At a very local level a friend of mine (he's 63) is unjabbed, his wife is boosted and the two kids are double jabbed (they're in their mid-20's). They ALL have Omicron but funny enough my friend is not as severe as the other 3 in the family. My brother-in-law (doctor) and his wife (insanely fit BTW) are boosted - they and 3 of the 4 kids (all under 13) got Omicron. So Omicron doesn't care how many times one goes to the gym or if you're a vegan - Omicron is just being Omicron I suppose. Key thing is that none of these folk needed to go to the quack or ER and are all recovering naturally.
