There are fantastic global efforts to fight the spread of COVID-19 through therapies and vaccines and there is much research ongoing on optimizing the vital benefits that can be conferred by these innovative ideas. One of the most encouraging ideas from recent years involves the use of mRNA (messenger RNA). Some COVID-19 vaccines are based on mRNA (which code for structures that are in, or look similar to the viral proteins and thus can be more readily and safety identified by the defence mechanisms of the cell). However, these often require complex formulations for delivery and maximum stability. This is because mRNA by itself is relatively fragile and needs protecting from being broken down once in the body.
