You never know how fast technology can advance when the entire world economy is on the line. We may see speed records broken in trials and multiple strain-specific vaccines (if the FDA slows it down then I hope the Israelis or Brits develop vaccines before the Commies do).
After the lethal polio vaccine that was pushed off on India a while back, I will require seeing a minimum of a year of testing.
Given big pharma’s track record in recent decades that is an entirely reasonable prerequisite.
