SARS-CoV-2 – the virus that causes COVID-19 – belongs to the family of betacoronaviruses that cause everything from the common cold to Mers (which kills about one in three people infected). Despite causing a wide range of symptoms, these viruses all share similarities. If they’re similar enough, could one vaccine prevent infection from them all? Scientists have certainly been considering it.
Before we explore this question, though, we first need to take a detour into the fascinating anatomy of betacoronaviruses.
Betacoronaviruses are microscopic balls covered in spikes that encapsulate a central core of genetic material. The virus must infect cells in order to replicate, and to do this it must first attach to the cells.
