Ozembic and other brands of the same drug are approved for diabetes. If I understand correctly, using it for weight loss is an "off-label" usage (not approved, but legal). From what I've read, Wegovy is a high dose version of the drug. I wonder if using the high dose version plus incorrect dosage control due to off-label use plus the patients' particulars combined to cause the problem.
Moderna's and Pfizer's Covid vaccines were fully approved by the FDA a year or two ago. I do not think J&J's vaccine was fully approved. Novavax's was authorized a year or so ago, so it might also be approved, but I'm not sure. Covid will never go away, any more than flu did after 1919 (something anybody with a quarter of a brain would have known by mid 2020), but the daily new cases are no longer being published, AFAIK, and daily deaths have been in the low 2 digits for a month or three.
