2 sons and I all tripled. My first 2 were AZ, booster Pfizer. 24 hours after the first one I went to nil battery in the space of 10 min, slept for about 12 hours and that was it. 2nd jab and booster no reaction at all. Both the boys had Pfizer for all 3; one was crook for a day after the first jab, the other nothing, and no reaction from either of them for the 2nd jab or booster.
Actually had my first ever test the other day (RAT) after a positive case was confirmed at a conference I was at last week, plus son 2 had a bit of a runny nose. Other than that I haven't had any symptoms, nor have I been anywhere that required one to produce a neg test, so I'd managed to dodge the nasal invasion!
