Article Synopsis
- * A population-based study from October 2021 to March 2022 involved active surveillance, sampling, and health surveys to estimate the disease burden, revealing approximately 52,960 ARI cases, including 2,529 severe ARI (SARI) cases.
- * The findings showed higher incidence rates of ARI in those under 50 years and SARI in those 50 and older, underlining the importance of vaccination and informing health policy decisions.
Article Synopsis
- - There has been a notable drop in seasonal influenza activity globally since the COVID-19 pandemic, with a study focusing on the 2021/2022 influenza season compared to trends from 2012 to 2023.
- - Data from over 200,000 influenza surveillance cases revealed low influenza rates in the U.S. and Australia during the 2021/2022 season, but increases were seen in China, particularly with type B/Victoria dominating cases post-pandemic.
- - The study evaluated the effect of public health measures using a stringency index, showing significant individual influences on local flu activity, particularly in China, where public transport and travel restrictions played a key role.
To clarify the preferences of employees seeking influenza vaccination, a discrete choice experiment aims to understand the essential factors that close the gap between intention and behavior. A total of 866 employees with vaccination willingness willing to participated in a discrete choice experiment (DCE) between October 31st and December 6th 2022 in China including the following attributes: price, vaccination setting, appointment mode, and service time. The data was analyzed using mixed logit models.

Design: Cross-sectional survey.
Settings: Fifty-two communities/villages in the Wanzhou District, Chongqing, China, a rural area in southwest China, from May 2022 to July 2022.
Governments must decide which vaccine priority to include in their public health programs. Using the modified Delphi and entropy method, we developed an indicator framework for vaccine inclusion at the national, provincial, municipal, and district/county levels, each containing three dimensions. In total, 4 primary indicators, 17 secondary indicators, and 45 tertiary indicators were selected, covering vaccine-preventable diseases, candidate vaccines, and social drivers of the supply and demand sides.

- This study is the first to estimate how COVID-19 restrictions impacted the dynamics and susceptibility to influenza infections after those restrictions were lifted in 2022-2023.
- Using advanced modeling techniques, researchers found that the length of the influenza season was significantly shorter in 2022-2023 compared to pre-COVID seasons, while the scale of infections and population susceptibility notably increased.
- The authors suggest boosting influenza vaccination efforts and monitoring respiratory infection trends to prevent future outbreaks, particularly in vulnerable populations.
Background: Seasonal influenza activity showed a sharp decline in activity at the beginning of the emergence of COVID-19. Whether there is an epidemiological correlation between the dynamic of these 2 respiratory infectious diseases and their future trends needs to be explored.
Objective: We aimed to assess the correlation between COVID-19 and influenza activity and estimate later epidemiological trends.
Driving more WHO-recommended vaccines in the National Immunization Program: Issues and challenges in China.
Hum Vaccin Immunother
December 2023
WHO-recommended vaccines substantially prevent and control vaccine-preventable diseases (VPDs), but their inclusion differs among countries and regions. We reviewed the application for WHO-recommended vaccines in China and described the concerns and obstacles in driving the inclusion of more vaccines into China's NIP, including immunization strategies, financial barriers, vaccination services, and behavioral and social supply-side and demand-side factors. China has made significant efforts, however, they may not be sufficient until the inclusion of more WHO-recommended vaccines in the National Immunization Program (NIP), ensuring that the vaccination encompasses the whole life course of individuals, establishment of more trustworthy vaccination finance and procurement, increasing vaccine development, optimizing vaccine demand forecasts, improving the accessibility and equity of vaccination services, capturing the key points of behavioral and social drivers of vaccination on the demand side, and establishing holistic prevention and control from a public health perspective.

A self-administered electronic survey collected 17,832 participants on a media platform. We investigated the willingness of IV and used multivariate logistic regression analysis to explore its associated factors.

What Is Added By This Report?: This study investigated the willingness of children's caregivers to have their children vaccinated with pneumococcal vaccines under an innovative policy to offer 1-dose of the 13-valent pneumococcal conjugate vaccines at no charge to families.
Seasonal influenza activity typically peaks in the winter months but plummeted globally during the current coronavirus disease 2019 (COVID-19) pandemic. Unraveling lessons from influenza's unprecedented low profile is critical in informing preparedness for incoming influenza seasons. Here, we explored a country-specific inference model to estimate the effects of mask-wearing, mobility changes (international and domestic), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) interference in China, England, and the United States.

There has been scarce information to understand the future dynamics of influenza - and under different hypothesis on relaxation of non-pharmaceutical interventions (NPIs) in particular - after the disruptions to seasonal patterns.
Methods: We collected data from public sources in China, the United Kingdom, and the United States, and forecasted the influenza dynamics in the incoming 2021-2022 season under different NPIs.
The coronavirus disease 2019 (COVID-19) pandemic is a global crisis, and medical systems in many countries are overwhelmed with supply shortages and increasing demands to treat patients due to the surge in cases and severe illnesses. This study aimed to assess COVID-19-related essential clinical resource demands in China, based on different scenarios involving COVID-19 spreads and interventions. We used a susceptible-exposed-infectious-hospitalized/isolated-removed (SEIHR) transmission dynamics model to estimate the number of COVID-19 infections and hospitalizations with corresponding essential healthcare resources needed.
