Where I live in Florida(senior community) most people do like me and take 2000 units of D3 a day. Also between the pool, shuffleboard, Bocce and walking places we are in the sun quite a bit. Ne ver heard of D overdose.
My daughter has had 2 Pfizer shots but had a covid breakthrough infection. It put her in bed feeling terrible. Yesterday she went to a medical clinic and received a covid monoclonal antibody transfusion. This took about 3 hours total. This morning I talked to her she has an appetite and is doing household chores. She has to finish her 10 quarantine. She lives in Richmond VA and her insurance fully covered the treatment.
