A novel enucleation- exenteration approach of the equine eye via the supraorbital fossa: an experimental and clinical study in donkeys (Equus asinus).

This study investigated the description and feasibility of a surgical procedure for enucleation-exenteration of the equine eye via the supraorbital fossa. A preliminary study was performed on both eyes of four cadaveric heads of native breed donkeys (Equus asinus) to describe the surgical anatomy and demonstrate a new supraorbital enucleation surgical approach. For the clinical study, eight donkeys were admitted for unilateral enucleation. All procedures were performed in a lateral recumbent position under the influence of inhalation anesthesia in combination with a retrobulbar nerve block. A semi-circular incision was made in the skin and fascia of the supraorbital fossa to gain access into the orbital cavity, after which the periorbital fat was dissected and removed. Bleeding was controlled by electrocautery and large blood vessels were ligated, then the eyeball was dissected sharply and freed from its bony attachment. The procedure was successfully accomplished in all clinical cases, and no significant complications occurred during or throughout the postoperative follow-up period. The initial results suggest the feasibility and safety of the supraorbital enucleation technique described in this study for equine eye enucleation. This new technique seems promising due to its feasibility, safety, and positive outcomes observed in both cadaveric and clinical studies.

Serosurvey and associated risk factors for Chlamydia abortus infection in Dromedary camels in Egypt.

Chlamydia abortus (C. abortus) is a gram-negative, obligate intracellular bacterium that causes major public health problems in human and reproductive problems in animals. The information about the epidemiology of this pathogen among camels in Egypt is very rare. This study aimed to evaluate the existence of antibodies against C. abortus in camels and assess the related risk factors for infection. A total of 410 blood samples were collected from camels from three Egyptian governorates and examined using commercial ELISA kit. The overall seroprevalence rate was 6.6% and the higher C. abortus seropositivity rate was found in Giza governorate. Location, sex and infestation by ectoparasites did not influence on the seroprevalence of the disease. In addition, age, herd size, contact with small ruminants and history of abortion were identified as risk factors for C. abortus infection according to the univariate analysis. Based on multivariate analysis, age group of 4-8 years, small herd size, contact of camels with sheep and goats, and history of abortion were found to be significant risk factors for chlamydiosis transmission in camels. These factors had odds ratios of 4.23, 3.51, 2.84, and 2.5, respectively. These results suggest that camels have a role in the epidemiology of C. abortus infection. This promotes awareness and severe public health concern about infectious camel illnesses, allowing for additional diagnostic advancements and effective management techniques to be developed.

Seroprevalence and associated risk factors for bovine leptospirosis in Egypt.

Leptospirosis is caused by pathogenic bacteria of the genus Leptospira and is one of causative agents of reproductive problems leading to negative economic impact on bovine worldwide. The goal of this study was to investigate the seroprevalence of Leptospira spp. in cattle in some governorates of Egypt's Nile Delta and assess the risk factors for infection. A total of 410 serum samples were collected from cattle and examined using microscopic agglutination test. The overall seroprevalence was 10.2% and the most prevalent serovars were Icterohaemorrhagiae, Pomona and Canicola. In addition, the potential risk factors were associated Leptospira spp. infection were age, herd size, history of abortion, presence of dogs and rodent control. Thus, leptospirosis is common in dairy cattle in the Nile Delta and  the presence of rodents in feed and dog-accessible pastures increases the risk of Leptospira spp. infection among animals.

Introducing a novel intraoral mandibular nerve block technique for loco-regional analgesia in camels (Camelus dromedarius): a cadaveric study using computed tomography.

The aim of this study was to introduce a novel intraoral technique for performing mandibular nerve blocks in dromedary camels (Camelus dromedarius). In this study, 18 adult camel skulls of varying ages and breeds were examined to determine the position of the mandibular foramen. Using a Vernier caliper, three dimensions in millimeters were measured: (1) the distance between the mandibular foramen (MF) and the caudal edge of the third molar tooth at the occlusal surface level, (2) the distance between the MF and the rostral edge border of the mandible's ramus (RER) at the occlusal surface level, and (3) the distance between the MF and the ventral margin border of the mandible (VM). The technique was evaluated using five intact camel cadaver heads (n = 5), and a total of ten mandibular nerve blocks were described. An 18-gauge 80-mm Tuohy needle was inserted into the mouth commissure and advanced caudally while injecting a saline-methylene blue solution. The accuracy of the injection was confirmed through the infiltration of the contrast dye into the target area using computed tomography (CT) and post procedural dissection. Anatomical study of the mandibular nerve site was performed to aid the blind insertion of the needle. The findings contribute to the development of veterinary anesthesia techniques and provide anatomical considerations for clinicians performing oral surgeries in sedated camels. The results demonstrated the successful implementation of the intraoral technique, highlighting its efficacy and reliability in achieving local anesthesia for oral surgeries involving the lower jaw and teeth in sedated camels. Further research studies are needed to evaluate the long-term efficacy and safety of the technique and to compare it with existing approaches.

Prevalence and potential risk factors for Cryptosporidium spp. infection in horses from Egypt.

Cryptosporidium is an intestinal protozoan that cause diarrhea in livestock all over the world and have zoonotic importance. The present study aimed to determine the prevalence of Cryptosporidium spp. in horses in Egypt and evaluate the associated risk factors. A total of 420 fecal samples were collected from three governorates (Giza, Kafr ElSheikh and Qalyubia) and examined microscopically using Ziehl-Neelsen staining method. The overall prevalence of Cryptosporidium spp. was 29% and Kafr ElSheikh governorate had the highest rate in comparison to other areas. The prevalence of Cryptosporidium spp. in examined horses had significant association with sex, age, type of management, absence of bedding and presence of dogs. The higher prevalence rate was observed in females (32.2%), age group less than two years (43.2%), mixed (grazing and stable) horses (36.1%), animals had history of diarrhea (33%), absence of bedding (35.1%) and contact with dogs (35.7%). These findings give baseline data for further research. It is necessary to establish control strategy for Cryptosporidium spp. infection in order to lower the risk of infection in animals and human.

Serosurvey and associated risk factors for Neospora caninum infection in Egyptian water buffaloes (Bubalus bubalis).

Neosporosis is a parasitic disease that causes reproductive disorders in animals, making it a barrier to maximum efficiency. The purpose of this study was to determine the seroprevalence of Neospora caninum (N. caninum) antibodies in water buffaloes from four governorates in northern Egypt. A commercial indirect-ELISA test was used to detect antibodies against N. caninum in the serum of 450 water buffaloes. The total seroprevalence of N. caninum in water buffaloes from Egypt was 31.3%, and the highest prevalence was observed in Gharbia governorate. The identified risk factors for N. caninum infections in water buffaloes were sex (OR = 1.96, 95%CI: 1.22-4.17), buffaloes more than 4 years of age ( OR = 5.80, 95%CI: 2.26-14.86), abortion in second trimester (OR = 16.48, 95%%CI: 2.99-34.03), history of abortion (OR = 3.45, 95%CI: 1.58-7.52) and contact with dogs (OR = 2.55, 95%CI: 1.51-4.32). Thus, more studies are needed to determine the role of buffaloes in the epidemiology of neosporosis in Egypt.

Seroprevalence and risk factors for Neospora spp. infection in equine in Egypt.

Neospora infections in equine are associated with reproductive disorders and neurological diseases. Nevertheless, Egypt has no epidemiological information on this parasite in equine. This study determined the prevalence of Neospora spp. infection in 325 equines from three Egyptian governorates located at Northern Egypt using cELISA. The prevalence of antibodies against Neospora spp. was 19% (95% CI: 14.09-25.05) in horse, 34.1% (95%CI: 24.92-44.69) in donkey and 26.7% (95% CI: 15.97-41.04) in mule. In comparison to horse, donkey had a considerably higher chance of contracting Neospora spp. infection (OR = 1.80, 95% CI: 0.78-4.13; P = 0.016). The risk was also higher in freely grazing animals (OR = 3.49, 95% CI: 0.95-12.78; P = 0.059). Moreover, yearling animals (12-24 months) (OR = 5.03, 95% CI: 1.51-16.80; P = 0.009) and those with natural breeding (OR = 11.80, 95% CI: 3.24-42.99, P < 0.0001) and a history of early abortion (OR = 7.04, 95% CI: 3.01-16.47; P < 0.0001) also showed a greater risk of seropositivity. The risk of Neospora infection increased significantly in equines contacted with dogs (OR = 5.16, 95% CI: 1.76-15.10; P = 0.003). This the first serological study to determine the seroprevalence of Neospora spp. in equine in Egypt. Further studies are necessary to identify the species of Neospora and to understand the role of above-mentioned risk factors in spreading of infection.

Seroprevalence of Rift Valley Fever virus in one-humped camels (Camelus dromedaries) in Egypt.

Rift Valley fever (RVF) is a mosquito-borne viral disease that affects a variety of domestic animals, including cattle, sheep, goats, and camels, and has zoonotic potential. Although the rift valley fever virus (RVFV) is usually asymptomatic in camels, it can induce abortion in some pregnant animals. In the current study, a serosurvey was carried out to investigate the prevalence of RVFV antibodies and related risk factors in camels from four Egyptian governorates. A total of 400 serum samples were examined for anti-RVFV antibodies using a competitive enzyme-linked immunosorbent assay (c-ELISA). The results revealed that the overall prevalence of RVF among examined camels was 21.5% and the disease was more prevalent in Kafr ElSheikh governorate in Nile Delta of Egypt. In addition, the age group of camels with more than 5 years (OR=4.49, 95%CI: 1.39-14.49), the female sex (OR=3.38, 95%CI: 1.51-7.58), the emaciated animals (OR=1.52, 95%CI: 0.86-2.66), the summer season's infection (OR=5.98, 95%CI: 1.79-19.93), the presence of mosquitoes (OR= 2.88, 95%CI: 1.39-5.95), and the absence of mosquitoes control (OR=3.97, 95%CI: 2.09-7.57) were identified as risk factors for RVFV infection. The results of this study support knowledge on the risk factors for RVFV infection and demonstrate that camels raising in Egypt have RVFV antibodies. Quarantine measures or vaccination program should be implemented to reduce the likelihood of RVFV introduction, dissemination among susceptible animals, and ultimately transmission to humans.

Prevalence of Cryptosporidium infection and associated risk factors in calves in Egypt.

Cryptosporidium is one of the causative parasitic agents that causes gastrointestinal diseases in calves. The parasite poses a zoonotic risk to immunocompromised individuals and children. Thus, this study aimed to determine the prevalence of Cryptosporidium infection in calves in three Egyptian governorates situated in Nile Delta and assess the associated risk factors. The Cryptosporidium oocysts were detected in 81 out of 430 calves (18.84%). In addition, the univariant analysis showed that age, feeding source, hygienic status, presence of diarrhea and contact with other animals were significantly (P < 0.05) associated with Cryptosporidium prevalence in calves. Furthermore, the risk factors related with Cryptosporidium prevalence were age (OR 1.96, 95%CI 0.97-3.94), feeding on milk and pasture (OR 2.07, 95%CI 1.15-3.72), poor hygienic condition (OR 2.25, 95%CI 1.28-3.94), presence of diarrhea (OR 2.47, 95%CI 1.23-4.96) and contact with other domestic animals (OR 2.08, 95%CI 1.24-3.50). In addition, the PCR assay targeting 18srRNA showed that the most prevalent species among calves was C. parvum. Although additional researches are required to understand the most effective steps that farmers and veterinary professionals should take to decrease the occurrence of Cryptosporidium infection.

Neospora caninum infection in dairy cattle in Egypt: a serosurvey and associated risk factors.

Neospora caninum (N. caninum) is one of the causative agents that causing cattle abortion, and severe economic losses. Due to the scarcity of data on N. caninum infection in Egyptian cattle, the purpose of this study was to estimate the seroprevalence and determine the risk factors for parasite infection. In four governorates in northern Egypt, 540 blood samples from cattle were taken, and tested using a commercial ELISA kit. The overall seroprevalence of N. caninum in examined cattle was 28.89%. A multivariate logistic regression model determined that age (OR = 2.63, P < 0.001), manual milking (OR = 1.39, P = 0.14), abortion history (OR = 2.78, P < 0.0001), repetition of estrus (OR = 2.31, P < 0.0001), and contact with dogs (OR = 2.57, P < 0.0001) were significant risk factors. The findings proved that N. caninum infection was one of the factors contributing to abortion and financial losses in dairy cattle in Egypt. Therefore, the application of sanitary security and control programs is very important in dairy farms.

Evaluation of cardiac indices using M-mode echocardiography after administration of metoclopramide and ondansetron in donkeys (Equus asinus): an experimental study.

The aim of the present study was to evaluate cardiac indices using M-mode echocardiography after the administration of metoclopramide and ondansetron in donkeys. For this purpose, 10 apparently healthy Egyptian Baladi donkeys (Equus asinus) were used in a crossover prospective study. Two trials were conducted with the administration of metoclopramide hydrochloride anhydrous at a dose of 0.25 mg Kg-1 and ondansetron hydrochloride sodium at a dose of 0.15 mg Kg-1. The control group (placebo) received a total volume of 50 mL of isotonic saline at 0.9%. An echocardiographic examination was performed using a Digital Color Doppler Ultrasound System equipped with a 2-3.9 MHz phased array sector scanner transducer. In general, the fractional shortening (FS%) was significantly affected by the time for metoclopramide (p = 0.031) and ondansetron (p = 0.047) compared with those of placebo, with treatment with metoclopramide provoking significantly higher percentages of FS% at T60 (p = 0.009) and T90 (p = 0.028) compared with those for ondansetron and placebo. The interaction of time x treatment also showed a statistically significant alteration of FS% (p < 0.05), while the values returned to the basal line at T240. Metoclopramide induced a significant decrease in E-point to septal separation (EPSS) at T90 (p = 0.005), and T240 (p = 0.007) compared with ondansetron and placebo. The time x treatment interaction also showed a significant (p < 0.05) variation in EPSS, with values returning to the basal line at T300. Mitral valve opening velocity (DE SLP) values were significantly affected by time (p = 0.004) in the metoclopramide group compared with those of ondansetron and placebo. Administration of metoclopramide and ondansetron provoked significant alterations of DE SLP at T60 (p = 0.039), T120 (p = 0.036), and T300 (p = 0.005) compared with placebo. In conclusion, caution should be exercised when administering both treatments, especially to animals with suspected cardiac problems.

Molecular prevalence and associated risk factors of Theileria annulata infections in dromedary camels in Egypt.

Theileria annulata (T. annulata) is an intracellular protozoan, transmitted by ixodid ticks of the genus Hyalomma and affects camels. There are few epidemiological data on T. annulata infection and its associated risk factors in Egyptian camels. Thus, the present study aimed to determine the prevalence of T. annulata in camels using PCR and assess the associated risk factors for infection. A total of 380 blood samples were collected from camels raising in three Egyptian governorates and examined by PCR assay targeting 30-kDa gene to detect the presence of T. annulata infection, beside statistical analysis of associated factors. The results revealed presence of T. annulata with overall prevalence of 21.1%. In addition, the univariate analysis revealed significant (P<0.05) association between prevalence of T. annulata in camels and locality, age, sex, tick infestation, and application of acaricides. Whereas the prevalence of T. annulata was higher in camels of age group >6 to 10 years (38%), females (25.7%) and in infested camels with ticks (29%) and in case of absence of acaricides application (25%). In contrast, the body condition of camels had not significant effect on prevalence of theileriosis in camels. The current study concluded that T. annulata is prevalent in Egyptian camels and that a tick control program is required to reduce the risk of infection.

Fasciola hepatica Infection in Horses in Three Governorates in Northern Egypt: Prevalence and Risk Factors.

Fasciola hepatica is a trematode parasite that affects wide range of mammalian hosts including horses. There are no epidemiological data on fasciolosis in Egyptian horses. Hence, the present study aimed to evaluate the seroprevalence of F. hepatica in horses using ELISA as well as assess the associated risk factors for fasciolosis infection. A total of 400 sera samples of horses from three Egyptian governorates were examined. The overall seroprevalence rate in horses was 13% and the disease was more prevalent in Qalubia (14.17%) and Gharbia (16.67%) which are located at Nile Delta. The likelihood of having F. hepatica seropositivity was higher in mixed-breed animals and stallions (OR = 3.97, 95%CI: 1.10-14.28 and OR = 2.07, 95%CI: 1.09-3.93, respectively), and in older horses more than 10 years (OR = 5.69, 95% CI: 1.98-16.36). Horses were more likely to be seropositive with F. hepatica when kept in outdoor housing (OR= 1.53, 95%CI: 0.78-3), during autumn (OR = 3.80, 95%CI: 1.17-12.32) and in the presence of snails (OR = 2.72, 95%CI: 1.34-5.52). Therefore, the obtained data contributes to the understanding of the epidemiology of Fasciola species, assess in establishment of management programmes to reduce disease and public health risks.

Bluetongue virus infection in cattle: serosurvey and its associated risk factors.

Bluetongue virus (BTV) is a vector-borne virus that primarily affects sheep. However, the disease is usually asymptomatic in cattle without obvious clinical signs related to BTV infection. Although there is evidence of BTV antibodies through serology in Egypt, it is still unknown whether Egyptian cattle have ever been exposed to the virus in the north or south of the country. The study's aims were to determine the seroprevalence of BTV and evaluate the potential risk factors for BTV infection in cattle in Egypt. We used a competitive ELISA to screen 690 healthy cattle for BTV-specific immunoglobulin G (IgG) antibodies in four governorates in Egypt. A total seroprevalence of BTV antibodies in examined cattle was 51.47%, 95%CI: 48.01-55.45. The odds of BTV seropositivity were higher in Aswan (OR=1.30, 95%CI: 0.71-2.36), females (OR=3.29, 95%CI: 1.87-5.79), and elder cattle >8 years (OR=12.91, 95%CI: 6.63-25.13). Moreover, cattle contacted with other animals (OR=1.40, 95%CI: 0.94-2.10), with history of abortion (OR=4.88, 95%CI: 3.14-7.59), and those living with presence of insects (OR=12.34, 95%CI: 8-19.30) were more likely to be infected with bluetongue (BT). To effectively predict and respond to a potential BTV outbreak in Egypt, surveillance for BTV infection should be expanded to cover other susceptible ruminants and the range of the insect vectors.

A century of "Camel Research": a bibliometric analysis.

Introduction: Bibliometrics is a quantitative analytic strategy used to assess the unit of publications per each field of research. Bibliometric studies are commonly employed to examine the current research climate, potential developments, and development trends in certain domains. In this work, the major contributors to camel research throughout the past century are discussed, along with the funding sources, academic institutions, scientific disciplines, and countries that contributed to "Camel Research". Methods: The Web of Science (WOS) database was used to retrieve the publications based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) instructions. Results: There are 7,593 articles dedicated to camel research on the Web of Science (as of August 1st, 2022). Three stages were involved in the publication of a study on camels. At the beginning, from 1877 to 1965, there were fewer than ten new publications per year. The second stage comprised 100 publications per year (1968-2005). Since 2010, nearly 200 new papers have been published each year. King Saud and King Faisal universities contributed > (0.08) of the total publications. While more than 1,000 funding agents were retrieved, the Natural Science Foundation of China (NSFC) showed the greatest rate of funded projects (0.17). Camel research was included in 238 scientific disciplines. The top disciplines were Veterinary Sciences (0.39), Agriculture Dairy Animal Science (0.144), and Food Science Technology (0.087). Conclusion: There has been an increase in interest in camels in recent years, but the research trends in camel health and production need greater support.

Toxoplasma gondii infection in Egyptian domestic sheep and goats: seroprevalence and risk factors.

Toxoplasma gondii is an apicomplexan protozoan parasite that has been associated with reproductive failure in small ruminants. Although T. gondii infections in ruminants and humans have been recorded in several Egypt's governorates, but little is known about the risk factors associated with T. gondii infections. In this study, 350 sheep and 290 goat serum samples from three governorates in Egypt were examined for presence of antibodies against T. gondii, and evaluate the associate risk factors for the infection. The seroprevalence in sheep and goats was 24% and 38.28%, respectively. In sheep and goats, age, sex, the presence of cats, and hygienic conditions were identified as risk factors for T. gondii infection. In addition, the prevalence rates were significantly higher in older animals more than 2 years old, females, among animals contacted with cats, and animals living in bad hygienic condition. In conclusion, sheep and goats in the examined regions are commonly infected with T. gondii. The identification of risk variables defines the sort of actions to be implemented in order to decrease, and prevent T. gondii infection in small ruminant animals and, as a result, human infection.

A century of "anticoccidial drugs": bibliometric analysis.

Publications are an important measure of scientific and technological progress. The quantitative examination of the number of publications in a certain research topic is known as bibliometrics. Bibliographic studies are widely used to analyse the condition of research, future potential, and current growth patterns in a certain topic. It can serve as a basis for making decisions and implementing strategies to achieve long-term development goals. To our knowledge, no research has been conducted in these domains; so, this work aims to employ bibliometric analysis to provide comprehensive data on publications related to anticoccidial drugs. As a result, the current study uses bibliometric analysis to track the evolution of anticoccidial drugs and its consequences in the academic and public worlds via a survey of relevant scientific and popular publications. The Dimensions database was used to retrieve the bibliographical statistics, which were then cleaned and analyzed. The data was also loaded into the VOS viewer, which generated a network visualization of the authors with the most joint articles. The investigation discovered three stages of publications and citations since the first article on anticoccidial drugs in 1949. The first stage, which ran from 1920 to 1968, was characterized by a scarcity of research articles on anticoccidial drugs. From 1969 to 2000, the second stage was marked by a stable and marginally increased number of articles. The scientific field was characterized by an increasing trend in the number of publications and their citations from 2002 to 2021. The study gave a complete list of the top anticoccidial drugs funding agents, countries, research institutes, most cited publications, and important co-authorship and partnerships. The outcomes of the study will help veterinary practitioners and researchers understand the trends and best sources of knowledge in the field of anticoccidial medications.

Safety and immunogenicity of the ChAdOx1, MVA-MERS-S, and GLS-5300 DNA MERS-CoV vaccines.

BACKGROUND: The Middle East respiratory syndrome coronavirus (MERS-CoV) is a pathogen associated with an acute respiratory infection that has a high mortality rate in humans. It was first identified in June of 2012 in the Arabian Peninsula. The success of the COVID-19 vaccines has shown that it is possible to take advantage of medical and scientific advances to produce safe and effective vaccines for coronaviruses. This study aimed to examine the safety and immunogenicity of MERS-CoV vaccines. METHODS: The research method Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was used as the guideline for this study. RevMan 5.4 software was used to perform a meta-analysis of the included studies. The safety was assessed by recording adverse events following vaccination, and the immunogenicity was assessed by using seroconversion. RESULTS: The study included five randomized controlled trials that met the inclusion criteria after screening. The studies had 173 participants and were performed in four countries. The vaccines examined were the ChAdOx1 MERS vaccine, MVA-MERS-S vaccine, and GLS-5300 DNA MERS-CoV vaccine. The meta-analysis showed no significant differences in local adverse effects (all local adverse effects and pain) or systemic adverse effects (all systemic adverse effects, fatigue, and headache) among participants in groups receiving a high-dose vaccine or a low-dose vaccine. There were, however, higher levels of seroconversion in high-dose groups than in low-dose groups (OR 0.16 [CI 0.06, 0.42, p = 0.0002]). CONCLUSION: The findings showed that high doses of current MERS-CoV vaccine candidates conferred better immunogenicity than low doses and that there were no differences in the safety of the vaccines.

Efficacy of the modified vaccinia Ankara virus vaccine and the replication-competent vaccine ACAM2000 in monkeypox prevention.

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.
