I have cough variant asthma and the first six months of the year are usually the best for me.
I had my first Astra Zeneca jab in January and for the four weeks plus after that I felt great. My lungs felt free of pressure and I wasn’t coughing at all.
I had my second jab in early April and again a sharp reduction in the amount of coughing I usually do.
Coincidence, the fact that I haven’t really been out as listed as CEV since March last you. (Although last year I had three asthma attacks.)
I don’t know and it’s just my observation but since the two jabs my lungs have felt a lot happier!
