The Current State and Progress of Mpox Vaccine Research

On July 23,2022,the World Health Organization(WHO)declared the monkeypox(mpox)outbreak a“Public Health Emergency of International Concern.”Since 2022,outbreaks of mpox in many countries around the world have primarily resulted in fatalities among immunocompromised individuals,such as untreated HIV/AIDS patients.Since the eradication of smallpox was declared by the WHO in 1980,the global vaccination against smallpox has been gradually discontinued.China also stopped routine smallpox vaccination in 1981.The protective effect of the smallpox vaccine has decreased over time due to aging and declining immunity in those who were vaccinated.For individuals,timely vaccination against smallpox is an effective means of protection against mpox.However,due to safety concerns with the smallpox vaccine and the limitations of current mpox vaccines,there is no vaccine that is safe,effective,and has low side effects applied in clinical settings.This article provides a comprehensive review of the development of mpox virus(MPXV)vaccines,their application in special populations,and the current state of vaccine research,considering the etiology,transmission,and prevention of the MPXV.Vaccination,as an effective method of epidemic prevention,can provide long-term immune protection and effectively reduce the severity of infection.However,as there is no licensed specific MPXV vaccine available globally,the vaccines currently used for mpox prevention are mostly smallpox vaccines.These smallpox vaccines can offer some degree of protection against mpox by activating cross-protection in the body.

An Outbreak of Serogroup Y Meningococcal Meningitis in a Private Secondary Vocational School-Guangzhou City,Guangdong Province,China,2023

What is already known about this topic?The inclusion of meningococcal vaccines in the National Immunization Program(NIP)over several years has significantly reduced the incidence of meningococcal meningitis in China to historic lows.Worldwide,there has been a diversification of meningococcal serogroups,leading to a shift in dominant serogroups in China from serogroup A to serogroups C and B,accompanied by a rise in reports of serogroups Y and W.What is added by this report?An outbreak of serogroup Y Neisseria meningitidis(Nm)in a secondary vocational school involved a single confirmed severe case and 24 individuals with laboratory-confirmed Nm carriage.Epidemiological investigation revealed that the outbreak was localized to the classroom of the confirmed case.Prolonged close contact within a confined space was identified as a significant risk factor for Nm transmission.The genotype sequence identified was type 1655(ST-1655),which is categorized under clonal complex 23(CC-23)and bears resemblance to 8 previously confirmed cases of serogroup Y meningococcal meningitis within Guangdong Province.This suggests that serogroup Y infections continue to sporadically emerge and have become prevalent strains.What are the implications for public health practice?This outbreak underscores the critical need to enhance surveillance of meningococcal serogroups and population carrier,and advocate for vaccination with MenY-containing vaccines.

Genetic Insights into Glycine’s Protective Role Against CAD—European and East Asia,2015 and 2020

Introduction:The purpose of this study is to examine the potential causal relationship between levels of circulating glycine and coronary artery disease(CAD)using a two-step Mendelian randomization(MR)analysis.Methods:We analyzed data from genome-wide association studies(GWAS)conducted on European and East Asian populations.To assess the causal effects of circulating glycine levels on the risk of CAD.We used the inverse-variance weighting(IVW),weighted median(WM),MR-Egger,and Mendelian Randomization Pleiotropy RESidual Sum and Outlier(MR-PRESSO)methods.Furthermore,we conducted mediation analysis to investigate the contribution of blood pressure and other cardiovascular disease-related traits.Results:The two-step Mendelian randomization analysis revealed that higher levels of glycine in the blood were associated with a reduced risk of CAD in Europeans[odds ratio(OR)=0.84,95%confidence interval(CI):0.72,−0.98;P=0.029]and East Asians:(OR=0.76,95%CI:0.66,−0.89;P=3.57×10−4).Sensitivity analysis confirmed the robustness of these findings.Additionally,our results suggest that about 6.06%of the observed causal effect is mediated through genetically predicted systolic blood pressure(SBP)in the European population.Discussion:Our results contribute to the current knowledge regarding the involvement of glycine in the progression of CAD,and provide valuable methodological insights for the prevention and treatment of this condition.
