  We have made a progressive observation of Covid-19 Astra Zeneca Vaccination
effect on Skin cellular network and properties by use of well established
Intelligent Laser Speckle Classification (ILSC) image based technique and
managed to distinguish between three different subjects groups via their laser
speckle skin image samplings such as early-vaccinated, late-vaccinated and
non-vaccinated individuals. The results have proven that the ILSC technique in
association with the optimised Bayesian network is capable of classifying skin
changes of vaccinated and non-vaccinated individuals and also of detecting
progressive development made on skin cellular properties for a month period.
