Scientists have developed an all-in-one vaccine that they hope can protect humans against a broad range of coronaviruses, including ones that are yet to emerge.

❖ This vaccine works by training the body's immune system to recognise specific regions of eight different coronaviruses, including SARS-CoV-2 which caused the COVID-19 outbreak.

❖ The new vaccine is based on a structure called a nanoparticle – a ball of proteins held together by incredibly strong interactions.

❖ Chains of different viral antigens are attached to this nanoparticle using a novel "protein superglue".
