Thank you for your question. It's a very important one right now.
We don't have any models indicating when the reproduction number will drop below 1, at which point we will have reached herd immunity.
We are working on building those models. To that end, we are working with the people who are making certain projections right now. For instance, we are trying to find out the schedule for vaccine distribution. In the current context, that information is still very hard to obtain or predict.
As for your second question, it's highly important that the population follow all the public health measures as closely as possible over the next six months.
