Background Immunization is a cornerstone of public health. Despite great success, China’s National Immunization Program (NIP) faces challenges, such as the integration of several World Health Organization-recommended vaccines and other systemic issues. The Innovation Laboratory for Vaccine Delivery research (VaxLab), supported by the Bill & Melinda Gates Foundation and established in 2021 at Duke Kunshan University, focuses on enhancing China’s NIP through research and policy advocacy. This editorial aims to summarize the key findings of the manuscripts published in the collection contributed by VaxLab team and set the future research *** findings The collection contains eleven manuscripts discussing China’s immunization landscape and strategies to improve coverage, particularly for non-NIP vaccines like human papillomavirus vaccine (HPV), pneumococcal conjugate vaccine (PCV),Haemophilus influenzae type b vaccine (Hib), and rotavirus vaccines. Key findings include: (i) The COVID-19 vaccination campaign demonstrated China’s capacity for rapid, large-scale immunization efforts, suggesting potential for broader vaccine coverage improvements; (ii) Efforts in combating cervical cancer through the HPV vaccine indicate progress but also highlight challenges like vaccine supply and equitable access; (iii) The lag in adopting higher-valent paediatric combination vaccines in China needs attention to address regulatory and health system hurdles; (iv) Disparities in access to non-NIP vaccines underscore the need for government initiatives to improve vaccine coverage, especially for remote areas and marginalized populations; (v) Original studies emphasize the influence of caregivers’ knowledge, health workers’ financial incentives, and concerns about vaccine efficacy on immunization rates; (vi) Case studies from the Weifang City of China and Indonesia to introduce PCV offer insights on successful vaccine introduction strategies and the impact of innovative financing and g

Objective: This study aimed to provide a comprehensive overview of the global burden of esophageal cancer(EC) and determine the temporal trends and factors influencing changes in the global ***: The latest incidence and mortality data for EC worldwide were obtained from globalCAN 2022. The mortality and disability-adjusted life years(DALYs) rates for EC from 1990±2019 were sourced from the 2019 global Burden of Diseases. Trends in EC mortality and DALYs attributable to 11 risk factors or clusters of risk were analyzed using the joinpoint regression model. The trends in age-related EC burden were assessed using a decomposition ***: An estimated 511,054 new cases of EC were diagnosed in 2022 with 445,391 deaths worldwide. Approximately 75% of cases and deaths occurred in Asia. Nearly 50% of global EC deaths and DALYs were attributed to tobacco use in men in 2019, while 20% were attributed to high body mass index(BMI) in women. From 1990±2019, EC deaths and DALYs attributable to almost all risk factors had declining trends, while EC deaths and DALYs attributed to high BMI in men had upward trends. The age-related EC burden exhibited an upward trend driven by population growth and aging, which contributed to 307.4 thousand deaths and 7.2 million DALYs due to ***: The EC burden remains substantial worldwide. Effective tobacco and obesity control measures are critical for addressing the risk-attributable burden of EC. Population growth and aging pose challenges for EC prevention and control efforts.

Objective: Liver cancer is a major health concern globally and in China. This analysis investigated deaths and disability-adjusted life years(DALYs) with respect to etiologies and risk factors for liver cancer in China and ***: global and China-specific data were collected on liver cancer deaths, DALYs, and age-standardized rates(ASRs) from the global Burden of Disease Study 2019 database. Liver cancer etiologies were classified into five groups and risk factors were categorized into three levels. Each proportion of liver cancer burden was calculated in different geographic regions. The joinpoint regression model were used to assess the trends from 1990±***: Liver cancer accounted for 484,577 deaths worldwide in 2019 with an ASR of 5.9 per 100,000 population. China had an elevated liver cancer death ASR in 2019 and males had an ASR 1.7 times the global rate. The global ASR for DALYs peaked at 75±79 years of age but peaked earlier in China. Hepatitis B virus was the prominent etiology globally(39.5%) and in China(62.5%), followed by hepatitis C virus and alcohol consumption. In high sociodemographic index countries, non-alcoholic steatohepatitis has gained an increasing contribution as an etiologic factor. The liver cancer burden due to various etiologies has decreased globally in both genders. However, metabolic risk factors, particularly obesity, have had a growing contribution to the liver cancer burden, especially among ***: Despite an overall decreasing trend in the liver cancer burden in China and worldwide, there has been a rising contribution from metabolic risk factors, highlighting the importance of implementing targeted prevention and control strategies that address regional and gender disparities.
