for effective disease management and prevention strategies. Objective This study aims to assess the level of monkeypox knowledge among the Chinese public and to identify the factors that influence this knowledge, particularly focusing on the knowledge gaps between different educational groups. Methods An online cross-sectional survey was conducted involving 720 participants stratified by age, between July and August 2023. The survey used a modified monkeypox knowledge questionnaire, and hierarchical regression analysis was employed to analyze the data. Results The study revealed a significant knowledge gap in the understanding of monkeypox among the Chinese public. Key factors influencing this knowledge included educational level, perceived relevance of information, interpersonal communication, and exposure to social media and official health websites. Notably, exposure to social media was found to widen the knowledge gap between different educational groups, with its positive impact more pronounced in individuals with at least a junior high school education. Conclusion The findings emphasize the need for varied communication strategies to effectively disseminate information about monkeypox and bridge the existing knowledge gaps. Tailoring health communication to different educational levels and utilizing diverse information sources are crucial for improving public understanding and containment of monkeypox.

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.

Abstract
Monkeypox (Mpox) is a transmissible infection induced by the Monkeypox virus (a double-stranded DNA virus), recognised under the family orthopoxvirus genus. Monkeypox, like endemic diseases, is a substantial concern worldwide; thus, comprehending the pathogenesis and mutagenesis of amino acids is indispensable to combat the infection. According to the World Health Organization's report, about 89 thousand cases with 160 mortalities have been reported from 114 countries worldwide. The conventional orthopoxvirus vaccines developed on live attenuated viruses exempted any clinical validation from combating monkeypox due to inadequate immunogenicity, toxicity, instability, and multiple doses. Therefore, novel drug delivery systems come into the conception with high biological and mechanical characteristics to address the resurgence of Global Monkeypox. The edges of metallic biomaterials, novel molecules, and vaccine development in targeted therapy increase the modulation of the immune response and blockage of host-virus interaction, with enhanced stability for the antigens. Thus, this review strives to comprehend the viral cell pathogenesis concerning amino acid mutagenesis and current epidemiological standards of the Monkeypox disease across the globe. Furthermore, the review also recapitulates the various clinical challenges, current therapies, and progressive nanomedicine utilisation in the Monkeypox outbreak reinforced by various clinical trial reports. The contemporary challenges of novel drug delivery systems in Monkeypox treatment cannot be overlooked, and thus, authors have outlined the future strategies to develop successful nanomedicine to combat monkeypox. Future pandemics are inevitable but can be satisfactorily handled if we comprehend the crises, innovate, and develop cutting-edge technologies, especially by delving into frontiers like nanotechnology.

Abstract
The re-emergence of the monkeypox virus has come with many burdens on nations. This is partly after the effects of the coronavirus disease 2019 virus is subsiding. The burden of the monkeypox virus is seen even more in developing and third-world countries. Beyond the monkeypox virus re-emergence, there have also been several other viruses within the world and in Nigeria. This study assessed Nigeria's preparedness and response to the re-emergence of the monkeypox virus. The Nigerian Government showed its preparedness in the fight against the monkeypox virus by bringing together both Human and Animal Health Sectors. It ensured interventions and programs were created. Among these is Surveillance Outbreak, Response, Management, and Analysis System, a Surveillance and monitoring intervention to manage any outbreak. A second intervention is the Emergency Operation Center. It is recommended that vaccines should be made available, personnel should be adequately trained, and improved diagnostics equipment be made available. Nigeria has had cases of the monkeypox virus, and we wanted to see how far it has come in its preparedness and how it will respond if the need arises. This study reviewed existing literature on Nigeria's battle against the monkeypox virus in times past, the actions taken, and the programs developed.

Abstract
Monkeypox virus (MPXV) is an emerging zoonotic virus that belongs to the Orthopoxvirus genus and presents clinical symptoms similar to those of smallpox, such as fever and vesicular-pustular skin lesions. However, the differential diagnosis between smallpox and monkeypox is that smallpox does not cause lymphadenopathy but monkeypox generates swelling in the lymph nodes. Since the eradication of smallpox, MPXV has been identified as the most common Orthopoxvirus to cause human disease. Despite MPXV being endemic to certain regions of Africa, the current MPXV outbreak, which began in early 2022, has spread to numerous countries worldwide, raising global concern. As of the end of May 2023, over 87,545 cases and 141 deaths have been reported, with most cases identified in non-endemic countries, primarily due to human-to-human transmission. To better understand this emerging threat, this review presents an overview of key aspects of MPXV infection, including its animal reservoirs, modes of transmission, animal models, epidemiology, clinical and immunological features, diagnosis, treatments, vaccines, and prevention strategies. The material presented here provides a comprehensive understanding of MPXV as a disease, while emphasizing the significance and unique characteristics of the 2022 outbreak. This offers valuable information that can inform future research and aid in the development of effective interventions.

[PMID: 37220529 PMCID: PMC10195808 DOI: 10.1016/j.cegh.2023.101313] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 05/01/2023] [Accepted: 05/10/2023] [Indexed: 05/25/2023] Open
Abstract
Background The Mpox outbreak awakened countries worldwide to renew efforts in epidemiological surveillance and vaccination of susceptible populations. In terms of Mpox vaccination, various challenges exist in the global south, which impede adequate vaccine coverage, especially in Africa. This paper reviewed the situation of Mpox vaccination in the global south and potential ameliorative approaches. Methods A review of online literature from PubMed and Google Scholar concerning Mpox vaccination in countries belonging to the 'global south' category was done between August and September, 2022. The major focus areas included inequity in global vaccine distribution, challenges impeding vaccine coverage in the global south, and potential strategies for bridging the gap in vaccine equity. The papers that met the inclusion criteria were collated and narratively discussed. Results Our analysis revealed that, while the high-income countries secured large supplies of the Mpox vaccines, the low- and middle-income countries were unable to independently access substantial quantities of the vaccine and had to rely on vaccine donations from high-income countries, as was the case during the COVID-19 pandemic. The challenges in the global south particularly revolved around inadequate vaccine production capacity due to lack of qualified personnel and specialized infrastructure for full vaccine development and manufacturing, limited cold chain equipment for vaccine distribution, and consistent vaccine hesitancy. Conclusion To tackle the trend of vaccine inequity in the global south, African governments and international stakeholders must invest properly in adequate production and dissemination of Mpox vaccines in low- and middle-income countries.

Efficacy of the modified vaccinia Ankara virus vaccine and the replication-competent vaccine ACAM2000 in monkeypox prevention. Int Immunopharmacol 2023; 119:110206. [PMID: 37087871 PMCID: PMC10120163 DOI: 10.1016/j.intimp.2023.110206] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 04/13/2023] [Accepted: 04/14/2023] [Indexed: 04/25/2023]
Abstract
BACKGROUND Recently, there has been an uptick in reported cases of monkeypox (Mpox) in Africa and across the globe. This prompted us to investigate the efficacy of the two vaccines that can prevent Mpox, the modified vaccinia Ankara virus (MVA) vaccine and ACAM2000 vaccine. We analyzed them to determine their rates of humoral cell responses, adverse events, and rash reactions and used these factors as the primary indicators. METHODS This study adapted primary data obtained from the Medline, Google Scholar, and Cochrane Library databases. We included a total of eight studies, three of which explored the ACAM2000 vaccine and five of which explored the JYNNEOS MVA vaccine. RESULTS There were significant differences in the rates of humoral responses after inoculation by the two vaccines. JYNNEOS MVA vaccine immunization resulted in a statistically significant increased humoral immune response with an effect size of 81.00 (42.80, 119.21) at a 95% CI and a rash reaction with an effect size of 96.50 (42.09, 235.09.21) at a 95% CI. ACAM2000 resulted in a lesser increase in neutralizing antibodies than JYNNEOS MVA vaccine. Similar findings were identified for the rates of adverse reactions, but the difference was not statistically significant. The differences in rash reaction rates in the two vaccination groups were also not statistically significant. CONCLUSION ACAM2000 and JYNNEOS vaccines have proven to be efficient in preventing Mpox even though variations exist in their modes of action and associated significant effects. The nonreplicating nature of JYNNEOS prevents the occurrence of the adverse effects seen with other vaccines.

Abstract
Background: The outbreak of monkeypox was declared a global public health emergency by the World Health Organization on 23 July 2022. There have been 60,000 cases reported worldwide, most of which are in places where monkeypox has never been seen due to the travel of people who have the virus. This research aims to evaluate the general Arabic population in regard to the monkeypox disease, fears, and vaccine adoption after the WHO proclaimed a monkeypox epidemic and to compare these attitudes to those of the COVID-19 pandemic. Methods: This cross-sectional study was performed in some Arabic countries (Syria, Egypt, Qatar, Yemen, Jordan, Sudan, Algeria, and Iraq) between 18 August and 7 September 2022. The inclusion criteria were the general public residing in Arabic nations and being older than 18. This questionnaire has 32 questions separated into three sections: sociodemographic variables, prior COVID-19 exposure, and COVID-19 vaccination history. The second portion assesses the knowledge and anxieties about monkeypox, while the third section includes the generalized anxiety disorder (GAD7) scale. Logistic regression analyses were performed to compute the adjusted odds ratios (aOR) and their confidence intervals (95%CI) using STATA (version 17.0). Results: A total of 3665 respondents from 17 Arabic countries were involved in this study. Almost two-thirds (n = 2427, 66.2%) of the participants expressed more worry about COVID-19 than monkeypox diseases. Regarding the major cause for concern about monkeypox, 39.5% of participants attributed their anxiety to the fear that they or a member of their family may contract the illness, while 38.4% were concerned about monkeypox becoming another worldwide pandemic. According to the GAD 7 score, 71.7% of the respondents showed very low anxiety toward monkeypox and 43.8% of the participants scored poor levels of knowledge about monkeypox disease. Participants with previous COVID-19 infection showed a 1.206 times greater acceptance to receive the monkeypox vaccine than those with no previous infection. A 3.097 times higher concern for monkeypox than COVID-19 was shown by the participants who perceived monkeypox as dangerous and virulent than those who did not. Participants who have a chronic disease (aOR: 1.32; 95%CI: 1.09–1.60); participants worried about monkeypox (aOR: 1.21; 95%CI: 1.04–1.40), and perceived monkeypox as a dangerous and virulent disease (aOR: 2.25; 95%CI: 1.92–2.65); and excellent knowledge level (aOR: 2.28; 95%CI: 1.79–2.90) have emerged as significant predictors. Conclusions: Our study reported that three-fourths of the participants were more concerned about COVID-19 than monkeypox disease. In addition, most of the participants have inadequate levels of knowledge regarding monkeypox disease. Hence, immediate action should be taken to address this problem. Consequently, learning about monkeypox and spreading information about its prevention is crucial.

Abstract
Monkeypox (MPX) is a zoonotic disease that is endemic to the western and central regions of Africa and it is caused by monkeypox virus (MPXV), which is classified as a member of the Poxviridae family, specifically the Chordopoxvirinae subfamily, and the Orthopoxvirus genus. The current multiregional outbreak of MPX, which started in May of 2022, has since swiftly spread across the globe and thus has been declared a global public health emergency by the World Health Organization (WHO). Protective immunity against MPXV can be achieved by administering a smallpox vaccination, as the two viruses share antigenic properties. Although smallpox was declared eradicated in 1980, the vaccine campaign was halted the following year, leaving the population with significantly less immunity than it had before. The potential for human-to-human transmission of MPXV has grown as a result. Due to the lack of a particular treatment for MPX infection, anti-viral medications initially designed for the smallpox virus are being employed. However, the prognosis for MPX may vary depending on factors like immunization history, pre-existing illnesses, and comorbidities, even though the majority of persons who develop MPX have a mild, self-limiting illness. Vaccines and antiviral drugs are being researched as potential responses to the latest 2022 MPX epidemic. The first-generation smallpox vaccinations maintained in national stockpiles of several countries are not recommended due to not meeting the current safety and manufacturing criteria, as stated by the WHO. Newer, safer (second- and third-generation) smallpox vaccines, such as JYNNEOSTM, which has been licensed for the prevention of MPX, are indicated as potentially useful in the interim guideline. Studies on vaccines and antiviral drugs are still being investigated as possible remedies to the recent MPX outbreak. This mini-review article serves as a retrospective look at the evolution of smallpox vaccines from their inception in the 1700s to the current trends up to the end of year 2022, specifically for developing monkeypox vaccines.

COVID-19 Vaccination Prioritization Strategies in Malaysia: A Retrospective Analysis of Early Evidence. Vaccines (Basel) 2022; 11:vaccines11010048.

Abstract
The coronavirus disease 2019 (COVID-19) that can cause extreme acute respiratory syndrome has posed a catastrophic threat to public health. The vaccines had indeed restored optimism and, after more than two years of battling the pandemic, there is renewed hope for the transition to endemicity. At the start of vaccination efforts, when supply shortages of vaccines were inevitable, every nation determined the high-risk population groups to be given priority for the COVID-19 vaccines. In this paper, the characteristics of the initial COVID-19 vaccine recipients in Malaysia are described. In line with the policies of many other countries, Malaysia firstly inoculated frontline healthcare workers, and subsequently the list of front liners grew to include defense and security personnel and those involved in the provision of essential services. People with disabilities or those with special needs and several underlying medical conditions that increased their risk of developing severe COVID-related illnesses were included in the priority categories. These included patients with severe lung disease, chronic heart disease, chronic kidney disease, chronic liver disease, neurological disease, diabetes mellitus and obesity in adults, splenic dysfunction, and severe mental illness. With little information and under circumstances of great uncertainty, the Health Ministry of a middle-income country had developed a vaccination priority-list based on the disease's epidemiology and clinical data, vaccine type, operational considerations, and risk evaluation. Early evidence was presented and suggested that the full vaccination with any of the three predominant vaccines (AZD1222, BNT162b2, and CoronaVac) in the country had been highly effective in preventing COVID-19 infections, COVID-19-related ICU admissions, and death. As many SARS-CoV-2 variants of concern (VoC), such as the Omicron BA.2/4/5, are emerging, future vaccination strategies may necessitate the need to change the immunogen of the vaccine, as well as considerations for when to give high-risk groups booster injections. These considerations are valuable for future planning by policymakers and healthcare providers to make vaccination policy and decisions, especially for the inclusion of the COVID-19 vaccines into national immunization programs.

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
The recent emergence of monkeypox (MPX) has created a global threat. The number of infected and suspected cases of MPX is increasing in different parts of the world, especially in non-African countries. However, vaccines are available to fight against this disease. It has been observed that smallpox vaccines can be used to protect against MPX. The present article highlights the significant points and various issues for vaccines and vaccinations that should be considered related to MPX. This paper illustrates current vaccines for smallpox that can be utilized to protect against MPX infection. The article also describes the different significant research on MPXV, especially smallpox vaccines, and its outcome in MPX infection. We have also tried to depict the smallpox vaccination eradication model through the statistical interface using smallpox eradication data from Central and West Africa between 1967 and 1972. We suggest that these models might be helpful for the eradication of MPX in the middle to low-economic countries. Simultaneously, we have also discussed vaccination preparedness in different countries like the USA, UK, Canada, Denmark, Germany, etc. Our report might be helpful to scientists and policymakers in understanding the vaccines and vaccination against MPX and formulating effective strategies to fight against the disease.

Abstract
Human monkeypox, caused by monkeypox virus, has spread unprecedentedly to more than 100 countries since May 2022. Here we summarized the epidemiology of monkeypox through a literature review and elucidated the risks and elimination strategies of this outbreak mainly based on the summarized epidemiology. We demonstrated that monkeypox virus became more contagious and less virulent in 2022, which could result from the fact that the virus entered a special transmission network favoring close contacts (i.e., sexual behaviors of men who have sex with men outside Africa) and the possibility that the virus accumulated a few adaptive mutations. We gave the reasons to investigate whether cattle, goats, sheep, and pigs are susceptible to monkeypox virus and whether infection with monkeypox virus could be latent in some primates. We listed six potential scenarios for the future of the outbreak (e.g., the outbreak could lead to endemicity outside Africa with increased transmissibility or virulence). We also listed multiple factors aiding or impeding the elimination of the outbreak. We showed that the control measures strengthened worldwide after the World Health Organization declared the outbreak a public health emergency of international concern (PHEIC) could eliminate the outbreak in 2022. We clarified eight strategies, i.e., publicity and education, case isolation, vaccine stockpiling, risk-based vaccination or ring vaccination, importation quarantine, international collaboration, and laboratory management, for the elimination of the outbreak.
