This was my third shift at the Desborough Suite vaccine clinic, and this morning the vaccine on offer was the Pfizer one, and about 600 appointments were on the system. To start with I was assigned to Pfizical fitness checking - offering blood pressure, height and weight measurement to help fill the mandatory 15 minutes post-jab attendance. Then after my break it was time for some Pfizical exercise for me - sanitising the post-jab chairs between occupants. A busy morning, but so worthwhile.
