It seem difficult to understand that what biocompanies are testing is not water but a vaccine. At that stage it is a vaccine candidate but as said they’re not testing water.

BTW if i’m correct none of US covid-19 vaccines have full FDA approval. So do we call those also vaccine candidates?
Is a vaccine a candidate when it gets approval outside the US let’s say by Europe or the WHO?
