It depends on several things.
CureVac need a best case development of the vaccine candidate. Clinical studies could start early summer.
Approval standards are high, but EU commission president yesterday said
they would think about reducing "bureaucracy" in this extraordinary situation.
On the other hand, a German member of the World Health Council pointed out that approval of a new vaccine will require
1) safety and 2) efficiency of the candidate.
No way the life of young healthy persons should be at risk by reducing necessary approval time.
It would be an ethical discussion.
No way? Where's your wartime spirit? (Seriously - every member of aircrew put their lives at risk.)
