We had our booster shots yesterday. Must admit, my arm aches and I feel a bit fuzzy - which may just be due to lack of sleep as the arm kept waking me. Still, good to know our immunity will be going back up. After doing so well since this started, Wales seems to be the plague hotspot at the moment. That's despite fairly good adherence to social distancing and mask wearing.
A younger couple we know recently had it and were pretty rough for 3 days. As we're 25 years older than them, we would be bound to be worse. I reckon an achy breaky arm isn't a high price to pay!
