COVID in the complex

[Puck]

Since we have so many "Drs" on here. I have a scenario for you to read through and give your answers to the questions.

A healthy middle aged woman gets covid and within days her husband also very healthy also gets covid. For a few days symptoms were not too bad. Just a mild cough runny nose and some fatigue. But after 2 days the husband takes a real turn and has a fever, sever chills (sever flu symptoms) to which he said were the worst of his life. The wife meanwhile still has the same symptoms.
After another rough day for the husband. He returns to mostly normal except for slight runny nose and a slight cough. They did not quarantine from each other at any point.

So both are able to catch the virus, and transmit the virus and one with harsh symptoms one with very lite symptoms

This is a real couple and real circumstances

So the question I would like you to answer.

1. Are either of these two people vaccinated?
