  • - Between 2010 and 2021, China reported 52,910 adverse events following immunization (AEFI) from the Hib vaccine, equating to a reporting rate of 38.10 AEFIs per 100,000 doses administered.
  • - Common reactions included fever and injection site redness/swelling, with rates of 11.93 and 9.69 per 100,000 doses, while rare reactions like anaphylactic rash occurred at very low rates (2.42 per 100,000 doses).

Introduction: Detecting poliovirus infections proves to be highly challenging due to their asymptomatic nature and infectious potential, highlighting the crucial importance of effective detection methods in the context of polio eradication efforts. In many countries, including China, the primary approach for identifying polio outbreaks has been through acute flaccid paralysis (AFP) surveillance. In this study, we conducted an evaluation spanning three decades (1993-2022) to assess the effectiveness of AFP surveillance in China.

Cannabidiol (CBD), the most abundant nonpsychoactive constituent of Cannabis sativa plant, is a promising potential pharmacotherapy for the treatment of diabetes and associated comorbidities. Previous studies have shown the potential of CBD to prevent diabetes in mice, the precise mechanisms of action remain unclear. The purpose of this study was to explore the mechanism of CBD alleviating hyperglycemia.

Importance: The Sabin-strain inactivated poliovirus vaccine (IPV) may be a tool for polio outbreak response in certain situations.

Objective: To investigate the response to a type 2 vaccine-derived poliovirus (VDPV2) outbreak.

Design, Setting, And Participants: This case series was conducted in China after a VDPV2 was detected in stool specimens from a child with acute flaccid paralysis (AFP) in Sichuan Province in 2019, 3 years after the global withdrawal of live, attenuated type 2 oral poliovirus vaccine (OPV).

The unprecedented coronavirus disease 2019 (COVID-19) pandemic has caused a disaster for public health in the last 2 years, without any sign of an ending. Various vaccines were developed rapidly as soon as the outbreak occurred. Clinical trials demonstrated the reactogenicity, immunogenicity and protection efficacy in humans, and some of the vaccines have been approved for clinical use.

RYR is a commonly used lipid-lowering dietary supplements in Asian and European countries, showing considerable benefits and low toxicity. This quantitative study aims to present high-quality evidence regarding the efficacy and safety of RYR in treating hyperlipidemia, in order to promote its clinical application. PubMed, embase, and Cochrane Central Register of Controlled Trials databases were systematically searched, and high-quality randomized controlled trials comparing RYR with non-RYR interventions were included.

Background: A rubella vaccine was licensed in China in 1993 and added to the Expanded Programme on Immunization in 2008, but a national cross-sectional serological survey during 2014 indicates that many adolescents remain susceptible. Maternal infections during the first trimester often cause miscarriages, stillbirths, and, among livebirths, congenital rubella syndrome. We aimed to evaluate possible supplemental immunisation activities (SIAs) to accelerate elimination of rubella and congenital rubella syndrome.

Objective: To evaluate the evidence for the efficacy and safety of acupuncture at Tianshu (ST25) for functional constipation (FC).

Methods: We systematically searched seven databases to identify randomized controlled trials of acupuncture at ST25 alone or in combination with conventional therapy in the treatment of FC. Risk ratios (RRs) and mean differences (MDs) were calculated using RevMan 5.

Two new lathyrane-type diterpenoids, jatropodagins A and B ( and ), and five known analogues (-), were isolated from the stems of . Their structures and absolute configurations were elucidated by spectroscopic data and calculated ECD analyses. The cytotoxicities of all the lathyrane-type diterpenoids (-) were evaluated against two human osteosarcoma cell lines (Saos-2 and MG-63).

What Is Already Known About This Topic?: After the type 2 strain of the live, attenuated poliovirus vaccine was withdrawn globally in 2016, any identification of a type 2 poliovirus is a Public Health Emergency of International Concern. A vaccine-derived type 2 poliovirus (VDPV2) was identified in Sichuan, prompting an urgent, comprehensive investigation and response.

What Is Added By This Report?: Type 2 monovalent, live, attenuated oral poliovirus vaccine (mOPV2) is being used to respond to the numerous VDPV2 outbreaks seen around the world.

In 2005, the World Health Organization (WHO) Western Pacific Region countries, including China, resolved to eliminate measles by 2012 or as soon as feasible thereafter (1). As of 2018, nine* of the 37 Western Pacific Region countries or areas had eliminated measles. China's Measles Elimination Action Plan 2006-2012 included strengthening routine immunization; conducting measles risk assessments, followed by supplementary immunization activities (SIAs) with measles-containing vaccine (MCV) at national and subnational levels; strengthening surveillance and laboratory capacity; and investigating and responding to measles outbreaks.

China has historically had high measles incidence and many associated deaths. A comprehensive measles elimination plan during 2006-2012 substantially reduced measles incidence; however, a resurgence occurred during 2013-2015. In China, measles surveillance, outbreak response, research, and program evaluation were used to strengthen routine immunization and target immunization activities for eliminating measles.

Background: Measles is among the most highly infectious human diseases. By virtue of increasingly effective childhood vaccination, together with targeted supplemental immunization activities (SIAs), health authorities in the People's Republic of China have reduced measles' reproduction number from about 18 to 2.3.

Background: Rubella-containing vaccine (RCV) became available in China in 1993 and was introduced nationwide into the Expanded Immunization Program (EPI) in 2008. We evaluated implementation and impact of RCV from 2 years prior to nationwide introduction through the 10 years after nationwide introduction.

Methods: We analyzed RCV lot-release (doses distributed) data, 1- and 2-dose RCV coverage, and rubella data from China's nationwide disease surveillance system to describe the current status and changes in rubella epidemiology between 2005 and 2017.
