If we had known what was comming back then at the start in Jan/ Feb 2020, a consequent worldwide shut down of 4-6 weeks would have dried up this virus and would have ended the crises before it could really begin. Easy to say in retrospect.
As it is now, only collective responsibility and discipline of all humans worldwide could end the pandemic.
Responsible and disciplined behavoiur of all people? No lapses? Is that possible?
Alternatively free vaccination to all people worldwide?
Both scenarios seem out of reach.
But never fear, this way or that, all pandemics are destined to end sometime.
