Will COVID be under control and over by early 2022?

to know that for certain, we would have to be able to predict the future. we would need to have some sort of vaccine, which, while people are working feverishly on it, we currently show no indications of finding one.

and even if we did, the Coronavirus would just mutate, as it has for the past century we have known about it. this is just the latest version of it, and happens to be the most deadly ever. we have never found a cure or vaccine for it yet, ever.

so the next time it mutates again, it could be less deadly, or more deadly. like i said, we cannot predict what will happen in the future. we can only hope, and pray.

You're asking two different things there, sir.

COVID-19 MAY be controlled by early 2022 IF these vaccinations prove to be as successful as many people are pinning their hopes upon, BUT COVID-19 will NOT be over by early 2022.

COVID-19 is one of a number of different Coronoviruses ... it was only given the common name COVID-19 because it was discovered in 2019.  Viruses have a tendency to mutate. i.e. they adapt to the environment in which they find themselves.  This means that COVID-19 will VERY LIKELY exist in some form for millennia ... thousands of years.

No one can assure you of that. Infections are still growing. It will likely be mid-2021 when vaccines are generally available, but it is not expected that 50% of the population will take it.
