Summary
This summary is machine-generated.Small island nations that maintained routine immunization coverage during the pandemic also achieved higher COVID-19 vaccination rates, indicating strong health systems. Sufficient health professionals and experience with new vaccine introductions are crucial for epidemic response.
Area Of Science
- Global Health
- Epidemiology
- Health Systems Research
Background
- Routine immunization (RI) performance is a key indicator of health system strength.
- Understanding the relationship between RI and epidemic vaccination is vital for assessing health system resilience.
- Small Island Developing States (SIDS) face unique challenges in maintaining health services during health crises.
Purpose Of The Study
- To examine the association between routine immunization performance and COVID-19 vaccination coverage in 55 SIDS.
- To identify factors contributing to successful vaccination campaigns during the COVID-19 pandemic in SIDS.
- To inform strategies for strengthening health systems in SIDS for future epidemic preparedness.
Main Methods
- Analysis of immunisation and health system performance data from 55 SIDS.
- Primary outcome: COVID-19 vaccination coverage at four timepoints (2021-2022).
- Examined associations with pre-pandemic RI coverage, new vaccine introductions, health workforce density, and socioeconomic factors.
Main Results
- Sustained RI coverage correlated with higher COVID-19 vaccination rates.
- Strong positive correlations found between COVID-19 vaccination coverage and physician density.
- Lower COVID-19 vaccination coverage observed in lower-income SIDS with lower development status.
Conclusions
- Countries maintaining routine immunization during the pandemic demonstrated greater health system resilience.
- Adequate numbers of skilled health professionals are essential for successful vaccination programs.
- Experience in introducing new vaccines is critical for effective epidemic response in small island settings.

Overview
Vaccination is the administration of antigenic material from pathogens to confer immunity against a specific microorganism. Vaccination primes the immune system to recognize and mount an immune response faster and more effectively if the real pathogen is encountered. Vaccinations are one of the most efficient ways to protect both individual humans and the general public from disease. A growing anti-vaccination skepticism risks the successes of vaccination programs that helped reduce...
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...
