Vaccination - What Can We Hope For?

We always have to be anticipating that we will see variants because historically over the last three years, we've seen multiple variants. But getting back to what I was saying a moment ago, what can we hope for? We can hope for a level of control of the infection. And you can do that by getting much greater proportion of the global population vaccinated and boosted so that hopefully after a period of time, there will be enough of a level of immunity.
