My next door neighbors apparently have Covid and two of their three kids got. Not sure if they have gotten the vaccine or not (the ten year old daughter told me last year that the flu was parroting the parents). They aren't obese people but they aren't exactly fit either so one might think Covid would be a serious issue for them. Apparently they have had it for a week and should be coming out of quarantine just fine. So if they got the vaccine, might explain why they handled it apparently better than others of their weight group. If they didn't get the vaccine, I guess not all over weight people have an issue with it.
It seems to be an unpredictable virus at times.
