That's an excellent question, and my crystal ball is as good as yours.
Depending on the rate of vaccine deliveries, I have a feeling that we'll get there around the fall. We hope that about 85% of our population will be vaccinated by then.
Afterwards, it will be necessary to see the duration of the vaccine's protection. We have to be very honest, the phase III studies don't allow us to know the duration of protection of these vaccines. The studies showed that the duration of protection was 14 weeks. So there is protection for about three months after the second dose.
It's the ongoing monitoring that's going on that will allow us to tell how long we're protected. This doesn't necessarily mean that it'll be necessary to have a continuous reminder. It will depend on the variants and duration of protection.
According to our crystal balls, which are as good or as bad as others, we may need to be vaccinated every year, a bit like the flu, because there may be changes in the virus.
