That's the protocol I've been reading, and unless there is a designated driver, it's a very good idea.

Given the reports of adverse reactions, I would expect some people to faint from sheer nerves, never mind the jab, itself. It does happen.

That said, I do not trust this vaccine, particularly when we have "news" reports that prior actual illness with COVID-19 may not produce immunity. If the bug itself is insufficient to raise an immune response in a given person, the vaccine won't do it, either, because the person's immune system is incompetent.
