Impact of the COVID-19 pandemic on routine vaccination coverage under varying prevalence Conditions: A cohort study in Beijing, China
Vaccine published a retrospective cohort study conducted in Beijing. The study was categorized into a pre-COVID-19 cohort, a COVID-19 low-prevalence cohort, a COVID-19 high-prevalence cohort, and a post-COVID-19 cohort based on when the sample became eligible for vaccination, compared to baseline vaccine promptness rates through regression analysis. The study confirmed a causal association between the impact of different COVID-19 epidemic conditions on routine vaccination coverage, underlining the significance of maintaining a resilient vaccination infrastructure and initiating supplementary vaccination campaigns promptly.

Modeling the optimal seasonal monoclonal antibody administration strategy for respiratory syncytial virus (RSV) prevention based on age-season specific hospitalization rate of RSV in Suzhou, China, 2016–2022
Vaccine modeled and evaluated the effects of different vaccination strategies with monoclonal antibodies on preventing hospitalization for RSV-associated acute lower respiratory tract infections. According to the findings, the optimal mAb administration strategy season for children in Suzhou would be to administrate monoclonal antibodies to children born in July to January at birth and then to administrate the remaining children under 1 year of age in September or October.

An incentive mechanism contract model to coordinate a vaccine supply chain under demand uncertainty
The vaccine supply chain is the cornerstone of effective vaccination. This study focuses on “VSC performance improvement of India by proposing supply contracts under demand uncertainty.” The study was published in Industrial Management & Data System, in which the authors proposed three contracts of “wholesale price (WSP), cost sharing (CS) and incentive mechanism (IM)” for the government-operated immunization program in India and contextualized the models with the 2019 New Crown Epidemic in India realities of India’s new crown epidemic in 2019, showing that incentive mechanism contracts can improve the overall efficiency of the system by 23.72%.

Group-based trajectory models of integrated vaccine delivery and equity in low- and middle-income countries
Integrated vaccine delivery – the linkage of routine vaccination with other essential health services – “is a hallmark of a sound primary health care system.” In the study published in the International Journal for Equity in Health, a subset of BMC, the team used cohort-based trajectory modeling analysis to collect longitudinal data on routine immunization coverage and vaccination equity in 78 low- and middle-income countries that had previously received Gavi support for the study. The results demonstrate that vaccination equity can be significantly increased in settings with high levels of baseline inequity by implementing integrated vaccination services.

A comprehensive narrative review of challenges and facilitators in the implementation of various HPV vaccination program worldwide
This descriptive review, published in Cancer Medicine, discusses existing HPV vaccination strategies, unmet needs, challenges that need to be addressed, and collaborations that need to be reached to achieve appropriate vaccination coverage. The article highlights the significant influence that well-coordinated vaccination strategies can have on lowering disease rates globally; HPV vaccination programs “focus on adolescent girls and if possible, boys can lead to dramatic impact on disease reduction around the world.”

The immunogenicity and safety of Group B Streptococcal maternal vaccines: A systematic review
A systematic review published by Vaccine showed that all candidate vaccines against group B streptococcus (GBS) for pregnant women have good immunogenicity and safety. The most promising vaccine candidates are multivalent conjugate vaccinations based on broad-spectrum surface subunit protein vaccines or podoplanar polysaccharide (CPS) vaccines. This is because participants receiving both the podoplanar polysaccharide conjugate vaccine and the subunit vaccine showed notable differences in geometric mean IgG concentrations compared to placebo.

50th anniversary of the Expanded Programme on Immunization (EPI)
The Expanded Programme on Immunization (EPI) is an initiative launched by WHO in 1974 with the goal of ensuring that all children, regardless of geographic location or socioeconomic status, have equitable access to life-saving vaccines. Over the last 50 years, the Expanded Programme on Immunization (EPI) has evolved and achieved great success, reshaping the global health landscape.

The United States Advisory Committee on Immunization Practices issues recommended immunization schedule
In October 2023, the U.S. Advisory Committee on Immunization Practices (ACIP) approved the updated Recommended Immunization Schedule. On January 11, 2024, the U.S. Morbidity and Mortality Weekly Report released the “Immunization Schedule for Adults 19 Years of Age or Older” and the “Immunization Schedule for Children and Adolescents 18 Years of Age or Younger Immunization Program.” New appendices have been added to summarize ACIP recommendations that will be included in or amended before the next annual update of the immunization schedule.
