i am vaxxed and of course you will still get covid if someone gives it to you, it isn't like using a condom , but the vax will help your body fight it thanks to the antibodies. i was down for a day or two when i had it a year ago. slight fever and runny nose. but then it was gone by the 3rd day and i was back to 90%. was more concerned with giving it to elderly loved ones so i isolated. also the good news is the new strains keep getting weaker and weaker. not like it was 3 years ago where good chance you ended up at ICU
with all the stress on the body of bodybuilding our immune systems are gonna be compromised. they will spread quick once the kids come back from their week off for the tgiving. give it a couple days she will be back 100%
