While most agree that vaccination is one of the most important public health practices, vaccines continue to be underused and undervalued, and vaccine-preventable diseases remain a threat to world health. Perhaps one reason this gap remains is that decision-making generally is made on a vaccine-by-vaccine basis. There has been less attention to the value of vaccination in general. To more clearly identify this value, this paper reviews the cost-effectiveness literature and calculates the annual benefits of vaccination on a global scale.

India's National COVID Vaccination Program recommended vaccination of children ages 6-12 years in April 2022. This study assessed vaccine acceptance among mothers to better understand potential barriers and facilitators of national acceptance of pediatric coronavirus disease 2019 (COVID-19) vaccination. Qualitative data were collected through three focus group discussions (FGDs) with mothers who had children younger than 12 years of age; FGD-1 was composed of mothers who worked at a tertiary medical center in India, whereas FGD-2 and FGD-3 were composed of mothers who sought care at urban and rural community health centers.

End-user feedback early in product development is important for optimizing multipurpose prevention technologies for HIV and pregnancy prevention. We evaluated the acceptability of the 90-day dapivirine levonorgestrel ring (DPV-LNG ring) used for 14 days compared to a dapivirine-only ring (DVR-200mg) in MTN-030/IPM 041 (n = 23), and when used for 90 days cyclically or continuously in MTN-044/IPM 053/CCN019 (n = 25). We enrolled healthy, non-pregnant, HIV-negative women aged 18-45 in Pittsburgh, PA and Birmingham, AL (MTN-030 only).

In biology and life sciences, fractal theory and fractional calculus have significant applications in simulating and understanding complex problems. In this paper, a compartmental model employing Caputo-type fractional and fractal-fractional operators is presented to analyze Nipah virus (NiV) dynamics and transmission. Initially, the model includes nine nonlinear ordinary differential equations that consider viral concentration, flying fox, and human populations simultaneously.

Background The study aimed to understand the acceptability, satisfaction, uptake, utility and feasibility of a quality improvement (QI) intervention to improve care for coronary heart disease (CHD) patients in Australian primary care practices and identify barriers and enablers, including the impact of COVID-19. Methods Within the QUality improvement for Effectiveness of care for people Living with heart disease (QUEL) study, 26 Australian primary care practices, supported by five Primary Health Networks (PHN) participated in a 1-year QI intervention (November 2019 - November 2020). Data were collected from practices and PHNs staff via surveys and semi-structured interviews.
