Could we see a COVID-19 winter surge?

Why would there be a winter surge if more people are getting vaccinated and many have already had COVID-19?

Let's connect the dots.

Doctors say there are a few reasons. First, your immunity against COVID-19 doesn't last forever.

We still don't know how long a previous COVID-19 infection can protect you. And when it comes to the vaccine, we've already seen breakthrough infections as immunity wanes over time.

And a lot of people aren't vaccinated and that includes kids under 12 who still can't get the shot.
