I watched a video (28 words)

Hi.

The original thread is here.

The following sentence is our teacher emsr2d2's version, which is perfect. I already wrote it down in my notebook.

Today, the media said that there's been a breakthrough with a potential coronavirus vaccine. All the tested volunteers have antibodies now and they are healthy.

I later recalled that I didn't hear the news from the media, but heard it when I was watching some short videos in an App. So I need to change this sentence to the factually correct version. And please take a look at it.

Today, I watched a video saying that there's been a breakthrough with a potential coronavirus vaccine and all the tested volunteers have antibodies now and they are healthy.

Is my new italic version natural and grammatical?

It's OK. You can optionally add "that" after the first "and" and (also optionally) omit "they".
