That's not true.
The actual quote from Newsom, as printed in the op ed you cited to, and not speculation by the author of the op ed:
"Big milestone: California now at 93% of people have at least one shot, which is something to celebrate, right?" Michaelson said. "But then when we get to that point, where is the light at the end of the tunnel, when does this state of emergency end, if we're seeing that much progress on vaccinations?"
"We'll know it when we experience it," the governor replied. "... They say about success, it's not a place or a definition, it's a direction. I mean eventually we'll get to that point, but it doesn't seem that there's a numerical match to it. It was, you know, initially it was 60%, then 70%, you add that with herd immunity, antibodies for people who haven't been vaccinated, and now we're realizing, wait a second, I mean, we're many parts, one body, what happens in South Africa can impact us here in the United States, so even if a state does well, that doesn't mean we're out of the woods.
"Look, we're making progress, California has about a third of the hospitalizations we were this time last year, less than a third of the average daily case rates than we did this time last year, that's because of our higher vaccination rates."
