Is there any indication if double-vax + exposure carries similar benefit? My wife had 2x Pfizer and then she and our kids got delta. I had 2x Moderna and never had symptoms and tested negative 3 times. No quarantining whatsoever -- slept in the same bed as my wife, the kids still crawled all over me. I still got boosted a few weeks ago, but I've been curious if living in a sick-house with 100% certainty of exposure would carry its own booster effect.
