The Brazilian artist Heitor Corrêa illustrated on a 6mX14m wall in the Arch building of the Jean Jeaurès University (Toulouse, France) the thesis of a PhD student about the cytomegalovirus propagation in the human uterus in the frame of the project "My Thesis on a Wall".  The stork represents maternity and fertility. In the left eye of the stork you can notice a fetus. Finally, the snake stands for the virus as well as the antidote, just like a vaccine contains the virus that it fights against.
