Does some of the Covid-19 vaccines risk causing fertility issues?

Dr Rongjun Chen, Reader in Biomaterials Engineering, Department of Chemical Engineering, Imperial College London ( here ), told Reuters via email, through the Science Media Center ( www.sciencemediacentre.org/ ), “SM-102 present in Moderna’s mRNA vaccines is for human use, and thus different from Cayman’s SM-102 (No. 33474).”
