Hope all is well with you and your families, Hannu and Matt.
I know a fair few of my friends’ parents who are 60+, who recently caught COVID in this delta/omicron wave in jan, who didn’t take their booster and were 9 months into their 2nd shot and just faced mild symptoms. Many were obese, one was a cancer survivor, another a smoker. 4 shots over a two year period seems slightly excessive, especially if you already got the vid. Having said that COVID has effected Indians differently compared to the west.
