Yes, we do. There are no vaccines that have long-term consequences without having had short-term consequences, aside from the long-term consequence of immunity to the vaccine-preventable disease. Also, you have almost certainly had mild symptoms due to infection by other coronaviruses. I almost certainly have had them too. |
It doesn't have to make itself more virulent or mild. It's a myth that viruses naturally attenuate with time. |
It doesn't "have to" do anything. But there is definitely selection pressure for the virus to become more infectious and less virulent. Variants that spread easily and don't cause a lot of symptoms will outcompete variants that don't spread easily and/or make people seriously ill. |
They do. What’s the advantage of killing the host? |
No, we don’t. That’s why it usually takes many many years to make sure that a new vaccine is safe for the general public. Some viruses do cause cancer (but not right away). Nobody knows about that aspect of this novel coronavirus. |
Yep. Drinking water may cause illnesses or even death too. |
There have been no reports of any death attributed to omicron. I’d say that it is great news that the virus is wearing itself out. |
How would we know when all tests don't test for mutations. |
We are talking about covid. And, you can drink filtered water. |

It’s not a myth. It’s random mutation. |
Since omicron does not cause serious illnesses the more the merrier. It’s the best and most economic form of herd immunity considering the low vaccination rate worldwide. |
I didn't say they have to become more virulent. I said there is no pressure for it to be milder. The host dies (if it does) long after the contagious period. |
