My wife and I have had both jabs and booster, we feel fine. (Wife had Pfizer/Pfizer/Moderna, I had AZ/AZ/Moderna)
We know a lot of people that have had Covid, friends/family/neighbours. Some have still not recovered fully. One of our neighbours (now aged 30) caught Covid around 18 months ago, she cannot eat chicken anymore because the taste makes her sick, and she can no longer smell petrol.
Sadly one of my wife’s friends working on London Underground died from Covid last year.
If a second booster is offered next year, or if it becomes an annual thing, like the flu jab, then we will get the next jab.
