Just go and ask any epidemiologist and they will tell you herd immunity is not a viable option without a vaccine. As simple as that.
Exactly.
For humanity to obtain herd immunity, billions of us would need to be infected, get sick and survive--millions of us will likely die from this approach.
Because the entire human population needs to be vaccinated, it's likely that multiple vaccines might need to be developed and administered.
Sars-CoV-2 seems to hit men harder--men tend to get sicker. And very healthy and strong men tend to get sicker because their immune system seems to overreact, attacking their own vital organs. The theory is that it could be genetic. But no one yet know for certain.
Let's hope Germany, Italy and Spain succeed in reopening their societies, slowly. But Singapore today extended its lockdown until June 1.
