What's a jab?Has anyone noticed, after their first dose of the vaccine, that their fitness has decreased?
I had my vaccine on Saturday, headache on the Sunday but ears have kept on popping since.
Prior to the jab I was running 5KM at an average of 4"45/KM, now I am struggling to hit 5"05/KM
I wouldn't worry too much about loosing 20 seconds a KM in immediate aftermath seen similar or worse reported in my running club all came back after a week or two.
