Through a synergistic collaboration of people with varying backgrounds and expertise, the root-cause of respiratory syncytial virus prefusion (preF) protein aggregation during freezing was identified to be supercooling. This issue was addressed through a comprehensive understanding of the product. Leveraging innovative and unconventional methods, apparatus, and approaches, it was effectively determined that key parameters influencing aggregation were the nucleation temperature and the duration of supercooling.

We previously developed a subunit vaccine antigen consisting of a stabilized trimeric influenza A group 1 hemagglutinin (H1) stem protein that elicits broadly neutralizing antibodies. Here, we further optimized the stability and manufacturability of the H1 stem antigen (H1 stem v2, also known as INFLUENZA G1 mHA) and characterized its formulation and potency with different adjuvants in vitro and in animal models.

The quality of healthcare services and outcomes in the Pacific vary widely, with some countries enjoying some of the world's longest life expectancies, others have high rates of maternal and child mortality and relatively low life expectancy. Nurses and midwives make up more than two thirds of the regional regulated healthcare workforce. This paper argues that if countries are to meet Universal Health Coverage nursing and midwifery leaders need to be explicitly involved in shaping policy at the highest levels of government to optimise individual and community health both now and in the future.
