Actually none was done to determine Omicron. That would have occurred if either had been hospitalized. Strictly going on an assumption based on severity and duration of symptoms. Symptoms began on Monday and pretty much abated by Friday.
3 shots all Moderna, no issues at all. Son-In-Law and daughter came down with Omi Xmas day, I was with them all day, no Covid. I was boosted they were not. Their symptoms were pretty mild however.
Yes, you could still be infected BUT chances are that you may be asymptomatic or exhibit only mild symptoms. The chances are that you will not require hospitalization and your chances of death are about all but eliminated. Especially in the elderly and high risk individuals.
So, why risk not...
On Eliquis, both doses of Moderna, no issues other than I don't mask up and I enjoy going out to dinner at the Destin seafood joints with my family and friends.
