Covid meds

We had covid for the second time in October last year. All the shots and boosters. My next door neighbors two sons are doctors, and advised us to take paxlovid after our doctor said to do so also. First covid was pretty rough for both of us for four days. This time was like a cold for a few days. Was the difference the plxlovid or boosters or body resistance, I don't know, but the second time was a breeze compared to the first time. Guess our bodies are all different. We got shingle shots and my wife's arm blew up for a few days, me nothing.
