Is it appropriate to deliver a lecture on covid-19 to high school students after the quarantine is over?

Holidays were announced from the week in which I was supposed to present the lecture, so I called the supervisor and they said they'll arrange it when holidays are over.
I'm just wondering whether or not it would still be appropriate and/or beneficial to educate high school students on the topic...
I mean I guess but what impression would you take as a student about a belated lecture?
.
Is it even really belated or is it so just in my head because I was supposed to deliver this on a specific date that's passed?
