Wife's Pfizer jab 1 went off without a hitch, or even a very long line. We remained in our car. Just verified her identity at the first station. Didn't even have to show her driver license or insurance card. Then we were waved into the immunization lines. Answered a few questions about allergies and such, and then a nurse injected her right through the open window. Directed into some parking spaces where we waited 15 minutes, and then back on the highway home. Very efficient.
That was five hours ago, and so far she feels fine.
