[Research and application of the SARS-CoV-2 vaccine based on adenovirus vector technology platform].

During the global efforts to prevent and control the COVID-19 pandemic, extensive research and development of SARS-CoV-2 vaccines using various technical approaches have taken place. Among these, vaccines based on adenovirus vector have gained substantial knowledge and experience in effectively combating potential emerging infectious diseases, while also providing novel ideas and methodologies for vaccine research and development (R&D). This comprehensive review focuses on the adenovirus vector technology platform in vaccine R&D, emphasizing the importance of mucosal immunity induced by adenoviral vector-based vaccine for COVID-19 prevention. Furthermore, it analyzes the key technical challenges and obstacles encountered in the development of vaccines based on the adenovirus vector technology platform, with the aim of providing valuable insights and references for researchers and professionals in related fields.

[Thoughts and suggestions on co-administration of seasonal influenza vaccine and COVID-19 vaccine].

In the context of the global pandemic of COVID-19, the epidemic intensity, epidemic characteristics and infection risk of influenza have presented new features. COVID-19 and influenza have simultaneously emerged in many regions of the world. COVID-19 and influenza are similar in terms of transmission mode, clinical symptoms and other aspects. There are also similarities in the mechanism of influenza virus and novel coronavirus on cells. At the same time, it is feasible and significant to do a good job in the prevention and control of COVID-19 and influenza. This paper discusses the relevant strategies and measures for the joint prevention and control of influenza and novel coronavirus from the aspects of influenza vaccination to prevent co-infection, simultaneous vaccination of influenza vaccine and novel coronavirus vaccine, etc., and puts forward corresponding thoughts and suggestions, in order to provide scientific support for the formulation of strategies on seasonal influenza vaccine and novel coronavirus vaccination.

Cleaning up procedural backlogs for the elderly in a post-COVID era: a comparative review

The COVID-19 pandemic has produced massive procedural backlogs in many parts of the developed world, with a disproportionate impact on the elderly. Whereas it is well-known that such a backlog would cause undue morbidity and mortality in thousands of patients, it is still unclear how jurisdictions plan on catching up on their missed surgeries and screening tests. In this comparative review therefore, we examine existing literature to quantify the backlog and thereafter summarize the solutions that have been proposed to clear it. Searches were performed on Google, Google Scholar, PubMed, Ovid MEDLINE®, and Ovid Embase® to identify literature from Canada, the United Kingdom, and the United States of America. We report our findings with a focus on three representative types of procedures including cataract surgery, colorectal screening, and hip and knee replacement surgery. Common themes of potential solutions included leveraging more advanced technology, ensuring preventative care, training an appropriate allied health workforce, and innovating in the operating room to improve efficiency and surgical capacity. Although no single solution emerges to be universally applicable, a combination of proposed solutions can be considered after an individualized assessment of the hospital or clinic context, the type of surgery required, and the availability of equipment, facility, and staff. © 2022, University of Toronto.

[Consideration on implementation of co-administration of Seasonal Influenza and COVID-19 vaccines during pandemic in China].

Influenza is an infectious respiratory disease caused by the influenza viruses. Older people, infants and people with underlying medical conditions could have a higher risk of severe influenza symptoms and complications. The co-infection of Coronavirus Diseases 2019 (COVID-19) with influenza viruses could lead to the complication of prevention, diagnosis, control, treatment, and recovery of COVID-19. Influenza vaccine and COVID-19 vaccine overlapped in target populations, vaccination time, and inoculation units. Although there was insufficient evidence on the immunogenicity and safety of co-administration of influenza vaccine and COVID-19 vaccine, World Health Organization and some countries recommended co-administration of inactivated influenza vaccine and COVID-19 vaccine. This review summarized domestic and international vaccination policies and research progress, and put forward corresponding suggestions in order to provide scientific support for the formulation of vaccination strategy on seasonal influenza vaccine and COVID-19 vaccine.
