KEVIN MCKERNAN: 25 spikes per virion. Each mRNA likely makes 10-1000s spikes given the mRNA sticks around for 709 days in some people.

from Wikipedia, 

A virion is an inert virus particle capable of invading a cell. Upon entering the cell, the virion disassembles and the genetic material from the virus takes control of the cell infrastructure, thus enabling the virus to replicate. The genetic material inside the virion is usually enclosed in a protective shell, known as the capsid.
