There's now an online rumor/conspiracy theory that the covid vaccine -- which she promoted with the best of intentions -- may have induced a sudden turbo-cancer in Dolly (turbo-cancers suddenly show up as Stage 4 cancers bypassing the first three stages, which has been associated with the covid vaccine).

Consume your Vitamin D-3 in generous amount (the RDA is a joke and essentially like taking nothing). Fortunately, I was already doing that well before covid struck/was-unleashed. When covid emerged, there were early recommendations that you get your D-3 levels up, but that kind of disappeared from the mainstream media pretty quickly, reemerging in the discourse later.
