Freeze-drying is an effective approach to improve the long-term stability of nanomedicines. Lyoprotectants are generally considered as requisite excipients to ensure that the quality of nanoparticles is maintained throughout the freeze-drying process. However, depending on the type of nanoparticles,…

A bivalent Norovirus vaccine candidate has been developed that contains Norovirus strain GI.1 Norwalk-virus like particles (VLP) and strain GII.4 Consensus VLPadsorbed on aluminum (oxy)hydroxide. The Norwalk and Consensus antigens have different stability profiles, making it challenging to prepare a…

Oxytocin is a nonapeptide hormone used in labor to initiate uterine contractions and to prevent and treat postpartum hemorrhage. Oxytocin is currently administered by injection and requires refrigerated transport and storage, which limits access, especially during home birth in developing countries.…

Measles (Me) and rubella (Ru) viral diseases are targeted for elimination by ensuring a high level of vaccination coverage worldwide. Less costly, more convenient MeRu vaccine delivery systems should improve global vaccine coverage, especially in low – and middle – income countries (LMICs). In this…
