most of my household down with covid.

we are all vacced, boosted with the exception of our four year old granddaughter who was due for a shot in two weeks.

Daughter and Granddaughter came to visit. The granddaughter developed fever and cough and a consult with her pediatrician led to going to the ER.

She got treated for the fever and after a few days is back to normal. Our daughter had milder symptoms.

My wife had fever, dizziness, tiredness and ended up in the ER since she had potential risk factors and her Dr after a video consult told her to head there, get a blood test for liver function and got prescribed paxlovid. Apparently it could affect the liver ??

After four days she is almost back to normal but still tired.
Amazingly enough during the whole ordeal I stayed negative .

We did mask during the day and I rented a hotel room to sleep there at night and isolate. My daughter and granddaughter are isolating in our guest bedroom

Since I stayed negative I was running errands, getting food, etc..

Maybe I'm immortal .. My brother also never caught it even thought everybody around him did.

We are both vacced and boosted but still..
I wonder if some people are lucky to be less susceptible to it.
