Article Abstract

Given the limitations of conventional invasive vaccines, such as the requirement for a cold chain system and trained personnel, needle-based injuries, and limited immunogenicity, non-invasive vaccines have gained significant attention. Although numerous approaches for formulating and administrating non-invasive vaccines have emerged, each of them faces its own challenges associated with vaccine bioavailability, toxicity, and other issues. To overcome such limitations, researchers have created novel supplementary materials and delivery systems. The goal of this review article is to provide vaccine formulation researchers with the most up-to-date information on vaccine formulation and the immunological mechanisms available, to identify the technical challenges associated with the commercialization of non-invasive vaccines, and to guide future research and development efforts.

For centuries, injections have been the primary method for vaccination; however, these traditional approaches present challenges due to pain, fear, and difficulties in administration. Scientists from Stanford University have developed vaccine creams, representing a revolutionary approach to the field of vaccination. Genetically modified Staphylococcus epidermidis forms the basis of these cream products, which support skin-based, painless vaccination without invasive procedures, while playing an essential role in the immune response.

Background: Lower respiratory infections (LRI) are a leading cause of death among children aged 0 to 14 globally. LRI burden estimates remain incomplete, especially in resource-limited settings.

Objective: To assess the global, regional, and national burden of LRI in children, analyse trends in incidence, mortality, and disability-adjusted life-years (DALYs), and predict future burden projections from 2022 to 2035, exploring variations in major bacterial pathogens.

Background: Cholera is a public health threat in resource-limited settings and is responsible for causing over 3 million cases globally. Mucosal immune responses play an important role in protecting against infection, a non-invasive mucosal pathogen, yet traditional plasma-based assays are invasive and logistically challenging, particularly during outbreaks in low- and middle-income countries (LMICs). Saliva offers a unique window into mucosal immunity and may serve as a non-invasive alternative for seroprevalence and vaccine immunogenicity studies.

Global public health faces substantial challenges from malignant tumors and infectious diseases. Vaccination provides an approach for treating and preventing these diseases. Oral vaccinations are particularly advantageous in disease treatment and prevention due to their non-invasive nature, high patient compliance, convenience, cost-effectiveness, and capacity to stimulate comprehensive and adaptive immune responses.

Mucosal vaccines, delivered intranasally or via inhalation, are being studied for respiratory infectious diseases like COVID-19 and influenza. These vaccines aim to provide non-invasive administration and strong immune responses at infection sites, making them a promising area of research. This systematic review and meta-analysis assessed their immunogenicity, safety, and protective efficacy.
