Wife and I have avoided covid for awhile. I got vaccinated a few weeks ago but my wife had not yet. I got something that surfaced last weekend and tested negative but she picked it up from me and tested positive. Im thinking my recent vax may have kept the titer low enough the test did not pick it up. I was somewhat bad for a few days and have some symptoms but she is at least twice as worse. Keep in mind she had a vaccine about a year ago. We both been masking since it was showing up on reddit in 2019. Guess it was inevitable.
