They didn't get their booster shots because they weren't eligible yet. They weren't at the 6-month mark. They had a breakthrough case, but so far they are still okay. They don't know what variant they have, but they lost taste and smell, on top of having fevers, etc.

My nephew, who is on leave from the Army, is staying with them. He tested negative for the virus, and he is fully vaccinated but not boosted yet. He has to test multiple times and then again when he returns to the military base. It would be a miracle if he tests negative the entire time, as perhaps the vaccine works on preventing some covid but not others. It's weird. As long as they can recover without dying or getting permanently disabled, I'm good. I'm worried though because my niece and her husband are obese, but my nephew is not (apparently, he is fit and in shape, due to being in the military and otherwise).

I think if they were boosted, they would have been able to avoid getting covid. I don't think they have omicron though, and neither do they. They think they probably have Delta.

Perhaps they were most infectious the first days of getting it, but they didn't get the test results into recently. Perhaps that could also be why my nephew still tested negative. I hope it stays that way.
